    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.

    The measurement and prevalence of depression in patients with chronic heart failure.2006In: Progress in Cardiovascular Nursing, ISSN 0889-7204, E-ISSN 1751-7117, Vol. 21, no 1, p. 28-36Article in journal (Refereed)
    Abstract [en]

    Chronic heart failure is a common disease accompanied by poor mental health and depression. The diagnosis of depression is based on the presence of affective, cognitive, and somatic symptoms assessed by categoric or dimensional instruments. Depression is prominent and high rates are found with dimensional instruments in hospitalized heart failure patients. Categoric instruments seem to be more reliable but are more complex to use. Because of poor outcomes, attention should also be paid to subthreshold depression. In screening for such cases, dimensional instruments might be preferable because of the risk for underestimation by categoric instruments. Dimensional instruments might also be easier to implement in daily practice but, to reduce bias, cutoff scores might need refinement according to the clinical setting. Therefore, studies that evaluate different cutoff values are needed to find a critical level of burden from a depressive symptomatology on outcomes such as mortality, hospitalizations, and quality of life.

    Loss of natural killer cell activity in patients with coronary artery disease2005In: Atherosclerosis, ISSN 0021-9150, E-ISSN 1879-1484, Vol. 183, no 2, p. 316-321Article in journal (Refereed)
    Abstract [en]

    Background:: Natural killer (NK) cells are important components of the innate immune system and have a potential role in the regulation of autoimmunity. In the present study, we evaluated the NK cells in patients with coronary artery disease (CAD) and related the findings to clinical and laboratory parameters of the disease. Methods and results:: We studied 45 patients with acute coronary syndrome (ACS), 50 patients with stable angina and angiographically verified CAD (SA) and 50 healthy controls. The distribution of NK cell subsets was determined by flow cytometry and NK cell-mediated cytotoxicity was quantified ex vivo. Both ACS and SA patients had significantly reduced numbers of CD56dim NK cells compared with controls. The patients also exhibited a significant decrease in NK cell activity. The loss in NK cell function was not related to inflammatory activity or metabolic status. Conclusion:: Both stable and unstable conditions of CAD were associated with a redistribution of circulating lymphocytes, comprising a significant reduction of CD56dim NK cells and a concomitant loss of NK cell function. The findings suggest the presence of a persistent immune aberration in CAD patients independent of their clinical setting or systemic inflammatory state. © 2005 Elsevier Ireland Ltd.

    Chlamydia pneumoniae IgG and the severity of coronary atherosclerosis2004In: European journal of internal medicine, ISSN 0953-6205, E-ISSN 1879-0828, Vol. 15, no 8, p. 508-510Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to compare Chlamydia pneumoniae IgG and the extent of coronary atherosclerosis. We investigated 92 patients with stable angina pectoris who underwent coronary angiography to assess chest pain. Before angiography, C. pneumoniae IgG was analyzed. The number of major coronary arteries (1-3) having at least one diameter narrowing (≥50%) stenosis was determined. The patients were divided into two groups of equal size, according to C. pneumoniae IgG levels. One group included individuals with C. pneumoniae IgG levels exceeding 46 enzyme-immuno-units (EIU)/L and the other consisted of subjects with IgG concentrations below 46 EIU/L. Subjects with higher antibody concentrations had a more severe disease. The number of diseased arteries was 2.1±0.8 (S.D.) and 1.4±0.6 (S.D.) for the two groups, respectively. The difference is highly significant (p<0.0001). This study suggests a causative relationship between C. pneumoniae IgG and the degree of coronary atherosclerosis. It does not, however, prove causality.

