Anatomical characteristics of the main branches of the right coronary artery in elderly people with different somatotypes

A retrospective study was conducted on 97 lifetime coronary angiograms of elderly people without identified pathology of the coronary arteries. 35 archival records were reviewed in people with a normosthenic body type, and 31 coronary angiograms for each somatotype in hypersthenics and asthenics. The study selected coronary angiogram records of hearts with a right variant of coronary branching. The Pignet index was used to rank people according to body types. Morphometric indicators (diameter, length) were set in a special computer program RadiAnt DICOM Viewer, and the tortuosity coefficient was calculated using the capabilities of the Microsoft Excel computer program. It was determined that in people with a hypersthenic body type, the diameter of the initial section of the right marginal and posterior interventricular branches prevails over its values in normosthenics and asthenics. The right marginal branch reaches its greatest length in the hearts of hypersthenics. It is noted that in people of all somatotypes, the tortuosity coefficient is greater in the right marginal branch compared to its value in the posterior interventricular branch. With all body types, minor tortuosity of the main branches of the right coronary artery is most often encountered. Expressed tortuosity of the right marginal and posterior interventricular branches is most rarely determined in asthenics and normosthenics.
