Influence of sex on long-term prognosis in patients with atrial fibrillation treated with oral anticoagulants. Results from the prospective, nationwide FANTASIIA study.

BACKGROUND: While many risk factors for Atrial Fibrillation (AF) have been identified, there are important differences in their relative impact between sexes. The aim of our study was to investigate the influence of sex as a long-term predictor of adverse events in "real world" AF patients treated with direct oral anticoagulants. METHODS: The FANTASIIA registry is a prospective, national and multicentric study including outpatients with anticoagulated AF patients. Baseline characteristics and adverse events at 3 years of follow-up were collected and classified by sex. Cox multivariate analysis was performed to investigate the role of sex in major events and composite outcomes. RESULTS: A total of 1956 patients were included in the study. 43.9% of them were women, with a mean age of 73.8 ± 9.4 years (women were older 76.5 ± 7.9 vs 71.7 ± 10.1, p<0.001). Women had higher rate of cardiovascular risk factors and higher mean of CHA2DS2-VASc (4.4 ± 1.4 vs 3.7 ± 1.6, p<0.001) and HAS-BLED (2.1 ± 1.0 vs 1.9 ± 1.1, p<0.001) than men. After 3 years of follow-up, rates of major events were similar in both groups with limit difference for all-cause mortality (4.4%/year in women vs 5.6%/year in men; p = 0.056). However, all the composite events were more frequent in women. We observed in the non-adjusted adverse events lower rate of all-cause mortality (HR 0.62, 95%CI 0.47-0.81; p<0.001), composite 1 outcomes (HR 0.80, 95%CI 0.65-0.98; p = 0.029) and composite 2 (HR 0.77, 95%CI 0.64-0.94; p = 0.010) in women compared with men. In multivariate Cox regression analysis observed that female sex was an independently protector factor for all-cause mortality and for the composite outcomes 1 and 2. CONCLUSIONS: In this "real world" study of anticoagulated AF patients, women could have a protective role against development of adverse events, mainly on all-cause mortality and combined events.

Relation of quality of anticoagulation control with different management systems among patients with atrial fibrillation: Data from FANTASIIA Registry.

BACKGROUND: Anticoagulation control in patients with atrial fibrillation (AF) has a multidisciplinary approach although is usually managed by general practitioners (GP) or haematologists. The aim of our study was to assess the quality of anticoagulation control with vitamin K antagonists (VKAs) in relation to the responsible specialist in a "real-world" AF population. METHODS: We consecutively enrolled VKA anticoagulated patients included in the FANTASIIA Registry from 2013 to 2015. We analysed demographical, clinical characteristics and the quality of anticoagulation control according to the specialist responsible (ie GPs or haematologists). RESULTS: Data on 1584 patients were included (42.5% females, mean age 74.0 ± 9.4 years): 977 (61.7%) patients were controlled by GPs and 607 (38.3%) by haematologists. Patients managed by GPs had higher previous heart disease (53.2% vs 43.3%, P < .001), heart failure (32.9% vs 26.5%, P < .008) and dilated cardiomyopathy (15.2% vs 8.7%, P < .001) with better renal function (69.3 ± 24.7 vs 63.1 ± 21.4 mL/min, P < .001) compared to patients managed by haematologists. There was no difference between groups in the type of AF, CHA2 DS2 -VASc or HAS-BLED scores, but patients with electrical cardioversion were more prevalent in GP group. The overall mean time in therapeutic range (TTR) assessed by Rosendaal method was 61.5 ± 24.9%; 52.6% of patients had TTR<65% and 60% of patients had TTR<70%. TTR was significantly lower in patients controlled by haematologists than by GPs (63 ± 24.4 vs 59.2 ± 25.6, P < .005). CONCLUSIONS: About 60% of AF patients anticoagulated with VKAs had poor anticoagulation control (ie TTR<70%), and their management was only slightly better than when it is managed by general practitioners.

Tratamiento antiarrítmico actual de la fibrilación auricular no valvular en España. Datos del Registro FANTASIIA / Current antiarrhythmic therapy for nonvalvular atrial fibrillation in Spain. Data from the FANTASIIA Registry

Introducción y objetivos: Recientemente se han producido numerosas novedades en el manejo de la fibrilación auricular no valvular y el tratamiento antiarrítmico, anticoagulante y no farmacológico empleado, pero su aplicación a la clínica no es inmediata. El objetivo del trabajo es conocer las características generales de manejo y tratamiento antiarrítmico de una población general de pacientes con fibrilación auricular no valvular actualmente en España. Métodos: Estudio observacional y prospectivo de 1.318 pacientes consecutivos con fibrilación auricular no valvular, anticoagulados y reclutados entre junio de 2013 y marzo de 2014. Se analizan sus características generales, el manejo y el tratamiento antiarrítmico utilizado. Resultados: La media de edad era 73,8 ± 9,4 años; eran mujeres el 42,5%. La fibrilación auricular fue paroxística en el 28% de los casos, permanente en el 50%, persistente en el 17,6%, persistente de larga duración en el 4,5% y de novo en 66 pacientes (5%). Se eligió control del ritmo en el 39,4% de los casos y de frecuencia en el 60,6%. Tomaron bloqueadores beta el 60,2%, digoxina el 19,5% y antagonistas del calcio el 10,7%. Los antiarrítmicos empleados fueron amiodarona (12,6%), flecainida (8,9%), propafenona (0,4%), sotalol (0,5%) y dronedarona (2,3%). Se realizó cardioversión previa en el 41,9%, ablación en el 3,4% y cierre de orejuela en el 0,2%. Conclusiones Actualmente en nuestro país se maneja a los pacientes con fibrilación auricular no valvular preferentemente con control de frecuencia, sobre todo con bloqueadores beta, reciben pocos antiarrítmicos y se los somete en muy baja proporción a tratamientos no farmacológicos (AU)

Introduction and objectives: Recently, there have been many developments in the management of nonvalvular atrial fibrillation, antiarrhythmic and anticoagulant therapy, and nonpharmacological treatment, but these developments are not applied immediately in clinical practice. The aim of this study was to identify the overall management and antiarrhythmic therapy used in the current general population of patients with nonvalvular atrial fibrillation in Spain. Methods: A prospective, observational study of 1318 consecutive anticoagulated patients with nonvalvular atrial fibrillation, recruited between June 2013 and March 2014. We analyzed the patients’ general characteristics, management, and antiarrhythmic therapy. Results: Mean age was 73.8 ± 9.4 years; 42.5% were women. Atrial fibrillation was paroxysmal in 28% of the patients, permanent in 50%, persistent in 17.6%, long-standing persistent in 4.5%, and new-onset in 66 patients (5%). A rhythm control strategy was chosen in 39.4% of the patients and rate control in 60.6%. Beta-blockers were prescribed in 60.2% of the patients, digoxin in 19.5%, and calcium channel antagonists in 10.7%. The antiarrhythmic agents used were amiodarone (12.6%), flecainide (8.9%), propafenone (0.4%), sotalol (0.5%), and dronedarone (2.3%). Cardioversion had been performed previously in 41.9% of the patients, ablation in 3.4%, and atrial appendage closure in 0.2%. Conclusions: Currently, patients with nonvalvular atrial fibrillation in Spain are managed mainly with rate control, and beta-blockers in particular. They receive few antiarrhythmic agents and only a very small number of these patients undergo nonpharmacological treatments (AU)
