The effect of trimetazidine on left ventricular systolic function and physical tolerance in patients with ischaemic cardiomyopathy.

Objective: Trimetazidine (TMZ) is the first of novel antianginal drugs with a cardioprotective effect, selectively inhibiting mitochondrial long-chain 3-ketoacyl coenzyme A thiolase. This study tested the hypothesis that the cytoprotective beneficial effect of this agent can lead to the improvement of left ventricular (LV) systolic function and tolerance to physical activity in patients with ischaemic cardiomyopathy.

Methods And Results: In 82 consecutive patients with ischaemic cardiomyopathy, a subgroup of patients (n = 42) was assigned to receive a modified form of TMZ (35 mg twice daily) in addition to the conventional therapy for the duration of three months.
