objective trimetazidine has shown anti-ischemic properties to improve exercise tolerance without haemodynamic effects and direct cyto protective effect on the myocardium.however,it is not clear whether trimetazidine has beneficially effect on severe ischemic cardiomyopathy.methods 19patients(68±9)years with postnecrotic left ventricular dysfunction(ejection fraction31.7%±5.4%)were studied to examine the benefit of adding60mg a day of trimetazidine for3months to the classical therapy.the assessment included clinical evaluation,electrocardiography and echocardiography.results after adding60mg a day of trimetazidine for3months,attack of angina was relieved and dyspnea was improved(p.05).but heart rate,systolic blood pressure,rate pressure product,ejection fraction,left ventricular volume and global wall motion index were not changed.conclusion trimetazidine seems to improve clinical status while can not change oxygen supply-to-demand ratio without adverse effects in patients on severe ischemic carˉdiomyopathy.
