Cardiovascular prevention in HIV patients: Results from a successful intervention program

ObjectivesTo analyze the effect of a prevention program on the estimated cardiovascular risk calculated by three risk scores.MethodsWe prospectively evaluated 87 HIV + patients with elevated cardiovascular risk estimation. Framingham (FRS), PROCAM and National Cholesterol Education Program (ATP-III) were applied. Cardiovascular risk was defined as elevated if >10%. All patients received non-pharmacological (diet, exercise, smoking cessation) and, when appropriate, pharmacological therapy.ResultsMean age was 52 years, 92% were male, 39.1% were smokers, 70.1% had hypertension, 18.4% had diabetes. All patients were under HAART, 56.3% were receiving protease inhibitors (PI). After 6 months, intervention was associated to significant changes on triglycerides (298 ± 242 and 206 ± 135 mg/dL, p < 0.05), total-cholesterol (224 ± 47 and 189 ± 38 mg/dL, p < 0.001), LDL-cholesterol (129 ± 44 and 109 ± 30 mg/dL, p < 0.001). Frequencies of patients with elevated cardiac risk before and 6 months after intervention were 92% × 27.6% (p < 0.0001), 80.5% × 50.6% (p < 0.0002), and 25.3% × 14.9% (p = 0.12), for FRS, ATP III and PROCAM, respectively.ConclusionsAn intervention program focused on reduction of traditional risk factors was able to decrease the frequency of patients with HIV infection and elevated cardiovascular risk estimation. FRS showed greater sensitivity than the other scores.
