A Study of Valsartan Administered Once Daily Versus Twice Daily, in Patients With Stable, Chronic Heart Failure

This study will evaluate the tolerability and safety of valsartan in patients with stable, chronic heart failure (NYHA Class ll-lll). The 12-week double blind study has a 2-week (maximum) screening, and a 10-week active treatment phase. In each of the treatment arms (QD and BID), patients are up-titrated to a maximum valsartan total daily dose of 320 mg. Patients remain on their prior CHF standard care therapy throughout the study period, and the up-titration of valsartan is based on patient tolerability.
