    Still reduced cardiovascular mortality 12 years after supplementation with selenium and coenzyme Q10 for four years: A validation of previous 10-year follow-up results of a prospective randomized double-blind placebo-controlled trial in elderly2018In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 13, no 4, article id e0193120Article in journal (Refereed)
    Abstract [en]

    Background Selenium and coenzyme Q10 are both necessary for optimal cell function in the body. The intake of selenium is low in Europe, and the endogenous production of coenzyme Q10 decreases as age increases. Therefore, an intervention trial using selenium and coenzyme Q10 for four years as a dietary supplement was performed. The main publication reported reduced cardiovascular mortality as a result of the intervention. In the present sub-study the objective was to determine whether reduced cardiovascular (CV) mortality persisted after 12 years, in the supplemented population or in subgroups with diabetes, hypertension, ischemic heart disease or reduced functional capacity due to impaired cardiac function. Methods From a rural municipality in Sweden, four hundred forty-three healthy elderly individuals were included. All cardiovascular mortality was registered, and no participant was lost to the follow-up. Based on death certificates and autopsy results, mortality was registered. Findings After 12 years a significantly reduced CV mortality could be seen in those supplemented with selenium and coenzyme Q10, with a CV mortality of 28.1% in the active treatment group, and 38.7% in the placebo group. A multivariate Cox regression analysis demonstrated a reduced CV mortality risk in the active treatment group (HR: 0.59; 95% CI 0.42-0.81; P = 0.001). In those with ischemic heart disease, diabetes, hypertension and impaired functional capacity we demonstrated a significantly reduced CV mortality risk. Conclusions This is a 12-year follow-up of a group of healthy elderly participants that were supplemented with selenium and coenzyme Q10 for four years. Even after twelve years we observed a significantly reduced risk for CV mortality in this group, as well as in subgroups of patients with diabetes, hypertension, ischemic heart disease or impaired functional capacity. The results thus validate the results obtained in the 10-year evaluation. The protective action was not confined to the intervention period, but persisted during the follow-up period. The mechanisms behind this effect remain to be fully elucidated, although various effects on cardiac function, oxidative stress, fibrosis and inflammation have previously been identified. Since this was a small study, the observations should be regarded as hypothesis-generating.

    Less fibrosis in elderly subjects supplemented with selenium and coenzyme Q10A mechanism behind reduced cardiovascular mortality?2018In: Biofactors, ISSN 0951-6433, E-ISSN 1872-8081, Vol. 44, no 2, p. 137-147Article in journal (Refereed)
    Abstract [en]

    Background: In an intervention study where 221 healthy elderly persons received selenium and coenzyme Q10 as a dietary supplement, and 222 received placebo for 4 years we observed improved cardiac function and reduced cardiovascular mortality. As fibrosis is central in the aging process, we investigated the effect of the intervention on biomarkers of fibrogenic activity in a subanalysis of this intervention study. Material and Methods: In the present subanalysis 122 actively treated individuals and 101 controls, the effect of the treatment on eight biomarkers of fibrogenic activity were assessed. These biomarkers were: Cathepsin S, Endostatin, Galectin 3, Growth Differentiation Factor-15 (GDF-15), Matrix Metalloproteinases 1 and 9, Tissue Inhibitor of Metalloproteinases 1 (TIMP 1) and Suppression of Tumorigenicity 2 (ST-2). Blood concentrations of these biomarkers after 6 and 42 months were analyzed by the use of T-tests, repeated measures of variance, and factor analyses. Results: Compared with placebo, in those receiving supplementation with selenium and coenzyme Q10, all biomarkers except ST2 showed significant decreased concentrations in blood. The changes in concentrations, that is, effects sizes as given by partial eta(2) caused by the intervention were considered small to medium. Conclusion: The significantly decreased biomarker concentrations in those on active treatment with selenium and coenzyme Q10 compared with those on placebo after 36 months of intervention presumably reflect less fibrogenic activity as a result of the intervention. These observations might indicate that reduced fibrosis precedes the reported improvement in cardiac function, thereby explaining some of the positive clinical effects caused by the intervention.

    Less increase of copeptin and MR-proADM due to intervention with selenium and coenzyme Q10 combined: Results from a 4-year prospective randomized double-blind placebo-controlled trial among elderly Swedish citizens.2015In: Biofactors, ISSN 0951-6433, E-ISSN 1872-8081, Vol. 41, no 6, p. 443-452Article in journal (Refereed)
    Abstract [en]

    Intervention with selenium and coenzyme Q10 have recently been found to reduce mortality and increase cardiac function. The mechanisms behind these effects are unclear. As selenium and coenzyme Q10 is involved in the anti-oxidative defence, the present study aimed to evaluate effects of selenium and coenzyme Q10 on copeptin and adrenomedullin as oxidative stress biomarkers. Therefore 437 elderly individuals were included and given intervention for 4 years. Clinical examination and blood samples were undertaken at start and after 18 and 48 months. Evaluations of copeptin and MR-proADM changes were performed using repeated measures of variance. Cardiovascular mortality was evaluated using a 10-year-period of follow-up, and presented in Kaplan-Meier plots. A significant increase in copeptin level could be seen in the placebo group during the intervention period (from 9.4 pmol/L to 15.3 pmol/L), compared to the active treatment group. The difference between the groups was confirmed in the repeated measurement of variance analyses (P = 0.031) with less copeptin increase in the active treatment group. Furthermore, active treatment appeared to protect against cardiovascular death both in those with high and with low copeptin levels at inclusion. Less increase of MR-proADM could also be seen during the intervention in the active treatment group compared to controls (P=0.026). Both in those having an MR-proADM level above or below median level, significantly less cardiovascular mortality could be seen in the active treatment group (P=0.0001, and P=0.04 respectively). In conclusion supplementation with selenium and coenzyme Q10 during four years resulted in less concentration of both copeptin and MR-proADM. A cardioprotective effect of the supplementation was registered, irrespective of the initial levels of these biomarkers, and this protection was recognized also after 10 years of observation. © 2015 BioFactors, 41(6):443-452, 2015.

    Reduced Cardiovascular Mortality 10 Years after Supplementation with Selenium and Coenzyme Q10 for Four Years: Follow-Up Results of a Prospective Randomized Double-Blind Placebo-Controlled Trial in Elderly Citizens2015In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 10, no 12, p. e0141641-Article in journal (Refereed)
    Abstract [en]

    Background Selenium and coenzyme Q10 are important antioxidants in the body. As the intake of selenium is low in Europe, and the endogenous production of coenzyme Q10 decreases as age increases, an intervention trial using selenium and coenzyme Q10 for four years was performed. As previously reported, the intervention was accompanied by reduced cardiovascular mortality. The objective of the present study was to analyze cardiovascular mortality for up to 10 years after intervention, to evaluate if mortality differed in subgroups differentiated by gender, diabetes, ischemic heart disease (IHD), and functional class. Methods Four-hundred forty-three healthy elderly individuals were included from a rural municipality in Sweden. All cardiovascular mortality was registered, and no participant was lost to the follow-up. Based on death certificates and autopsy results mortality was registered. Findings Significantly reduced cardiovascular mortality could be seen in those on selenium and coenzyme Q10 intervention. A multivariate Cox regression analysis demonstrated a reduced cardiovascular mortality risk in the active treatment group (HR: 0.51; 95% CI 0.36-0.74; P = 0.0003). The reduced mortality could be seen to persist during the 10-year period. Subgroup analysis showed positive effects in both genders. An equally positive risk reduction could be seen in those with ischemic heart disease (HR: 0.51; 95% CI 0.27-0.97; P = 0.04), but also in the different functional classes. Conclusions In a 10-year follow-up of a group of healthy elderly participants given four years of intervention with selenium and coenzyme Q10, significantly reduced cardiovascular mortality was observed. The protective action was not confined to the intervention period, but persisted during the follow-up period. The mechanism explaining the persistency remains to be elucidated. Since this was a small study, the observations should be regarded as hypothesis-generating.

