Abstract

Objective: To analyze trends in management and outcomes of patients infected with the human immunodeficiency virus (HIV) undergoing percutaneous coronary intervention (PCI) for an acute myocardial infarction (AMI) in the United States. Background: Infection with HIV is an independent risk factor for accelerated atherosclerosis associated with higher rates of AMI. Current trends and outcomes of HIV-infected individuals presenting with AMI in the United States remain unknown. Methods: Using the Healthcare Cost and Utilization Project National Inpatient Sample database we identified HIV-infected individuals who underwent PCI for an AMI from 2002 to 2013. Multivariable logistic regression and propensity-score matching were performed to analyze outcomes. Results: We identified a total of 59 194 patients of which 7841 underwent PCI during index hospitalization (13.3%). Most patients were men (71%), ≥50 years of age (82%), and white (74%). ST-elevation myocardial infarction was present in 21% of cases. Charlson comorbidity index (CCI) was 5.67 ± 0.4. Predictors of post-procedural complications included female sex, black race, higher CCI, and placement of a bare metal stent, whereas predictors of mortality included occurrence of a complication, ST-elevation myocardial infarction, age ≥70 years, and higher CCI. Conversely, placement of a drug-eluting stent was associated with a reduced risk of complications and mortality. After propensity-score matching, HIV-infected individuals were less likely to undergo PCI and receive a drug-eluting stent, while having longer length of stay, higher hospitalization costs, and higher in-hospital mortality when compared to non-infected individuals. Conclusion: Significant disparities continue to affect HIV-infected individuals undergoing PCI for AMI in the United States.
