    Cost and health outcome of primary percutaneous coronary intervention versus thrombolysis in acute ST-segment elevation myocardial infarction-Results of the Swedish Early Decision reperfusion Study (SWEDES) trial2010In: AMERICAN HEART JOURNAL, ISSN 0002-8703, Vol. 160, no 2, p. 322-328Article in journal (Refereed)
    Abstract [en]

    Background In ST-elevation myocardial infarction, primary percutaneous coronary intervention (PCI) has a superior clinical outcome, but it may increase costs in comparison to thrombolysis. The aim of the study was to compare costs, clinical outcome, and quality-adjusted survival between primary PCI and thrombolysis. Methods Patients with ST-elevation myocardial infarction were randomized to primary PCI with adjunctive enoxaparin and abciximab (n = 101), or to enoxaparin followed by reteplase (n = 104). Data on the use of health care resources, work loss, and health-related quality of life were collected during a 1-year period. Cost-effectiveness was determined by comparing costs and quality-adjusted survival. The joint distribution of incremental costs and quality-adjusted survival was analyzed using a nonparametric bootstrap approach. Results Clinical outcome did not differ significantly between the groups. Compared with the group treated with thrombolysis, the cost of interventions was higher in the PCI-treated group ($4,602 vs $3,807; P = .047), as well as the cost of drugs ($1,309 vs $1,202; P = .001), whereas the cost of hospitalization was lower ($7,344 vs $9,278; P = .025). The cost of investigations, outpatient care, and loss of production did not differ significantly between the 2 treatment arms. Total cost and quality-adjusted survival were $25,315 and 0.759 vs $27,819 and 0.728 (both not significant) for the primary PCI and thrombolysis groups, respectively. Based on the 1-year follow-up, bootstrap analysis revealed that in 80%, 88%, and 89% of the replications, the cost per health outcome gained for PCI will be andlt;$0, $50,000, and $100,000 respectively. Conclusion In a 1-year perspective, there was a tendency toward lower costs and better health outcome after primary PCI, resulting in costs for PCI in comparison to thrombolysis that will be below the conventional threshold for cost-effectiveness in 88% of bootstrap replications.

    Cost of heart failure in Swedish primary healthcare2005In: Scandinavian Journal of Primary Health Care, ISSN 0281-3432, E-ISSN 1502-7724, Vol. 23, p. 227-232Article in journal (Refereed)
    Abstract [en]

    Objectives. To calculate the cost for patients with heart failure (HF) in a primary healthcare setting. Design. Retrospective study of all available patient data during a period of one year. Setting. Two healthcare centers in Linköping in the southeastern region of Sweden, covering a population of 19 400 inhabitants. Subjects. A total of 115 patients with a diagnosis of HF. Main outcome measures. The healthcare costs for patients with HF and the healthcare utilization concerning hospital days and visits to doctors and nurses in hospital care and primary healthcare. Results. The mean annual cost for a patient with HF was SEK 37 100. There were no significant differences in cost between gender, age, New York Heart Association functional class, and cardiac function. The distribution of cost was 47% for hospital care, 22% for primary healthcare, 18% for medication, 5% for nursing home, and 6% for examinations. Conclusion. Hospital care accounts for the largest cost but the cost in primary healthcare is larger than previously shown. The total annual cost for patients with HF in Sweden is in the range of SEK 5.0–6.7 billion according to this calculation, which is higher than previously known.Read More: http://informahealthcare.com/doi/abs/10.1080/02813430500197647

    Patients in primary health care diagnosed and treated as heart failure, with special reference to gender differences2001In: Scandinavian Journal of Primary Health Care, ISSN 0281-3432, E-ISSN 1502-7724, Vol. 19, no 1, p. 14-19Article in journal (Refereed)
    Abstract [en]

    Objective - The aim of the present study was to describe patients considered to have had heart failure (HF), or were being treated for HF, in a defined area in primary health care, e.g. diagnostic procedures, aetiologic diseases and management, and to evaluate whether there is a difference between the genders. Design - Descriptive retrospective investigation. Setting - ┼tvidaberg community situated in southeast Sweden, 12 400 inhabitants. Patients - 256 patients treated for symptomatic HF. Main outcome measures - Prevalence, aetiology, diagnostic procedures and management of HF and differences between the genders. Results - The diagnosis of HF was based on an objective evaluation of cardiac function in only 31% of the patients. Ischaemic heart disease (IHD) was the predominant associated disease, followed by hypertension. Therapy included diuretics (84%), angiotensin converting enzyme (ACE) inhibitors (56%) and digoxin (40%). Only 52% had optimal doses of ACE inhibitors. Women had a significantly higher mean age and their diagnoses were based on an objective diagnostic test (echocardiography) in only 20%. Women were prescribed ACE inhibitors to a lesser extent (43%) than men (64%) and with a lower optimal dose (44% versus 56% in men). Conclusion - There is still room for improvement in the management of HF in primary health care, especially in women, where the diagnosis is not generally based on an objective evaluation of cardiac function and where the treatment to a lesser extent than in men includes ACE inhibitors.

