Introduction: Cardiovascular disease is a leading cause of morbidity and mortality in human immunodeficiency virus (HIV) infected adults, and should be managed more aggressively.Prior studies highlighted treatment disparities for Acute Coronary Syndrome (ACS) among HIV patients. This study aims at examining these disparities with the latest large cohort data. Hypothesis: HIV patient with ACS are as likely to receive cardiac revascularization related procedures compared to control group.
We reviewed the Nationwide Inpatient Sample from 2013 to 2016 to identify patients with diagnosis of ACS (ST-elevation and non ST-elevation myocardial infarction, and unstable angina) to compare rates of cardiac procedures (Catheterization, Percutaneous Coronary Intervention - PCI - and Coronary Artery Bypass Graft - CABG) among groups of population of interest (control, asymptomatic HIV, symptomatic HIV).
Overall, 515,016 patients with primary diagnosis of ACS where identified and among them 2066 (0.40%) of ACS patients had diagnosis of HIV (asymptomatic and symptomatic). Multivariate regression analysis showed statistically significant lower procedural rates for catheterization (OR: 0.62, 95% CI: [0.52, 0.73]), PCI (OR: 0.80, 95% CI: [0.67, 0.96]) and CABG (OR: 0.70, 95% CI: [0.52, 0.93]) in symptomatic HIV compared to control group. For asymptomatic HIV patient group, no significant change of procedural rates were found compared to control group for catheterization, PCI and CABG (respectively OR: 0.90, 95% CI: [0.78, 1.05], OR: 1.13, 95% CI: [1.00, 1.26] and OR: OR: 0.87, 95% CI: [0.72, 1.04]).
Analysis shows a treatment disparity for ACS for symptomatic HIV patients only as symptomatic HIV affected patients received less aggressive catheterization and revascularization management after ACS, compared to control group. However, this effect was not present for the asymptomatic HIV patient group.