    Increase in insulin-like growth factor 1 (IGF-1) and insulin-like growth factor binding protein 1 after supplementation with selenium and coenzyme Q10. A prospective randomized double-blind placebo-controlled trial among elderly Swedish citizens2017In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 12, no 6, article id e0178614Article in journal (Refereed)
    Abstract [en]

    Background Insulin-like growth factor-1(IGF-1) has a multitude of effects besides cell growth and metabolism. Reports also indicate anti-inflammatory and antioxidative effects. The concentrations of IGF-1 decrease with age and during inflammation. As selenium and coenzyme Q10 are involved in both the antioxidative defense and the inflammatory response, the present study aimed to examine the effects of supplementation with selenium and coenzyme Q10 on concentrations of IGF-1 and its binding protein IGFBP-1 in a population showing reduced cardiovascular mortality following such supplementation. Methods 215 elderly individuals were included and given the intervention for four years. A clinical examination was performed and blood samples were taken at the start and after 48 months. Evaluations of IGF-1, the age adjusted IGF-1 SD score and IGFBP-1 were performed using group mean values, and repeated measures of variance. Findings After supplementation with selenium and coenzyme Q10, applying group mean evaluations, significantly higher IGF-1 and IGF-1 SD scores could be seen in the active treatment group, whereas a decrease in concentration could be seen of the same biomarkers in the placebo group. Applying the repeated measures of variance evaluations, the same significant increase in concentrations of IGF-1 (F = 68; P amp;gt; 0.0001), IGF-1 SD score (F = 29; P amp;lt; 0.0001) and of IGFBP-1 (F = 6.88; P = 0.009) could be seen, indicating the effect of selenium and coenzyme Q10 also on the expression of IGF-1 as one of the mechanistic effects of the intervention. Conclusion Supplementation with selenium and coenzyme Q10 over four years resulted in increased levels of IGF-1 and the postprandial IGFBP-1, and an increase in the age-corrected IGF-1 SD score, compared with placebo. The effects could be part of the mechanistic explanation behind the surprisingly positive clinical effects on cardiovascular morbidity and mortality reported earlier. However, as the effects of IGF-1 are complex, more research on the result of intervention with selenium and coenzyme Q10 is needed.

    Cardiovascular mortality and N-terminal-proBNP reduced after combined selenium and coenzyme Q10 supplementation: a 5-year prospective randomized double-blind placebo-controlled trial among elderly Swedish citizens2013In: International Journal of Cardiology, ISSN 0167-5273, E-ISSN 1874-1754, Vol. 167, no 5, p. 1860-1866Article in journal (Refereed)
    Abstract [en]

    Background

    Selenium and coenzyme Q10 are essential for the cell. Low cardiac contents of selenium and coenzyme Q10 have been shown in patients with cardiomyopathy, but inconsistent results are published on the effect of supplementation of the two components separately. A vital relationship exists between the two substances to obtain optimal function of the cell. However, reports on combined supplements are lacking.

    Methods

    A 5-year prospective randomized double-blind placebo-controlled trial among Swedish citizens aged 70 to 88 was performed in 443 participants given combined supplementation of selenium and coenzyme Q10 or a placebo. Clinical examinations, echocardiography and biomarker measurements were performed. Participants were monitored every 6th month throughout the intervention.

    The cardiac biomarker N-terminal proBNP (NT-proBNP) and echocardiographic changes were monitored and mortalities were registered. End-points of mortality were evaluated by Kaplan–Meier plots and Cox proportional hazard ratios were adjusted for potential confounding factors. Intention-to-treat and per-protocol analyses were applied.

    Results

    During a follow up time of 5.2 years a significant reduction of cardiovascular mortality was found in the active treatment group vs. the placebo group (5.9% vs. 12.6%; P = 0.015). NT-proBNP levels were significantly lower in the active group compared with the placebo group (mean values: 214 ng/L vs. 302 ng/L at 48 months; P = 0.014). In echocardiography a significant better cardiac function score was found in the active supplementation compared to the placebo group (P = 0.03).

    Conclusion

    Long-term supplementation of selenium/coenzyme Q10 reduces cardiovascular mortality. The positive effects could also be seen in NT-proBNP levels and on echocardiography.

    Relatively high mortality risk in elderly Swedish subjects with low selenium status2016In: European Journal of Clinical Nutrition, ISSN 0954-3007, E-ISSN 1476-5640, Vol. 70, no 1, p. 91-96Article in journal (Refereed)
    Abstract [en]

    Background/Objectives: 

    The daily dietary intake of selenium (Se), an essential trace element, is still low in Sweden in spite of decades of nutritional information campaigns and the effect of this on the public health is presently not well known. The objective of this study was to determine the serum Se levels in an elderly Swedish population and to analyze whether a low Se status had any influence on mortality.

    Subjects/Methods: 

    Six-hundred sixty-eight (n=668) elderly participants were invited from a municipality and evaluated in an observational study. Individuals were followed for 6.8 years and Se levels were re-evaluated in 98 individuals after 48 months. Clinical examination of all individuals included functional classification, echocardiography, electrocardiogram and serum Se measurement. All mortality was registered and endpoints of mortality were assessed by Kaplan–Meier plots, and Cox proportional hazard ratios adjusted for potential confounding factors were calculated.

    Results: 

    The mean serum Se level of the study population (n=668) was 67.1 μg/l, corresponding to relatively low Se intake. After adjustment for male gender, smoking, ischemic heart disease, diabetes, chronic obstructive pulmonary disease and impaired heart function, persons with serum Se in the lowest quartile had 43% (95% confidence interval (CI): 1.02–2.00) and 56% (95% CI: 1.03–2.36) increased risk for all-cause and cardiovascular mortality, respectively. The result was not driven by inflammatory effects on Se concentration in serum.

    Conclusion: 

    The mean serum Se concentration in an elderly Swedish population was 67.1 μg/l, which is below the physiological saturation level for several selenoprotein enzymes. This result may suggest the value of modest Se supplementation in order to improve the health of the Swedish population.

    Levels of sP-selectin and hs-CRP Decrease with Dietary Intervention with Selenium and Coenzyme Q10 Combined: A Secondary Analysis of a Randomized Clinical Trial2015In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 10, no 9, p. e0137680-Article in journal (Refereed)
    Abstract [en]

    Background/Objectives Inflammation and oxidative stress are central in many disease states. The major anti-oxidative enzymes contain selenium. The selenium intake in Europe is low, and supplementation with selenium and coenzyme Q(10) , important anti-oxidants, was evaluated in a previous study. The aim of this study was to evaluate response on the inflammatory biomarkers C-reactive protein, and sP-selectin, and their possible impact on cardiovascular mortality. Subjects/Methods 437 elderly individuals were included in the study. Clinical examination, echocardiography, electrocardiography and blood samples were drawn. The intervention time was 48 months, and median follow-up was 5.2 years. The effects on inflammation/atherosclerosis were evaluated through analyses of CRP and sP-selectin. Evaluations of the effect of the intervention was performed using repeated measures of variance. All mortality was registered, and endpoints of mortality were assessed by Kaplan-Meier plots. Results The placebo group showed a CRP level of 4.8 ng/mL at the start, and 5.1 ng/mL at the study end. The active supplementation group showed a CRP level of 4.1 ng/mL at the start, and 2.1 ng/mL at the study end. SP-selectin exhibited a level of 56.6mg/mL at the start in the placebo group and 72.3 mg/mL at the study end, and in the active group the corresponding figures were 55.9 mg/mL and 58.0 mg/mL. A significantly smaller increase was demonstrated through repeated measurements of the two biomarkers in those on active supplementation. Active supplementation showed an effect on the CRP and sP-selectin levels, irrespective of the biomarker levels. Reduced cardiovascular mortality was demonstrated in both those with high and low levels of CRP and sP-selectin in the active supplementation group. Conclusion CRP and sP-selectin showed significant changes reflecting effects on inflammation and atherosclerosis in those given selenium and coenzyme Q(10) combined. A reduced cardiovascular mortality could be demonstrated in the active group, irrespective of biomarker level. This result should be regarded as hypothesis-generating, and it is hoped it will stimulate more research in the area.