    Assessment of Suspected Aortic Stenosis by Auto Mutual Information Analysis of Murmurs2007In: Engineering in Medicine and Biology Society, 2007. EMBS 2007, 2007, p. 1945-1948Conference paper (Refereed)
    Abstract [en]

    Mild sclerotic thickening of the aortic valve affects 25% of the population, and the condition causes aortic valve stenosis (AS) in 2% of adults above 65 years. Echocardiography is today the clinical standard for assessing AS. However, a cost effective and uncomplicated technique that can be used for decision support in the primary health care would be of great value. In this study, recorded phonocardiographic signals were analyzed using the first local minimum of the auto mutual information (AMI) function. The AMI method measures the complexity in the sound signal, which is related to the amount of turbulence in the blood flow and thus to the severity of the stenosis. Two previously developed phonocardiographic methods for assessing AS severity were used for comparison, the murmur energy ratio and the sound spectral averaging technique. Twenty-nine patients with suspected AS were examined with Doppler echocardiography. The aortic jet velocity was used as a reference of AS severity, and it was found to correlate with the AMI method, the murmur energy ratio and the sound spectral averaging technique with the correlation coefficient R = 0.82, R = 0.73 and R = 0.76, respectively.

    Eptifibatide Is Noninferior to Abciximab in Primary Percutaneous Coronary Intervention Results From the SCAAR (Swedish Coronary Angiography and Angioplasty Registry)2010In: JOURNAL OF THE AMERICAN COLLEGE OF CARDIOLOGY, ISSN 0735-1097, Vol. 56, no 6, p. 470-475Article in journal (Refereed)
    Abstract [en]

    Objectives The aim of this study was to test the noninferiority of eptifibatide relative to abciximab in patients with ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). Background Glycoprotein IIb/IIIa inhibitors are recommended by international guidelines in patients with acute coronary syndromes undergoing PCI. Abciximab is recommended with a higher level of evidence than eptifibatide in patients with STEMI. No large, prospective, randomized trial comparing abciximab and eptifibatide has been published. Methods All (n = 11,479) STEMI patients in Sweden who underwent primary PCI and received either eptifibatide or abciximab from 2004 to 2007 were derived from the SCAAR ( Swedish Coronary Angiography and Angioplasty Registry). The primary end point was death or myocardial infarction (MI) during 1-year follow-up, with adjustment for baseline differences with a multivariate logistic regression analysis including propensity score. The pre-specified noninferiority margin was set to 1.29. Results The combined end point occurred in 353 of 2,355 patients (15.0%) treated with eptifibatide and in 1,432 of 9,124 patients (15.7%) treated with abciximab. The unadjusted odds ratio ( OR) for eptifibatide versus abciximab was 0.95 (95% confidence interval [CI]: 0.84 to 1.08). Multivariate adjustment (n = 11,317) confirmed noninferiority, with an OR of 0.94 ( 95% CI: 0.82 to 1.09). The adjusted secondary end points of death and MI separately also showed noninferiority, with ORs of 0.99 ( 95% CI: 0.82 to 1.19) and 0.88 ( 95% CI: 0.73 to 1.05), respectively. Conclusions This large registry study suggests that eptifibatide is noninferior to abciximab in patients with STEMI undergoing primary PCI with respect to death or MI during 1 year, thereby supporting the use of either drug in clinical practice.

    Can NT-proBNP predict risk of cardiovascular mortality within 10 years? Results from an epidemiological study of elderly patients with symptoms of heart failure2009In: International journal of cardiology, ISSN 0167-5273, Vol. 133, no 2, p. 233-240Article in journal (Refereed)
    Abstract [en]

    Background: Heart failure has a serious prognosis. However, among elderly patients the panorama of concomitant diseases makes it difficult to implement the results from epidemiological studies. The aim of this study was to evaluate the influence of different clinical variables on cardiovascular mortality during a long-term follow-up.

    Methods and results: In all, 474 elderly patients (age 65-82 years) in primary health care were evaluated and followed during a 10 year period. All patients had symptoms associated with heart failure and were examined by a cardiologist. Blood samples including NT-proBNP were analyzed, and ECG and Doppler echocardiography were assessed. Both the systolic and diastolic function was evaluated. Functional capacity was evaluated according to the NYHA classification.

