- OBJECTIVES: To compare the effects of the beta-blocker atenolol with the angiotensin receptor blocker (ARB) losartan on plasma tissue-type plasminogen activator (tPA) activity and mass concentration, plasminogen activator inhibitor-1 (PAI-1) activity, tPA/PAI-1 complex, and von Willebrand factor (VWF). DESIGN: A prespecified, explorative substudy in 22 patients with hypertension and left ventricular hypertrophy (LVH) performed within randomized multicenter, double-blind prospective study. RESULTS: After a median of 36 weeks of treatment, there were significant differences between the treatment groups, atenolol versus losartan, in plasma median levels of tPA mass (11.9 vs 7.3 ng/mL, P = .019), PAI-1 activity (20.7 vs 4.8 IU/mL, P = .030), and tPA/PAI-1 complex (7.1 vs 2.5 ng/mL, P = .015). In patients treated with atenolol, median levels of tPA mass (8.9-11.9 ng/mL, P = .021) and VWF (113.5%-134.3%, P = .021) increased significantly, indicating a change toward a more prothrombotic state. No significant changes occurred in the losartan group. CONCLUSION: Losartan treatment was associated with preserved fibrinolytic balance compared to a more prothrombotic fibrinolytic and hemostatic state in the atenolol group. These findings suggest different fibrinolytic and hemostatic responses to treatment in hypertensive patients with LVH.

- BACKGROUND AND PURPOSE: C-reactive protein (CRP) is a determinant of stroke, but there are no prospective studies on CRP and first ischemic stroke divided into etiologic subtypes. Our primary aim was to study CRP as a determinant of ischemic stroke, classified according to Trial of ORG 10172 in Acute Stroke Treatment (TOAST) criteria, and intracerebral hemorrhage (ICH) in a prospective study. A secondary aim was to study the relationship between the 1444C>T polymorphism, plasma levels of CRP and stroke. METHODS: The study was a prospective population-based case-referent study nested within the Northern Sweden Cohorts. We defined 308 cases of ischemic stroke and 61 ICH. Two controls for each case were defined from the same cohort. RESULTS: The OR for the highest (>3 mg/l) versus lowest group (<1 mg/l) of CRP was 2.58 (95% CI 1.74-3.84) for ischemic stroke and 1.63 (95% CI 0.67-3.93) for ICH. In a multivariate model including traditional risk factors, CRP remained associated with ischemic stroke (OR 2.06; 95% CI 1.29-3.29). Small-vessel disease was associated with CRP in the multivariate model (OR 3.88; 95% CI 1.10-13.7). The CRP 1444 (CC/CT vs. TT) polymorphism was associated with plasma levels of CRP but neither with ischemic stroke nor with ICH. CONCLUSIONS: This prospective population-based study shows that CRP is significantly associated with the risk of having a first ischemic stroke, especially for small-vessel disease. No significant associations were found between the CRP 1444C>T polymorphism and any stroke subtype.

- OBJECTIVE: In Sweden, previous favourable trends in blood cholesterol levels have recently levelled off or even increased in some age groups since 2003, potentially reflecting changing fashions and attitudes towards dietary saturated fatty acids (SFA). We aimed to examine the potential effect of different SFA intake on future coronary heart disease (CHD) mortality in 2025. METHODS: We compared the effect on future CHD mortality of two different scenarios for fat intake a) daily SFA intake decreasing to 10 energy percent (E%), and b) daily SFA intake rising to 20 E%. We assumed that there would be moderate improvements in smoking (5%), salt intake (1g/day) and physical inactivity (5% decrease) to continue recent, positive trends. RESULTS: In the baseline scenario which assumed that recent mortality declines continue, approximately 5,975 CHD deaths might occur in year 2025. Anticipated improvements in smoking, dietary salt intake and physical activity, would result in some 380 (-6.4%) fewer deaths (235 in men and 145 in women). In combination with a mean SFA daily intake of 10 E%, a total of 810 (-14%) fewer deaths would occur in 2025 (535 in men and 275 in women). If the overall consumption of SFA rose to 20 E%, the expected mortality decline would be wiped out and approximately 20 (0.3%) additional deaths might occur. CONCLUSION: CHD mortality may increase as a result of unfavourable trends in diets rich in saturated fats resulting in increases in blood cholesterol levels. These could cancel out the favourable trends in salt intake, smoking and physical activity.

