Overview

Background Human immunodeficiency virus (HIV) infection is associated with a greater risk of cardiovascular disease (CVD). HIV infection causes a chronic inflammatory state and increases oxidative stress which can cause endothelial dysfunction and arterial stiffness. Aortic stiffness measured by carotid femoral-pulse wave velocity (cfPWV) and central hemodynamics are independent cardiovascular risk factors and have the prognostic ability for CVD. We assessed cfPWV and central hemodynamics in young individuals with recent HIV infection diagnosis and without antiretroviral therapy. We hypothesized that individuals living with HIV would present greater cfPWV and central hemodynamics (central systolic blood pressure and pulse pressure) compared to uninfected controls. Methods We recruited 51 treatment- naïve individuals living with HIV (HIV(+)) without previous CVD and 51 age- and sex-matched controls (HIV negative (−)). We evaluated traditional CVD risk factors including metabolic profile, blood pressure (BP), smoking, HIV viral load, and CD4 + T-cells count. Arterial stiffness and central hemodynamics were evaluated by cfPWV, central systolic BP, and central pulse pressure (cPP) via applanation tonometry. Results HIV(+) individuals presented a greater prevalence of smoking, reduced high-density lipoprotein cholesterol, and body mass index. 65.9% of HIV(+) individuals exhibited lymphocyte CD4 + T-cells count < 500 cells/μL. There was no difference in brachial or central BP between groups; however, HIV(+) individuals showed significantly lower cPP. We observed a greater cfPWV (mean difference = 0.5 m/s; p  < 0.01) in HIV(+) compared to controls, even after adjusting for heart rate, mean arterial pressure and smoking. Conclusion In the early stages of infection, non-treated HIV individuals present a greater prevalence of traditional CVD risk factors, arterial stiffness, and normal or in some cases central hemodynamics.
