Transcript of Supported by a grant from Novartis Pharmaceuticals
Dr. Pfeffer is named as a coinventor on a patent awarded to the Brigham and Women’s Hospital regarding the use of inhibitors of the renin-angiotensin system in selected survivors of myocardial infarction; there is a
licensing agreement between Novartis Pharmaceuticals and the Brigham and Women’s Hospital, which is not linked to sales.

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

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.
