A questionnaire survey was used to collect demographic and disease data within 24 hours after PCI, and patients were evaluated by the Frailty Index. Results The incidence of frailty in elderly patients with coronary heart disease was 80.67% (242/300) . The univariate analysis showed that there were statistically significant differences in the incidence of frailty among patients with different ages, education background, financial status, insurance status, marital status, combined disease types, cardiac function classification, number of stents inserted, and whether smoking and consuming alcohol (P<0.05) . Multiple linear regression analysis showed that age, education, financial status, consuming alcohol, medical insurance status, number of comorbidities, and cardiac function classification were the influencing factors of frailty for elderly patients with coronary heart disease after PCI (P<0.05) . Conclusions Elderly patients with coronary heart disease have a high incidence of frailty after PCI. We should strengthening the frailty assessment in clinical practice, and take intervention in the high-risk population, so as to reduce the incidence of frailty amongelderly patientsafter PCI.
