Concordancia entre las escalas de riesgo cardiovascular PROCAM y Framingham en varones que reciben tratamiento antirretroviral en un hospital nacional de Lima, Perú 2013

Objectives. The aim of the study is to determine the concordance between the PROCAM (Prospective Cardiovascular Münster) and Framingham scales in patients receiving highly active antiretroviral therapy (HAART). Materials and methods. A cross sectional study was conducted in HIV-positive male population who use HAART in a national reference hospital located in Lima, Peru. To evaluate the concordance between the two scales the graphic method of Bland and Altman was used, for the evaluation of the correlation we used the Pearson coefficient and to measure the agreement we use the kappa coefficient. Results. 111 patients were enrolled, with an average age of 47.0 years. The distribution of patients according to the risk was low, moderate and high, 81.2%, 13.6% and 5.4% respectively for PROCAM and 71.2%, 25.2% and 3.6% for Framingham. According to the graphic method of Bland and Altman, the concordance was adequate in low values and was lost as the risk score increased. Pearson’s test found a strong correlation (r=0.87 and p<0.05) and the kappa coefficient was 0.56 (p<0,001). Conclusions. The agreement we found at low risk decreases as the risk increases. Strong correlation was found between the two scales. We recommend further studies in order to know which scale of cardiovascular risk is the most optimal scale for clinical practice among HIV population who receive HAART.