- BACKGROUND: Exercise lowers blood pressure and improves cardiovascular function, but little is known about whether exercise impacts cardiovascular morbidity and mortality independent of left ventricular hypertrophy (LVH) and LV geometry. DESIGN: Observational analysis of prospectively obtained echocardiographic data within the context of a randomized trial of antihypertensive treatment. METHODS: A total of 937 hypertensive patients with ECG LVH were studied by echocardiography in the Losartan Intervention For Endpoint reduction in hypertension study. Baseline exercise status was categorized as sedentary (never exercise), intermediate (30 min twice/week). During 4.8-year follow-up, 105 patients suffered the primary composite endpoint of myocardial infarction (MI), stroke, or cardiovascular death. MI occurred in 39, stroke in 60, and cardiovascular death in 33 patients. RESULTS: Sedentary individuals (n = 212) had, compared with those physically active (n = 511), higher heart rate (P<0.001), weight (P<0.001), body surface area (P = 0.02), body mass index (P<0.001), LV mass (LVM, P = 0.04), LVM indexed for height or body surface area (P = 0.004); thicker ventricular septum (P = 0.012) and posterior wall (P = 0.016); and larger left atrium (P = 0.006). Systolic variables did not differ. In Cox regression analysis, physically active compared with sedentary patients had lower risk of primary composite endpoint [odds ratio (OR): 0.42, 95% confidence interval (CI): 0.26-0.68, P < 0.001], cardiovascular death (OR: 0.50, 95% CI: 0.22-0.1.10, NS), and stroke (OR: 0.26, 95% CI: 0.13-0.49, P < 0.001) without significant difference for MI (OR: 0.79, 95% CI: 0.35-1.75, NS) independent of systolic blood pressure, LVM index, or treatment. CONCLUSION: In hypertensive patients with LVH, physically active patients had improved prognosis for cardiovascular endpoints, mortality, and stroke that was independent of LVM.

- Within previous research on family care of terminally ill people, studies have only rarely been carried out concerning heart failure care. This study aims to illuminate meanings of being a close relative of a person with severe, chronic heart failure (CHF) in palliative advanced home care (PAHC). Narrative interviews were conducted with three close relatives, tape-recorded, transcribed verbatim and a phenomenological-hermeneutic method was used to interpret the text. Meanings of being a close relative is to follow the life-threatening ups and downs, the person with CHF is going through. This means being on primary call, always on standby to mediate security and pleasure. In the deepest downs it is also to call for the back-up call i.e. the PAHC team, trusting their ability to show up on time to alleviate in the worst downs i.e. ease suffering. This study reveals that to be the close relative that the ill person is dependent on 24 hours a day is both a comfort and a strain.

- BACKGROUND: Living with severe chronic heart failure (CHF) in palliative care has been little studied. AIM: The aim of this study is to illuminate meaning of living with severe CHF in palliative advanced home care through patients' narratives. METHODS: Narrative interviews were conducted with 4 patients, tape-recorded and transcribed verbatim. A phenomenological-hermeneutic method was used to interpret the text. RESULTS: Meaning of living with severe CHF in palliative advanced home care emerged as 'knocking on death's door' although surviving. The course of the illness forces one to live a 'roller coaster life,' with an ongoing oscillation between ups and downs. Making it through the downs breeds a kind of confidence in one's ability to survive and the will to live is strong. Being offered a safety belt in the 'roller coaster' by the palliative advanced home care team evokes feelings of security. CONCLUSIONS: Meaning of living with severe CHF in palliative advanced home care is on one hand, being aware of one's imminent death, on the other hand, making it through the downs i.e. surviving life-threatening conditions, breed confidence in also surviving the current down. Being constructively dependent on palliative advanced home care facilitates everyday life at home.