    Inverse relationship between platelet density and reactivity alterations at coronary angiography2001In: Haemostasis, ISSN 0301-0147, E-ISSN 1423-0038, Vol. 31, no 1, p. 55-60Article in journal (Refereed)
    Abstract [en]

    This work investigates relationships between platelet density and reactivity. 21 individuals subject to coronary angiography were studied. Peak platelet density was analyzed using a newly developed electronic device. The apparatus measures light transmission through test tubes containing density-separated platelets, thus allowing an estimation of the platelet distribution in the gradient. A flow cytometry technique was used for determining platelet reactivity after stimulating with ADP. Platelet counts, mean platelet volumes, peak platelet density and platelet reactivity were determined immediately before (day 1) and 24 h after cardiac catheterization (day 2). For all parameters changes during the day of angiography were compared with platelet density alterations. The subjects were divided into two groups according to density changes at angiography. Group 1 individuals showed density alterations (i.e. day 2 – day 1 value) ≥–8 × 10–5 kg/l. In contrast, group 2 subjects either displayed density changes <–8 × 10–5 kg/l or grossly disturbed platelet density patterns on day 2. Before angiography both groups had similar platelet counts and volumes. Then platelet reactivity when stimulating with ADP did not differ significantly between the two groups. After angiography, the number of fibrinogen-positive cells when stimulating with ADP rose by 6 ± 8% for group 2 patients. The corresponding figure for group 1 was –1 ± 6%. The difference was significant (p = 0.01). No such relationships were found when comparing density alterations and changes of platelet counts and volumes. We conclude that in this study platelet density alterations at coronary angiography are inversely related to variations of platelet reactivity.

    Individual variations of platelet inhibition after loading doses of clopidogrel2002In: Journal of Internal Medicine, ISSN 0954-6820, E-ISSN 1365-2796, Vol. 252, no 3, p. 233-238Article in journal (Refereed)
    Abstract [en]

    Objective.  To investigate individual variations of platelet inhibition after clopidogrel-loading doses.

    Setting.  Department of Cardiology, Linköping University Hospital, Linköping, Sweden.

    Subjects.  Individuals with stable angina pectoris (n = 18) subject to percutaneous coronary interventions (PCI) and subsequent stenting were investigated.

    Methods and experimental protocol.  A 300-mg clopidogrel loading dose was administrated immediately after stenting (day 1) followed by an additional 75 mg clopidogrel after 24 h (day 2). The ADP-evoked platelet fibrinogen binding was analysed to estimate platelet reactivity immediately before angiography and on day 2. A flow cytometry technique was used with two ADP solutions (final concentrations 0.6 and 1.7 μmol L−1) employed as platelet activating agents. Soluble P-selectin was used as a marker of platelet activity.

    Results.  When using 1.7 μmol L−1 ADP to activate platelets four individuals had a strong inhibition (i.e. platelet reactivity <10% of the day 1-value day 2). In contrast, five patients demonstrated a weak inhibition (i.e. platelet reactivity >60% of the day 1-value day 2). Similar results were obtained when using 0.6 μmol L−1 ADP as a platelet-activating agent. Clopidogrel, however, fails to suppress platelet activity as estimated from soluble P-selectin.

    Conclusions.  Clopidogrel evoked platelet inhibition exhibits a considerable individual heterogeneity. Some individuals only had weak responses whereas others displayed strong platelet inhibition. The present flow cytometry technique appears suitable for identifying patients with abnormal reactions after clopidogrel exposure.

    Elevated platelet reactivity in stable angina pectoris without significant coronary flow obstruction2008In: Journal of Cardiovascular Medicine, ISSN 1558-2027, Vol. 9, no 2, p. 129-130Article in journal (Refereed)
    Abstract [en]

    BACKGROUND:

    There are many different causes of angina pectoris without significant coronary flow obstruction in major coronary arteries. Examples include Prinzmetal angina and small vessel atherosclerotic disease.

    METHODS:

    We investigated individuals with stable angina pectoris subject to elective coronary angiography. To keep the study group as homogeneous as possible, patients with diabetes mellitus were excluded. Subjects with normal coronary angiograms (n = 13) or insignificant (< 50%) coronary flow obstruction(s) (n = 4) were grouped together. The remaining cohort (n = 96) with at least one significant (> or = 50%) flow obstruction in at least one major coronary artery served as controls.

    RESULTS:

    Before angiography, platelet activity in vitro on stimulation with a thrombin-receptor activating peptide (TRAP-6) (57 micromol/l and 74 micromol/l) and ADP (1.7 micromol/l and 8.5 micromol/l) was determined. Angina pectoris individuals without significant flow obstruction in major coronary arteries had enhanced platelet reactivity both when stimulated with TRAP-6 and ADP (P < 0.01 for both TRAP-6 concentrations and P < 0.05 for both ADP concentrations, respectively.

