Abstract Objective To investigate the effect of cardiac rehabilitation model based on six-minute walk training on exercise 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 Affiliated Hospital of Chongqing Medical University from July 2020 to April 2021 were selected as the study objects, and were divided 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 significant difference in 6MWD between experimental group and control group (P＞0.05). However, after 12 weeks of follow-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 tolerance 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.
