- Abstract
Enalapril is effective in the suppression of left ventricular remodeling after acute myocardial infarction (AMI), but the effect of telmisartan is unclear. The consecutive 163 AMI patients underwent primary percutaneous coronary intervention and were randomized to telmisartan ( n = 82) or enalapril ( n = 81). Left ventriculography was performed in the acute and chronic (6 months) phases. Matrix metalloproteinase (MMP)-2 and MMP-9 activities were measured by zymography in the acute (days 1, 7, and 14) and chronic (6 months) phases. Plasma pentraxin3 (PTX3), a marker of vascular inflammation, was also measured. There were no adverse effects in the telmisartan group. The analysis of the left ventriculograms in the acute and chronic phases revealed no difference between the two groups. MMP-9 activities at days 7 and 14 and in the chronic phase were decreased compared to that at day 1 in both groups. MMP-2 activity was also decreased in the acute phase, but increased in the chronic phase in both groups. There was no difference in the plasma PTX3 level in the acute phase, but in the chronic phase, PTX3 was significantly lower in telmisartan than in enalapril group (2.6 ± 1.4 vs. 3.2 ± 1.6 ng/ml, p = 0.04). Telmisartan is well tolerated, shows similar effects on the markers of left ventricular remodeling to those of enalapril, and suppresses vascular inflammation more effectively than enalapril in AMI patients. Telmisartan can be an alternative to angiotensin converting enzyme inhibitor in patients with AMI.
