The effect of trimetazidine on reperfusion arrhythmias in acute myocardial infarction.

The study aims to evaluate the effect of trimetazidine in reducing reperfusion arrhythmias in patients with acute myocardial infarction after successful thrombolysis. A total of 169 patients were included in the study, 83 of whom received trimetazidine orally at an initial dose of 60 mg followed by 20 mg tid for 5 days. These patients formed the study group (group T) while the remaining 86, the control group (group C).

Comparison of Q with non-Q myocardial infarction using signal averaged ECG.

Forty consecutive patients (pts) with acute myocardial infarction (MI) who survived to be discharged from the hospital were studied with high gain signal averaged electrocardiography (SAECG). 28% of the pts with non-Q MI had an abnormal SAECG as compared to 15% in the Q MI group. It was also found that SAECG showed a significantly longer filtering QRS duration in the non-Q MI group.
