Microangioarchitectonics of the myocardial venous vessels in coronary heart disease.

The studies have been conducted on human hearts in the course of acute and chronic coronary insufficiency using microhistoangiographical method. Changes in the angioarchitectonics of the venous vessels in the course of myocardial infarction and also in chronic coronary insufficiency have been described. It was noted that the renovation of the vessels in the organizing infarcts begins from the venous pole with the participation of the intramuscular venous plexuses.