    CONCLUSIONS:

    It is concluded that angina pectoris without significant flow impediment in major epicardial arteries is associated with augmented platelet reactivity.

    A significant relationship between Chlamydia pneumoniae seroreactivity and the severity of coronary atherosclerosisManuscript (preprint) (Other academic)
    Abstract [en]

    Background. Clinical evidence supporting a causal role of Chlamydia pneumoniae in the process of atherosclerosis is limited. It is also uncertain if the organism participates in the inflammatory response in stable angina pectoris. The current study investigates C. pneumoniae IgG and markers reflecting the inflammatory response in stable angina pectoris. The data were subsequently compared with the extent of coronary atherosclerosis.

    Setting. Department of Cardiology, Linköping University Hospital, Linköping, Sweden.

    Experimental protocol. We investigated 92 patients with stable angina pectoris subject to coronary angiography to assess chest pain Before angiography C. pneumoniae IgG, neutrophil count and plasma levels of myeloperoxidase and interleukin 6 were analysed. The number of major coronary arteries (1-3) having at least one diameter narrowing(=> 50%) stenosis was determined. The patients were divided into two equal sized groups according to C. pneumoniae IgG levels.

    Results. Subjects with higher antibody concentrations had a more severe disease. The number of diseased arteries was 2.1±0.8(SD) and 1.4±0.6(SD) for the two groups, respectively. The difference proved to he highly significant (p<0.0001). The groups did not differ with respect to inflammatory parameters.

    Conclusion. This study with 92 consented individuals with stable angina pectoris suggests a causative relationship between C. pneumoniae IgG seroreactivity and the degree of coronary atherosclerosis. It does not, however, prove causality. Thus, it is likely that C. pneumoniae participates in the progression of atherosclerosis.

    Unstable coronary artery disease: non-invasive indicators of severity of coronary lesions and the effects of thrombolysis1994Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Non-invasive indicators of severity of coronary lesions and the effects of thrombolysis were evaluated in 205 men, 38 to 70 years of age with unstable coronary aticty disease (CAD)- i.e. unstable angina or non-Q wave myocardial infarction - admitted to the coronary care units in nine hospitals. The patients were randomised to double-blind and placebo-controlled treatment with an intravenous infusion of recombinant tissue-type plasminogen activator (tt-PA) in addition to aspirin, heparin and betablockade. A symptom-limited exercise test was performed before discharge in 190 patients and a second exercise test, combined with thallium-201 SPECT, was performed after one month in 170 patients. Coronary angiography was performed in 199 patients after one month when also exercise echocardiography and 48 hours ambulatory ST-recording were performed in 65 and 95 patients respectively. The non-invasive tests were compared to each other and to coronary angiography in order to elucidate the best method to identify patients with severe coronary lesions -defined as three vessel disease, left main stenosis or proximal left anterior descending artery stenosis as part of two vessel disease.

    Thrombolytic treatment with rt-PA did not reduce the incidence of death, myocardial infarction or urgent revascularisation early or during one year follow-up. Myocardial ischemia, defined as death, myocardial infarction, revascularisation because of refractory angina or signs of ischemia at an exercise test, was reduced by treatment with rt-PA both at discharge, 53%compared to 70% (p=0.02), and after one month, 61% compared to 80% (p=0.005) respectively. No severe side-effects of rt-PA occurred.

    Stepwise multiple regression analysis showed that ST -depression and low maximal work load were the most important exercise variables for identification of severe coronary lesions. Using a combination of these parameters, the sensitivity and specificity for identification of severe coronary lesions were respectively 77% and 70%. More sophisticated methods of evaluating the ECG reaction during exercise were not diagnostically superior to the simple identification of ST-depression of > 0.1 m V.

    In patients with ST -depression at ambulatory monitoring, 79% demonstrated lhe same finding at the exercise test. A "high risk exercise test response" defined as either ST-depression in:?. 3 leads or ST -depression in 1 - 2 leads with a maximal work load below the 60th percentile or a maximal work load below the 30th percentile regardless of the ECG reaction during exercise, occurred in 82%, while ST -depression at ambulatory monitoring was observed only in 41% of the patients with severe coronary lesions (p<O.OOI).

