Risk factors for coronary artery occlusion-induced myocardial infarction / 第二军医大学学报

ABSTRACT

Objective: To study the related factors of artery occlusion induced cardiac infarction. Methods: The coronary angiography data of 56 patients with total artery occlusion were retrospectively studied. The patients were divided into 2 groups: Group A with cardiac infarction, Group B without cardiac infarction, and the clinical features of the 2 groups were compared. Results: It was found that diabetes mellitus, anginal pectoris, hypercholesterolemia, high and low density lipoprotein, smoking, long term medication, collateral circulation, and changes of electrocardiogram presentation were all related factors of infarction( P 6 months), long term medication, well controlled blood glucose and lipoprotein, and non smoking, probably because these factors can improve the collateral circulation and induce ischemia preconditioning.
