Abstract
According to the World Health Organization, more than 38 million people are carriers of the human immunodeficiency virus (HIV). The relative risk of cardiovascular events in patients with HIV infection is 1.52 times higher than those without it. An HIV-positive status is associated with a 50% increased risk of acute myocardial infarction. The mechanisms of CVD development caused by HIV activity are not fully understood, and the contribution of traditional risk factors cannot fully explain such a high potential for coronary heart disease (CHD) in patients with HIV infection. Data suggest that HIV-associated chronic inflammation and immune system activation may lead to progressive endothelial dysfunction and vascular damage. The pathogenesis of atherosclerosis and, consequently, CHD in HIV infection is extremely versatile and poorly studied. The key mechanisms in HIV-associated CHD include the effect of HIV proteins on immunocompetent cells and vascular endothelium, immunodeficiency, translocation of microorganisms from the gut, and chronic inflammation with platelet activation. Despite considerable progress in understanding HIV-associated cardiovascular disease, many unresolved questions remain. Even with effective viral suppression, inflammation and immune dysregulation appear to increase the risk of cardiovascular complications. The lack of large-scale clinical studies on the prevention and treatment of cardiovascular disease in HIV is very important. Nevertheless, some important features should be considered in the management of patients with HIV infection.