    Effects of long-term nocturnal oxygen treatment in patients with severe heart failure2005In: Journal of Cardiovascular Nursing, ISSN 0889-4655, E-ISSN 1550-5049, Vol. 20, no 6, p. 385-396Article in journal (Refereed)
    Abstract [en]

    Sleep-disordered breathing (SDB) is common in patients with heart failure (HF) and leads to disturbed sleep. The objective of this study was to determine the persistent effects of long-term nocturnal oxygen treatment in patients with severe HF regarding (1) objective outcomes, such as sleep, SDB, cardiac function, and functional capacity; (2) subjective outcomes, such as self-assessed sleep difficulties, daytime sleepiness, and health-related quality of life (HRQOL); and (3) the relationship between objective and subjective outcomes. In this open nonrandomized experimental study, 22 patients, median age 71 years, with severe HF were studied before and after 3 months of receiving nocturnal oxygen. The measures used were overnight polysomnography, echocardiography, 6-minute walk test, self-assessed sleep difficulties (Uppsala Sleep Inventory-HF), daytime sleepiness (Epworth Sleepiness Scale), and HRQOL (36-Item Short Form Health Survey and Minnesota Living with Heart Failure Questionnaire). SDB, with a 90% dominance of central sleep apnea, occurred in 41% of the patients with severe HF before intervention. After intervention, functional capacity improved for both the whole group of patients with HF (P < .01) and HF patients with SDB (P < .05). No improvements regarding cardiac function, objective sleep, subjective sleep, or SDB were seen, except for a decrease of > or = 4% desaturations (P < .05). HRQOL did not differ significantly between HF patients with and without SDB before or after intervention with nocturnal oxygen. Long-term nocturnal oxygen treatment improved functional capacity in patients with severe HF, with or without SDB. No improvements were seen regarding sleep, daytime sleepiness, SDB, cardiac function, or HRQOL.

    Sleep disturbances in patients with chronic heart failure and their holistic consequences-what different care actions can be implemented?2005In: European Journal of Cardiovascular Nursing, ISSN 1474-5151, E-ISSN 1873-1953, Vol. 4, no 3, p. 183-197Article in journal (Refereed)
    Abstract [en]

    Background: Sleep disturbances are prevalent among elderly, especially among those with chronic heart failure (CHF) and can affect all dimensions of quality of life (QOL) negatively. Aim: To describe the most common causes leading to sleep disturbances in patients with CHF, their consequences from a holistic perspective and different care actions that can be implemented. Methods: MEDLINE and CINAHL databases were searched from 1989 to July 2004. Findings: Sleep disordered breathing (SDB), and insomnia were the most common causes for sleep disturbances and occurs in 45-82% (SDB) and one-third (insomnia) of all patients with CHF. SDB cause a disturbed sleep structure with frequent awakenings, as well as several adverse effects on the cardiovascular system causing increased morbidity and mortality. Insomnia, caused by anxiety, an unknown life situation in relation to the debut of CHF, or symptoms/deteriorations of CHF can lead to negative effects on all aspects of QOL, as well as daytime sleepiness. Conclusion: The high prevalence of sleep disturbances and their holistic consequences should be taken into account when nurses asses and plan the care for patients with CHF. Randomized studies with large sample sizes evaluating non-pharmacological nursing interventions that improve sleep are needed. © 2005 European Society of Cardiology. Published by Elsevier B.V.

    6-month CPAP-treatment in a young male patient with severe obstructive sleep apnoea syndrome - A case study from the couples perspective2008In: European Journal of Cardiovascular Nursing, ISSN 1474-5151, E-ISSN 1873-1953, Vol. 7, no 2, p. 103-112Article in journal (Refereed)
    Abstract [en]

    Background: Obstructive sleep apnoea syndrome (OSAS) is independently associated with an increased risk for hypertension and cardiovascular disease. Continuous positive airway pressure (CPAP) can reduce mortality and morbidity, but low compliance rates are seen. Aim: To explore and describe the experiences of CPAP-treatment in a young male patient with severe OSAS during a 6-month period from the couples perspective.

    Methods and the case: A single case study with a phenomenographic approach was employed. Diagnostic procedures of OSAS and initiation of treatment with Auto-CPAP, humidifier and a nasal mask were performed during 4 visits. Conceptions were collected at 4 different occasions during the 6-month period (before, and 2 weeks, 3 months, and 6 months after treatment initiation) by means of interviews with a 33-year old male patient and his female partner.

    Findings: Totally 17 different structural aspects were found to fluctuate during the 6-month period in relation to; influence of stressors, social reactions and adaptation to increase compliance.

    Conclusion: An increased knowledge about the influence of stressors, the social reactions, and the adaptation can help healthcare personnel to identify and better understand concerns of other patients and spouses during different time phases of the initial 6-month period of CPAP-treatment.

    Obstructive sleep apnoea syndrome - Patients' perceptions of their sleep and its effects on their life situation2007In: Journal of Advanced Nursing, ISSN 0309-2402, E-ISSN 1365-2648, Vol. 57, no 3, p. 318-327Article in journal (Refereed)
    Abstract [en]

    Title. Obstructive sleep apnoea syndrome - patients' perceptions of their sleep and its effects on their life situation Aim. This paper reports a descriptive study of how untreated patients with obstructive sleep apnoea syndrome perceived their sleep situation and how the syndrome affected their life situation. Background. Obstructive sleep apnoea syndrome is a prevalent problem independently associated with an increased risk for hypertension, cardiovascular disease, chronic heart failure and mortality. Increased consumption of healthcare resources can often be seen among patients over a long period of time since many have been undiagnosed and untreated. Methods. A phenomenographic approach was employed. Data were collected by interviews during 2005 with 20 purposively selected participants with untreated obstructive sleep apnoea syndrome. Findings. Participants described loud snoring, frequent awakenings, dyspnoea, frustration over nocturia, fear of dying during sleep and partners' anxiety about the apnoea, as being night-time effects of obstructive sleep apnoea syndrome. They described dry and sore throats, tiredness and daytime sleepiness, shame about falling asleep and snoring, thoughts about complications and depressed mood as daytime effects. Needs, such as increased alertness, improved ability to concentrate, improved relationship, adequate information as well as effective treatment, were described. Participants tried self-care strategies such as information-seeking about sleep disturbances and treatment, adapted sleeping routines, change of bedroom arrangements, adapted daily schedules, hyperactivity and avoidance of difficult situations. Conclusion. The perceived effects and needs, as well as tried self-care actions by the patients with obstructive sleep apnoea syndrome in this study, could be used to identify and evaluate concerns of other patients with obstructive sleep apnoea syndrome waiting for treatment. © 2007 The Authors.

    Validation of the CPAP Habit Index-5: A Tool to Understand Adherence to CPAP Treatment in Patients with Obstructive Sleep Apnea.2014In: Sleep Disorders, ISSN 2090-3545, E-ISSN 2090-3553, Vol. 2014, p. 1-9, article id 929057Article in journal (Refereed)
    Abstract [en]

    Long-term adherence to continuous positive airway pressure (CPAP) is low among patients with obstructive sleep apnea (OSA). The potential role of "habit" in sustaining adherence to CPAP use has not been studied. This study aimed to establish the relevance of habit to CPAP adherence, via validation of an adaptation of the Self-Report Habit Index (the CPAP Habit Index-5; CHI-5). Analyses focused on the homogeneity, reliability, and factor structure of the CHI-5 and, in line with theoretical predictions, its utility as a predictor of long-term CPAP adherence in middle-aged patients with OSA. A prospective longitudinal design was used. 117 patients with objectively verified OSA intended for CPAP treatment were recruited. Data was collected via clinical examinations, respiratory recordings, questionnaires, and CPAP devices at baseline, 2 weeks, 6 months, and 12 months. The CHI-5 showed satisfactory homogeneity interitem correlations (0.42-0.93), item-total correlations (0.58-0.91), and reliability ( α = 0.92). CHI-5 data at 6 months showed a one-factor solution and predicted 63% of variance in total CPAP use hours after 12 months. Based on the satisfactory measurement properties and the high amount of CPAP use variance it explained, the CHI-5 can be seen as a useful tool in clinical practice.