    During the 10 years of follow-up those with the highest quartile of plasma concentration of NT-proBNP had almost four times increased risk of cardiovascular mortality. Impaired systolic function, diabetes and reduced functional capacity were all markers of increased risk of cardiovascular mortality. All variables were also evaluated after 5 years, with higher risk ratios for a majority of variables.

    Conclusion: In this study 474 patients with symptoms of heart failure were followed during 10 years. High plasma concentration of NT-proBNP could predict almost four times increased risk of cardiovascular mortality up to 10 years. Also, impaired cardiac function according to echocardiography, and reduced functional capacity as well as diabetes all had influence on risk of cardiovascular mortality up to 10 years.

    Cystatin C and NT-proBNP, a powerful combination of biomarkers for predicting cardiovascular mortality in elderly patients with heart failure: results from a 10-year study in primary care2009In: EUROPEAN JOURNAL OF HEART FAILURE, ISSN 1388-9842, Vol. 11, no 4, p. 354-360Article in journal (Refereed)
    Abstract [en]

    Heart failure (HF) is common among the elderly patients. It is essential to identify those at high risk in order to optimize the use of resources. We aimed to evaluate whether a combination of two biomarkers might give better prognostic information about the risk of cardiovascular (CV) mortality in patients with symptoms associated with HF, compared with only one biomarker. Four hundred and sixty-four primary health-care patients (mean age 73 years, range 65-87) with symptoms of HF were examined. All patients were evaluated using Doppler echocardiography and blood samples, including measurement of cystatin C and NT-proBNP. The patients were followed over a 10-year period. Patients with serum cystatin C levels within the highest quartile had almost three times the risk (HR: 2.92; 95% CI: 1.23-4.90) of CV mortality compared with those patients who had levels within the first, second, or third quartiles. If, at the same time, the patient had a plasma concentration of NT-proBNP within the highest quartile, the risk increased to andgt; 13 times (HR: 13.61; 95% CI: 2.56-72.24) during 10 years of follow-up or andgt; 17 times (HR: 17.04; 95% CI: 1.80-163.39) after 5 years of follow-up. Combined analysis of cystatin C and NT-proBNP could provide important prognostic information among elderly patients in the community with symptoms of HF.

    Elevated D-dimer level is an independent risk factor for cardiovascular death in out-patients with symptoms compatible with heart failure2004In: Thrombosis and Haemostasis, ISSN 0340-6245, Vol. 92, no 6, p. 1250-1258Article in journal (Refereed)
    Abstract [en]

    D-dimer, a marker of fibrin turnover, exhibits many interesting properties as a biological marker of thrombosis. Some of the properties of D-dimer might also be used to provide additional information about patients with heart failure. In this study, we evaluate the prognostic information acquired from D-dimer concerning increased risk of cardiovascular mortality in an elderly population with symptoms associated with heart failure. A cardiologist examined 458 elderly patients, out of 548 invited, attending primary care for symptoms of dyspnoea, fatigue and/or peripheral oedema and assessed NYHA functional class and cardiac function. Abnormal systolic function was defined as EF <40% on Doppler echocardiography. Abnormal diastolic function was defined as reduced E/A ratio and/or an abnormal pattern of pulmonary venous flow. Blood samples were drawn, and BNP and D-dimer were analysed. D-dimer was analysed using an automated micro-latex assay. A statistical analysis was performed to identify the prognostic value of increased plasma concentration of D-dimer. Results showed that during a median follow-up period of 5.5 years, 68 (14%) patients died of cardiovascular disease. No gender difference was noted. A plasma concentration of D-dimer >0.25mg/L increased the risk almost 4-fold. In conclusion, D-dimer is an independent risk factor for cardiovascular mortality that may be used to risk-stratify patients with heart failure. © 2004 Schattauer GmbH, Stuttgart.

    Low plasma concentrations of coagulation factors II, VII and XI indicate increased risk among elderly with symptoms of heart failure.2010In: Blood coagulation & fibrinolysis : an international journal in haemostasis and thrombosis, ISSN 1473-5733, Vol. 21, no 1, p. 62-9Article in journal (Refereed)
    Abstract [en]

    Heart failure is a serious condition, and it is, therefore, important to identify patients at high risk as early as possible in order to initiate appropriate treatment. The condition results in complicated disease mechanisms including disturbances in blood coagulation. The aim of the present study was to evaluate whether low plasma concentrations of coagulation factors (F) II, VII and XI influence cardiovascular mortality in an elderly population with possible heart failure. A cardiologist evaluated 450 elderly patients who attended primary healthcare because of symptoms associated with heart failure. He recorded new patient history, conducted a clinical examination, took blood samples, determined concentrations of B-type natriuretic peptide and FII, FVII, FXI and performed Doppler echocardiography. The patients were followed over almost a 10-year period during which all mortality was registered. In patients with suspected heart failure, those with low plasma concentrations of FII, FVII, FXI or all had a significantly higher mortality rate during the follow-up period of 10 years as compared with those with higher plasma concentrations, in contrast with findings in previous reports on patients with acute coronary syndromes. In the group with a plasma concentration of the first versus the ninth decile of FII, FVII, FXI or all, the risk of cardiovascular mortality increased two to three times.

