Abstract
Background: Previous studies have demonstrated that people with HIV have an increased atherosclerotic plaque vulnerability, making them more susceptible to severe cardiovascular complications. This study aimed to examine the clinical characteristics of people with HIV in comparison to people without HIV admitted to Veterans Health Administration (VHA) with their first major acute cardiovascular events (MACE) and compare their total mortality.
Methods: We used national VHA data to extract data of those admitted to VHA hospitals with MACE defined as acute myocardial infarction (AMI), acute cerebrovascular accident (CVA) or cardiac arrest during the fiscal years 2003-2021. The hazard ratio (HR) of mortality for people with HIV versus people without HIV was estimated using Cox proportional hazard regression analysis.
Results: Out of 280 311 veterans, 2510 people with HIV and 277 801 people without HIV had their first MACE during the study period. People with HIV were younger, more likely to be African American, had a lower prevalence of diabetes mellitus and hypertension, similar total cholesterol levels and a lower mean 10-year cardiovascular risk score (25.4 in people with HIV vs. 28.7 in people without HIV). Among MACE components, people with HIV had a higher proportion of CVA (27% vs. 21.3%, p < 0.001) and cardiac arrest (13.0% vs. 8.4%, p < 0.001) but a lower incidence of AMI (62.4% vs. 72.5%, p < 0.001) than people without HIV. Additionally, people with HIV had a higher risk of total mortality (adjusted HR: 2.05, 95% confidence interval: 1.90-2.22) compared with people without HIV.
Conclusion: People with HIV experience MACE at younger ages despite lower cardiovascular risks and similar baseline cholesterol and blood pressure levels. People with HIV had higher mortality and a higher risk of having ventricular fibrillation arrest and stroke as their first MACE.
期刊介绍:
HIV Medicine aims to provide an alternative outlet for publication of international research papers in the field of HIV Medicine, embracing clinical, pharmocological, epidemiological, ethical, preclinical and in vitro studies. In addition, the journal will commission reviews and other feature articles. It will focus on evidence-based medicine as the mainstay of successful management of HIV and AIDS. The journal is specifically aimed at researchers and clinicians with responsibility for treating HIV seropositive patients.
