[Acute myocardial infarct in embolizing abacterial thromboendocarditis (2 cases)]

Two patients are described, aged 60, with acute symptomless myocardial infarctions, diagnosed while still alive by electrocardiography, on the background of predominating neurological symptomatics, admitted as a manifestation of ischemic cerebral strokes, and in one of the patients--as embolization of peripheral artery, confirmed at operation. Multiple embolism and infarctions, with different duration, of brain and some other internal organs were established at necropsy, that originated from abacterial thromboendocarditis of aortic valve that developed in the absence of other diseases or data for the existence of disseminated intravasal coagulation. In the first case--extensive posterior-septal myocardial infarction was established and in the second--two not extensive infarctions, localized high anterior-septally and in the free anterior left ventricular wall. Though embolic deposits were not established in the large coronary arteries, the combination of acute myocardial infarctions and embolizing thromboendocarditis, in the absence of stenosing coronary atheromatosis, makes the embologenic origin of infractions most probable.