    Putative facilitators and barriers for adherence to CPAP treatment in patients with obstructive sleep apnea syndrome: A qualitative content analysis2010In: SLEEP MEDICINE, ISSN 1389-9457, Vol. 11, no 2, p. 126-130Article in journal (Refereed)
    Abstract [en]

    Introduction: Effective treatment of obstructive sleep apnea syndrome (OSAS) with continuous positive airway pressure (CPAP) can reduce morbidity and mortality, but adherence rates are low without a clear consensus Of causes. Objective: To explore the experiences of adherence to CPAP treatment in patients with OSAS. Methods: A qualitative content analysis was employed. Data were collected by in-depth interviews with 23 purposively selected patients. Results: Adherence to CPAP treatment was summarized according to "facilitators" and "barriers" to CPAP treatment. Facilitators for adherence, as described by the patients were a desire to avoid symptoms, knowledge about the risk for medical consequences, fear of negative social consequences and disturbing the sleep of significant others. Other facilitators were a positive attitude to CPAP treatment, trust in healthcare personnel, a sense of engagement from the spouse and a feeling of physical improvement. Barriers included experiencing practical problems, negative psychological effects of the equipment, and negative attitudes to the treatment. Other barriers were side-effects as well as insufficient support from healthcare personnel and the spouse. Conclusion: Adherence to CPAP treatment is a multifaceted problem including patient, treatment, condition, social and healthcare related factors. Knowledge about facilitators and barriers for adherence to CPAP treatment can be used in interventional Strategies.

    Factors associated with undiagnosed obstructive sleep apnoea in hypertensive primary care patients2012In: Scandinavian Journal of Primary Health Care, ISSN 0281-3432, E-ISSN 1502-7724, Vol. 30, no 2, p. 107-113Article in journal (Refereed)
    Abstract [en]

    Objective. In hypertensive primary care patients below 65 years of age, (i) to describe the occurrence of undiagnosed obstructive sleep apnoea (OSA), and (ii) to identify the determinants of moderate/severe OSA. Design. Cross-sectional. Setting. Four primary care health centres in Sweden. Patients. 411 consecutive patients (52% women), mean age 57.9 years (SD 5.9 years), with diagnosed and treated hypertension (BP andgt; 140/90). Main outcome measures. Occurrence of OSA as measured by the apnoea hypopnoea index (AHI). Results. Mild (AHI 5-14.9/h) and moderate/severe (AHI andgt; 15/h) OSA were seen among 29% and 30% of the patients, respectively. Comparing those without OSA with those with mild or moderate/severe OSA, no differences were found in blood pressure, pharmacological treatment (anti-hypertensive, anti-depressive, and hypnotics), sleep, insomnia symptoms, daytime sleepiness, or depressive symptoms. Obesity (BMI andgt; 30 kg/m(2)) was seen in 30% and 68% of the patients with mild and moderate/severe OSA, respectively. Male gender, BMI andgt; 30 kg/m(2), snoring, witnessed apnoeas, and sleep duration andgt; 8 hours were determinants of obstructive sleep apnoea. Conclusion. Previously undiagnosed OSA is common among patients with hypertension in primary care. Obesity, snoring, witnessed apnoeas, long sleep duration, and male gender were the best predictors of OSA, even in the absence of daytime sleepiness and depressive symptoms.

    Symptom profile of undiagnosed obstructive sleep apnoea in hypertensive outpatients in primary care: a structural equation model analysis2012In: Quality in Primary Care, ISSN 1479-1072, E-ISSN 1479-1064, Vol. 20, no 4, p. 287-298Article in journal (Refereed)
    Abstract [en]

    BACKGROUND:

    Obstructive sleep apnoea (OSA) has been linked to hypertension in sleep clinic populations, but little is known about the symptom profile of undiagnosed OSA in hypertensive outpatients in primary care.

    AIM:

    To explore characteristics associated with undiagnosed  OSA in hypertensive primary care patients.

    METHODS:

    Cross-sectional design, including 411 consecutive patients (52% women), mean age 57.9 years (standard deviation [SD] 5.9 years), with diagnosed hypertension (blood pressure >140/90 mmHg) from four primary care centres. All subjects  underwent a full-night, home-based, respiratory recording to establish the presence and severity of OSA. Clinical variables, medication and comorbidities, as well as data from self-rating scales regarding symptoms/characteristics, insomnia, excessive daytime sleepiness, depressive symptoms  and health were collected during a clinical examination. Factor analyses and structural equation modelling (SEM) were used to explore the relationships between self-rated symptoms, clinical characteristics and objectively verified diagnosis of OSA. Main outcome: Measures symptom  profile of undiagnosed OSA (as measured by the Apnoea/Hypopnoea Index [AHI]) in hypertensive outpatients in primary care.

    RESULTS:

    Fifty-nine percent of the patients had an AHI ≥ 5/hour indicating OSA. An exploratory factor analysis based on 19 variables yielded a six-factor model  (anthropometrics, blood pressure, OSA-related symptoms, comorbidity, health complaints and physical activity) explaining 58% of the variance. SEM analyses showed strong significant associations between anthropometrics (body mass index, neck circumference, waist circumference) (0.45), OSA-related  symptoms (snoring, witnessed apnoeas, dry mouth) (0.47) and AHI. No direct effects of OSA on comorbidities, blood pressure, dyssomnia or self-rated health were observed.

    CONCLUSION:

    OSA was highly prevalent and was directly associated with anthropometrics and OSA-related symptoms  (snoring, witnessed apnoeas and dry mouth in the morning). When meeting patients with hypertension, these characteristics could be used by general practitioners to identify patients who are in need of referral to a sleep clinic for OSA evaluation.

    Sex-Specific Associations Between Self-reported Sleep Duration, Cardiovascular Disease, Hypertension, and Mortality in an Elderly Population.2018In: Journal of Cardiovascular Nursing, ISSN 0889-4655, E-ISSN 1550-5049, Vol. 33, no 5, p. 422-428Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Both short and long sleep durations have been associated to increased mortality. Knowledge about sex-specific differences among elderly regarding associations between sleep duration, cardiovascular health, and mortality is sparse.

    OBJECTIVE: The aims of this study are to examine the association between self-reported sleep duration and mortality and to investigate whether this association is sex specific and/or moderated by cardiovascular morbidity, and also to explore potential mediators of sleep duration effects on mortality.

    METHODS: A population-based, observational, cross-sectional design with 6-year follow-up with mortality as primary outcome was conducted. Self-rated sleep duration, clinical examinations, echocardiography, and blood samples (N-terminal fragment of proBNP) were collected. A total of 675 persons (50% women; mean age, 78 years) were divided into short sleepers (≤6 hours; n = 231), normal sleepers (7-8 hours; n = 338), and long sleepers (≥9 hours; n = 61). Data were subjected to principal component analyses. Cardiovascular disease (CVD) and hypertension factors were extracted and used as moderators and as mediators in the regression analyses.

    RESULTS: During follow-up, 55 short sleepers (24%), 68 normal sleepers (20%), and 21 long sleepers (34%) died. Mediator analyses showed that long sleep was associated with mortality in men (hazard ratio [HR], 1.8; P = .049), independently of CVD and hypertension. In men with short sleep, CVD acted as a moderator of the association with mortality (HR, 4.1; P = .025). However, when using N-terminal fragment of proBNP, this effect became nonsignificant (HR, 3.1; P = .06). In woman, a trend to moderation involving the hypertension factor and short sleep was found (HR, 4.6; P = .09).

    CONCLUSION: Short and long sleep duration may be seen as risk markers, particularly among older men with cardiovascular morbidity.

