  • Background: HIV-infected individuals have high rates of myocardial infarction (MI). Traditional cardiovascular risk factors are clearly significant, but the role of antiretroviral therapy (ART) and HIV itself are still being evaluated.  Early protease inhibitors (PIs) were strongly associated with MI; the contribution of newer PIs is less well defined.  Additional risk factors, such as cocaine use and depression, are highly prevalent but inadequately explored.

    Methods: MIs among HIV+ patients followed at the Montefiore outpatient Center for Positive Living/ID Clinic were evaluated.  19 HIV+ patients with first MI between 2006-2009 were compared to 57 HIV+ clinic controls matched for age, year, and sex (including menopausal status).  All patients had standardized yearly comprehensive histories and screenings.  Traditional cardiovascular risk factors, end-stage renal disease (ESRD), CD4 counts, viral loads, and ART use, as well as nontraditional risk factors such as cocaine use, depression, and anxiety were examined.  Data was analyzed using SAS v9.1 software.

    Results: The average age of cases was 50 years; 58% were male.  Cocaine use was present in 12% of cases and 6% of controls.  Depression was present in 42% of cases and 40% of controls. Univariate analysis identified hypertension (p=0.05), ESRD (p=0.01), current NRTI use (p=0.05), current PI use (p<0.0001), current ART use (p<0.002), lower CD4 count (P=0.01), and lower CD4 nadir (p<0.005) as significant in cases.  In a multivariate analysis including all variables with a p value ≤0.20 (the above variables plus smoking, anxiety, and NNRTI use), only current PI use was significantly correlated with MI (OR = 11.3, 95% CI 2.9 – 43.6; p = 0.0005).

    Conclusion: Current PI use, even with newer generation PIs, remains independently associated with MI in HIV+ individuals, playing a greater role than traditional cardiovascular and other risk factors.  Cocaine use and depression were not associated with risk of MI in this small sample.  This analysis provides further evidence to support aggressive lowering of cardiovascular risk factors in PI-treated patients, and the increasing consideration of non-PI-containing regimens and new PI boosters without metabolic side effects.