    Prognostic Assessment of Elderly Patients with Symptoms of Heart Failure by Combining High-Sensitivity Troponin T and N-Terminal Pro-B-Type Natriuretic Peptide Measurements2010In: CLINICAL CHEMISTRY, ISSN 0009-9147, Vol. 56, no 11, p. 1718-1724Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: N-terminal pro-B-type natriuretic peptide (NT-proBNP) is a useful biomarker in heart failure assessment, whereas measurement of cardiac troponin is central in the diagnosis of patients with acute coronary syndromes. This report examined the prognostic use of combining high-sensitivity cardiac troponin T (hs-cTnT) and NT-proBNP measurements in elderly patients presenting to a primary care center with symptoms associated with heart failure. METHODS: A total of 470 elderly patients (age range 65-86 years) presenting with symptoms of heart failure were recruited from primary healthcare. In addition to clinical examination and echocardiography, hs-cTnT and NT-proBNP plasma concentrations were measured. All patients were followed for 10 years, and cardiovascular mortality was registered. RESULTS: By use of the hs-cTnT assay, 80.4% of the population had plasma concentrations above the lower detection limit of the assay. Of those displaying a plasma concentration of hs-cTnT andgt;99th percentile of a healthy population, 43% also had an NT-proBNP concentration in the fourth quartile (andgt;507 ng/L). In the multivariate analysis, we observed a 2.5-fold increased risk for cardiovascular mortality in individuals with a plasma NT-proBNP concentration andgt;507 ng/L (P andlt; 0.0001). Conversely, patients with hs-cTnT andgt;99th percentile displayed an approximately 2-fold increased risk for cardiovascular mortality (P = 0.0002). Combining the 2 biomarkers, NT-proBNP concentrations andgt;507 ng/L with hs-cTnT andgt;99th percentile increased the risk 3-fold, even after adjustment for clinical variables such as age, sex, impaired estimated glomerular filtration rate, and anemia (P andlt; 0.0001). CONCLUSIONS: hs-cTnT and NT-proBNP measurements combined provide better prognostic information than using either biomarker separately in elderly patients with symptoms associated with heart failure.

    Are There Any Significant Differences Between Females and Males in the Management of Heart Failure? Gender Aspects of an Elderly Population With Symptoms Associated With Heart Failure2009In: JOURNAL OF CARDIAC FAILURE, ISSN 1071-9164, Vol. 15, no 6, p. 501-507Article in journal (Refereed)
    Abstract [en]

    Background: An increasing interest has been shown in potential l., 11 With heart failure (HF), a serious condition for the individual. To evaluate whether there are any differences ill the prevalence of HF, cardiac function, biomarkers. and the treatment of HF with respect to gender. Methods and Results: All persons ages 70 to 80 in a rural municipality were invited to participate ill the project 876 persons accepted. Three cardiologists evaluated the patients including a new history, clinical examination. electrocardiogram, chest x-ray. blood samples. and Doppler echocardiography to assess both Systolic and diastolic function. The patients were followed during a mean period of 8 years. Conclusion: Females hypertension more frequently and included fewer smokers than their male Counterparts. A Female preponderance was seen in those with preserved systolic function. whereas males predominated among those with systolic dysfunction. During the follow-up period, 20% of the males and 14% of the females died of cardiovascular diseases. The results did not show any inferior treatment of females with HF. but it clearly was more difficult to correctly classify female patients presenting with symptoms of HE

    Reference intervals and decision limits for B-type natriuretic peptide (BNP) and its precursor (Nt-proBNP) in the elderly2007In: Clinica Chimica Acta, ISSN 0009-8981, E-ISSN 1873-3492, Vol. 382, no 1-2Article in journal (Refereed)
    Abstract [en]

