HIV Infection and Coronary Heart Disease: An Intersection of Epidemics

Patients with human immunodeficiency virus (HIV) infection are at increased risk of developing coronary heart disease (CHD). Although factors potentially contributing to this elevated risk include traditional CHD risk factors and antiretroviral medications, more recent data support a role for inflammatory and immunologic factors as central to a complex mechanism. Decreasing CHD risk among HIV-infected patients is likely to involve modification of inflammatory and immunologic factors through antiretroviral therapy or other novel strategies as well as targeted treatment of traditional CHD risk factors. This review will highlight epidemiologic data investigating the association between HIV and CHD outcomes. An overview of potential mechanistic factors associated with CHD in HIV infection and of strategies for managing CHD risk in HIV-infected patients is also included. Specific cardiovascular and metabolic risk factors, CHD risk prediction, and the immunologic basis for CHD in HIV-infected patients will be discussed in separate reviews.
