Chronic heart failure (CHF) is a leading cause of morbidity and mortality. Although a precise definition for a cut-off value of hemoglobin level for anemia is still lacking, it has recently been found to be a common complication in CHF, occurring in 10-20% of patients. There are several possible pathogenetic ...

In heart failure patients, diuretics cause renin-angiotensin-aldosterone system (RAS) activation, which may lead to increased morbidity and mortality despite short-term symptomatic improvement. To determine changes in RAS activation and clinical correlates following furosemide withdrawal in elderly heart failure patients without left ventricular systolic dysfunction. We performed clinical assessments and laboratory ...

Blood concentrations of angiotensin II are often raised in patients with heart failure, despite treatment with angiotensin-converting-enzyme (ACE) inhibitors. We compared concentrations of angiotensin II in two groups of matched patients, receiving ACE inhibitor therapy with or without concomitant administration of beta-blockers. Concentrations of angiotensin II were lower in individuals ...
