Background: No studies have been published to date comparing SCORE, REGICOR and Framingham models. This study is aimed at analyzing how the REGICOR and SCORE functions classify cardiovascular risk, their correlation and concordance with Framingham (1998) and whether any differences exist among them with regard to the cardiovascular risk factors in high-risk groups. Methods: Descriptive cross-sectional study conducted in primary care. A total of 851 individuals within the 35-74 age range, free of cardiovascular diseases and selected by simple random sampling were included. A study was made of the percentage of high-risk patients with Framingham (≥20% ten-year risk), SCORE (≥5% ten-year risk) and REGICOR with cutoff points ≥20%, ≥15%, ≥10% and ≥5% at 10 years, given that with REGICOR ≥20% there are hardly any high-risk cases. A comparison was drawn between the correlation (Pearson´s r) and concordance (Kappa index) of the REGICOR and SCORE high-risk individuals as compared to Framingham. Results: The high-risk percentages respectively found were: 23.3% with Framingham; 15.2%; with SCORE; and 1.4%, 5.8%, 17.6% and 57.0% with REGICOR with the cutoff points described. REGICOR has a 0.99 correlation, SCORE a 0.78 correlation. REGICOR ≥10% showed a better concordance (Kappa 0.83) than SCORE (Kappa 0.61). On comparing the cardiovascular risk factors of the high-risk cases (≥20% Framingham, ≥5% SCORE and ≥10% REGICOR), SCORE showed higher prevalence of diabetes and a lower prevalence of hypercholesterolemia (p<0.05). Conclusions: REGICOR showed a good correlation with Framingham. With the ≥10% cutoff point, it classifies a number of individuals as high-risk similar to SCORE and fewer than Framingham. The SCORE model would treat a number of patients similar to the REGICOR ≥10% model with hypolipemiant drugs, however showing lesser evidence of effectiveness of the treatment.
Fundamento: No se dispone de estudios que hayan comparado SCORE, REGICOR y Framingham. El objetivo de este trabajo es estudiar cómo clasifican el riesgo cardiovascular las funciones REGICOR y SCORE, su correlación y concordancia respecto a Framingham (1998) y si presentan diferencias respecto a los factores de riesgo cardiovascular en los casos de riesgo alto. Métodos: Estudio descriptivo transversal realizado en atención primaria. Se incluyó a 851 personas entre 35-74 años, libres de enfermedades cardiovasculares y seleccionadas por muestreo aleatorio simple. Se estudió la proporción de pacientes de riesgo alto con Framingham (≥20% a 10 años), SCORE (≥5% a 10 años) y REGICOR con puntos de corte ≥20%, ≥15%, ≥10% y ≥5% a 10 años, ya que con REGICOR ≥20% apenas hay casos con riesgo alto. Se comparó la correlación (r de Pearson) y concordancia (coeficiente Kappa) de las personas de riesgo alto de REGICOR y SCORE respecto a Framingham. Resultados: Presentaron riesgo alto 23,3% con Framingham, 15,2% con SCORE y un 1,4%, 5,8%, 17,6% y 57,0% con REGICOR con los puntos de corte descritos, respectivamente. REGICOR tuvo una correlación de 0,99 y SCORE de 0,78. REGICOR ≥10% tuvo mejor concordancia (Kappa 0,83) que SCORE (Kappa 0,61). Al comparar los factores de riesgo cardiovascular de los casos con riesgo alto (≥20% Framingham, ≥5% SCORE y ≥10% REGICOR), el segundo presentó mayor prevalencia de diabetes y menor de hipercolesterolemia (p<0,05). Conclusiones: REGICOR presentó una buena correlación con Framingham. Con el punto de corte ≥10% clasifica como riesgo alto a un número de personas similar a SCORE e inferior a Framingham. El modelo SCORE trataría con hipolipemiantes a un número parecido de pacientes que el modelo REGICOR ≥10%, pero con menor evidencia de efectividad del tratamiento.
