Candesartan in heart failure—assessment of reduction in mortality and morbidity (CHARM): Rationale and design

BACKGROUND: Chronic heart failure (CHF) is an increasing burden to health care. Pharmacological treatment with angiotensin-converting enzyme (ACE) inhibitors and beta blockers improve survival and reduce hospitalizations in patients with low left ventricular ejection fraction (LVEF).
