The aim of this prospective randomized study was to evaluate the impact of long-term aerobic exercise training cardiovascular function, left ventricular systolic function and remodeling in patients with coronary heart disease after successful angioplasty.In this quasi-experimental study, 30 patients who had undergone coronary artery angioplasty were enrolled. In the pre-test phase, exercise tolerance test and echocardiography were done for the patients. The aerobic exercise was running on a treadmill to achieve 55% of the maximum heart rate in the first 4 weeks, 60% in the second 4 weeks, and 65% in the last 4 weeks. In each 60-mintute session, 20 minutes was for warming up, 30 minutes for the main exercise, and the last 10 minutes was for cooling down. In the last session, exercise tolerance test and echocardiography were repeated. After 12 weeks of aerobic exercise, the quality of all cardiac function parameters improved. However statistically significant improvement was seen in systolic and diastolic blood pressures during and after the exercise, heart rate, fractional shortening percentage, and duration of the exercise (P<0.001). 12-week aerobic exercise had positive effect on cardiovascular factors in Patients after Angioplasty. Therefore, aerobic exercise is recommended during 12 weeks, 3 sessions per week and for 60 minutes with moderate intensity that lead to improve cardiovascular factors.
