Factors associated with high cardiovascular risk in a primarily African American, urban HIV-infected population

OBJECTIVE To determine factors associated with increased risk of developing cardiovascular disease in a high-risk patient population. DESIGN Cross-sectional analysis of a retrospective cohort study. METHODS One-hundred patients at an inner city HIV clinic in 2008 were reviewed. The atherosclerotic vascular disease risk score was calculated using the Pooled Cohort Equation. Chi-square test was performed to identify associations of potential risk factors with elevated atherosclerotic vascular disease risk. RESULTS Eighty-one participants were included in the final analysis. In total, 95.1% were African American, and 38.3% were women. The median atherosclerotic vascular disease risk score was 8.8% and 8.1% in 2008 and 2012, respectively. The medical co-morbidities associated with increased atherosclerotic vascular disease risk were hepatitis C infection (X2 = 3.93; p value = 0.048), elevated triglycerides levels (X2 = 4.0; p value = 0.046), and low albumin (X2 = 4.65; p value = 0.031). There were a higher number of women with known atherosclerotic vascular disease despite lower median atherosclerotic vascular disease risk score compared to men. CONCLUSION An elevated risk of developing cardiovascular disease persists in high-risk demographic groups of the HIV epidemic even in the current HIV era. There is an unexplained gender disparity and some non-traditional risk factors not accounted for in the Pooled Cohort Equation may be contributing to the excess cardiovascular disease risk observed among HIV-infected patients.
