Abstract
Background: Non-communicable diseases have increased in people living with HIV; in particular, the risk of developing cardiovascular disease is two-fold higher in HIV-positive individuals.
Methods: Forty HIV-positive participants and uninfected individuals were recruited from the Atlanta VA Medical Center. Cardiovascular risk factors were collected through physical exams and paper questionnaires, and the following biomarkers were measured: high-sensitivity C-reactive protein (hsCRP), galectin-3, amino terminal propeptide of B-type natriuretic peptide (NT-proBNP), troponin T (TnT), and 3-nitrotyrosine (3-NT). Cardiovascular health was defined using the American Heart Association’s Life’s Simple 7. Multivariable logistic regression and multiple linear regression was conducted to evaluate the association of HIV infection status with risk factors and biomarkers of interest.
Results: HIV-positive participants on average scored 1.7 points higher (95% confidence interval: 0.9, 2.4) than uninfected individuals for the measure of overall cardiovascular health. HIV-positive participants were more likely to report a history of smoking and moderate exercise and less likely to report being a current smoker, use of medications for cholesterol, and use of medications for blood pressure. Additionally, HIV-positive participants had higher concentrations of hsCRP, galectin-3, and TnT values, and lower NT-proBNP and 3-NT values; however, these findings were not statistically significant.
Conclusions: In general, HIV-positive participants had better levels of cardiovascular health than uninfected individuals; however, biomarker results indicate a potentially greater risk for cardiovascular disease in the future.
