鼓励因素对心力衰竭患者六分钟步行试验的影响

Effect of encouragement on the 6 minute walking test in patients with congestive heart failure

目的:探讨鼓励因素对充血性心力衰竭(congestiveheartfailure,CHF)患者6min步行试验的影响,以指导心力衰竭患者的正确运动。方法:选择CHF患者46例(实验组),健康自愿者22例(对照组),进行6min步行试验,分别采用不鼓励和鼓励的方法,运动后测量步行的距离。结果:实验组与对照组不鼓励和鼓励6min步行距离分别为(346.15±66.83)和(389.24±71.53)m,(505.41±63.13)和(551.82±62.79)m,差异有显著性意义(P<0.01);心功能Ⅱ级患者较心功能Ⅲ级患者步行距离更远,不鼓励与鼓励也差异有显著性意义(P<0.01);CHF患者心功能与6min步行距离呈正相关。结论:鼓励因素可增加CHF患者6min步行距离,6min步行试验可评价心功能情况,提高患者生活质量。

AIM:To explore the influence of encouragement on the 6 minute walking test in patients with congestive heart failure(CHF),so as to guide their correct exercise. METHODS:Totally 46 CHF patients(study group) and 22 healthy volunteers(control group) participated in the 6 minute walking test.The walking distances after exercise were measured.RESULTS:The walking distances before and after encouragement in the study group[(346.15±66.83) m and(389.24±71.53) m] were significantly different from those in the control group[(505.41±63.13) m and(551.82 ±62.79) m](P< 0.01).Patients with grade Ⅱcardiac function could walk farther than those with grade Ⅲcardiac function,and there was also significant difference before and after encouragement(P< 0.01).There was positive correlation between the cardiac function and 6 minute walking distance.CONCLUSION:Encouragement increases the 6 minute walking distance of CHF patients.The 6 minute walking test can evaluate the cardiac function and improve the quality of life in the CHF patients.
