运动康复治疗对慢性稳定性心力衰竭患者运动耐力、心肺功能及生活质量的影响

Effect of exercise rehabilitation on exercise endurance,cardiopulmonary function and life quality in patients with chronic stable heart failure

目的探讨运动康复治疗对慢性稳定性心力衰竭患者运动耐力、心肺功能及生活质量的影响。方法选取我院收治的慢性稳定性心力衰竭患者80例作为研究对象,随机分为对照组(38例)和观察组(42例)。对照组患者给予常规治疗,观察组患者在常规治疗的基础上进行运动康复治疗。比较两组患者的运动耐力、心肺功能及生活质量改善情况。结果治疗12周后,两组患者的峰值氧耗量(peak VO2)、无氧阈氧耗量(VO2AT)、最大运动功率、最大运动时间、6 min步行距离均显著提高,观察组患者的水平显著高于对照组;两组患者的左房容积指数(LAVI)、明尼苏达心衰生活质量问卷(MLWHFQ)评分均显著降低,左室肌重量指数(LVMI)、左心室射血分数(LVEF)显著增高;观察组患者的LAVI、MLWHFQ评分低于对照组,LVMI、LVEF高于对照组,差异均有统计学意义(P<0.05)。结论运动康复治疗慢性稳定性心力衰竭患者,可明显提高其运动耐力,改善心肺功能,提高生活质量。

Objective To explore the effect of exercise rehabilitation treatment on exercise endurance,cardiopulmonary function and life quality in patients with chronic stable heart failure.Methods A total of 80 patients with chronic stable heart failure admitted to our hospital were selected as the objects,and were randomly divided into control group(38 cases)and observation group(42 cases).The control group received conventional treatment,whereas the observation group underwent exercise rehabilitation on the basis of conventional treatment.The exercise endurance,cardiopulmonary function and the improvement condition of life quality between the two groups were compared.Results After 12 weeks of treatment,peak oxygen consumption(peak VO2),oxygen consumption at anaerobic threshold(VO2 AT),maximum exercise power,maximum exercise time,and 6-minute walking distance were significantly increased in the two groups,and the abovementioned levels were significantly higher in the observation group than in the control group.The left atrial volume index(LAVI)and the Minnesota Living with Heart Failure Questionnaire(MLWHFQ)scores were significantly decreased in both groups,whereas the left ventricular mass index(LVMI)and the left ventricular ejection fraction(LVEF)were significantly increased.The LAVI and MLWHFQ of the observation group were lower than those of the control group,whereas the LVMI and LVEF were higher in the observation group than in the control group,with statistically significant difference(P<0.05).Conclusion Exercise rehabilitation in the treatment of patients with chronic stable heart failure can significantly improve exercise endurance,cardiopulmonary function and life quality.
