BACKGROUND: To investigate the role of persistent angiotensin activity despite angiotensin-converting enzyme inhibitor therapy in the progression of heart failure, the ValsartanHeart Failure Trial has been designed to investigate the effect of the angiotensin-receptor blocker, valsartan, on morbidity and mortality. METHODS AND RESULTS: Nearly 5,000 patients with New York Heart Association classes II to IV heart failure, while receiving all standard therapy, are being randomized to treatment with valsartan, 160 mg twice daily, or placebo in a worldwide study. Follow-up will be continued until 906 deaths have been recorded. Additional end points will include the need for hospitalization, other major morbid events, quality--of life measurement, changes in neurohormone levels, and changes in left ventricular size and function. Substudies will explore exercise tolerance, arrhythmias, and magnetic resonance imaging. CONCLUSION: This study should help establish the role of angiotensin-receptor blockade in the treatment of heart failure.
