[Atherosclerotic stenosis of the coronary arteries and contraction lesions of the myocardium in sudden coronary death].
Hearts of 50 patients (males of 30 to 54 years) after sudden cardiac death (SCD) without myocardial infarction, acute or recorded in the past, were studied. Heart slides were stained with an iron hematoxylin; polarizing microscopy was also used. The surface of cardiomyocytes diffusely stained with an iron hematoxylin was determined in histological slides by means of a 100-points ocular mesh. Essential differences in the spread of contractural myocardial lesions were found, this likely to be bound with different mechanisms of death (ventricular fibrillation, asystole). A low degree of spread of these lesions was noted more frequently in grave stenoses (greater than 75%) of coronary arteries. A direct correlation between the spread of contractural lesions and renin activity in plasma is found.
