Abstract:
Objective The purpose of this study was to examine the effects of exercise training on cardiac function and automatic nervous activity in patients with coronary artery disease(CAD) following PTCA or intracoronary stent implantation. Methods For this study, 37 CAD patients (28 men and 9 women; aged 56.23 ?11.16 years) participated in a supervised 8-week training program with 35 healthy controls(27 men and 8 women; aged 55.72 ?10.34 years). Cardiac function was assessed with indexes obtained during exercise testing using the standard Bruce protocol (submaximal gradural treadmill exercise) before and after 8 weeks training. Meanwhile, heart rate variability (HRV) was used to value the automatic nervous activity. Results After 8 weeks, the margin between maximal HR and resting HR (△HR=HR max-HR resting) was significantly broader (P
