Adecuación del tratamiento antitrombótico en los pacientes con fibrilación auricular no valvular. Registro AFINVA / Fine-tuning of antithrombotic therapy in patients with non-valvular atrial fibrillation. The AFINVA register

OBJETIVO: Conocer la adecuación del tratamiento antitrombótico (TAT) a las guías de práctica clínica en pacientes con fibrilación auricular no valvular. DISEÑO: Estudio observacional prospectivo. Emplazamiento: Centros de Salud de atención primaria y Servicio de Cardiología de un Departamento de Salud de la Comunidad Valenciana, España. PARTICIPANTES: Un total de 505 pacientes con diagnóstico de fibrilación auricular no valvular en la historia clínica electrónica de atención primaria. Mediciones principales: Pacientes con TAT inadecuado, definido como aquellos con puntuación CHA2DS2-VASc ≥ 1 que no reciban anticoagulación oral, los tratados con fármacos antivitaminaK y deficiente control de la anticoagulación, la antiagregación asociada inapropiadamente con anticoagulantes, y pacientes con CHA2DS2-VASc=0 y TAT. RESULTADOS: La edad media fue 77,4 ± 10 años. El TAT se estimó inadecuado en el 58% de los casos. Los factores relacionados de forma independiente con TAT inadecuado en la muestra global fueron la edad (OR: 1,02 (1-1,04); p = 0,029), el hipotiroidismo (OR: 1,98 (1,14-3,43); p = 0,015], el antecedente de cardiopatía isquémica (OR: 1,73 (1,15-2,59); p = 0,008) y la fibrilación auricular paroxística (OR: 2,11 (1,41-3,17); p < 0,0001). CONCLUSIONES: Los datos muestran la elevada prevalencia de tratamiento antitrombótico inadecuado en la práctica diaria, así como sus diversas causas

OBJECTIVE: To determine whether antithrombotic treatment (ATT) in patients with non-valvular atrial fibrillation in a health area complies with the recommendations of current clinical guidelines. DESIGN: Prospective observational study. LOCATION: Primary Health Care Centres and Cardiology Department of a Health Department of the Valencian Community, Spain. PARTICIPANTS: A total of 505 patients with nonvalvular atrial fibrillation were included in the study. MAIN MEASUREMENTS: ATT was deemed to be inappropriate in patients with a CHA2DS2-VASc score ≥ 1 and who were not under oral anticoagulation, in patients treated with antivitaminK drugs, and poor control of oral anticoagulation, or with antiplatelet therapy inappropriately associated with anticoagulation, and in patients on ATT with a CHA2DS2-VASc score = 0. RESULTS: The median age was 77.4±10years. The ATT was considered inadequate in 58% of cases. Factors independently associated with inadequate ATT were age (OR: 1.02 (1-1.04); P = .029), hypothyroidism (OR: 1.98 (1.14-3.43); P = .015), ischaemic heart disease (OR: 1.3 (1.15-2.59); P = .008) and paroxysmal non-valvular AF (OR: 2.11 (1.41-3.17); P < .0001). CONCLUSIONS: These data underline the high prevalence of inadequate ATT in daily practice, as well its different causes
