Factores asociados al mal control de la anticoagulación con antivitaminaK en pacientes con fibrilación auricular no valvular atendidos en consultas de Medicina Interna y Neurología. Estudio ALADIN

espanolObjetivo Identificar los factores asociados con el mal control de la anticoagulacion con antagonistas de la vitaminaK (AVK) en pacientes con fibrilacion auricular no valvular (FANV) atendidos en consultas de Neurologia y Medicina Interna de Espana. Metodos Estudio transversal, multicentrico, anidado en el estudio ALADIN, de sujetos con FANV, tratados con AVK, atendidos en consultas de Medicina Interna o Neurologia de Espana. El grado de control de la anticoagulacion se estudio mediante el metodo directo y el de Rosendaal, considerando los 6meses previos a la inclusion. Resultados De los 1.337 pacientes incluidos en ALADIN, 750 estaban tratados con AVK, con informacion completa sobre el INR de los ultimos 6meses en 383 pacientes. Las puntuaciones medias del indice de Charlson, CHADS2, CHA2DS2-VASc y HAS-BLED fueron 1,94±1,54; 3,10±1,26; 4,63±1,54 y 2,20±0,90, respectivamente. El 46,2% y el 47,0% de los pacientes presentaban un control adecuado de la anticoagulacion por los metodos directo y Rosendaal, respectivamente. El control inadecuado de la anticoagulacion se asocio por el metodo directo con diabetes (OR: 2,511; IC95%: 1,144-5,659), antecedentes de INR inestable (OR: 35,371; IC95%: 15,058-83,083) y la realizacion de >6 controles en los ultimos 6meses (OR: 4,747; IC95%: 2,094-10,759), y por el metodo de Rosendaal, con los antecedentes de INR inestable (p Conclusiones Pese al alto riesgo tromboembolico, solo estaban bien controlados algo mas de la mitad. Los factores asociados al mal control de la anticoagulacion fueron la diabetes, INR inestable, >6 controles de INR y el HAS-BLED. EnglishObjective To identify factors associated with poor anticoagulation control with vitaminK antagonists (VKA) among outpatients with nonvalvular atrial fibrillation (NVAF) attended in Neurology and Internal Medicine in Spain. Methods Cross-sectional and multicenter study, from the ALADIN database, of outpatients with NVAF treated with VKA and attended in Internal Medicine and Neurology in Spain. Rates of anticoagulation control were determined with the direct and Rosendaal methods, considering data from the 6months before the inclusion. Results Out of 1,337 patients included in the ALADIN study, 750 were taking VKA, and complete information about INR values in the last 6months was available in 383 patients. Mean scores of Charlson Index, CHADS2, CHA2DS2-VASc and HAS-BLED were 1.94±1.54; 3.10±1.26; 4.63±1.54, and 2.20±0.90, respectively. 46.2% and 47.0% of patients had an adequate anticoagulation control according to the direct and Rosendaal methods, respectively. Inadequate anticoagulation control according to the direct method was associated with diabetes (OR: 2.511; 95%CI: 1.144-5.659), prior labile INR (OR: 35.371; 95%CI: 15.058-83.083) and the determination of >6INR controls in the last 6months (OR: 4.747; 95%CI: 2.094-10.759), and according to the Rosendaal method, with prior labile INR (P Conclusions Despite the high thromboembolic risk, only a little more than a half of patients were well controlled. Factors associated with poor anticoagulation control were diabetes, labile INR, >6INR controls and HAS-BLED.