    A combination of thallium-201 SPECT and ECG at exercise testing identified 82% of the patients with severe coronary lesions with a specificity of 63%. Furthermore, thallium-201 SPECT identified more patients with isolated proximal left anterior descending artery stenosis than the exercise test alone.

    Wall motion abnormalities at exercise echocardiography were seen in 53 patients (81 %) at rest and perfusion defects at thallium-201 SPECT in 57 patients (88%) in the rest images. New or worsening of wall motion abnormalities were seen in 55 patients (180 segments) either seated at peak exercise or recumbent after exercise whereas 43 patients (105 segments) had reversible or partially reversible thallium-201 SPECT scintigraphic defects (p=0.02). The segmental agreement between wall motion abnormalities and scintigraphic defects was low (58%). Theadditional value of exercise echocardiography to the exercise test was greatest in patients with one vessel disease.

    Based on the present and other studies, thrombolysis can not be recommended as a routine therapy in unstable CAD. An early exercise test is safe and contributes to the identification of patients with severe coronary lesions who might benefit from revascularisation. Thallium-201SPECT and exercise echocardiography one month after an episode of unstable CAD have additional value to an ordinary exercise test for the identification or exclusion of severe coronary lesions, while ST -recording has no additional value.

    Risk factors for coronary heart disease in different socioeconomic groups of Lithuania and Sweden - The LiVicordia study2001In: Scandinavian Journal of Public Health, ISSN 1403-4948, E-ISSN 1651-1905, Vol. 29, no 2, p. 140-150Article in journal (Refereed)
    Abstract [en]

    Aims: Lithuanian middle-aged men have a fourfold higher risk for coronary heart disease (CHD) mortality compared with Swedish men. In Sweden, CHD mortality is twice as high in blue- compared with white-collar workers. Whether the same risk factors that characterized Lithuanian men, compared with Swedish men, could be found in low socioeconomic groups within the cities was investigated. Methods: The LiVicordia study compared both traditional and new possible risk factors for CHD among 150 50-year-old men in Link÷ping, Sweden and Vilnius, Lithuania. A comparison was made of the prevalence of these risk factors in high and low socioeconomic groups within the cities and, after controlling for the city, variations across socioeconomic groups in the total sample. Results: Small differences were found in traditional risk factors between cities. However, Vilnius men were shorter, had lower serum levels of antioxidant vitamins, more psychosocial strain, and lower cortisol response to a standardized laboratory stress test. These characteristics were also found among men in low social classes in both cities. In linear regression models, short stature, low serum ▀-carotene, low social integration, coping and self-esteem, high vital exhaustion, high baseline and low cortisol response to stress were related to low social class. Conclusions: The same set of risk factors, mainly relating to oxidative and psychosocial stress, that characterized Vilnius men was also found in men in low social classes within the cities. The results suggest that a common set of risk factors may help to explain health differences both between and within countries. ⌐ Taylor & Francis 2001.

    Ultrasound determined carotid and femoral atherosclerosis in Lithuanian and Swedish men: The LiVicordia study2000In: Atherosclerosis, ISSN 0021-9150, E-ISSN 1879-1484, Vol. 151, no 2, p. 501-508Article in journal (Refereed)
    Abstract [en]

    Coronary heart disease mortality is four times higher in Lithuanian compared to Swedish middle-aged men. Using the same equipment (Acuson XP10 with 5 MHz linear transducer) and staff, we compared the amount of atherosclerosis in carotid and femoral arteries in 100 randomly sampled 50-year-old men in each of the cities Vilnius, Lithuania and Linköping, Sweden. Atherosclerotic plaques were more abundant in Vilnius men compared to Linköping men (53 versus 28% in the common carotid artery, 73 versus 37% in the common femoral artery, P<0.001 for both). Plaques were thicker and more extended in arteries of Vilnius men, and an ultrasound atherosclerosis score was higher in both carotid and femoral arteries (P<0.001 for all). More Vilnius men had a maximal intima-media thickness of the common femoral artery above 1 mm (P<0.005). Stiffness in the common carotid artery was higher in Vilnius men (P<0.001). In a linear regression model of the pooled material, after adjustment for city was made, smoking, systolic blood pressure, low density lipoprotein cholesterol and β-carotene (inversely) significantly contributed to a high total ultrasound score (r2=0.32). These findings show that the higher coronary mortality noted in Lithuanian men goes together with a higher prevalence of early peripheral atherosclerosis.

