运动康复干预对改善慢性心力衰竭患者心脏功能的效果研究

Study on the effect of exercise rehabilitation intervention on improving the cardiac function of patients with chronic heart failure

目的分析予以慢性心力衰竭(CHF)患者运动康复干预对其心脏功能的影响。方法80例CHF患者,依据随机数字表法分为对照组及观察组,每组40例。对照组予以常规干预措施,观察组在对照组基础上加以运动康复干预。比较两组干预前后的左室射血分数(LVEF)、左室收缩末期内径(LVESD)、左室舒张末期内径(LVEDD)、心率水平以及6 min步行试验(6MWT)情况。结果干预后,观察组LVEF(46.14±6.62)%高于对照组的(38.72±5.94)%,LVESD(38.70±5.32)mm以及LVEDD(50.25±6.32)mm小于对照组的(44.20±6.05)、(56.20±5.68)mm,差异有统计学意义(P<0.05)。干预后,观察组6MWT(196.96±32.45)m长于对照组的(114.20±29.86)m,心率(76.14±6.35)次/min低于对照组的(88.96±6.94)次/min,差异有统计学意义(P<0.05)。结论予以CHF患者运动康复干预能改善其心功能,提升其6 min步行距离,降低其心率水平,值得采用。

Objective To analyze the effect of exercise rehabilitation intervention on improving the cardiac function of patients with chronic heart failure(CHF).Methods A total of 80 CHF patients were divided into control group and observation group according to the random numerical table,with 40 cases in each group.The control group received conventional intervention measures,and the observation group received exercise rehabilitation intervention on the basis of the control group.Both groups were compared in terms of left ventricular ejection fraction(LVEF),left ventricular end systolic diameter(LVESD),left ventricular end diastolic diameter(LVEDD),heart rate,and 6-min walk test(6MWT)before and after the intervention.Results After the intervention,the LVEF(46.14±6.62)%of the observation group was higher than(38.72±5.94)%of the control group,and the LVESD(38.70±5.32)mm and LVEDD(50.25±6.32)mm of the observation group were less than(44.20±6.05)and(56.20±5.68)mm of the control group;all the differences were statistically significant(P<0.05).After the intervention,the 6MWT(196.96±32.45)m of the observation group was longer than(114.20±29.86)m of the control group,and the heart rate(76.14±6.35)beats/min was lower than(88.96±6.94)beats/min of the control group.All the differences were statistically significant(P<0.05).Conclusion Exercise rehabilitation intervention for CHF patients can improve their cardiac function,increase their 6-min walk distance,and reduce their heart rate levels,which is worthy of application.
