title: Incidence of systemic thromboembolic lesions in acute myocardial infarction.
abstract: In a series of 1277 cases of acute myocardial infarction, 30 episodes of systemic, noncerebral, thromboembolic lesions in 22 patients have been detected. Locations most frequently involved were the extremities (60%), kidneys (16.6%), spleen (13.3%), and mesentery (10%). The incidence of thromboembolism has been higher in patients over the age of 60. In the great majority of cases, the myocardial infarction has been anterolateral, often with a superimposed pump failure. Mortality has been very high (54.5%), perhaps in relation to the advanced age of the patients and to the extension of the infarction. Embolism at the extremities has been well treated with Fogarty's catheter. Among patients whose postmortem examination has been performed a high incidence of ventricular aneurysm (3 of 7) and mural thrombosis (5 of 7) has resulted. In the cases of ventricular aneurysm, episodes of atrial fibrillation have always occurred.
