    Abstract: Introducción: La fibrilación auricular (FA) es la arritmia con mayor incidencia a nivel mundial y tiene una clara asociación con los síndromes coronarios agudos. El propósito de nuestro trabajo es describir la incidencia, los factores predisponentes y el pronóstico de pacientes con FA de novo luego de un síndrome coronario agudo, en una población representativa de nuestro medio. Material y métodos: Se realizó un subanálisis del registro BUENOS AIRES I, el cual incluyó 1110 pacientes con síndrome coronario agudo sin elevación del ST (SCASEST), con un seguimiento a 6 meses. Resultados: Se evidenció una incidencia del 7,7% de FA de novo y se identificaron como factores predictores independientes de su desarrollo la edad (OR 1,04; IC95% 1,02-1,08; p = 0,001), la presentación inicial con infarto agudo de miocardio (OR 2,35; IC95% 1,20-4,57; p = 0,012) y la necesidad de revascularización quirúrgica (OR 6,86; IC95% 3,95-11,89; p 〈 0,001). Los pacientes que desarrollaron FA presentaron mayor mortalidad por todas las causas, mayor mortalidad cardiovascular y eventos de sangrado BARC ≥2. Se identificó a la FA de novo post-SCASEST como un factor predictor independiente de mortalidad cardiovascular (OR 3,67; IC95% 1,25-10,76; p = 0,018) y sangrado a 6 meses BARC ≥2 (OR 3,024; IC95% 1,49-6,11; p = 0,002). Conclusiones: Este subanálisis preespecificado del registro BUENOS AIRES I demostró una incidencia significativa de FA de novo en el contexto de un SCASEST, vinculada a una mayor edad, mayor daño estructural cardíaco agudo y requerimiento de cirugía de revascularización, y con una peor evolución en términos de eventos clínicos adversos en el seguimiento a mediano plazo.

    Abstract: Background: The POPular AGE study demonstrated that in patients over 70 years of age clopidogrel would be the P2Y12 receptor inhibitor (P2Y12i) of choice due to its association with lower bleeding incidence and no difference in ischemic events. Objective: We analyzed the safety and efficacy of different treatment regimens with P2Y12i, in patients ≥70 years with non-ST-segment elevation acute coronary syndromes (NSTE-ACS) to test the “POPular AGE” hypothesis in the real world. Methods: This subanalysis of the prospective BUENOS AIRES I registry analyzed data corresponding to 1100 patients from 21 medical centers in Buenos Aires, Argentina, followed-up for 15 months. We considered the subgroup of patients ≥70 years, stratified according to the P2Y12i indicated at discharge. Results: This subgroup had a high burden of comorbidities, with 85.1% hypertension, 30.3% diabetes mellitus, and 43.2% chronic kidney disease. Patients treated with ticagrelor/prasugrel (n=54) presented with higher prevalence of active smoking, less atrial fibrillation and lower CRUSADE score, with no differences in the GRACE score, compared whit those treated with clopidogrel (n=286). At the 15-month follow-up, no significant differences were observed in the BARC ≥2 bleeding rate, with more events in the clopidogrel group, although without statistical significance, (25.4% vs. 18.2%; p=0.327) and a benefit in the incidence of major adverse cardiovascular events (MACE) in the ticagrelor/prasugrel treatment group (18.6% vs 36.3%, p= 0.023). Conclusions: In adequately selected patients with NSTE-ACS ≥70 years, treatment with Ticagrelor/prasugrel could be a safe and effective strategy.