    Sex-specific associations between self-reported sleep duration, depression, anxiety, fatigue and daytime sleepiness in an older community-dwelling population2018In: Scandinavian Journal of Caring Sciences, ISSN 0283-9318, E-ISSN 1471-6712, Vol. 32, no 1, p. 290-298Article in journal (Refereed)
    Abstract [en]

    PurposeThe purpose of this study was to explore whether associations between self-reported sleep duration, depressive symptoms, anxiety, fatigue and daytime sleepiness differed in older community-dwelling men and women. DesignCross-sectional. MethodsA community-dwelling sample of 675 older men and women (mean age 77.7years, SD 3.8years) was used. All participants underwent a clinical examination by a cardiologist. Validated questionnaires were used to investigate sleep duration, depressive symptoms, anxiety, fatigue and daytime sleepiness. Subjects were divided into short sleepers (6hours), n=231; normal sleepers (7-8hours), n=338; and long sleepers (9hours), n=61. ancovas were used to explore sex-specific effects. ResultsDepressive symptoms were associated with short sleep in men, but not in women. Fatigue was associated with both short and long sleep duration in men. No sex-specific associations of sleep duration with daytime sleepiness or anxiety were found. ConclusionNurses investigating sleep duration and its correlates, or effects, in clinical practice need to take sex into account, as some associations may be sex specific. Depressive symptoms and fatigue can be used as indicators to identify older men with sleep complaints.

    Imaging congestion with a pocket ultrasound device - prognostic implications in patients with chronic heart failure.2015In: Journal of Cardiac Failure, ISSN 1071-9164, E-ISSN 1532-8414, Vol. 21, no 7, p. 548-554Article in journal (Refereed)
    Abstract [en]

    AIMS: Venous congestion is common in patients with chronic heart failure (HF). We used a pocket-sized ultrasound imaging device (PID) to assess the patient's congestive status and related our findings to prognosis.

    METHODS AND RESULTS: 104 consecutive outpatients from an HF outpatient clinic were studied. Interstitial lung water (ILW), pleural effusion (PE) and the diameter of the vena cava inferior (VCI) were assessed using a PID. ILW was assessed by demonstration of B-lines (comet tail artefact (CTA). Out of the 104 patients, 28 had CTA, and eight had PE. Median VCI diameter was 18 mm, ±14/22 mm (quartiles). Each of these parameters correlated weakly (r= 0.26-0.37, p< 0.05) with the HF biomarker NT-proBNP. During the median follow-up time of 530 days, 14 hospitalizations deaths and 7 deaths were registered. Findings of CTA, PE or a composite of both, increased the risk of death or hospitalization (hazard ratio 3-4, p< 0.05). After adjustment for age, cardiac systolic function and NT-proBNP, this difference remained significant for CTA alone and CTA + PE combined, but not for PE alone.

    CONCLUSION: By using a handheld ultrasound device, signs of pulmonary congestion could be demonstrated. When found, these had a significant prognostic impact in clinically stable HF.

    Pocket-sized ultrasound examination of fluid imbalance in patients with heart failure: A pilot and feasibility study of heart failure nurses without prior experience of ultrasonography.2015In: European journal of cardiovascular nursing : journal of the Working Group on Cardiovascular Nursing of the European Society of Cardiology, ISSN 1873-1953, Vol. 14, no 4, p. 294-302Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Detecting fluid imbalance in patients with chronic heart failure can be challenging. Use of a pocket-sized ultrasound device (PSUD) in addition to physical examination can be helpful to assess this important information.

    AIM: To evaluate the feasibility for nurses without prior experience of ultrasonography to examine fluid imbalance by the use of a PSUD on heart failure patients.

    METHOD: Four heart failure nurses and an expert cardiologist participated. The nurses underwent a four-hour PSUD training programme. One hundred and four heart failure outpatients were included. The examinations obtained information of pulmonary congestion, pleural effusion and the diameter of the vena cava inferior.

    RESULTS: Examinations took nine minutes on average. In 28% and 14% of the patients, pulmonary congestion and pleural effusion respectively were found by the nurses. The sensitivities and specificities for nurses' findings were 79% and 91%, and, 88% and 93% respectively. The inter-operator agreement between the nurses and the cardiologist reached a substantial level (kappa values: 0.71 and 0.66). The inter-operator agreement for vena cava inferior reached a fair level (kappa value=0.39). Bland-Altman plots of the level of agreement revealed a mean difference of vena cava inferior diameter of 0.11 cm, while the 95% lower and upper limits ranged from -0.78 cm to 1.00 cm.

    CONCLUSION: After brief training, heart failure nurses can reliably identify pulmonary congestion and pleural effusion with a PSUD. Assessment of vena cava inferior was less valid. PSUD readings, when added to the history and a physical examination, can improve nurse assessment of fluid status in patients with heart failure.

    Depression and cardiovascular disease: a clinical review2014In: European Heart Journal, ISSN 0195-668X, E-ISSN 1522-9645, Vol. 35, no 21, p. 1365-1372Article in journal (Refereed)
    Abstract [en]

    Cardiovascular disease (CVD) and depression are common. Patients with CVD have more depression than the general population. Persons with depression are more likely to eventually develop CVD and also have a higher mortality rate than the general population. Patients with CVD, who are also depressed, have a worse outcome than those patients who are not depressed. There is a graded relationship: the more severe the depression, the higher the subsequent risk of mortality and other cardiovascular events. It is possible that depression is only a marker for more severe CVD which so far cannot be detected using our currently available investigations. However, given the increased prevalence of depression in patients with CVD, a causal relationship with either CVD causing more depression or depression causing more CVD and a worse prognosis for CVD is probable. There are many possible pathogenetic mechanisms that have been described, which are plausible and that might well be important. However, whether or not there is a causal relationship, depression is the main driver of quality of life and requires prevention, detection, and management in its own right. Depression after an acute cardiac event is commonly an adjustment disorder than can improve spontaneously with comprehensive cardiac management. Additional management strategies for depressed cardiac patients include cardiac rehabilitation and exercise programmes, general support, cognitive behavioural therapy, antidepressant medication, combined approaches, and probably disease management programmes.

    Quality of life and symptoms of depression in advanced heartfailure patients and their partners2010In: Current Opinion in Supportive and Palliative Care, ISSN 1751-4266, Vol. 4, no 4, p. 233-237Article in journal (Refereed)
    Abstract [en]

    Purpose of review: To provide an overview of factors related to quality of life and symptoms of depression in heart failure patients and their partners. Furthermore, to give an overview of interventions that can be effective in improving their quality of life and decrease depressive symptoms.Recent findings: Quality of life of patients with heart failure and their partners is poor compared with their age-matched peers from the general population and also compared with patients suffering from other chronic diseases. Furthermore, many heart failure patients are depressed. Depressive symptoms of patients and of their partners seem to be interrelated, making interventions complicated but needed.Although the number of studies that specifically target improvement of quality of life and depression in heart failure patients and their partners is still small, several interventions are known to improve quality of life, and these could be implemented in daily care.Summary: This review considers demographic and clinical factors that are related to quality of life and depressive symptoms and addresses interventions that can contribute to improvement of quality of life of heart failure patients and their partners and decrease depressive symptoms.Education on self-care management and physical exercise are important elements of disease management programs. A multidisciplinary care approach including optimizing medical therapy and optimal symptom management is advised, focusing both on the patient and the caregiver. Treatment and care should not only focus on heart failure, but also address the consequences of co-morbidities and the side-effects of therapies.

    Health‐related quality of life, depression, sleep and breathing disorders in the elderly: With focus on those with impaired systolic function/heart failure2008Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The overall aim of this thesis was to describe the prevalence of depressive symptoms, sleep disordered breathing (SDB) and sleep complaints, as well as to investigate the prognostic value of health-related quality of life (Hr-QoL) and depressive symptoms on mortality in an elderly community living population with a focus on those with impaired systolic function/heart failure (HF). Descriptive, prognostic and explorative study designs were used to examine if a single question about global perceived health (GPH) is associated with the domains of Hr-QoL as assessed by the SF-36 (I), as well as to evaluate whether GPH provided prognostic information concerning cardiovascular mortality (II). The aim was also to evaluate if depressive symptoms are associated with mortality (III), and to describe the prevalence of SDB and its relationship to impaired systolic function, different insomnia symptoms, as well as excessive daytime sleepiness (IV).

