ABSTRACT
The number of patients with newly diagnosed heart failure continues to grow worldwide, to some extent reflecting the increase in survival after acute coronary syndromes and the aging of the population. The search for new and effective therapies for this condition remains a priority in the 21st century. The use of beta-blockers is now well established in the clinical context of mild and moderate systolic heart failure. The effects of beta-blockade on mortality are additive to those with angiotensin-converting enzyme inhibitor therapy. Recently completed, large, randomized trials provided strong evidence for the use of beta-blockers in severe (NYHA functional class IV) heart failure and in asymptomatic patients with left ventricular systolic dysfunction and recent myocardial infarction. Obviously, patient selection still remains the key to the safe use of beta-blockers in patients with heart failure. Further data from clinical trials have emerged to support similar benefits in terms of mortality and morbidity, a good safety record, and tolerability in patients at extremes of age (children and adults >70 years of age) and in specific clinical circumstances (including diabetes, chronic obstructive airways disease, renal failure, and atrial fibrillation). Recent use of beta-blockers with vasodilatory properties in patients with heart failure and preserved systolic function (so-called diastolic heart failure) appears promising but will require large-scale, long-term trials prior to widespread clinical use.
