Pathomorphology of atherosclerotic coronary artery aneurysms and heart architectonics.
We evaluated pathognomonic incidence of atherosclerotic aneurysms in the anterior interventricular branch of the left coronary artery and proved greatest vulnerability of its first proximal segments. Positive correlations between the incidence of aneurysms in major coronary arteries and their size and bag-like shape were revealed. The characteristic aneurysm-dependent alterations of cardiac angioarchitectonics were found, which underlie pronounced shifts in coronary hemodynamics. Certain criteria for coronarographic diagnostics of atherosclerotic aneurysms were proposed with the methods of there correction. A thanatologic relation of coronary artery aneurysms to the nature of fatal complications is substantiated.
