| pubmed-article:2604569 | pubmed:abstractText | It is widely known that other causes than recent coronary thrombosis may precipitate acute myocardial infarction in the presence of coronary atherosclerosis. A 48 year old male patient was admitted due to acute coronary insufficiency. The ECG showed anterolateral necrosis and lateral ischemia. Despite medication angina persisted and he died immediately after coronary angiography. At autopsy, established coagulation necrosis was observed in the internal half and the subendocardium of the lateral and posterior walls, of the left ventricle. Early coagulation necrosis occupied the inner half of the anterior, posterior and septal walls. Severe atherosclerotic coronary lesions were found in all major coronary trunks. An extensive panarteritis, involving extra and intramyocardial branches, consisting of mononuclear cells and prominent edema, was observed. A mixed mechanism may be invoked to explain the extensive myocardial necrosis: panarteritic infiltrates and extensive edema and humoral-induced coronary spasm. | lld:pubmed |
