Specific Characteristics of Coronary Atherosclerosis

In this review, we present modern aspects of etiology and pathogenesis of atherosclerosis. We describe the roles played by inflammatory cells, components of cellular response in allergic reactions, disturbances of carbohydrate metabolism, cellular aging, and infection at various stages of formation of atherosclerotic plaques. Special attention is given to the specific characteristics of atherosclerosis and calcification of coronary arteries. We show the influence of age and gender on the disease progression. The review includes information on the importance of myocardial bridges for the change of hemodynamics in segments of coronary arteries. The data presented indicate that differences in localization of atherosclerotic lesions between systems of the right and left coronary arteries depends on their hemodynamic, anatomical and physiological characteristics. According to the literature, anterior descending artery is more vulnerable in this respect.
