[Favorable effect of trimetazidine on clinical state and left ventricular function postinfarction period.]

To assess effect of trimetazidine on clinical course of postinfarction period and restoration of left ventricular myocardium.

1.5-2.0 months after acute myocardial infarctions 123 patients receiving conventional therapy (aspirin, beta-blockers, angiotensin converting enzyme inhibitors, nitrates) were divided into 2 groups. Patients of group 1 (n=62) were given 60 mg/day of trimetazidine and patients of group 2 (n=61) were not. All patients were followed up for 12 months after onset of myocardial infarction.

12 months after myocardial infarction decreases of average heart failure and angina classes, increase of left ventricular ejection fraction, reduction of left ventricular end systolic and end diastolic volumes and left atrial dimensions occurred in group 1. Ejection fraction in this group became significantly higher while left ventricular end systolic and end diastolic volumes and left atrial dimensions significantly lower than in group 2. Index of diastolic function V(e)/V(a)ased in trimetazidine treated patients with normal and hypertrophic types of transmitral diastolic blood flow and became higher than in group 2.

Trimetazidine facilitates restoration of systolic and diastolic left ventricular function after myocardial infarction.
