有氧运动对2型糖尿病心力衰竭患者心功能的影响

Effect of Aerobic Exercise on the Cardiac Function of Patients with Type 2 Diabetes Mellitus Complicated with Heart Failure

目的探讨有氧运动对2型糖尿病心力衰竭患者心功能及血糖的影响。方法选择50例心功能Ⅱ级或Ⅲ级的2型糖尿病心力衰竭患者,随机分为对照组(单纯药物治疗)和观察组(有氧运动联合药物治疗)各25例。评估患者治疗前和治疗12周后的血糖情况、6 min步行试验距离,以及心彩超左室舒张末期内径(LVEDD)、射血分数(EF)。结果治疗12周后,观察组的空腹血糖(FPG)、餐后2 h血糖(2h PG)、LVEDD值均显著低于对照组,EF值、6 min步行试验距离均显著高于对照组,差异具有统计学意义(P<0.05)。结论 2型糖尿病心力衰竭患者进行有氧运动可有效提高心功能。

Objective To explore the effect of aerobic exercise on the cardiac function and blood glucose of patients with type 2 diabetes mellitus complicated with heart failure. Methods 50 cases of patients with type 2 diabetes mellitus complicated with heart failure were selected and randomly divided into two groups, with 25 cases in each group. The control group received drug treatment only, while the observation group received aerobic exercise combined with drug treatment. Before treatment and after 12 weeks＇ treatment, the blood glucose, 6 minutes walking test （6MWT） distance, and left ventricular end diastolic diameter （LVEDD） and ejection fraction （EF） detected by ultrasonic cardiogram of both groups were evaluated. Results After 12 weeks＇ treatment, the levels of fasting plasma glucose （FPG） and 2 h postprandial blood glucose （2hPG）, and LVEDD value of observation group were significantly lower than those of control group, and the EF value and 6MWT distance were significantly higher than those of control group （all P 〈0.05）. Conclusions Aerobic exercise can effectively improve the cardiac function of patients with type 2 diabetes mellitus complicated with heart failure.
