6分钟步行在慢性心力衰竭患者康复治疗中的价值(英文)

目的:探讨6分钟步行在慢性心衰(CHF)患者康复治疗中的价值。方法:选择我院老年科78例CHF患者,随机分成6min步行试验(6MWT)组(在常规治疗的基础上进行6分钟步行训练,2次/d)和常规治疗组,每组39人。6周后,比较两组治疗前后6min步行距离(6MWD)、心率及左室射血分数(LVEF)。结果:6周后,两组相关指标均有所改善(P均<0.05);与常规治疗组比较,6MWT组6MWD(307.6±39.3)m比(503.4±44.4)m]、LVEF(45.3±17.9)%比(58.7±9.2)%]显著增加,6MWT后恢复期心率(73.3±2.9)次/min比(65.7±2.1)次/min]显著降低(P均<0.05)。结论:6分钟步行可以显著改善患者心力衰竭症状,增强运动耐力,对患者恢复心功能有重要价值。

Value of 6-minute walking in rehabilitation therapy of patients with chronic heart failure

Objective：To explore value of 6-minute walking in rehabilitation therapy of patients with chronic heart failure（CHF）.Methods：A total of 78 CHF patients were selected from department of geriatrics of our hospital.They were randomly and equally divided into 6min walking test（6MWT） group（received 6-min walking training based on routine treatment,twice/d） and routine treatment group.After six weeks,6min walking distance（6MWD）,heart rate and left ventricular ejection fraction（LVEF） were compared between two groups before and after treatment.Results：After six weeks,there were significant improvements in related indexes in both groups,P 0.05 all;compared with routine treatment group,there were significant increase in6MWD （307.6±39.3） m vs.（503.4±44.4） m ] and LVEF （45.3±17.9） %vs.（58.7±19.2） % ],and significant decrease in heart rate of recovery period after 6MWT （73.3±2.9） times/min vs.（65.7±2.1） times/min ] in 6MWT group,P0.05 all.Conclusion：Six-minute walking can significantly improve symptoms of heart failure and enhance exercise tolerance,and it possesses important value for recovery of heart function in these patients.
