Effect of aerobic exercise on exercise tolerance in patients with chronic heart failure

目的探讨有氧运动对慢性心力衰竭患者运动耐量的影响。方法选取68例老年慢性心力衰竭患者,随机分为运动训练组和常规药物治疗组,运动训练组在接受相同药物治疗的同时给予有氧运动训练,用6 min步行试验评估运动耐量。结果运动训练组和常规药物治疗组6 min步行距离均较治疗前延长,运动训练组较常规药物治疗组延长更明显,差异有统计学意义(P<0.05)。结论有氧运动有助于提高慢性心力衰竭患者的运动耐量。

Objective To investigate the effect of aerobic exercise on exercise tolerance in patients with chronic heart failure.Methods Sixty-eight elderly patients with chronic heart failure were randomly divided into exercise training group and routine medications treatment group,receiving the same medications treatment. The exercise training group was given additional aerobic exercise training at the same time. The exercise tolerance was assessed with 6-minute walk test. Results Compared with pretreatment baseline,the 6-minute walk distance of each group was longer. The 6-minute walk distance of exercise training group was more prolonged than that of the routine medications treatment group,with significant difference（P〈0.05）. Conclusion Aerobic exercise can improve exercise tolerance in patients with chronic heart failure.
