[Acute myocardial infarct: the importance of the coronary circulation type in the atherosclerotic lesion of the coronary arteries, the development of thromboses, the localization of the acute infarcts and their evolution]. / Ostur miokarden infarkt--znachenie na tipa koronarno kruvoobrashtenie za aterosklerotichnata porazenost na koronarnite arterii, razvitieto na trombozi v tiakh, lokalizatsiiata na ostrite infardti i tiakhnata evoliutsiia.

Analysis was made to 270 deceased with acute myocardial infarction. The signs discussed were: type of coronary circulation, sex and age, nosological belonging, atherosclerosis affection and allocation of thrombosis in coronary arteries. The acute infarction lesions were characterized according to site, layers involved, left ventricular mass engaged mural thrombosis and acute aneurysms ruptures. Consideration was given to myocardiosclerosis, postinfarction cicatrices and chronic aneurysms, hypertrophic rate, duration of recent infarction, thromboembolic complications and death causes. Essential discrepancies were found for the separate coronary types as regards stenosis distribution, predominating affection of separate coronary vessels, site of coronary thrombosis, infarction, resp., infarction extent (layer and mass), rupture incidence, acute aneurysms and postinfarction cicatrices. The study revealed that left coronary type was the most unfavourable terrain for acute myocardial infarction.

[Pathologicoanatomic analysis of deaths from acute myocardial infarct with and without arterial hypertension]. / Patologoanatomichen analiz na pochinali ot ostur miokarden infarkt sus i bez arterialna khipertoniia.

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.