    Background: Elderly patients have the highest prevalence of heart failure (HF). The aims of the study were to establish a reference interval for B-type natriuretic peptide (BNP) and (Nt-proBNP) in elderly people, and to identify clinically relevant decision limits based on long-term outcome. Methods: Plasma concentrations of BNP and Nt-proBNP were measured from two elderly populations: 218 healthy subjects (mean age 73 years, population I), and 474 patients (mean age 73 years, population II) with symptoms associated with HF. Study population II was followed for 6 years with registration of all cardiovascular mortality. Results: An association between both BNP and Nt-proBNP concentrations and age was found. The upper limit for the reference intervals in the healthy elderly (population I) was: BNP ≤ 28 pmol/L (≤ 97 ng/L), and Nt-proBNP ≤ 64 pmol/L (≤ 540 ng/L). Based on cardiovascular mortality, decision limits for BNP (∼ 50 pmol/L, ∼ 170 ng/L) and Nt-proBNP (∼ 200 pmol/L, ∼ 1700 ng/L) (population II) were determined. Conclusions: Besides establishing reference intervals for BNP and Nt-proBNP in an elderly population, a higher clinically relevant decision limit for BNP and Nt-proBNP was identified, indicating additive prognostic information of the peptides on top of measurements by echocardiography. Therefore, both reference intervals and decision limits should be included in clinical practice. © 2007.

    A clinician’s experience of using the Cardiac Reader NT-proBNP point-of-care assay in a clinical setting2008In: European Journal of Heart Failure, ISSN 1388-9842, E-ISSN 1879-0844, Vol. 10, no 3, p. 260-266Article in journal (Refereed)
    Abstract [en]

    The evaluation of natriuretic peptides has become increasingly valuable in a clinical setting, where information is often needed promptly.

    Objectives: To compare the usefulness of the recently released Roche Cardiac Reader ® NT-proBNP assay against the Roche Elecsys® NT-proBNP laboratory system in a clinical setting.

    Design and Results: Blood samples from 440 patients admitted for acute coronary syndromes, worsening of heart failure, or as policlinic heart failure patients were evaluated. The relation between the assays was analysed and the diagnostic concordance calculated. A good correlation was found between the assays (r=0.96, 95% CI: 0.94-0.97) with a diagnostic concordance of 0.93. A separate analysis was performed in the range where most clinical decisions are made (60-3000 ng/L), with a diagnostic concordance of 88%. The usefulness in a clinical setting where time is important was high.

    Conclusion: The Roche Cardiac Reader® NT-proBNP assay has been evaluated in a clinical setting. The point-of-care method shows good results, although with a restricted analytical range compared with the reference.

    Risk of cardiovascular death in elderly patients with possible heart failure. B-type natriuretic peptide (BNP) and the aminoterminal fragment of ProBNP (N-terminal proBNP) as prognostic indicators in a 6-year follow-up of a primary care population2005In: International Journal of Cardiology, ISSN 0167-5273, E-ISSN 1874-1754, Vol. 100, no 1, p. 125-133Article in journal (Refereed)
    Abstract [en]

    Heart failure is common in the elderly population and carries a serious prognosis. We evaluated EDTA-plasma B-type natriuretic peptide (brain natriuretic peptide, BNP) and the aminoterminal fragment of proBNP (N-terminal proBNP) as prognostic markers in elderly primary care patients with symptoms of heart failure. Methods: From 474 patients attending primary care for symptoms of dyspnea, fatigue and/or peripheral edema, blood was sampled in plastic tubes containing EDTA to measure BNP by non-extraction immunoradiometric assay and N-terminal proBNP by non-extraction radioimmunoassay. Patients were evaluated with respect to history and function by NYHA classification and Doppler echocardiography. Follow-up time was 6 years. Cox regression analysis was performed to identify the weight of risk variables. Conclusion: Total 6-year mortality was 20% (102 patients out of 510), and cardiovascular (CV) mortality was 14% (71 patients, 70% of total mortality). BNP and N-terminal proBNP were essentially equally useful as prognostic markers. In patients with the highest quartiles of plasma concentration of BNP and N-terminal proBNP, respectively, the risk of cardiovascular mortality was 10 and 4.8 times, respectively, higher than that in those in the lowest quartile. Peptide concentrations varied widely within all functional groups including those with normal echocardiographic findings. Plasma concentrations of BNP and N-terminal proBNP give important prognostic information concerning risk of cardiovascular mortality. Cost-effective "clinical pathways" should be outlined for patients with elevated peptide concentrations. © 2005 Elsevier Ireland Ltd. All rights reserved.

    Quality-adjusted life year weights among elderly patients with heart failure2008In: European journal of heart failure, ISSN 1388-9842, Vol. 10, no 10, p. 1033-1039Article in journal (Refereed)
    Abstract [en]

    Background

    When assessing health-related quality of life (HRQoL) in elderly patients with heart failure (HF), the process of obtaining quality-adjusted life year (QALY) weights is generally complicated and time-consuming.

    Aim

    To evaluate whether information regarding HRQoL and QALY weights can be derived directly from the established and widely used New York Heart Association (NYHA) functional classification system.