    In primary care elderly patients with HF, GPH correlated to the physical and mental aspects of Hr-QoL. Patients who rated poor GPH also scored worse physical and mental Hr-QoL compared to patients with good GPH, but the mental aspect of Hr-QoL was however not significant (p<0.07) (I). Moreover, GPH also had an independent association with cardiovascular mortality during a ten-year follow-up. Compared to patients with good GPH, those who scored poor GPH had a four times increased risk for cardiovascular mortality (II). A total of 24% of the patients with HF suffered from depressive symptoms, not significantly different compared to 19% among those without HF. Depressive symptoms were a poor prognostic sign during the six-year follow-up and HF patients with depressive symptoms had the highest risk for cardiovascular mortality compared to HF patients without depressive symptoms (III). SDB is common among elderly people living in the community, almost one quarter (23%) had moderate or severe SDB. However, people with moderate impaired systolic function had a median apnea hypopnea index that was more than twice as high compared to those with normal systolic function (10.9 vs. 5.0, p<0.001). No obvious associations between SDB and excessive daytime sleepiness or the insomnia symptoms; difficulties maintaining sleep; non-restorative sleep; or early morning awakenings were detected. Difficulties initiating sleep were however more common in those with moderate or severe SDB (IV).

    GPH can be used as a simple tool in clinical routine practice as an aid in identifying patients in need of additional management. SDB is a common phenomenon among elderly people and associated with impaired systolic function, but with a limited impact on subjective sleep complaints. Depressive symptoms were shown to be a poor prognostic sign and may amplify the patient’s experience of suffering. Screening for depressive symptoms could therefore be an important action in the management of patients with HF.

    Abstract [en]

    Background: The aim was to examine whether a single question about global perceived health (GPH) is associated with the domains of health-related quality of life (HR-QoL) as assessed by the SF-36, and whether the scores in these domains differ from the different scores of the GPH in relation to left ventricular ejection fraction (LVEF).

    Method: The study included 412 elderly outpatients with symptoms of heart failure (HF). Echocardiography was used to determine their LVEF, and GPH was assessed by the first question on the SF-36.

    Results: The correlations between GPH and the different domains in SF-36 ranged from 0.33 to 0.64 in patients with LVEF ≥ 50% and was between 0.29 and 0.59 in patients with LVEF < 40%. Regression analyses revealed GPH to be the strongest predictor of HR-QoL. Patients with LVEF < 40% rating poor GPH differed significantly (p < 0.05) from those with good or moderate GPH in six of the eight HR-QoL domains.

    Conclusion: One question about GPH gives a good general description of HR-QoL and may therefore be used as a simple tool to assess HR-QoL in elderly outpatients with clinical symptoms of HF.

    Abstract [en]

    Introduction: Although multi-item health-related quality of life (HRQoL) instruments provide prognostic information, they are rarely used in routine clinical practice.

    Aim: To examine whether a single question about global perceived health (GPH) was a prognostic indicator of cardiovascular (CV) mortality over 10 years of follow-up in elderly patients with possible heart failure (HF) in primary care.

    Method: GPH was measured using the first question on the Short-Form-36 concerning current health status. Of the 510 patients who underwent baseline evaluation, 448 patients were included.

    Results: Cox proportional regression hazard analysis controlled for age, sex, NYHA class, diabetes, ischaemic heart disease, left ventricular ejection fraction and B-type natriuretic peptide plasma concentrations, showed that patients with GPH rated as “poor” or “good” were at four (HR 4.1 CI 95% 1.8–9.4) and three times (HR 3.4 CI 95% 1.4–7.8) the risk of CV mortality, respectively.

    Conclusion: GPH is an independent predictor of CV mortality in elderly patients with possible HF. As a complement to clinical factors when evaluating severity of HF, GPH could be an important tool for identifying patients at risk of adverse CV events and in need of improved treatment.

    Abstract [en]

    Objectives: To evaluate whether depressive symptoms (DS) in elderly patients with heart failure (HF) in the community is associated with increased mortality.

    Design: A cohort of 510 elderly patients (65-82 years) in a primary healthcare setting with symptoms associated with HF underwent a clinical and echocardiographic examination. A left ventricular ejection fraction (LVEF) <40% indicated HF. The mental health index scale was used to screen for DS. Cardiovascular and all-cause mortality was registered over 6 years.

    Results: After adjustments those with DS had an increased risk (HR) of 3.0 (CI 95% 1.6-5.5, p=0.0001) and 2.2 (CI 95% 1.3-3.7, p=0.0004) of cardiovascular and all-cause mortality, respectively. Patients with HF and DS had the highest risk of cardiovascular mortality, HR 15.7 (CI 95% 4.8-52.2) compared to patients with HF without DS and those with LVEF ≥50% and normal left ventricular diastolic function with and without DS.

    Conclusion: DS in elderly patients with HF is independently associated with increased mortality. Screening for DS is recommended as part of the clinical routine in managing patients with HF.

    Abstract [en]

    Introduction: The relationship between sleep disordered breathing (SDB), systolic function/heart failure in elderly people living in community has not been investigated, nor has insomnia and excessive daytime sleepiness (EDS).

    Aim: To describe the prevalence of SDB and its relationship to systolic function, the different insomnia symptoms as well as EDS.

    Method: 331 subjects (71-87 years) underwent echocardiographic examinations and sleep respiratory recordings. Questionnaires were used to evaluate insomnia symptoms and EDS.

    Results: Mild SDB (AHI 5-15), was found in 32%. Moderate SDB (AHI 15-30) occurred in 16%, and 7% had severe SDB (AHI >30). Median AHI was significantly higher (p<0.001) in those with mild impaired systolic function (AHI 11.7) and moderate impaired systolic function (AHI 10.9) compared to those with normal systolic function (AHI 5.0). Mild and moderate impaired systolic function was also independently associated to SDB as indicated by an AHI≥10. Concerning insomnia symptoms and EDS, only difficulties in initiating sleep correlated significantly (p<0.05) with AHI.

    Conclusion: SDB is common among the elderly and may be related to impaired systolic function/heart failure. However, detection of SDB in such population may be problematic since insomnia symptoms and EDS correlated poorly with SDB.

    Measurement of health-related quality of life in chronic heart failure, from a nursing perspective - A review of the literature2004In: European Journal of Cardiovascular Nursing, ISSN 1474-5151, E-ISSN 1873-1953, Vol. 3, no 1Article in journal (Refereed)
    Abstract [en]

    Background: Living with chronic heart failure (CHF) is distressful and affects daily life. Because of the lack of a cure for CHF, there has been a progressive interest in using health-related quality of life (Hr-QoL) as an outcome measurement of the treatment in patients with CHF. Objective: The aim of this review was to describe the instruments/questionnaires used in different studies in the measurement of Hr-QoL in patients with CHF, and how they were put into operation as seen from a nursing perspective. Method: MEDLINE and CINAHL databases were searched from January 1995 to June 2002, by using the keywords CHF, heart failure, QoL and Hr-QoL. A total of 33 articles were analysed. Results: Thirty-two different Hr-QoL questionnaires were found. Generic, disease-specific and battery approaches were different ways used to measure Hr-QoL. To assess/describe Hr-QoL, evaluate the impact of interventions and examine relations/predictors were three main objectives. However, different aspects of the concept Hr-QoL, influencing factors, how to implement the questionnaires and a lack of unified CHF criteria existed. Conclusions: To create a guideline for the measurement of Hr-QoL in CHF patients is of great importance for nurses and might generate homogeneity in the measurement methods and promote the scientific approach in the nursing care process. © 2003 European Society of Cardiology.

    Methods: a total of 331 community-dwelling elderly aged 71-87 years underwent a clinical examination and one-night polygraphic recordings in their homes. Mortality data were collected after seven years. Results: a total of 55% had SDB, 38% had OSA and 17% had CSA. Compared with those with no SDB and OSA, more participants with CSA had a left ventricular ejection fraction less than 50% (LVEF less than 50%) ischaemic heart disease (IHD) and transient ischaemic attack (TIA)/stroke. There was no difference in the rate of IHD and TIA/stroke between OSA and no SDB, but more LVEF less than 50% was found in those with OSA. CSA significantly increased the risk for all-cause (P = 0.002) and CV mortality (P = 0.018) by more than two times. After adjustments for CV disease, diabetes and the biomarker NT-pro-brain natriuretic peptide CSA associations to all-cause mortality and CV mortality lost significance. Conclusion: OSA, in persons greater than 75 years does not appear to be associated with cardiovascular disease (CVD) disease or mortality, whereas CSA might be a pathological marker of CVD and impaired systolic function associated with higher mortality.

