ABSTRACT

Objetivo: Determinar el grado de correlación y concordancia entre los principales esquemas de clasificación clínica (ECC) para predecir ECV en fibrilación auricular no valvular (FANV). Material y métodos: Durante el año 2004, a todos los pacientes con FANV se les aplicó los ECC AFI, SPAF, ACCP y CHADS2, y se analizó el grado de correlación y concordancia entre ellos. Resultados: El grado de correlación encontrado entre los esquemas CHADS2 y AFI (Tau-b =0.339, p menor que 0.001; rho =0.372, p menor que 0.001); CHADS2 y ACCP (Tau-b =0.257, p menor que 0.001; rho =0.284, p menor que 0.001); CHADS2 y SPAF (Tau-b =0.296, p menor que 0.001; rho =0.326, p menor que 0.001) fue de bajo a moderado. El grado de concordancia entre los esquemas AFI y ACCP fue muy bueno (k =0.865); entre los esquemas AFI y SPAF (k = 0.606) y entre ACCP y SPAF (k = 0.677) fue bueno; mientras que el encontrado entre los esquemas AFI y CHADS2 (k = 0.006), ACCP y CHADS2 (k = 0.004), y SPAF y CHADS2 (k = 0.003) fue insignificante. Conclusiones: Los ECC AFI, SPAF, ACCP y CHADS2 en general tienen un grado de correlación y concordancia bastante pobre.


Objective: To determine the degree of correlation and agreement between the main clinical classification schemes (ECC) in predicting CVD in non-valvular atrial fibrillation (NVAF). Material and methods: During 2004, we applied to all patients with NVAF the ECC AFI, SPAF, ACCP and CHADS2 in order to analyze the degree of correlation and agreement between them. Results: The degree of correlation found between the ECCÆs CHADS2 and AFI (Tau-b =0.339, p less than 0.001, rho =0.372, p less than 0.001), ACCP and CHADS2 (Tau-b =0.257, p less than 0.001, rho =0.284, p less than 0.001), and CHADS2 and SPAF (Tau-b =0.296, p less than 0.001, rho =0.326, p less than 0.001) was low to moderate. The degree of agreement between AFI and ACCP schemes was very good (k =0.865). Between the AFI and SPAF schemes (k =0.606) and between SPAF and ACCP (k =0.677) was good. While the correlations patterns found among AFI and CHADS2 (k =0.006), CHADS2 and ACCP (k =0.004) and CHADS2 and SPAF (k =0,003) was negligible. Conclusions: The ECC AFI, SPAF, ACCP y CHADS2 has in general a poor degree of correlation and agreement.
