BACKGROUND: Atrial fibrillation (AF) is the most common sustained arrhythmia with serious clinical consequences in the absence of treatment. However, there are limited data on the treatment of these patients in Argentina. The objective was to describe the therapeutic management of patients with nonacute AF by Argentinean cardiologists and to determine the incidence of clinical events after 12 months follow-up. METHODS: The Atrial Fibrillation study in Argentina (FARAON) was an observational, descriptive, prospective, national, and multicentric study that included outpatients with AF, followed for 12 months. The study included 38 sites in Argentina. Each researcher included the first 10 patients who met the inclusion criteria of being over 21 and also being an AF carrier documented by electrocardiogram or Holter within 12 months prior to or at the time of enrollment. RESULTS: A total of 373 patients were included, mean age 70 ± 11.5 years, 40% women; 65% had AF rhythm at the time of inclusion, 57% had permanent AF, and 56% were asymptomatic. At the time of enrollment, 40% of physicians opted for rhythm control strategy. β-blockers and amiodarone were the most used drugs. Patients with rhythm control drugs had higher success rate than those with frequency control drug therapy (80% vs 57%). CONCLUSION: Cardiologists in Argentina receive patients with AF that are mostly permanent AF. More than half of the patients are asymptomatic. They opt primarily by controlling the pace. When choosing antiarrhythmic drugs, nearly half of them indicated amiodarone.
