目的探讨有氧运动疗法对慢性心力衰竭(chroniccongestiveheartfailure,CHF)患者运动耐力及心功能的影响。方法对48例慢性心力衰竭患者进行心率控制下的有氧运动6个月,并与无运动锻炼的对照组比较其运动耐力及心功能的变化。结果疗程结束后病人的血压、心率有不同程度的下降(P<0.05),运动耐力明显提高(P<0.01),左心功能指数明显改善(P<0.01)。结论有氧运动作为一种中等强度的有氧运动可提高慢性心力衰竭病人的心功能。
Objective To investigate the effects of aerobic exercise on exercise tolerance and cardiac function in patients with chronic heart failure (CHF). Methods Forty-eight patients with chronic heart failure undergoing heart rate-controlled aerobic exercise for 6 months were enrolled in this study. Their exercise tolerance and cardiac function were compared with those of the control group without exercise. Results After the course of treatment, the blood pressure and heart rate of the patients decreased to some extent (P <0.05), the exercise tolerance increased obviously (P <0.01), and the left heart function index improved obviously (P <0.01). Conclusion Aerobic exercise as a moderate-intensity aerobic exercise can improve cardiac function in patients with chronic heart failure.
