Aims VALIANT was designed as a mortality trial in high-risk MI patients (SAVE, AIRE, TRACE) who derived particular benefits from an ACE inhibitor. To determine whether: • the ARB valsartan was superior to captopril in improving survival and with equal statistical power • the addition of the ARB valsartan to captopril was superior to the proven dose of captopril in improving survival • If valsartan was not superior to captopril, a non-inferiority analysis was prespecified to determine whether valsartan could be considered “as effective as” captopril

Conclusion In patients with MI complicated by heart failure, left ventricular dysfunction or both: • Valsartan is as effective as a proven dose of captopril in reducing the risk of: • Death • CV death or nonfatal MI or heart failure admission • Combining valsartan with a proven dose of captopril produced no further reduction in mortality—and more adverse drug events. Implications: In these patients, valsartan is a clinically effective alternative to an ACE inhibitor.
