[Ultrastructural characteristics of the myocardial microcirculatory bed in coronary arteriosclerosis].
Myocardial microcirculatory bed was studied using ultrastructural analysis in 28 males, aged 30 to 55, who suffered from coronary atherosclerosis and died suddenly. The authors found a lowered capillaries/myocytes ratio. A part of myocardial capillaries were excluded from hemocirculation due to obturation of their lumen with endothelial microvilli and blood cells. Open capillaries showed signs of activation of adaptational mechanisms of compensation of myocardial microvascular bed insufficiency.
