- BACKGROUND: The impact of atrial fibrillation (AF) upon platelet reactivity has not been investigated. METHODS: Subjects were 33 individuals with AF who consented to elective electrical cardioversion (ECV) immediately before ECV determination of surface-bound fibrinogen after stimulation i.e. platelet reactivity was carried out. A flow cytometer was employed. ADP (1.7 and 8.5mumol/L) and a thrombin receptor activating peptide (54 and 74mumol/L) were used as agonists. The analyses were repeated after 26+/-8(SD) months. RESULTS: Compared to day 1 subjects with AF (n=18) had a trend towards lower platelet reactivity at study end. It reached significance when using 1.7mumol/L ADP. In contrast, after 26+/-8(SD) months sinus rhythm (SR) (n=15) was associated with significant lower reactivity with all agonists. CONCLUSION: After 26+/-8(SD) months patients returning with AF had higher platelet reactivity than those who remained with SR.

- OBJECTIVES: The aim was to investigate the effects of volume and pressure overload and increased coronary perfusion pressure on coronary flow (CF) in congenital heart disease (CHD) patients. BACKGROUND: The effects of CHD on CF are poorly mapped. METHODS: A total of 65 patients with acyanotic CHD and 49 age-matched healthy controls were examined by transthoracic Doppler echocardiography. Posterior descending artery flow was measured in patients with pulmonary valve stenosis (PS) and atrial septal defects (ASDs) i.e. in lesions with right ventricular pressure or volume overload, and left anterior descending artery flow in patients with coarctation of the aorta (CoA) and ventricular septal defect (VSD), in lesions with left ventricular pressure or volume overload. The CF data in each patient group were expressed as the percent of the median for healthy controls from the same age group. RESULTS: The CF values were in VSD 172%, ASD 185%, PS 233%, and CoA 773% patients. In CoA patients body surface area (r=0.90, p<0.0001), systolic blood pressure (r=0.72, p<0.0001), diastolic blood pressure (r=0.77, p<0.0001), systolic wall tension (r=-0.77, p=0.004), and signs of inflammation (log CRP, r=-0.75, p=0.007) correlated with CF. CONCLUSIONS: The increase in CF and velocity was most significant in patients with CoA. In newborns, increased coronary perfusion pressure seems to be the most important factor for increased CF, even if the pressure is not assumed to cause a significant increase in flow over the auto-regulatory range of 70-130mmHg. We also showed that inflammation decreases CF.

- Aim: Heart failure (HF) is a common but serious condition which involves a significant economic burden on the health care economy. The purpose of this study was to evaluate cost and quality of life (QoL) implications of implementing a HF management program (HFMP) in primary health care (PHC).Methods and results: This was a prospective randomized open-label study including 160 patientswith a diagnosis of HF from five PHC centers in south-eastern Sweden. Patients randomized to the intervention group received information about HF from HF nurses and from a validated computer-based awareness program. HF nurses and physicians followed the patients intensely in order to optimize HF treatment according to current guidelines. The patients in the control group were followed by their regular general practitioner (GP) and received standard treatment according to local management routines. No significant changes were observed in NYHA class and quality-adjusted life years (QALY), implying that functional class and QoL were preserved. However, costs for hospital care (HC) and PHC were reduced by EUR 2167, or 33%. The total cost was EUR 4471 in the intervention group and EUR 6638 in the control group.Conclusions: Introducing HFMP in Swedish PHC in patients with HF entails a significant reduction in resource utilization and costs, and maintains QoL. Based on these results, a broader implementation of HFMP in PHC may be recommended. However, results should be confirmed with extended follow-up to verify long-term effects.

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

- Background: Previous studies of patients with "lone" and "idiopathic" atrial fibrillation (AF) have provided conflicting evidence concerning the development, management and prognosis of this condition. Methods: In this nation-wide, retrospective, cohort study, we studied patients diagnosed with incidental AF recorded in national Swedish registries between 1995 and 2008. Controls were matched for age, sex and calendar year of the diagnosis of AF in patients. All subjects were free of any in-hospital diagnosis from 1987 and until patients were diagnosed with AF and also free of any diagnosis within one year from the time of inclusion. Follow-up continued until 2009. We identified 9519 patients (31% women) and 12,468 matched controls. Results: Relative risks (RR) versus controls for stroke or transient ischemic attack (TIA) in women were 19.6, 4.4, 3.4 and 2.5 in the age categories <55, 55-64, 65-74 and 75-85, years respectively. Corresponding figures for men were 3.4, 2.5, 1.7 and 1.9. RR for heart failure were 6.6, 6.6, 6.3 and 3.8 in women and 7.8, 4.6, 4.9 and 2.9 in men. All RR were statistically significant with p < 0.01. RR for myocardial infarction and all-cause mortality were statistically significantly increased only in the two oldest age categories in women and 65-74 years in men. Conclusions: Patients with AF and no co-morbidities at inclusion had at least a doubled risk of stroke or TIA and a tripled risk of heart failure, through all age categories, as compared to controls. Women were at higher RR of stroke or TIA than men. (C) 2014 The Authors. Published by Elsevier Ireland Ltd.
