摘　　要：目的探讨运动训练对老年冠心病患者左心室舒张功能的影响。方法 64例老年冠心病患者随机分为运动训练组和常规治疗组,各32例,均接受12周相同的冠心病药物治疗,运动训练组同时进行运动训练。另选择30例健康老年人为正常对照组。超声心动图评估左心室舒张功能和收缩功能,6min步行距离试验评估运动耐量。结果治疗前,与正常对照组相比,其他两组患者左心室舒张晚期二尖瓣峰值血流速度(A)明显增高(P<0.05),左心室舒张早期二尖瓣峰值血流速度(E)、E/A参数明显降低(P<0.05);左心室收缩功能均在正常范围。治疗后,常规治疗组和运动训练组患者E、A、E/A参数均有所改善,6min步行距离均有增加,运动训练组E、A、E/A参数优于常规治疗组(P<0.01);运动训练组较常规治疗组增加更显著(P<0.01);左心室收缩功能无明显改变(P>0.05)。结论运动训练能改善老年冠心病患者的左心室舒张功能和运动耐量。Objective To approach influence of exercise training on left ventricular diastolic function（LVDF）in aged patients with coronary heart disease（CHD）.Methods Sixty four patients with CHD,receiving the same medication,were divided into exercise group（n=32）and non-exercise group（n=32）.The patients in exercise group were given exercise training as following,eg,walking,jogging,up and down stairs,or/and Taiji.Interventional duration was 12 weeks.Another 30 aged volunteers were taken for control.LVDF was evaluated by echocardiogram and exercise tolerance by 6-minute walking distance test（6MWD）.T-test was used statistically.Results There was significantly higher left ventricular A as well as lower left ventricular E and E/A in aged patients with CHD before intervention than those in control（P0.05）.There were striking shorter 6MWDs in aged patients with CHD before intervention than those in control（P0.05）.Left ventricular E,A and E/A were significantly improved in exercise group and non-exercise group after intervention.There were significantly improved left ventricular E,A and E/A in exercise group than those in non-exercise group（P0.05）.6MWDs,which were predominantly increased in exercise group than those in non-exercise group（P0.05）,were significantly increased in both groups than those in control.Left ventricular systolic functions were no difference in all groups before and after intervention.Conclusions Exercise training can improve LVDF and increase exercise tolerance in aged patients with CHD.
