基于心肺运动试验评估的运动康复治疗对慢性心力衰竭患者心功能及运动耐力的影响

Effects of Exercise Rehabilitation Therapy Based on Cardiopulmonary Exercise Test on Cardiac Function and Exercise Tolerance in Patients with Chronic Heart Failure

目的探讨基于心肺运动试验评估的运动康复在慢性心力衰竭(chronic heart failure,CHF)患者中的价值.方法选取2019年12月—2020年12月该院收治的92例CHF患者,按随机数字表法分为两组,各46例.对照组采用常规运动干预,观察组加用基于心肺运动试验评估的运动康复训练,连续干预3个月.对比两组心功能、运动耐力、生活质量.结果干预前,两组左心室射血分数(left ventricular ejection fraction,LVEF)、左心室收缩末期内径(left ventricular end systolic diameter,LVESD)、左心室舒张末期内径(left ventricular end-diastolic dimension,LVEDD)、6 min步行试验(6 min walk test,6MWT)、生活质量调查问卷(quality of life-30,QOL-30)评分相比,差异无统计学意义(P>0.05);干预后,观察组LVEF、QOL-30评分高于对照组,LVESD、LVEDD低于对照组,6MWT长于对照组,组间差异有统计学意义(P<0.05).结论基于心肺运动试验评估的运动康复训练能够有效改善CHF患者的心功能,提高其运动耐力及生活质量,值得应用.

Objective To explore the value of exercise rehabilitation based on cardiopulmonary exercise test in patients with chronic heart failure(CHF).Methods 92 patients with CHF treated in the hospital from December 2019 to December 2020 were randomly divided into two groups,46 cases in each group.The control group was given routine exercise intervention,and the observation group was added with exercise rehabilitation training based on cardiopulmonary exercise test evaluation for 3 months.Cardiac function,exercise endurance and quality of life were compared between the two groups.Results Before intervention,there was no significant difference in left ventricular ejection fraction(LVEF),left ventricular end systolic diameter(LVESD),left ventricular end diastolic diameter(LVEDd),6 min walk test(6MWT)distance and quality of life-30(QOL-30)between the two groups(P>0.05);After the intervention,the of LVEF and QOL-30 scores in the observation group were higher than those in the control group,LVESD and LVEDD were lower than those in the control group,and the distance of 6MWT was longer than that in the control group(P<0.05).Conclusion Exercise rehabilitation based on cardiopulmonary exercise test can effectively improve the cardiac function,exercise endurance and quality of life of patients with CHF.