    Methods

    NYHA functional status was assessed independently both by the individual patients and by the examining cardiologist in 323 elderly patients with symptoms of HF recruited from primary care. HRQoL was evaluated using the SF-36 questionnaire and a time trade-off (TTO) scenario. The TTO technique generates direct QALY weights.

    Results

    Both the TTO technique and SF-36 values demonstrated a statistically significant correlation with NYHA functional status. The TTO values also correlated with all SF-36 dimensions. Increasing impairment was associated with statistically significant drops in both SF-36 values and TTO-based QALY weights. For patients in NYHA classes I–IV the QALY weights were 0.77, 0.68, 0.61, and 0.50, respectively. Thus in elderly patients, symptoms of HF have a major impact on perceived quality of life.

    Conclusion

    The results of the present study show that QALY weights, an important instrument in the health economic evaluation of treatment strategies, can be derived directly from NYHA classification in elderly HF patients.

    Natriuretic Peptide Biomarkers as Information Indicators in Elderly Patients With Possible Heart Failure Followed Over Six Years: A Head-to-Head Comparison of Four Cardiac Natriuretic Peptides2007In: Journal of Cardiac Failure, ISSN 1071-9164, E-ISSN 1532-8414, Vol. 13, no 6, p. 452-461Article in journal (Refereed)
    Abstract [en]

    Background: Little is known about the differences between natriuretic peptides used to evaluate elderly patients with heart failure. The aim of the study was to evaluate the information and the power to predict cardiovascular mortality derived from an analysis of cardiac natriuretic peptides from the same study population and at the same time. Methods and Results: In all, 415 elderly patients (age 65-82 years) in primary health care were evaluated and followed for 6 years. All patients had symptoms of heart failure and were examined by a cardiologist. An electrocardiogram and chest x-rays were taken, and the systolic and diastolic functions were assessed using Doppler echocardiography. Brain natriuretic peptide (BNP), N-terminal proBNP, atrial natriuretic peptide (ANP), and N-terminal proANP were analyzed. All 4 peptides were associated with age, and only 1 of them showed any gender difference. Three of the 4 peptides (not ANP) provided important information for identifying patients with impaired systolic function and diastolic dysfunction (pseudonormal or restrictive filling pattern), and for assessing the risk of cardiovascular death. Conclusions: Cardiac natriuretic peptides are useful tools for evaluating elderly patients with heart failure. Three of the 4 peptides were very similar. ANP exhibits inferior properties and cannot be recommended in clinical practice. © 2007 Elsevier Inc. All rights reserved.

    Although women are less likely to be admitted to coronary care units, they are treated equally to men and have better outcome: A prospective cohort study in patients with non ST-elevation acute coronary syndromes2009In: Acute cardiac care, ISSN 1748-295X, Vol. 11, no 3, p. 173-180Article in journal (Refereed)
    Abstract [en]

    Background: The aim of this study was to assess gender differences in admission level of care, management and outcome in patients with non ST-elevation acute coronary syndromes (NSTE-ACS), initially admitted to either coronary care units (CCU) or general wards. Method: Patients admitted to CCUs were routinely registered in the RIKS-HIA registry. In addition, patients admitted to general wards with suspected ACS were also identified and registered. Multivariable regression analysis was used to adjust for baseline differences between the genders. Results: We included 570 consecutive patients with a discharge diagnosis of NSTE-ACS. Women were less likely to be admitted to coronary care units (56% versus 69%, P=0.002), even after adjustment (odds ratio (OR), 0.65; 95% confidence interval (CI): 0.43-0.98). After adjustment for differences in baseline characteristics, women were treated similarly to men. We found no significant differences in crude short-, or long-term mortality between the genders. However, adjustment for background characteristics revealed lower one-year mortality in women (OR: 0.58; 95% CI: 0.34-0.99). Conclusion: In this study on patients with NSTE-ACS, women were less likely to be admitted to coronary care units. However, the overall treatment was as intensive for women as for men. Moreover, after adjustment, one-year mortality was lower in women.

    Similar outcome with an invasive strategy in men and women with Non ST-Elevation Acute Coronary SyndromesManuscript (preprint) (Other academic)
    Abstract [en]

    Background: Gender differences in benefit from an early invasive strategy in patients with Non ST-elevation Acute Coronary Syndromes (NSTE ACS) have been debated and results are conflicting. Some studies have even indicated harm for women associated with a routine invasive strategy.

    Method: We included 46 455 patients ( 14 819 women (32%) and 31 636 men (68%)) from The Register of Information and Knowledge about Swedish Heart Intensive care Admissions (RIKS-HIA), with a diagnosis of either unstable angina pectoris or non-ST-elevation myocardial infarction. All patients were admitted to intensive coronary care units in Sweden, between 2000 and 2006, and followed for 1 year. Adjustment for baseline differences between the genders was made.

