Abstract: Background: Delays in catheterization (cath) in HIV-infected persons may worsen cardiac morbidity resulting in more significant coronary artery disease (CAD) at diagnosis. Methods: Data were collected on HIV+ patients from academic medical center HIV specialty clinics undergoing first cath for chest pain (CP) or suspected CAD and compared to a control population of randomly selected HIV - persons of similar sex, age and socioeconomic background also undergoing first cath for CP/CAD. Outcome measures: significant CAD (≥50% lesion in ≥ 1 major vessel) and indication for cath. Differences between groups tested by Fisher’s exact, Wilcoxon, Kruskal-Wallis rank tests. Results: 96 HIV+ patients were identified and compared to 41 HIV- controls. ESRD was significantly more common among HIV+ patients; DM more prevalent among HIV- patients. Tobacco use/male gender trended towards being more common in HIV+ patients. HIV+ patients were significantly more likely to have cath done urgently [unstable angina (UA) or myocardial infarction (MI)]. Prevalence of significant CAD was similar between groups, as was subsequent management. Conclusions: Significant CAD was very common in HIV+ patients going for cath (63%) despite the young median age of 49 years. In contrast, it was very difficult to find HIV-uninfected controls of comparable age/sex with suspected CAD. The high proportion of HIV+ caths for MI or UA suggests health care providers may not consider CAD early enough in younger HIV+ patients. Earlier recognition of CAD in HIV-infected patients may help improve outcomes.
