BackgroundHIV and HCV have been linked to an increased risk of cardiovascular disease (CVD). Their impact on long-term outcomes following ST-segment myocardial infarction (STEMI) has not been previously studied.MethodsWe leveraged data from a STEMI registry (n = 1208) at an inner-city health system to assess the influence of HIV and HCV on post-STEMI outcomes. Cox regression was used to compare HIV-monoinfected (n = 22), HCV-monoinfected (n = 26) and HIV-HCV-coinfected patients (n = 8) with the neither-infected group (n = 1152) with regard to death, death or any readmission, and death or CVD readmission.ResultsThe cohort was majority black or Hispanic. Median follow-up was 4.3 years. Compared to the neither-infected group, the HIV-monoinfected group showed near-significantly higher risks of death or any readmission (HR = 1.62, 95% CI = 0.96, 2.74) and death or CVD readmission (HR = 1.82, 95% CI = 0.98, 3.39) after full adjustment. On similar comparison, the HCV-monoinfected group exhibited significantly higher risks of death (HR = 2.09, 95% CI = 1.05, 4.15) and death or any readmission (HR = 1.68, 95% CI = 1.07, 2.65), whereas the HIV-HCV-coinfected group showed higher risk of death (HR = 6.51, 95% CI = 2.28, 18.61).ConclusionsIn this cohort composed mostly of race-ethnic minorities, HIV monoinfection tended to be associated with 1.6-to-1.8-fold higher risk of death or readmission for any cause or CVD over long-term follow-up compared to neither infection, whereas HCV monoinfection was associated with 1.7-to-2.1-fold higher risk of death and death or any readmission, and HIV-HCV coinfection with 6.5-fold higher risk of death. These associations require further study in larger populations, but highlight the importance of identifying and treating HIV and HCV in patients presenting with STEMI.