    Results: In the non-invasive strategy arm relative risk (RR) of death was (women vs. men) 1.02 (95% CI, 0.94-1.11) and in the invasive strategy arm 1.12 (95% CI, 0.96-1.29). After adjustment for baseline differences between the genders with propensity score and discharge medication there was a trend towards lower mortality among women, RR 0.90 (95% CI, 0.82-0.99) in the early non-invasive group but still no difference in the early invasive cohort RR 0.90 (95% CI, 0.76-1.06). Results were similar with the combined end-point death/MI. The risk reduction with an invasive strategy was similar in women (RR 0.46 (95% CI 0.38-0.55)) and men (RR 0.45 (95% CI 0.40-0.52).

    Conclusion: In this large cohort of patients with NSTE ACS, reflecting real life management, women and men had similar outcome and similar benefit with an early invasive strategy.

    Gender differences in management and outcome in non-ST-elevation acute coronary syndrome2007In: Heart, ISSN 1355-6037, E-ISSN 1468-201X, Vol. 93, no 11, p. 1357-1362Article in journal (Refereed)
    Abstract [en]

    Objective: To study gender differences in management and outcome in patients with non-ST-elevation acute coronary syndrome. Design, setting and patients: Cohort study of 53 781 consecutive patients (37% women) from the Register of Information and Knowledge about Swedish Heart Intensive care Admissions (RIKS-HIA), with a diagnosis of either unstable angina pectoris or non-ST-elevation myocardial infarction. All patients were admitted to intensive coronary care units in Sweden, between 1998 and 2002, and followed for 1 year. Main outcome measures: Treatment intensity and in-hospital, 30-day and 1 -year mortality. Results: Women were older (73 vs 69 years, p<0.001) and more likely to have a history of hypertension and diabetes, but less likely to have a history of myocardial infarction or revascularisation. After adjustment, there were no major differences in acute pharmacological treatment or prophylactic medication at discharge. Revascularisation was, however, even after adjustment, performed more often in men (OR 1.15, 95% CI, 1.09 to 1.21). After adjustment, there was no significant difference in in-hospital (OR 1.03, 95% CI, 0.94 to 1.13) or 30-days (OR 1.07, 95% CI, 0.99 to 1.15) mortality, but at 1 year being male was associated with higher mortality (OR 1.12, 95% CI, 1.06 to 1.19). Conclusion: Although women are somewhat less intensively treated, especially regarding invasive procedures, after adjustment for differences in background characteristics, they have better long-term outcomes than men.

    Abstract [en]

    Acute Coronary Syndromes are the most frequent manifestations of coronary heart disease (CHD). Gender differences in treatment intensity, including differences in level of care, have been reported. Also differences in benefit from certain treatments, especially invasive treatment, have been discussed. Finally, differences in outcome between men and women have been proposed. Results have been inconsistent, partly depending on if and how adjustment for differences in background characteristics has been made.

    Editorial: Does atrioventricular ring motion always distinguish constriction from restriction? A Doppler myocardial imaging study2001In: Journal of the American Society of Echocardiography, ISSN 0894-7317, E-ISSN 1097-6795, Vol. 14, no 5, p. 391-395Article in journal (Other academic)
    Abstract [en]

    Constrictive pericarditis and restrictive cardiomyopathy can be difficult to differentiate on clinical examination. Cardiac ultrasonography is increasingly being used as the noninvasive method of choice for confirming the specific morphologic and hemodynamic abnormalities associated with either condition. Interrogation of atrioventricular valve plane motion by Doppler myocardial imaging (DMI) has been suggested as a valuable new approach that can help differentiate one from the other. We report the color DMI, pulsed DMI, and strain rate findings in 2 cases of constrictive pericarditis in which consideration of the annular motion pattern alone would not have allowed such differentiation.

