Raising high-density lipoprotein cholesterol (HDL-C) is an important strategy for reducing residual cardiovascular risk. In the present study, we sought to assess the effect of extended-release niacin/laropiprant on endothelial function in patients after a myocardial infarction with target low-density lipoprotein cholesterol (LDL-C). In this double-blind, placebo-controlled trial, 63 men (35-60 years of age) after a myocardial infarction were randomized to either niacin/laropiprant (1000/20 mg daily for 4 weeks and 2000/40 mg daily thereafter) or placebo.

Background: N-terminal pro-B-type natriuretic peptide (NT-proBNP) is increasingly used in the diagnosis and prognostic assessment of heart failure; however, the possible influence of atrial fibrillation on BNP is still a matter of controversy. We assessed the influence of atrial fibrillation on NT-proBNP levels in outpatients with signs and symptoms of heart failure.

Methods: Consecutive outpatients (n = 306) referred to a university hospital heart-failure clinic for evaluation of signs and symptoms of heart failure underwent clinical and echocardiographic assessment and had their NT-proBNP levels determined in a sandwich chemiluminescent immunoassay with two antibodies on an Elecsys analyzer.

The impact of heart failure with preserved left ventricular ejection fraction (LVEF) on activated hemostasis is still unclear. We sought to compare the activation of hemostasis in patients with heart failure with preserved LVEF, with impaired LVEF, and in healthy controls. Biomarkers of coagulation and fibrinolysis (D-dimer, tPA and PAI-1) were determined in outpatients with chronic stable (NYHA I-III), optimally managed heart failure with preserved LVEF (n = 46) and with impaired LVEF (n = 52), and in healthy age- and gender-matched controls (n = 14).

Heart failure is characterized by activation of the immune system which is strongly associated with disease severity and outcome. We sought to compare the prognostic impact of two established inflammatory markers - interleukin-6 (IL-6) and high-sensitivity C-reactive protein (hsCRP) - in patients with chronic heart failure. In stable, optimally managed outpatients with chronic heart failure, baseline levels of hsCRP and IL-6 were determined.

Advice on lifestyle, diet, vaccination, and therapy are part of the standard management of heart failure (HF). However, there is little information on whether patients with HF recall receiving such recommendations and, if so, whether they report following them. We obtained information on the recall of and adherence to nonpharmacologic advice from patients enrolled in the EuroHeart Failure Survey.

Background: Aspirin has been associated with adverse heart failure outcomes, probably because of a blunting interaction with angiotensin-converting enzyme (ACE) inhibitors. Therefore, we hypothesized that clopidogrel when compared with aspirin would be associated with a slower progression of heart failure as determined by levels of amino-terminal pro-brain natriuretic peptide (NT-proBNP).

Methods And Results: In an open-label, randomized, 2-treatment, 2-period crossover study, 18 patients with ischemic heart failure (14 post-myocardial infarction, left ventricular ejection fraction 0.

Background: The estimation of coronary risk based on consideration of classical risk factors is insufficient in young patients with myocardial infarction who have low expressions of classical risk factors. Endothelial dysfunction (ED) and markers of vascular inflammation may be more appropriate for risk estimation. The relations among ED and inflammation markers in such patients have not yet been explored.

Objective: Androgenic progestins such as norethisterone acetate (NETA) may influence the effect of estradiol (E(2)) therapy. We compared the influence of oral E(2), with and without NETA, and transdermal E(2) on markers of coagulation, fibrinolysis, and inflammation and on lipids and lipoproteins in healthy postmenopausal women.

Design: A total of 112 healthy postmenopausal women were randomized to receive treatment with either oral E(2), with or without NETA, transdermal E(2), or placebo.

Principles: Heart failure is associated with a grim prognosis. Disease management programmes can improve prognosis in heart failure patients but the applicability to the general population remains limited. We aimed to compare the outcome, pharmacological therapy, and quality of life in unselected heart failure patients from a community hospital area who were managed either in the heart failure clinic or who received the usual care.

Background: Endothelial dysfunction and inflammation, in particular their lack of improvement after risk reduction, might better reflect advanced atherosclerosis than just the presence of risk factors. The aim of this study was to compare endothelial function and inflammatory parameters in high-risk patients who had no history of myocardial infarction and in patients in a stable phase after myocardial infarction.

Methods: We compared endothelial function of the brachial artery, measured using high-resolution ultrasound, in 45 patients with hyperlipidaemia (Group 1), and in 45 patients in a stable period after myocardial infarction (Group 2).

Background: Early functional and morphological changes in the course of the atherosclerotic process are manifested as endothelial dysfunction and increased intima-media thickness (IMT) of the arterial wall. These are both associated with various atherosclerotic risk factors. We investigated whether the same factors are associated with functional and morphological changes of the arterial wall in men with combined hyperlipidemia.

The effects of cerivastatin and fenofibrate on proteins involved in haemostasis and on markers of inflammation were investigated in otherwise healthy middle-aged males with combined hyperlipidemia. Besides classical risk factors, other so-called novel risk factors for coronary artery disease are seen to be playing an increasingly important role in the development and progression of atherosclerosis. Thirty-eight males, aged 49 +/-5 years were randomised to 12 weeks treatment either with cerivastatin at a daily dose of 0.
