[Atherosclerosis in HIV-positive patients].

Worldwide, human immunodeficiency virus (HIV) infection is one of the main health subjects. Even, the human immunodeficiency virus primarily effects the immune system, HIV infection also has an impact on other organs. Cardiovascular manifestations in HIV-infected patients could occur by the HI-virus itself or by opportunistic infections. Reports of myocardial infarction in young HIV-infected patients, who received protease inhibitors, have raised concerns about premature arteriosclerosis and coronary artery disease in this population. In the pre-protease inhibitor era, autopsy reports were the first to describe an association between coronary artery disease and HIV infection. Long-term antiretroviral therapy, including protease inhibitors, significantly reduced mortality, morbidity and revolutionized the care of HIV-infected patients. However, class-specific metabolic side effects, such as elevated total cholesterol and triglyceride levels and insulin resistance, have been described. These metabolic alterations of antiretroviral therapy impair the cardiovascular risk profile of HIV-infected patients. Even epidemiological studies found no significant effect of antiretroviral treatment type on coronary heart disease or myocardial infarction, an increase of arteriosclerosis in HIV-infected patients is suspected. Recent results of autopsy studies and analyses of endothelial function in patients with HIV infection described an effect of HIV and antiretroviral therapy on premature arteriosclerosis. The present article gives an overview about arteriosclerosis and coronary events in HIV-infected patients and the impact of antiretroviral therapy.
