Social Disparities among Sudden Death victims with HIV

Although cardiovascular death is a growing source of mortality for people living with human immunodeficiency virus (HIV), the risk factors and circumstances surrounding sudden death in this population are poorly understood. We compared 399 adult sudden death victims reported by Emergency Medical Services in North Carolina to 1,114 controls. Sudden death was more common among HIV-positive than HIV-negative individuals (OR: 2.59, 95% CI: 1.15-5.83). In a multivariable model of sudden death victims including Black race, BMI, and history of divorce, incarceration, substance abuse, and respiratory disease, HIV-positive individuals were more likely to be Black (adjusted OR [aOR]: 6.04, 95% CI: 1.08-33.7) or divorced (aOR: 4.71, 95% CI: 1.04-21.3), adjusted for all other variables in the model. Compared to controls with HIV, sudden death victims with HIV were more likely to have a history of incarceration, divorce, respiratory disease, alcohol abuse, or dyslipidemia. A qualitative assessment of victims suggested that many died in isolation, suffering from past and current substance abuse and depression. HIV infection appears to be an important risk factor for sudden death, and incarceration history, social isolation, and medical comorbidities contribute to sudden death risk for HIV-positive individuals.
