Dabigatran versus vitamin K antagonists for atrial fibrillation in clinical practice: final outcomes from Phase III of the GLORIA-AF registry.
Research article published in Clinical research in cardiology : official journal of the German Cardiac Society (2022)
Abstract
BACKGROUND: Prospectively collected, routine clinical practice-based data on antithrombotic therapy in non-valvular atrial fibrillation (AF) patients are important for assessing real-world comparative outcomes. The objective was to compare the safety and effectiveness of dabigatran versus vitamin K antagonists (VKAs) in patients with newly diagnosed AF. METHODS AND RESULTS: GLORIA-AF is a large, prospective, global registry program. Consecutive patients with newly diagnosed AF and CHA2DS2-VASc scores ≥ 1 were included and followed for 3 years. To control for differences in patient characteristics, the comparative analysis for dabigatran versus VKA was performed on a propensity score (PS)-matched patient set. Missing data were multiply imputed. Proportional-hazards regression was used to estimate hazard ratios (HRs) for outcomes of interest. Between 2014 and 2016, 21,300 eligible patients were included worldwide: 3839 patients were prescribed dabigatran and 4836 VKA with a median age of 71.0 and 72.0 years, respectively; > 85% in each group had a CHA2DS2-VASc-score ≥ 2. The PS-matched comparative analysis for dabigatran and VKA included on average 3326 pairs of matched initiators. For dabigatran versus VKAs, adjusted HRs (95% confidence intervals) were: stroke 0.89 (0.59-1.34), major bleeding 0.61 (0.42-0.88), all-cause death 0.78 (0.63-0.97), and myocardial infarction 0.89 (0.53-1.48). Further analyses stratified by PS and region provided similar results. CONCLUSIONS: Dabigatran was associated with a 39% reduced risk of major bleeding and 22% reduced risk for all-cause death compared with VKA. Stroke and myocardial infarction risks were similar, confirming a more favorable benefit-risk profile for dabigatran compared with VKA in clinical practice. Clinical trial registration https://www.

Resumen
Dabigatran versus vitamin K antagonists for atrial fibrillation in clinical practice: final outcomes from Phase III of the GLORIA-AF registry.
Por qué esto importa para la hirudoterapia
Utilizando el gran registro prospectivo GLORIA-AF con emparejamiento por puntaje de propensidad, este análisis de la vida real de pacientes con fibrilación auricular recién diagnosticada informó que dabigatran se asoció con un riesgo 39% menor de sangrado mayor (HR 0,61, IC del 95% 0,42-0,88) y un riesgo 22% menor de muerte por todas las causas (HR 0,78, IC del 95% 0,63-0,97) versus antagonistas de la vitamina K, con riesgo similar de ictus e infarto de miocardio. El vínculo de la hirudoterapia es mecanístico: dabigatran es un inhibidor directo de la trombina sintético, el mismo objetivo molecular que la hirudina derivada de lombrices bloquea, por lo que este registro ayuda a consolidar la credibilidad clínica de la inhibición directa de la trombina como una estrategia anticoagulante que el secreto de la lombriz encarna en forma natural. Nota honesta: esto son datos de registro observacionales, no un ensayo aleatorio, y evalúa un fármaco de pequeña molécula oral, no la terapia de lombrices; el mecanismo compartido de inhibición de la trombina es una analogía, no evidencia sobre la hirudoterapia en sí.