- The early mitral flow deceleration time (DTE) is a prognostically validated marker of left ventricular diastolic dysfunction. It has been reported that the DTE is influenced by the loading conditions, which can vary during antihypertensive treatment. We hypothesized that normalization of the DTE for mitral peak E-velocity (mitral deceleration index [MDI]) might better predict incident cardiovascular (CV) events in hypertensive patients during treatment compared to DTE alone or other traditional indexes of diastolic function, such as the mitral E/A ratio. We evaluated 770 hypertensive patients with electrocardiogram findings of left ventricular hypertrophy (age 66 +/- 7 years; 42% women) enrolled in the Losartan Intervention For Endpoint reduction in hypertension (LIFE) echocardiographic substudy. Echocardiographic examinations were performed annually for 5 years during intensive antihypertensive treatment. We examined the utility of the MDI at baseline and as a time-varying predictor of incident CV events. Of the 770 patients, 70 (9%) had CV events. The baseline MDI was positively associated with age and relative wall thickness and negatively associated with gender and heart rate (all p <0.01). Unadjusted Cox regression analysis showed a positive association between the baseline MDI and CV events (hazard ratio 1.21, 95% confidence interval 1.07 to 1.37, p = 0.002). In the time-varied Cox models, a greater in-treatment MDI was associated with a greater rate of CV events (hazard ratio 1.43, 95% confidence interval 1.05 to 1.93, p = 0.022), independently of the covariates. No significant association was found for in-treatment DTE or any of the prognostically validated indexes of diastolic function. In conclusion, in our population of patients with treated hypertension with electrocardiographic findings of left ventricular hypertrophy, the MDI independently predicted future CV events. Normalization of DTE for E velocity might be preferred to other traditional diastolic function indexes in evaluating diastolic function during antihypertensive treatment.

- OBJECTIVES: Left ventricular systolic wall motion abnormalities have prognostic value. Whether wall motion detected by serial echocardiographic examinations predicts prognosis in hypertensive patients with left ventricular hypertrophy (LVH) without clinically recognized atherosclerotic disease has, however, never been investigated. We examined whether 'in-treatment' wall motion abnormalities predicted outcome in the Losartan Intervention For Endpoint (LIFE) reduction in hypertension echocardiographic substudy.METHODS: We studied 749 patients without coronary artery disease, myocardial infarction (MI), or stroke history. Echocardiographic segmental wall motion abnormalities at baseline and annual re-evaluations ('as time-varying covariate') were examined in relation to endpoints (cardiovascular mortality, MI, stroke, and hospitalized heart failure). Adjusted Cox regression was used to analyze the primary composite endpoint of cardiovascular death, MI, or stroke and, separately, for fatal and nonfatal MI and hospitalized heart failure.RESULTS: During a mean follow-up of 4.8 years, an event was recorded in 67 (9%) patients. In Cox models after adjusting for age, gender, treatment, blood pressure lowering, and serial change of left ventricular mass index, 'in-treatment' segmental wall motion abnormalities were associated with subsequent composite endpoint [hazard ratio = 2.1, 95% confidence interval (CI) 1.1-3.8; P = 0.019] and MI [hazard ratio = 3.7 (1.5-8.9); P = 0.004].CONCLUSION: In hypertensive patients with LVH and no history of cardiovascular disease, 'in-treatment' left ventricular wall motion abnormalities are associated with increased likelihood of subsequent cardiovascular events independent of age, gender, blood pressure lowering, treatment modality, and in-treatment left ventricular mass index.
