Patrones y resultados del cambio de anticoagulantes orales directos en la fibrilación auricular no valvular: experiencia en la práctica clínica en España / Patterns and outcomes of switching direct oral anticoagulants in non-valvular atrial fibrillation: A real-world experience from Spain

Objetivos El objetivo consistía en evaluar un programa de gestión de anticoagulantes orales directos (ACOD) en pacientes con fibrilación auricular no valvular (FANV) según sus perfiles, idoneidad de la dosis, patrones de cambio de tratamiento, efectividad y seguridad Se trató de un estudio observacional, prospectivo y longitudinal en una cohorte de pacientes atendidos en la práctica clínica cotidiana en un hospital regional español con un plan de seguimiento de 3 años para pacientes que iniciaron el tratamiento con dabigatrán, rivaroxabán o apixabán entre enero de 2012 y diciembre de 2016. Métodos Se analizaron 490 episodios de tratamiento (apixabán 2,5mg, 9,4%; apixabán 5mg, 21,4%; dabigatrán 75mg, 0,6%; dabigatrán 110mg, 12,4%; dabigatrán 150mg, 19,8%; rivaroxabán 15mg, 17,8%; rivaroxabán 20mg, 18,6%) en 445 pacientes. En el 13,6% de los pacientes tratados con dabigatrán, el 9,7% de los tratados con rivaroxabán y el 3,9% de los tratados con apixabán se cambió a otros ACOD o se modificó la dosis. Resultados El ACOD al que se cambió con mayor frecuencia fue el apixabán. Los motivos más frecuentes para cambiar de tratamiento fueron toxicidad (23,8%), hemorragia (21,4%) y deterioro renal (16,7%). En el 23,8% de los episodios se constató una inadecuación de la dosis. Las tasas de ictus y accidentes isquémicos transitorios (AIT) fueron de 1,64 y 0,54 eventos/100 años/paciente, respectivamente, mientras que las de hemorragias importantes, no importantes, pero clínicamente relevantes (NICR) e intracraneales fueron de 2,4, 5 y 0,5 eventos/100 años/paciente, respectivamente. Las hemorragias digestivas y genitourinarias fueron el tipo más frecuente de eventos hemorrágicos. En el análisis multifactorial, el ictus previo y la edad fueron factores predictivos independientes de ictus/AIT. El uso concomitante de antiagregantes plaquetarios, el sexo masculino y la edad fueron factores predictivos independientes de eventos hemorrágicos (AU)

Aims The aim is to evaluate a management program for direct oral anticoagulants (DOACs) in non-valvular atrial fibrillation (NVAF) patients according to their profiles, appropriateness of dosing, patterns of crossover, effectiveness and safety. This is an observational and longitudinal prospective study in a cohort of patients attended in daily clinical practice in a regional hospital in Spain with 3-year a follow-up plan for patients initiating dabigatran, rivaroxaban or apixaban between Jan/2012 and Dec/2016. Methods We analyzed 490 episodes of treatment (apixaban 2.5, 9.4%; apixaban 5, 21.4%; dabigatran 75, 0.6%; dabigatran 110, 12.4%; dabigatran 150, 19.8%; rivaroxaban 15, 17.8% and rivaroxaban 20, 18.6%) in 445 patients. 13.6% of patients on dabigatran, 9.7% on rivaroxaban, and 3.9% on apixaban switched to other DOACs or changed dosing. Results Apixaban was the most frequent DOAC switched to. The most frequent reasons for switching were toxicity (23.8%), bleeding (21.4%) and renal deterioration (16.7%). Inappropriateness of dose was found in 23.8% of episodes. Rates of stroke/transient ischemic attack (TIA) were 1.64/0.54 events/100 patients-years, while rates of major, clinically relevant non-major (CRNM) bleeding and intracranial bleeding were 2.4, 5, and 0.5 events/100 patients-years. Gastrointestinal and genitourinary bleeding were the most common type of bleeding events (BE). On multivariable analysis, prior stroke and age were independent predictors of stroke/TIA. Concurrent platelet inhibitors, male gender and age were independent predictors of BE. Conclusion This study complements the scant data available on the use of DOACs in NVAF patients in Spain, confirming a good safety and effectiveness profil (AU)