    Sleep disordered breathing in an elderly community-living population: Relationship to cardiac function, insomnia symptoms and daytime sleepiness2009In: Sleep Medicine, ISSN 1389-9457, E-ISSN 1878-5506, Vol. 10, no 9, p. 1005-1011Article in journal (Refereed)
    Abstract [en]

    Introduction: The relationship between sleep disordered breathing (SDB), systolic function/heart failure in elderly people living in community has not been investigated, nor has insomnia and excessive daytime sleepiness (EDS).

    Aim: To describe the prevalence of SDB and its relationship to systolic function, the different insomnia symptoms as well as EDS.

    Method: 331 subjects (71-87 years) underwent echocardiographic examinations and sleep respiratory recordings. Questionnaires were used to evaluate insomnia symptoms and EDS.

    Results: Mild SDB (AHI 5-15), was found in 32%. Moderate SDB (AHI 15-30) occurred in 16%, and 7% had severe SDB (AHI >30). Median AHI was significantly higher (p<0.001) in those with mild impaired systolic function (AHI 11.7) and moderate impaired systolic function (AHI 10.9) compared to those with normal systolic function (AHI 5.0). Mild and moderate impaired systolic function was also independently associated to SDB as indicated by an AHI≥10. Concerning insomnia symptoms and EDS, only difficulties in initiating sleep correlated significantly (p<0.05) with AHI.

    Conclusion: SDB is common among the elderly and may be related to impaired systolic function/heart failure. However, detection of SDB in such population may be problematic since insomnia symptoms and EDS correlated poorly with SDB.

    Determinants of global preceived health in community-dwelling elderly screened for heart failure and sleep-disordered breathing.2010In: European Journal of Cardiovascular Nursing, ISSN 1474-5151, E-ISSN 1873-1953, Vol. 25, no 5, p. 16-26Article in journal (Refereed)
    Abstract [en]

    The relationships between heart failure (HF), sleep-disordered breathing (SDB), insomnia, depressive symptoms, and excessive daytime sleepiness (EDS), as well as their relationship to Global Perceived Health (GPH) in an elderly community-dwelling population, have not been explored. Data from 331 community-dwelling elderly (71-87 years old) were collected by echocardiography, polygraphy, and specific questionnaires. Factor analyses and structural equation modeling were used to explore the relationships between HF, SDB, sleep, psychosocial factors, and GPH. Exploratory and confirmatory factor analyses derived a 5-factor model representing SDB, insomnia, systolic function, breathlessness/physical function, and psychosocial function. Structural equation modeling analyses were used to explore the relationships between the 5 factors and to GPH. Sleep-disordered breathing had a weak effect on systolic function, but no effects on any of the other factors or GPH were found. Psychosocial function and breathlessness/physical function directly affected GPH. Indirect effects on GPH, mediated by psychosocial function, were found for breathlessness/physical function and insomnia. Systolic function also had an indirect effect on GPH. The fact that SDB in the elderly has no obvious negative associations to sleep complaints or GPH does not exclude them from being adequately treated for SDB. However, the present study has shown that SDB, by means of self-rated sleep complaints and health-related quality of life, can be problematic to detect. Psychosocial function was the most important factor for perceived GPH as it had a direct effect, as well as mediated the factors breathlessness/physical function and insomnia effects, on GPH. This study indicates that interventions in clinical practice targeting psychosocial dysfunction, such as depressive symptoms, could help to improve GPH in the elderly with or without HF.

    Vitamin D levels and depressive symptoms in patients with chronic heart failure2016In: International Journal of Cardiology, ISSN 0167-5273, E-ISSN 1874-1754, Vol. 207, p. 185-189Article in journal (Refereed)
    Abstract [en]

    Background: Vitamin D (Vit D) is suggested to play a role in the regulation of physical function as well as in depression. Since, Vit D deficiency is common in patients with heart failure (HF), this study aims to explore if Vit D levels are associated with depressive symptoms and if this association is mediated by the patients physical function. Method: 506 HF patients (mean age 71, 38% women) were investigated. Depressive symptoms and physical function were measured with the Centre for Epidemiological Studies Depression Scale and the physical function scale from the RAND-36. Vit D was measured in blood samples Results: At baseline there was no relationship between depressive symptoms and Vit D levels. However, at 18 months follow-up 29% of patients with Vit D &lt; 50 nmol/l at baseline had depressive symptoms compared 19% of those with Vit D levels &gt;50 nmol/l (p &lt; 0.05). Only in patients with Vit D &lt; 50 nmol/l, Vit D correlated significantly to physical function and depressive symptoms (r = .29, p &lt; 0.001 and r = .20, p &lt; 0.01). In structural equation modelling an indirect association between Vit D and depressive symptoms was found, mediated by physical function (B = 0.20). This association was only found in patients with Vit D levels &lt;50 nmol/l. Conclusion: In HF patients with Vit D &lt; 50 nmol/l, Vit D is associated to depressive symptoms during follow-up and this association is mediated by physical function. This relationship is not found in patients with Vitamin D level &gt;50 nmol/l. (C) 2016 Elsevier Ireland Ltd. All rights reserved.

    Difficulties in Identification of Sleep Disordered Breathing in an Outpatient Clinic for Heart Failure– A Case Study2014In: Annals of Nursing and Practice, ISSN 2379-9501, Vol. 1, no 3, article id 1011Article in journal (Refereed)
    Abstract [en]

    Sleep disordered breathing (SDB) is prevalent in patients with heart failure (HF). The clinical signs of newly diagnosed HF and untreated SDB may overlap and patients in need of SDB treatment can therefore be difficult to identify in patients participating in disease management programmes (DMP). The aim was to describe the care process of two patients with HF involved in a DMP, focusing on the difficulties to identify and initiate treatment of SDB.A prospective case study design was used to follow one male (70 yrs) and one female (74 yrs) patient during 18 months at a Swedish University hospital. It took 5 to 10 months from diagnosis of HF until optimal treatment was reached for their heart conditions and 12 to 17 months until SDB was treated. None of the patients complained of poor sleep, but suffered from fatigue. In the male SDB was detected by the wife’s complaints of her husband’s snoring, apnoeas and restless sleep. In the female, SDB was detected after a detailed assessment of fatigue which was shown to be sleepiness. After optimal treatment of HF but before imitation of SDB treatment both cases cardiac function improved. For the female case improvements also were found in the blood pressure. SDB treatment improved fatigue in both patients. Initiation of HF treatment and self-care routines, as well as identification of SDB is complex and time consuming. Treatment of HF and SDB can improve sleep, cardiac function as well as disturbing associated symptoms.

    Sleep disordered breathing, insomnia, and health related quality of life - A comparison between age and gender matched elderly with heart failure or without cardiovascular disease2010In: European Journal of Cardiovascular Nursing, ISSN 1474-5151, E-ISSN 1873-1953, Vol. 9, no 2, p. 108-117Article in journal (Refereed)
    Abstract [en]

    Aims: The aims of this study are (I) to compare the prevalence of sleep disordered breathing (SDB) and insomnia between elderly with heart failure (HF) and age and gender matched elderly without cardiovascular disease (CVD), and (II) to examine the association between HF, SDB and insomnia, as well as their impact on health related quality of life (Hr-QoL). Methods: Three hundred and thirty-one elderly (71-87 years) community-living individuals underwent sleep recordings and echocardiography. Questionnaires assessed insomnia and Hr-QoL. Comparisons were made between age and gender matched individuals with HF (n=36) and without CVD (n=36). Results: The HF group had higher mean apnoea-hypopnoea index (17.6 vs. 6.3, pless than0.001). Moderate/severe SDB was found in 42% of those with HF vs. 8% in those without CVD (p=0.001). Those with HF had more difficulties maintaining sleep (DMS) (72% vs. 50%, p=0.05) and excessive daytime sleepiness (EDS) (25% vs. 8%, p=0.05) and scored worse Hr-QoL in five of eight SF-36 domains. In regression analysis SDB had no association to Hr-QoL. DMS associated to the physical-, and non restorative sleep to the mental domain of Hr-QoL. SDB had no correlations to insomnia or EDS. Conclusions: SDB, DMS and EDS are more common in elderly with HF. SDB is not an obvious cause for sleep complaints or poor Hr-QoL in elderly.

