A matched cohort study was conducted comparing patients with first-time acute coronary syndromes infected with human immunodeficiency virus (HIV) to non-HIV-infected patients with and without diabetes matched for smoking, gender, and type of acute coronary syndrome who underwent first-time coronary angiography. A total of 48 HIV-infected patients were identified from a national database. Coronary angiography showed that the HIV-infected patients had significantly fewer lesions with classification B2/C than the 2 control groups (p <0.001) but the same extent of multivessel disease. The HIV-infected patients were a decade younger than the non-HIV-infected controls and had significantly higher concentrations of total cholesterol (6.3 vs 4.8 and 4.5 mmol/L, p <0.0001), low-density lipoprotein (4.0 vs 2.9 and 2.5 mmol/L, p <0.001), and triglycerides (2.8 vs 1.0 and 1.4 mmol/L, p <0.01) compared to the nondiabetic and diabetic non-HIV-infected groups, respectively. In conclusion, HIV-infected patients with first-time acute coronary syndromes have fewer complex lesions than non-HIV-infected patients. This finding supports the idea that the pathogenesis of atherosclerotic disease in HIV patients is different from that in the general population.
