[Pathologicoanatomic analysis of deaths from acute myocardial infarct with and without arterial hypertension].

Analysis was performed on 220 cases--decreased with acute myocardial infarction, subdivided into two groups--not hypertonics and hypertonics. The average age of the decreased with acute myocardial infarction with arterial hypertension is higher. Substantial differences are absent in the carriers of coronary type, degree of atherosclerotic affection and coronaries myocardiosclerosis and past infarctions, preceding the development of the acute myocardial infarction, being the cause of the death. Coronary thrombosis, mural thrombosis, acute aneurysms, and embolic complications in the systemic and pulmonary circulation proved to be more frequent among hypertonic. Discrepancies are absent as regards the localization of the necrotic zone and involvment of the ventricular muscles. Rupture incidence in both groups is very high and almost the same--over 25 per cent. External ruptures are found to be more frequent, being most often posterior in hypertonics. Parillary ruptures are characteristic for them. No difference is established concerning the exitus. Left ventricle insufficiency ranks first for both groups--over 67 per cent; second to follow are the heart ruptures with tamponade--about 20 per cent; and third--the arterial embolias in systemic circulation--9--10 per cent.
