[Ultrastructural characteristics of the myocardial microcirculatory bed in coronary arteriosclerosis]. 1981

V G Tsyplenkova, and A M Vikhert

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.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008833	Microcirculation	The circulation of the BLOOD through the MICROVASCULAR NETWORK.	Microvascular Blood Flow,Microvascular Circulation,Blood Flow, Microvascular,Circulation, Microvascular,Flow, Microvascular Blood,Microvascular Blood Flows,Microvascular Circulations
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009206	Myocardium	The muscle tissue of the HEART. It is composed of striated, involuntary muscle cells (MYOCYTES, CARDIAC) connected to form the contractile pump to generate blood flow.

D003327	Coronary Disease	An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.
