[Variability in coronary risk assessment in HIV-infected patients].

Background And Objective: Antiretroviral treatment of human immunodeficiency virus (HIV)-infected patients seems to increase the coronary risk (CR) in these patients. Adequate assessment of CR has significant implications for the management of these patients. Our objective was to compare 2 systems for assessing 10-year CR in HIV-infected patients.

Patients And Method: CR was calculated in a prospective cohort of 205 HIV-infected patients using Framingham tables and REGICOR adapted tables. Prevalence of cardiovascular risk factors in these patients was evaluated.

Results: Mean age (standard deviation) was 41.4 (8.2) years. Most patients were taking antiretrovirals and had a good immunological status. Current smoking was reported by 77.1% of patients, while a history of dyslipidemia, hypertension, or diabetes was found in 29.3%, 7.3%, and 4.9% of patients, respectively. Lipodystrophy was seen in 41% of patients, abdominal obesity in 21.5%, and a sedentary lifestyle in 50.7% Mean values obtained were 6.55 (6.36) in the Framingham scale and 2.85 (2.31) in the REGICOR scale. A 10-year CR greater than 10% was found in 26 patients (12.9%) with the Framingham tables and in 4 patients (2.0%) with the REGICOR tables. The difference between both methods was significant (p < 0.001).

Conclusions: Application of the Framingham tables to our cohort may overestimate the CR. Studies aimed at identifying the most adequate method for measuring CR in HIV-infected patients are required. Until such data are available, estimation of CR in these patients should be taken with caution.
