摘要
目的探讨基于六分钟步行训练的心脏康复模式对慢性心力衰竭患者易损期运动耐量的影响。方法选取2020年7月至2021年4月在重庆医科大学附属第一医院第一分院心血管内科符合标准的49例射血分数保留心力衰竭患者作为研究对象,采用随机数字表法分为试验组(n=25)和对照组(n=24)。对照组给予常规的出院心脏康复指导,试验组在对照组的基础上指导患者每天进行六分钟步行试验训练,持续12周,比较两组的再住院率、六分钟步行距离(6MWD)、血生化指标。结果试验组与对照组患者再住院率的比较,差异无统计学意义(P>0.05)。试验组与对照组患者6MWD的比较,差异无统计学意义(P>0.05);但随访12周后两组患者6MWD均长于出院前,差异有统计学意义(P<0.05)。试验组与对照组患者的血生化指标比较,差异均无统计学意义(P>0.05)。结论基于六分钟步行试验训练的心脏康复模式可以部分提高慢性心力衰竭患者的运动耐量,但差异无统计学意义,还需更大样本的研究来证实。同时也证实在慢性心力衰竭易损期进行适当的运动康复也是安全和切实可行。
Objective To investigate the effect of cardiac rehabilitation model based on six-minute walk training on exer-cise tolerance in vulnerable period of patients with chronic heart failure.Methods Forty-nine patients with heart failure with preserved ejection fraction meeting the criteria in the cardiovascular department of the First Branch of the First Affiliat-ed Hospital of Chongqing Medical University from July 2020 to April 2021 were selected as the study objects,and were di-vided into the experimental group(n=25)and the control group(n=24)by random number table method.The control group was given routine discharge cardiac rehabilitation guidance,and the experimental group was instructed to carry out six-minute walking test training every day on the basis of the control group for 12 weeks.The re-hospitalization rate,six-minute walking distance(6MWD),and blood biochemical indexes of the two groups were compared.Results There was no significant difference in the readmission rate between experimental group and control group(P>0.05).There was no sig-nificant difference in 6MWD between experimental group and control group(P>0.05).However,after 12 weeks of fol-low-up,6MWD was longer in both groups than before discharge,and the difference was statistically significant(P<0.05).There were no significant differences in blood biochemical indexes between experimental group and control group(P>0.05).Conclusion The cardiac rehabilitation model based on six-minute walking training can partially improve the exercise toler-ance of patients with chronic heart failure,but the difference is not statistically significant,and larger sample studies are needed to confirm.At the same time,it is also confirmed that appropriate exercise rehabilitation is safe and feasible in the vulnerable period of chronic heart failure.
