Clinical analysis of acute myocardial infarction caused by coronary embolism
Abstract
Background: This study aims to investigate the clinical and angiographic features in patients with acute myocardial infarction (AMI) induced by coronary artery embolism.
Methods: Clinical data of five patients with AMI induced by coronary artery embolism were analyzed retrospectively.
Results: One patient had left atrial myxoma, one patient had non-valvular atrial fibrillation, and three patients had rheumatic heart disease. Furthermore, one patient had mitral mechanical valve prostheses, two patients had atrial fibrillation. Coronary angiography showed the absence of significant atherosclerostic lesions in the coronary arteries except infarct related artery in five patients. Angiography suggested the presence of IRA occlusion caused by embolism.
Conclusions: The status for AMI due to coronary artery embolism usually expresses embolic material originating from the left heart chambers. Rheumatic heart disease and atrial fibrillation are the common reasons for coronary artery embolism. Coronary artery occlusion is the common performance in the results of primary coronary artery angiography. Sometimes it expresses visible signs of embolism.