    Patients operated on for complex congenital heart malformations need continuous follow-up. We present a male patient born in 1948 with Fallot's anomaly. A total correction was performed when he was 21 years old. Twenty-eight years after the operation, at routine follow-up, he presented with a significant left-to-right shunt because of a new ventricular septal defect. During the operation we found the original patch to be fractured with a central perforation. The patient received a new patch and has been without any clinical symptoms since. © 2006 by The Society of Thoracic Surgeons.

    Is early invasive treatment of unstable coronary artery disease equally effective for both women and men?2001In: Journal of the American College of Cardiology, ISSN 0735-1097, E-ISSN 1558-3597, Vol. 38, no 1, p. 41-48Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: The Fragmin and fast Revascularization during InStability in Coronary artery disease (FRISC II) trial compared the effectiveness of an early invasive versus a noninvasive strategy in terms of the incidence of death and myocardial infarction (MI) in patients with unstable coronary artery disease (CAD). OBJECTIVES: In this subanalysis, we sought to evaluate gender differences in the effect of these different strategies. METHODS: The patients (749 women and 1,708 men) were randomized to early invasive or noninvasive strategies. Coronary angiography was performed within the first 7 days in 96% and 10% of the invasive and noninvasive groups, respectively, and revascularization was performed within the first 10 days in 71% and 9% of the invasive and noninvasive groups, respectively. RESULTS: Women presenting with unstable CAD were older, but fewer had previous infarctions, left ventricular dysfunction and elevated troponin T levels. Women had fewer angiographic changes. There was no difference in MI or death at 12 months among women in the invasive and noninvasive groups (12.4% vs. 10.5%, respectively), in contrast to the favorable effect in the invasively treated group of men (9.6% vs. 15.8%, p < 0.001). In an interaction analysis, there was a different effect of the early invasive strategy for the two genders (p = 0.008). CONCLUSIONS: Women with symptoms and/or signs of unstable CAD are older, but still have less severe CAD and a better prognosis compared with men. In contrast to its beneficial effect in men, an early invasive strategy did not reduce the risk of future events among women. Further research is warranted to identify the most appropriate treatment strategy in women with unstable CAD. ⌐ 2001 American College of Cardiology.

    5-year outcomes in the FRISC-II randomised trial of an invasive versus a non-invasive strategy in non-ST-elevation acute coronary syndrome: a follow-up study2006In: The Lancet, ISSN 0140-6736, E-ISSN 1474-547X, Vol. 368, no 9540, p. 998-1004Article in journal (Refereed)
    Abstract [en]

    Background: The FRISC-II invasive trial compared an early invasive with a non-invasive strategy in terms of death and myocardial infarction in non-ST-elevation acute coronary syndrome. We present 5-year follow-up results, overall and in subgroups based on recommended risk stratification criteria. Methods: In the FRISC-II trial, 2457 patients with non-ST-elevation acute coronary syndrome were randomised to early invasive strategy (coronary angiography and, if appropriate, revascularisation, within 7 days from admission) or non-invasive primarily medical strategy. Risk stratification was done on the basis of risk indicators at randomisation: age older than 65 years, male sex, diabetes mellitus, previous myocardial infarction, ST-segment depression, raised troponin concentration (>0·03 μg/L), and raised C-reactive protein or interleukin 6. Information on events after 24 months was taken from national registries. Analyses were done on an intention-to-treat basis. Findings: At 5 years the groups differed in terms of the primary composite endpoint of death, myocardial infarction, or both (invasive 217, 19·9 %, noninvasive 270, 24·5 %, risk ratio 0·81, 95% CI 0·69-0·95, p=0·009). 5-year mortality was 117 (9·7%) in the invasive group compared with 124 (10·1%) in the noninvasive group (0·95, 0·75 -1·21, p=0·693). Rates of myocardial infarction were 141 (12·9 %) in the invasive and 195 (17.7%) in the non-invasive group (0·73, 0·60-0·89, p=0·002). The benefit of the invasive strategy was confined to male patients, non-smokers, and patients with two or more risk indicators. Interpretation: The 5-year outcome of this trial indicates sustained benefit of an early invasive strategy in patients with non-ST-elevation acute coronary syndrome at moderate to high risk. © 2006 Elsevier Ltd.

