Retrospective Analysis of Interventional Treatment of Elderly Patients with Chronic Total Occlusion of Coronary Artery / 沈阳医学院学报

ABSTRACT

Objective:To explore characteristics and interventional treatment of the elderly patients with chronic total occlusion of coronary artery. Methods:According to the age,146 cases of coronary heart disease received interventional treatment of chronic total occlusion from Feb 2012 to Mar 2016 were divided into elderly group and youth group. Comparative analysis of characteristics and prognosis between the two groups was done. Results:The proportion of family history of coronary heart disease in elderly group was significantly lower than that in the young group (P<0.05), the incidence rate of occlusive vascular calcification or tortuosity and surgical intervention time were significantly higher than those in the young group (P<0.05) . After interventional treatment, LVEDD in elderly group was significantly lower than that in the young group (P<0.05),and LVEF,left ventricular aneurysm and wall motion abnormality rate had no significant differences (P>0.05) . Conclusions:Elderly patients with chronic total occlusion of coronary artery prone to calcification or tortuosity, interventional treatment takes a long time, success rate and adverse cardiovascular events had no difference compared with the young, postoperative cardiac function of elderly patients improved more obviously.
