Dr. Pfeffer is named as a coinventor on a patent
awarded to the Brigham and Womens 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 Womens Hospital, which is not
linked to sales.
Supported by a grant from Novartis Pharmaceuticals

ACE InhibitorMI Mortality Trials
  • Selective(higher risk, long term)
  • SAVE (EF 40)
  • AIRE (clinical HF)
  • SMILE (anterior MI, no lytic)
  • TRACE (wall motion score, EF 35)
  • Broad (short term)
  • CONSENSUS II
  • GISSI-3

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

7
ACE-I Comparator MI Trial
  • MI Trials with Mortality Benefit
  • Early Use Long-Term
  • GISSI 3 lisinopril SAVE captopril
  • ISIS 4 captopril AIRE ramipril
  • Chinese-Cap captopril TRACE trandolapril
  • Captoprilmost extensively studied with survival
    benefits in both early initiation and long-term
    trials

Two 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
    mortalityand more adverse drug events.
  • Implications
  • In these patients, valsartan is a clinically
    effective
  • alternative to an ACE inhibitor.