    Nephrotoxic effects in high-risk patients undergoing angiography2003In: New England Journal of Medicine, ISSN 0028-4793, E-ISSN 1533-4406, Vol. 348, no 6, p. 491-499Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: The use of iodinated contrast medium can result in nephropathy. Whether iso-osmolar contrast medium is less nephrotoxic than low-osmolar contrast medium in high-risk patients is uncertain. METHODS: We conducted a randomized, double-blind, prospective, multicenter study comparing the nephrotoxic effects of an iso-osmolar, dimeric, nonionic contrast medium, iodixanol, with those of a low-osmolar, nonionic, monomeric contrast medium, iohexol. The study involved 129 patients with diabetes with serum creatinine concentrations of 1.5 to 3.5 mg per deciliter who underwent coronary or aortofemoral angiography. The primary end point was the peak increase from base line in the creatinine concentration during the three days after angiography. Other end points were an increase in the creatinine concentration of 0.5 mg per deciliter or more, an increase of 1.0 mg per deciliter or more, and a change in the creatinine concentration from day 0 to day 7. RESULTS: The creatinine concentration increased significantly less in patients who received iodixanol. From day 0 to day 3, the mean peak increase in creatinine was 0.13 mg per deciliter in the iodixanol group and 0.55 mg per deciliter in the iohexol group (P=0.001, the increase with iodixanol minus the increase with iohexol, -0.42 mg per deciliter [95 percent confidence interval, -0.73 to -0.22]). Two of the 64 patients in the iodixanol group (3 percent) had an increase in the creatinine concentration of 0.5 mg per deciliter or more, as compared with 17 of the 65 patients in the iohexol group (26 percent) (P=0.002, odds ratio for such an increase in the iodixanol group, 0.09 [95 percent confidence interval, 0.02 to 0.41]). No patient receiving iodixanol had an increase of 1.0 mg per deciliter or more, but 10 patients in the iohexol group (15 percent) did. The mean change in the creatinine concentration from day 0 to day 7 was 0.07 mg per deciliter in the iodixanol group and 0.24 mg per deciliter in the iohexol group (P=0.003, value in the iodixanol group minus the value in the iohexol group, -0.17 mg per deciliter [95 percent confidence interval, -0.34 to -0.07]). CONCLUSIONS: Nephropathy induced by contrast medium may be less likely to develop in high-risk patients when iodixanol is used rather than a low-osmolar, nonionic contrast medium.

    Cost-effectiveness of iodixanol in patients at high risk of contrast-induced nephropathy2005In: American Heart Journal, ISSN 0002-8703, E-ISSN 1097-6744, Vol. 149, no 2, p. 298-303Article, review/survey (Refereed)
    Abstract [en]

    Background: Acute renal failure after contrast-induced nephropathy is a clinically important and costly complication after the use of iodine-based contrast media. We investigated the cost and cost-effectiveness of 2 contrast media in patients at high risk of contrast-induced nephropathy. Methods: The analyses were based on a randomized, prospective, multinational clinical study comparing the nephrotoxic effects of an isosmolar nonionic contrast medium, iodixanol, with those of a low-osmolar nonionic contrast medium, iohexol. Resource utilization data were obtained from the study and from a retrospective review of patients' hospital records. Swedish, German, and French unit prices were applied to resources used. Between-group differences in average costs were analyzed using a nonparametric bootstrap method. Results: Resource utilization data for 125 patients were analyzed. Seven contrast media-related serious adverse reactions, of which 6 were acute renal failures, were noted in 6 patients receiving iohexol. Two patients in the iodixanol group had 1 nonserious reaction each. The mean hospitalization cost per patient was €489, €573, and €393 lower after iodixanol than after iohexol using Swedish, German, and French unit prices, respectively. The mean per-patient costs of treating adverse drug reactions were €371, €399, and €445 lower after iodixanol than after iohexol, using the respective unit prices (P = 0.01). Iodixanol was cost-effective compared with iohexol, with both lower costs and better effects related to fewer adverse drug reactions. Conclusions: The isosmolar contrast medium iodixanol appears to be cost-effective when compared with a low-osmolar contrast medium, iohexol, in diabetic patients with renal impairment undergoing angiography. © 2005, Elsevier Inc.

    European cardiovascular nurses experiences of and attitudes towards having family members present in the resuscitation room2010In: EUROPEAN JOURNAL OF CARDIOVASCULAR NURSING, ISSN 1474-5151, Vol. 9, no 1, p. 15-23Article in journal (Refereed)
    Abstract [en]

    Purpose: To investigate cardiovascular nurses experiences of and attitudes towards the presence of family members during resuscitation of adult patients. Methods: A 36-item questionnaire exploring the experiences of and attitudes towards family members being present in the resuscitation room was distributed to a convenience sample of nurses attending three national and one international cardiovascular nursing conferences held in Europe during 2007. Results: Of 820 questionnaires distributed, 411(50%) completed ones were returned. Of these 411 respondents, 178 (44%) had experienced at least one situation of families being present. Positive (23%) and negative (21%) experiences of family presence were equally distributed. Only 28 (7%) respondents stated that their unit had a protocol covering family presence. Nurses in Ireland (n=30; 59%) and the UK (n=18; 55%) were most likely to have experienced family presence and protocols relating to this were most commonly found in the UK (n=4; 14%). Conclusion: Less than half of the included European cardiovascular nurses had experienced a situation of families being present during resuscitation and protocols pertaining to this were rare. There was no clear attitude towards family presence, though experience in nursing made nurses more favourable towards it.
