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 survivaland 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

trandolapril

Captopril—most extensively studied with survival benefits in both early initiation and long-term trialsTwo prior direct ARB-ACE-I comparisons to captopril (50 mg tid) showed a trend for fewer deaths and major CV events with captopril therapy.

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

effectivealternative to an ACE inhibitor.
