To investigate the effect of exercise rehabilitation on frailty of elderly patients with coronary heart disease after percutaneous coronary intervention (PCI) .

From January to December 2021, 80 elderly patients with coronary heart disease who received PCI in Qinhuai Medical Area of General Hospital of Eastern Theater Command were selected as the study subject by convenience sampling. A total of 39 patients from January to June 2021 were set in the control group, and 41 patients from July to December 2021 were set in the experimental group. The control group was given routine nursing, and the experimental group was given systematic exercise rehabilitation on the basis of the control group. The effects of intervention were evaluated by Tilburg Frailty Index (FI) , Cardiac Exercise Self-Efficacy Instrument (CESEI) , cardiac function, exercise tolerance, and 6-minute Walking Distance (6MWD) .

There was no significant difference in FI and CESEI scores between the two groups before intervention (P>0.05) . After intervention, the FI score of patients in the experimental group was lower than that in the control group, and the CESEI score was higher than that in the control group, with statistically significant differences (P<0.05) . There was no significant difference in cardiac function, exercise tolerance and 6MWD between the two groups before intervention (P>0.05) . After intervention, there were statistically significant differences in cardiac function, exercise tolerance and 6MWD between the two groups (P<0.05) .

Exercise rehabilitation can effectively alleviate the frailty of elderly patients with coronary heart disease after PCI, improve their exercise compliance, cardiac function and exercise tolerance, which is worthy of clinical promotion.
