Abstract:〔Abstract〕 Objective To analyze the physical recovery of patients with coronary heart disease after percutaneous coronary intervention (PCI) treatment, and analyze the risk factors for postoperative coronary artery restenosis in patients. Methods A total of 100 patients with coronary heart disease who underwent PCI treatment at Xinxiang First People's Hospital from January 1, 2021 to June 1, 2023 were selected as the research subjects. The international physical activity questionnaire was used to measure the physical of patients before and 7 days after surgery. Patients were divided into non recovery subgroup and recovery subgroup based on physical fitness scores. The marital status, self-efficacy, and other data of the two subgroups were collected and assigned values, and the risk factors for physical recovery of coronary heart disease patients after PCI treatment were analyzed. Follow up patients clinically for 6 months, and were divided into into restenosis subgroup and non restenosis subgroup based on whether they had coronary artery restenosis. Various data such as glycated hemoglobin, uric acid, homocysteine, total bilirubin, triglycerides, total cholesterol of the two groups were collected and assigned, and the risk factors of postoperative coronary restenosis were analyzed. Results The preoperative scale score of 100 patients enrolled was (51.03 ± 6.32) points, and the postoperative scale score at 7 days was (65.23 ± 4.15) points, with a statistically significant difference (P < 0.05). Multivariate logistic regression analysis showed that age, cardiac function grading and self-efficacy score were independent risk factors for postoperative physical recovery (P < 0.05). The patient was followed up for 6 months and showed 39 cases of coronary artery restenosis, with a restenosis rate of 39%. Multivariate logistic regression analysis showed that triglycerides and total cholesterol levels were independent risk factors for postoperative coronary artery restenosis (P < 0.05). Conclusion The physical strength of patients with coronary heart disease improved significantly after PCI, and age, cardiac function grade and self-efficacy score were independent risk factors for physical strength recovery. The incidence of coronary restenosis was higher in patients followed up for 6 months, and triglyceride and total cholesterol levels were independent risk factors for postoperative coronary restenosis.
