Initiating rehabilitative exercise training within two weeks of an acute myocardial infarction is beneficial for patients with residual myocardial ischemia after heart attack and angioplasty, according to findings presented at a cardiology meeting. Patients who did exercise training showed an average 29% rise in peak exercise capacity and a 10% average rise in peak heart rate after six months, the study said. SPECT findings revealed that left ventricular ejection fraction increased from a baseline average of 48% to 52% with rehabilitation. SPECT scans also showed that myocardial perfusion defect and ischemia were reduced by 50% in patients who exercised.
