Ultrasonic measurements of human carotid and femoral artery walls are conventionally obtained by manually tracing interfaces between tissue layers. The drawbacks of this method are the interobserver variability and inefficiency. In this paper, we present a new automated method which reduces these problems. By applying a multiscale dynamic programming (DP)(More)
AIM To study the efficacy and tolerability of beta-blockade in elderly patients with heart failure in the MERIT-HF study. METHODS AND RESULTS Cox proportional hazards model was used to calculate hazard ratios (HR) with 95% confidence intervals (CI). Risk reduction was defined as (1-HR). In patients > or = 65 years total mortality was reduced by 37% (95%(More)
An operative definition of the metabolic syndrome has been suggested by a working group associated with the World Health Organization in 1998. The aim of this study was to examine whether small, low density lipoprotein (LDL) particle size was associated with the metabolic syndrome and with subclinical atherosclerosis as measured by ultrasound in the carotid(More)
The renal hemodynamic response to subpressor doses of angiotensin II (AII; 0.1 and 0.5 ng/min/kg) was investigated in untreated 49-year-old men (n = 50) representing a wide blood pressure range. Renal blood flow, renal vascular resistance (RVR), glomerular filtration rate (GFR), filtration fraction (FF), plasma renin activity (PRA), plasma AII, plasma(More)
BACKGROUND AND PURPOSE Several cross-sectional and prospective studies have indicated that high titers of antibodies to Chlamydia pneumoniae and cytomegalovirus (CMV) are associated with coronary heart disease. The aim of the present study was to examine whether elevated titers of antibodies to these pathogens are predictive of not only coronary but also(More)
BACKGROUND We examined whether the antiinflammatory action of statins may be of benefit in heart failure, a state characterized by inflammation in which low cholesterol is associated with worse outcomes. METHODS AND RESULTS We compared 10 mg rosuvastatin daily with placebo in patients with ischemic systolic heart failure according to baseline high(More)
B-mode ultrasound is increasingly used in clinical research to study the atherosclerotic process in the carotid arteries. The present investigation evaluated the feasibility of measuring intima-media thickness in the common femoral artery and assessed whether such measurement might provide further information on the extent of the atherosclerotic process in(More)
BACKGROUND Underrepresentation of women in heart failure clinical trials has limited conclusions regarding the effect of various management strategies on survival in women with heart failure and decreased left ventricular ejection fraction (LVEF). METHODS AND RESULTS MERIT-HF (Metoprolol Extended-Release Randomized Intervention Trial in Heart Failure) was(More)
AIMS To investigate whether plasma galectin-3, a mediator of fibrogenesis, can identify patients with chronic heart failure (HF) for whom statins are effective. METHODS AND RESULTS Patients with ischaemic systolic HF enrolled in the Controlled Rosuvastatin Multinational Trial in Heart Failure (CORONA) were randomly assigned to 10 mg/day of rosuvastatin or(More)
AIMS Beta-blockers (BBs) confer significant prognostic benefit in patients (pts) with systolic chronic heart failure (CHF). However, major trials have thus far studied BBs mainly in addition to ACE-Inhibitors or angiotensin receptor blockers (ARBs) as background therapy. The magnitude of the prognostic benefit of BBs in the absence of ACE-I or ARB has not(More)