    Are There Different Effects of Invasive Treatment Between Women and Men During the Acute Stage of Unstable Coronary Artery Disease?Manuscript (preprint) (Other academic)
    Abstract [en]

    OBJECTIVES The FRISC II invasive trial compared an early invasive versus a noninvasive strategy concerning death and MI in CAD. This paper deals with the gender perspective in the same study.

    METHODS There were 749 women and 1708 men included in the study with a mean age of 66 and 64 years in women and men respectively. The patients were randomized to early invasive or noninvasive strategy and to placebo controlled long-term low molecular mass (1mm) heparin ( dalteparin) treatment for 3 months. Coronary angiographies were performed within the first seven days in 96 % and 10 % and revascularisation was performed within the first 10 days in 71 % and 9 % in the invasive and noninvasive groups, respectively.

    RESULTS Women were older but had less previous infarctions, better left ventricular function and less frequently had elevated troponin-levels. There were more patients with normal coronary arteries and less severe coronary artery lesions amongst the women. Accordingly, less interventions were performed in the female group although, among those who were revascularized, there was. no significant difference in the choice of procedure compared to men. There was no difference in the composite endpoint of MI and death at 12 months amongst women (12.4 vs. 10.5% in the invasive and non-invasive groups respectively) in contrast to the very favorable effect of the invasively treated group amongst the men (9.6 vs. 15.8%, p<0.001). In a multivariate interaction analysis there was different effect of early invasive strategy in the two genders (p=0.008)

    CONCLUSIONS Women with symptoms and/or signs of unstable coronary artery disease are older but still have less severe CAD and a better prognosis than men. In contrast to men, an early invasive strategy did not reduce the risk for future events amongst women. Further research is warranted to identify the most appropriate treatment strategy in women with unstable CAD.

    NK cell apoptosis in coronary artery disease. Relation to oxidative stress2008In: Atherosclerosis, ISSN 0021-9150, E-ISSN 1879-1484, Vol. 199, no 1, p. 65-72Article in journal (Refereed)
    Abstract [en]

    Objective: Natural killer (NK) cells, key elements in initiation and modulation of immune responses, were recently found to be reduced in coronary artery disease (CAD). To clarify mechanisms behind this reduction, we here investigated NK cell apoptosis in CAD patients. Since oxidative stress has been linked to NK cell apoptosis, we related the findings to oxidative stress in vivo and evaluated the ex vivo susceptibility of NK cells to oxidized lipids. Methods and results: The number of apoptotic NK cells in peripheral blood was significantly increased in CAD patients compared to controls. Purified NK cells from CAD patients also showed a higher rate of spontaneous apoptosis ex vivo. Dose- and time-dependent effects of oxidized LDL and 7β-hydroxycholesterol (7βOH) on apoptosis and ROS production were determined in NK cells from blood donors. Thereafter, purified NK cells from CAD patients and healthy controls were exposed to the oxidized lipids in a paired design. NK cells from patients were more susceptible to apoptosis induced by oxidized LDL, in particular 7βOH, compared to cells from controls. Plasma measurements of LDL protein oxidation and lipid peroxidation did not show any differences between patients and controls. On the other hand, plasma carotenoids were significantly decreased in patients and inversely correlated to NK cell apoptosis rate. Conclusion: The rate of spontaneous NK cell apoptosis was increased in CAD patients. Although NK cells in CAD patients were more sensitive to oxidized lipids ex vivo, indicating a mechanism contributing to the reduced NK cell activity in CAD, the data could not verify an obvious link between NK cell apoptosis and increased oxidative stress in vivo. © 2007 Elsevier Ireland Ltd.