    Global perceived health and health-related quality of life in elderly primary care patients with symptoms of heart failure2008In: European Journal of Cardiovascular Nursing, ISSN 1474-5151, E-ISSN 1873-1953, Vol. 7, no 4, p. 269-276Article in journal (Refereed)
    Abstract [en]

    Background: The aim was to examine whether a single question about global perceived health (GPH) is associated with the domains of health-related quality of life (HR-QoL) as assessed by the SF-36, and whether the scores in these domains differ from the different scores of the GPH in relation to left ventricular ejection fraction (LVEF).

    Method: The study included 412 elderly outpatients with symptoms of heart failure (HF). Echocardiography was used to determine their LVEF, and GPH was assessed by the first question on the SF-36.

    Results: The correlations between GPH and the different domains in SF-36 ranged from 0.33 to 0.64 in patients with LVEF ≥ 50% and was between 0.29 and 0.59 in patients with LVEF < 40%. Regression analyses revealed GPH to be the strongest predictor of HR-QoL. Patients with LVEF < 40% rating poor GPH differed significantly (p < 0.05) from those with good or moderate GPH in six of the eight HR-QoL domains.

    Conclusion: One question about GPH gives a good general description of HR-QoL and may therefore be used as a simple tool to assess HR-QoL in elderly outpatients with clinical symptoms of HF.

    Global perceived health and ten-year cardiovascular mortality in elderly primary care patients with possible heart failure2008In: European Journal of Heart Failure, ISSN 1388-9842, E-ISSN 1879-0844, Vol. 10, no 10, p. 1040-1047Article in journal (Refereed)
    Abstract [en]

    Introduction: Although multi-item health-related quality of life (HRQoL) instruments provide prognostic information, they are rarely used in routine clinical practice.

    Aim: To examine whether a single question about global perceived health (GPH) was a prognostic indicator of cardiovascular (CV) mortality over 10 years of follow-up in elderly patients with possible heart failure (HF) in primary care.

    Method: GPH was measured using the first question on the Short-Form-36 concerning current health status. Of the 510 patients who underwent baseline evaluation, 448 patients were included.

    Results: Cox proportional regression hazard analysis controlled for age, sex, NYHA class, diabetes, ischaemic heart disease, left ventricular ejection fraction and B-type natriuretic peptide plasma concentrations, showed that patients with GPH rated as “poor” or “good” were at four (HR 4.1 CI 95% 1.8–9.4) and three times (HR 3.4 CI 95% 1.4–7.8) the risk of CV mortality, respectively.

    Conclusion: GPH is an independent predictor of CV mortality in elderly patients with possible HF. As a complement to clinical factors when evaluating severity of HF, GPH could be an important tool for identifying patients at risk of adverse CV events and in need of improved treatment.

    The Course of Sleep Problems in Patients With Heart Failure and Associations to Rehospitalizations.2015In: Journal of Cardiovascular Nursing, ISSN 0889-4655, E-ISSN 1550-5049, Vol. 30, no 5, p. 403-410Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: Sleep problems are common in patients with heart failure (HF) and might be associated with patient outcomes.

    AIMS: The aim of this study was to describe the course of sleep problems in HF patients over 1 year and the association between sleep problems and rehospitalization.

    METHODS: Data from 499 HF patients (mean age, 70 years) were used in this analysis. Sleep problems were assessed with the item "Was your sleep restless" from the Center for Epidemiological Studies Depression Scale during hospitalization for HF (baseline) and after 1 year.

    RESULTS: A total of 43% of patients (n = 215) reported sleep problems at baseline, and 21% of patients (n = 105), after 1 year. Among the 215 patients with problems with sleep at baseline, 30% (n = 65) continued to have sleep problems over time. Among the 284 patients without sleep problems at baseline, 14% (n = 40) reported sleep problems after 1 year. After adjustments for potential cofounders, patients with continued sleep problems had an almost 2-fold increased risk for all-cause hospitalizations (hazard ratio, 2.1; P = .002) and cardiovascular hospitalizations (hazard ratio, 2.2; P = .004).

    CONCLUSION: One-third of HF patients with sleep problems at discharge experienced persistent sleep problems at follow-up. Continued sleep problems were associated with all-cause and cardiovascular rehospitalizations.

    Depressive symptoms and six-year cardiovascular mortality in elderly patients with and without heart failure2007In: Scandinavian Cardiovascular Journal, ISSN 1401-7431, E-ISSN 1651-2006, Vol. 41, no 5, p. 299-307Article in journal (Refereed)
    Abstract [en]

    Objectives: To evaluate whether depressive symptoms (DS) in elderly patients with heart failure (HF) in the community is associated with increased mortality.

    Design: A cohort of 510 elderly patients (65-82 years) in a primary healthcare setting with symptoms associated with HF underwent a clinical and echocardiographic examination. A left ventricular ejection fraction (LVEF) <40% indicated HF. The mental health index scale was used to screen for DS. Cardiovascular and all-cause mortality was registered over 6 years.

    Results: After adjustments those with DS had an increased risk (HR) of 3.0 (CI 95% 1.6-5.5, p=0.0001) and 2.2 (CI 95% 1.3-3.7, p=0.0004) of cardiovascular and all-cause mortality, respectively. Patients with HF and DS had the highest risk of cardiovascular mortality, HR 15.7 (CI 95% 4.8-52.2) compared to patients with HF without DS and those with LVEF ≥50% and normal left ventricular diastolic function with and without DS.

    Conclusion: DS in elderly patients with HF is independently associated with increased mortality. Screening for DS is recommended as part of the clinical routine in managing patients with HF.

    Consequences and predictors of depression in patients with chronic heart failure: implications for nursing care and future research.2006In: Progress in Cardiovascular Nursing, ISSN 0889-7204, E-ISSN 1751-7117, Vol. 21, no 4, p. 202-211Article in journal (Refereed)
    Abstract [en]

    Depression is common among patients with chronic heart failure (HF) and leads to more symptoms of HF, decreased quality of life, and an increased risk for premature death. Depressed HF patients also use more health care resources, which increases the economic burden on the health care system. The assessment of risk factors of depression such as age younger than 60-65 years, poor physical functioning, previous depression, poor self-efficacy, living alone, and distressful relationships, in combination with the use of depression instruments, can be helpful in detecting depression in HF patients. Unfortunately, interventions on how to relieve depression in patients with HF have not been investigated thoroughly, however, depression agents as well as HF education, social support, exercise therapy, stress management, and relaxation have been shown to be useful interventions. Because of poor outcomes, studies that examine the effectiveness and/or side effects of pharmacologic as well as nonpharmacologic interventions on depressed patients with HF are needed.

    Factors and interventions influencing health-related quality of life in patients with heart failure: A review of the literature2006In: European Journal of Cardiovascular Nursing, ISSN 1474-5151, E-ISSN 1873-1953, Vol. 5, no 1Article in journal (Refereed)
    Abstract [en]

    Introduction: Because of the lack of a cure for patients with chronic heart failure (HF), there has been a progressive interest in the use of health-related quality of life (Hr-QoL) as complementary end-point to mortality and morbidity. Aim: The aim of this review was from a nursing perspective to describe Hr-QoL and the influencing factors of Hr-QoL, as well as to identify interventions aimed at influencing Hr-QoL in HF patients. Method: Medline, Cinahl and PsycInfo databases were searched from 1995 to 2004. A total of 58 papers were included. Results: HF symptoms and activity status influence Hr-QoL negatively. However, several individual characteristics such as personality, gender and age must also be taken into consideration because different values might exist regarding what constitutes a good Hr-QoL. Nurse led interventions based on education, support and exercise can influence Hr-QoL positively. There is also a need of more studies about the effects of depression, sleep disturbances, support as well as education on Hr-QoL. There is also a need of exercise studies with larger sample sizes and older patients in higher NYHA classes. Conclusion: Several individual factors impact Hr-QoL, therefore, must nursing interventions are individually adapted to the patient's resources. © 2005 European Society of Cardiology.
