Inhibitory effect of valsartan against progression of left ventricular dysfunction after myocardial infarction: T-VENTURE study.
BACKGROUND
Angiotensin-converting enzyme inhibitors (ACEI) reduce the mortality in the chronic phase of myocardial infarction (MI), and similar effects of angiotensin receptor blockers (ARB) have been reported. However, these effects of ARB have not yet been established in Japanese patients. A multicenter randomized study was designed for the present study to examine the effect of valsartan as compared to that of ACEI against left ventricular dysfunction after MI.


RESULTS
Patients with acute MI were randomly allocated to either the valsartan group (n=120; mean age 63 +/-1.0) or the ACEI group (n=121; mean age 62.9 +/-1.0) and followed up until 6 months. Left ventriculography was performed during hospital admission and at 6 months. The blood pressure was similar in the 2 groups throughout the study. The incidences of cardiovascular events and target vessel revascularization were similar, although that of adverse events was significantly higher in the ACEI (12.4%) than in the valsartan group (3.3%; P<0.05). There were no differences in left ventricular ejection fraction and left ventricular end-diastolic volume index between the groups.


CONCLUSIONS
Valsartan exhibits similar efficacy effective to that of ACEI in preventing left ventricular dysfunction in Japanese patients with acute MI, and is, in addition, better tolerated than ACEI.
