Pathomorphological Criteria for Cardiosclerosis and Angioarchitectonics of the Hypertrophic Myocardium in Hypertensive Heart

We performed a pathomorphological study of 200 hearts with cicatricial changes from patients died from hypertensive disease. Most postinfarction scars in men were transmural and localized in the anterior and posterior wall of the left ventricle and in the interventricular septum. Non-transmural scars were revealed in the lateral wall (primarily in women). Pathognomonic changes in the architectonics of the heart included reduction of regional blood flow and segmentary, discontinuously extended, and diffusely extended atherosclerotic obstruction. Changes in the index of blood supply to the myocardium corresponded to pronounced decrease in vascularization of the hypertrophic left ventricle. A correlation was found between the index of blood supply to the myocardium and mean systolic and diastolic blood pressure. Therefore, the coronary bed did not satisfy the demands of hypertensive heart with cicatricial changes.
