Roles of Percutaneous Coronary Intervention in Improving Left Ventricular Function， Reducing Incidence of Cardiovascular Events of Patients With Ischemic Cardiomyopathy

［Abstract］Objective To investigate the roles of percutaneous coronary intervention in improving left ventricular function，reducing incidence of cardiovascular events of patients with ischemic cardiomyopathy. Methods Ninety cases of ischemic cardiomyopathy patients from August 2012 to August 2015 were randomly selected， these patients were divided into two groups， the study group（n = 45） and control group （n = 45） according to the random number table. The control group of patients were given routine treatment， while the study group of patients were given conventional treatment combined with percutaneous coronary intervention. Results The LVEDV， LVEF of the study group were significantly higher （P＜0.05）， the incidence of acute myocardial infarction onset， hospitalization rates again， mortality rate 8.89% （4/45）， 13.33% （6/45）， 2.22 % （1/45） were significantly lower than the control group 24.44% （11/45）， 40.00% （18/45）， 17.78% （8/45） （P＜0.05）. Conclusion Percutaneous coronary intervention can improve left ventricular function and reduce the incidence of cardiovascular events of patients with ischemic cardiomyopathy.
