Dise？o de un registro multicéntrico para evaluar control de ritmo contra control de la frecuencia en fibrilación auricular: Registro Mexicano de Fibrilación Auricular (ReMeFA)

atrial fibrillation is the most common arrhythmia, predominantly affecting individuals older than 70 years of age. there is little information about its management in mexico, for this purpose the mexican registry of atrial fibrillation (remefa) was designed. methods: remefa is a prospective multicentric, observational registry concerning the treatment of atrial fibrillation in mexico. it includes patients 18 years and older, from both genders, with documented atrial fibrillation. patients with secondary atrial fibrillation from a reversible cause, previous treatment with pulmonary vein ablation (percutaneous or surgical), pacemakers or defibrillators, and with a life expectancy of less than one year, physically or mentally impaired for completing the protocol were excluded. clinical and demographic data were collected at enrollment and in two scheduled visits at 6 and 12 months. information about pharmacologic treatment for rhythm or rate control was particularly obtained. preliminary results: between december 2008 to july 2009, 1201 patients from 79 centers were enrolled. conclusion: this registry will provide valuable information about the strategy chosen by physicians in mexico for the treatment of atrial fibrillation.
