Cardiovascular complications in HIV-infected individuals

PURPOSE OF REVIEW: This review updates the relationship between HIV and cardiovascular abnormalities in the context of the pathophysiology of coronary artery disease.RECENT FINDINGS: The evaluation of cardiovascular risk in patients with HIV hinges upon a complex interplay of direct and indirect vascular effects of HIV infection, antiretroviral therapy, aging, and exposure to cardiovascular risk factors. Carotid artery intima-media thickness and endothelial-dependent flow-mediated vasodilatation of the brachial artery, which gives an indication of the structural and functional aspect of the endothelium as well as soluble biomarkers, can help to assess the potential harm and benefits of antiretroviral drugs and address the residual burden of cardiovascular risk in the HIV population.SUMMARY: Given the complex pathophysiology of cardiovascular disease, no single biomarker is likely to be able to provide a universal surrogate whereby change observed independently predicts benefit, increased risk, or no effect across all drugs and mechanistic targets. Investigations and treatments must be tailored in the single patient according to non-modifiable and modifiable risk factors, including exposure to highly active antiretroviral therapy. With proper risk stratification altering the approach to highly active antiretroviral therapy, lifestyle changes, and lipid-lowering medications are the basis for reducing cardiovascular risk in HIV-infected patients.
