Symptoms of myocardial ischemia ? New ischemic electrocardiographic changes (except for persistent ST-segment elevation in at least two contiguous leads) ? Development of pathological Q waves ? Imaging evidence of new loss of viable myocardium or new regional wall motion abnormality in a pattern consistent with an ischemic etiology

Exclusion criteria

Exclusion criteria: 1) Cardiogenic shock at initial presentation 2) ST-segment elevation myocardial infarction : ST-segment elevation =0.1 mV in at least 2 contiguous leads, or : New onset left bundle branch block : Posterior wall myocardial infarction 3) Refractory angina 4) Life threatening ventricular arrhythmias 5) Life expectancy 90 mmHg, and ?
