康复运动对慢性心力衰竭患者心功能和运动耐量的影响

The influence of rehabilitation exercise on cardiac function and exercise tolerance of patients with chronic heart failure

目的:探讨康复运动对慢性心力衰竭患者心功能和运动耐量的影响。方法:将37例慢性心力衰竭患者随机分成康复组和对照组,治疗前后以超声心动图和6 min步行试验对两组患者心功能及运动耐量进行评定,康复组在药物治疗的基础上进行康复运动,对照组只进行药物治疗。结果:康复组心功能明显改善(P<0.05),每搏输出量(SV)、左室短轴缩短率(FS)、左室射血分数(LVEF)、6 min步行距离明显增加,运动耐量明显优于对照组(P<0.01)。结论:在常规药物治疗的同时进行康复运动能够更好地改善心力衰竭患者的心功能,提高运动耐量,对心功能恢复有积极意义。

Objective To investigate the influence of rehabilitation exercise on cardiac function and exercise tolerance of patients with chronic heart failure. Methods 37 patients with chronic heart failure were randomly divided into rehabilitation group and control group, be- fore and after treatment, cardiac function and exercise tolerance of the two groups of patients were assessed by echocardiography and 6 mi- nutes walk test. Patients in rehabilitation group received rehabilitation exercise on the basis of medical treatment, while those in control group only received medical treatment. Results Rehabilitation group cardiac function improved significantly （ P 〈 0. 05 ）, Stroke volume （SV）, left ventrieular fraction shortening（FS）, left vemficular ejection fraction （LVEF）, 6 min walking distance, obviously increase, exercise tolerance is better than the control group（ P 〈 0. 01 ）. Conclusion rehabilitation exercise on the basis of medical treatment are better able to improve cardiac function in patients with heart failure,improve exercise tolerance,have positive significance on cardiac function recovery.
