Impact of Exercise Rehabilitation on Cardiac Function in Coronary Artery Disease Patients After Percutaneous Coronary Intervention / 中国循环杂志

ABSTRACT

Objective: To explore the impact of exercise rehabilitation on cardiac function in coronary artery disease (CAD) patients after percutaneous coronary intervention (PCI). Methods: A total of 130 CAD patients received primary PCI in our hospital from 2014-01 to 2015-09 were enrolled. All patients received conventional drug therapy and post-PCI knowledge education, then were randomly divided into 2 groups Conventional group and Rehabilitation group, in which the patients received cardiac rehabilitation exercise for 3 months at different stage and intensity. n=65 in each group. The cardiac function including left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), 6 min walking distance (6MWD) and NYHA classification were compared between 2 groups at 1, 3 and 6 months after the operation. Results: LVEF, LVEDD, 6MWD and NYHA classification were similar between 2 groups at enrollment, P>0.05. ① At 1 month post-operation 6MWD was different between 2 groups, P0.05. In Rehabilitation group, 6MWD and NYHA classification were different from the enrollment condition, P0.05; in Conventional group, 6MWD was different from the enrollment condition, P0.05. ② At 3 and 6 months post-operation all parameters were different between 2 groups, P>0.05. In Rehabilitation group, all parameters were different from the enrollment condition, P<0.05. ③ In Conventional group, at 3 months post-operation LVEDD and 6MWD were different from the enrollment condition, P<0.05; at 6 months post-operation 6MWD was different from the enrollment condition, P<0.05. Conclusion: Exercise rehabilitation may improve the cardiac function, therefore enhance the endurance capacity and quality of life in CAD patients after PCI.
