Role of vitamin D and its receptor in regulation of mechanisms of immune inflammation in patients with ischemic heart disease

Coronary heart disease still underlies high morbidity and mortality in people of working age. Thus, today one of the most important tasks facing clinical cardiology is the search for new molecular genetic predictors of coronary artery disease associated with the unfavorable course of this disease and the development of complications. In the present review, we analyzed the available data on the mechanisms of vitamin D interrelation with the development of immune inflammation in patients with coronary heart disease. The role of vitamin D and its receptor in cardiovascular diseases and in the development of coronary heart disease, in particular, is considered.Recent studies showed that vitamin D deficiency is a new risk factor for the development of atherosclerosis and immune inflammation. Immune damage of the vascular wall increases the risk of acute coronary syndrome, especially in patients with a predisposition to atherothrombosis. Vitamin D has a multilevel effect on immune inflammation mechanisms by restoring the balance in the system of pro- and anti-inflammatory cytokines. The protective effects of vitamin D on immune inflammation in the vascular wall are realized through vitamin D receptors. The present work re-viewed the studies describing possible mechanisms of immune inflammation regulation by vitamin D and its receptor and activation of immune inflammation in patients with vitamin D deficiency. Further studies of mechanisms of influence of vitamin D receptor on the suppression of immune inflammation are needed.
