共选取30例心功能稳定的糖尿病合并慢性心力衰竭患者,将其随机分为2组:训练组(n=15)及常规治疗组(n=15),2组患者均给予内科常规治疗,训练组患者在此基础上同时进行运动训练;并分别在治疗前及治疗8周后对2组患者进行血乳酸、心脏超声及6min步行试验等检查。结果运动训练可以显著降低训练组患者血乳酸水平(P<0.05),增加6min步行距离(P<0.05)。结论运动训练可以显著降低糖尿病并慢性心力衰竭患者血乳酸水平,可能对微循环具有改善作用,并改善其运动功能。 A total of 30 patients with stable cardiac function and chronic heart failure were selected and randomly divided into two groups: training group (n = 15) and conventional treatment group (n = 15). Both groups were given routine medical treatment and training On the basis of this, the patients in the group received exercise training at the same time. And the blood lactate, echocardiography and 6-minute walking test were performed before treatment and 8 weeks after treatment respectively. Results The exercise training significantly reduced the level of blood lactate (P <0.05) and the distance walked 6min (P <0.05). Conclusion Exercise training can significantly reduce blood lactate levels in patients with diabetes mellitus and chronic heart failure, which may improve microcirculation and improve motor function.
