Sarcopenia and myokines profile as risk factors in cardiovascular diseases?

Abstract

Skeletal muscles and substances released during physical activity (myokines) have a beneficial influence on the functioning of the organism. Myokines (released also by myocardium) together with hepatokines and adipokines play an important role not only in energetic metabolism, but they also influence, among others, the function of the circulatory and nervous systems, modulation of inflammatory state and atherogenesis. Under pathological conditions connected with the presence of chronic diseases, chronic inflammatory state, low physical activity, long-term immobility the following consequences are observed: reduction of muscle mass and strength (sarcopenia) and changed profile of released myokines. The incidence of sarcopenia is connected with an unfavorable course of the aging process, often leading to disability and multiple morbidities. Sarcopenia can also lead to frailty syndrome, which not only worsens the prognosis of various diseases, but it can also increase the risk of medical procedures. Sarcopenia and adverse myokine profile are modifiable risk factors of cardiovascular diseases and affecting them may improve functional status and prognosis. An important intervention to improve muscles function and myokine profile, apart from nutritional treatment and pharmacotherapy, is regular physical activity as a component of cardiac rehabilitation. In our paper we focused on a review of the newest research regarding the association of sarcopenia and the profile of released myokines with incidence and course of cardiovascular diseases such as chronic heart failure, coronary artery disease, carotid artery atherosclerosis or ischemic cerebral stroke.
