体外反搏治疗射血分数保留型与射血分数降低型心力衰竭患者的效果比较

Comparison of effects of external counterpulsation in treatment of heart failure patients of preserved ejection fraction type and reduced ejection fraction type

目的:比较体外反搏治疗射血分数保留型与射血分数降低型心力衰竭患者的效果。方法:选取2019年6月至2021年4月该院收治的108例心力衰竭患者进行前瞻性研究,均进行射血分数检测,根据其射血分数水平,将54例射血分数保留型心力衰竭患者纳入对照组,将54例射血分数降低型心力衰竭患者纳入观察组,两组均在常规对症治疗基础上接受体外反搏治疗,比较两组治疗前后心功能指标[左心室射血分数(LVEF)、左心室舒张末期内径(LVEDD)和左心房内径(LAD)]水平、运动耐量[6 min步行距离(6MWD)]、睡眠质量[匹兹堡睡眠质量指数(PSQI)]评分、生命质量[明尼苏达心衰生活质量调查表(LiHFe)]评分和再入院率。结果:治疗后,两组LVEF水平均高于治疗前,LVEDD和LAD水平均低于治疗前,但组间比较,差异无统计学意义(P>0.05);治疗后,两组6MWD均长于治疗前,但组间比较,差异无统计学意义(P>0.05);两组PSQI和LiHFe评分均低于治疗前,但组间比较,差异无统计学意义(P>0.05);随访12个月,两组再入院率比较,差异无统计学意义(P>0.05)。结论:体外反搏治疗射血分数保留型和射血分数降低型心力衰竭患者的效果相当。

Objective:To compare effects of external counterpulsation in treatment of heart failure patients of preserved ejection fraction type and reduced ejection fraction type.Methods:A prospective study was conducted on 108 patients with heart failure admitted to the cardiovascular department of the hospital from June 2019 to April 2021.According to their ejection fraction levels,54 patients with heart failure of preserved ejection fraction type were included in control group,and 54 patients with heart failure of reduced ejection fraction type were included in observation group.Both groups received external counterpulsation on the basis of routine symptomatic treatment.The levels of cardiac function indexes[left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter(LVEDD)and left atrial diameter(LAD)],the exercise tolerance[6 min walking distance(6 MWD)],the sleep quality[Pittsburgh sleep quality index(PSQI)]score,the quality of life[Minnesota living with heart failure questionnaire(LiHFe)]score,and the readmission rate were compared between the two groups before and after the treatment.Results:After the treatment,the levels of LVEF in the two groups were higher than those before the treatment,and the levels of LVEDD and LAD were lower than those before the treatment;however,there were no significant differences between the two groups(P>0.05).After the treatment,the 6 MWD levels of the two groups was longer than those before the treatment;however,there was no significant difference between the two groups(P>0.05).The PSQI and LiHFe scores of the two groups were lower than those before the treatment;however,there were no significant differences between the two groups(P>0.05).After 12 months of follow-up,there was no significant difference in the readmission rate between the two groups(P>0.05).Conclusions:The external counterpulsation in the treatment of the heart failure patients of preserved ejection fraction type and reduced ejection fraction type is similar.
