¿Existe relación entre la valoración del riesgo coronario según las tablas de Framingham y Sheffield con la del sexto informe del Joint National Committee? Relación entre tablas de riesgo coronario

Abstract

To find the distribution of coronary risk (CR) in the various groups of hypertense patients in the Joint National Committee (JNC VI), using both the Framingham and Sheffield tables, and to assess whether there is a relationship between the different scales used. Descriptive study. Tortosa Oeste Health District, Tarragona. Spain. Rural population between 30 and 74 years old with Hypertension, but without any background of cardiovascular pathology. The variables studied corresponded to the Anderson table in the Framingham study, the Sheffield table and the JNC VI one. Concordance was assessed with the kappa coefficient. 148 hypertense patients with an average age of 62, 63.5% of whom were women, were studied. 23% had high CR on the Framingham, and 42.1% on the Sheffield. Distribution of the sample according to the stratification of the JNC VI was: A, 16.2%; B, 51.4%, and C, 32.4%. High risk on the Framingham in the various groups of the JNC VI was: A, 0%; B, 9.2%, and C, 56.3% (kappa, 0.533). High risk on the Sheffield in the groups of the JNC VI ran at: A, 4.2%; B, 41.3%, and C, 66.7% (kappa, 0.324). There was moderate concordance between the Framingham tables and the JNC VI for calculation of CR in our population.
