Abstract
Currently, increasing evidence shows that people with cardiovascular diseases, including coronary heart disease, have a higher risk of developing pathologies such as sarcopenia, osteopenia, osteosarcopenia, sarcopenic, and osteosarcopenic obesity, which is associated with increased mortality risk. Musculoskeletal and adipose tissue changes have significantly affected the quality of life of patients and are important clinical problems. It is assumed that between the aforementioned disorders and coronary heart disease, a pathogenetic connection with the possibility of mutual aggravation exists. Accordingly, the search for relevant and accurate markers that reflect the severity and characterize the prognosis of a complex of pathological conditions is necessary given the increased proportion of patients in the general population with comorbidities. The article reviews the basic concepts of age-related disorders of body composition and molecular markers and emphasizes on new and potentially promising ones. The results can help in identifying and assessing the severity and prognosis of atherosclerosis, including coronary heart disease, and various disorders of musculoskeletal homeostasis, which reflects the commonality of their pathogenesis.
