Effects of trimetazidine on ischemic left ventricular dysfunction in patients with coronary artery disease

We studied 15 patients with chronic coronary artery disease (13 men aged 62 +/- 8 years) undergoing dobutamine (5 to 40 microg/kg/min) echocardiography at the end of two 15-day treatment periods with placebo and trimetazidine (20 mg 3 times daily) given in random order, according to a double-blind, crossover design. Results show that trimetazidine improves resting left ventricular function and reduces the severity of dobutamine-induced ischemic myocardial dysfunction.
