Abstract

Objective: To investigate the anatomical and clinical characteristics of percutaneous coronary intervention after stent implantation. Methods: 275 elderly patients with coronary heart disease diagnosed by coronary angiography and undergoing percutaneous coronary intervention (PCI) were enrolled in this study. They were divided into male group (158 cases) and female group (117 cases) according to gender. To analyze the anatomical abnormal coronary artery and summarize the percutaneous coronary intervention treatment of abnormal origin and narrow coronary artery. Results: The basic clinical features of the two groups were similar. However, the number of women with type 2 diabetes is significantly higher than that of men, with significant statistical difference; The total success rate of percutaneous PTCA in 275 patients with coronary heart disease was 96.4%, and the success rate of treating lesions was 93.4%. There was no significant difference between male and female in coronary artery distribution (P > 0.05). There was no difference between male and female in detecting anatomical variation of coronary artery (P >0.05). Compared with the results of two-year follow-up, there was no significant difference in recurrence rate of angina pectoris, readmission rate, repeated revascularization of target lesion and serious adverse cardiac events between the two groups P> 0.05). Conclusion: Type 2 diabetes mellitus is more common in elderly women with coronary heart disease. The coronary artery lesions in both groups were mainly double-branch and three-branch lesions, and were characterized by B2 and C lesions. PCI is safe and feasible for coronary artery stenosis with abnormal origin.
