PINTO, Diego A et al. Description of patients with non-valvular atrial fibrillation admitted to the emergency room. Rev. Colomb. Cardiol. [online]. 2016, vol.23, n.4, pp.270-276. ISSN 0120-5633.  https://doi.org/10.1016/j.rccar.2015.09.001.

Introduction and motivation: Atrial fibrillation is the most common cardiac arrhythmia. One of its most feared complications is the systemic embolism and/or the cerebrovascular accident (CVA) or stroke. Nowadays several antithrombotic therapies are available for the former; however, there are fears regarding complications related to anticoagulation, and even though recommendations of different clinical practice guidelines exist, blood-thinning drugs are still being underused. The goal of this study is to describe clinical, diagnostic and therapeutic data of patients admitted in the emergency room with atrial fibrillation; in addition, a correlation was made between the risk of systemic embolism and bleeding depending on the received treatment. Methods: Retrospective, descriptive study of case series of patients diagnosed with non-valvular atrial fibrillation during a year. Comorbidity frequencies, admission diagnoses and specific therapy types are reported. Results: 98 patients were included, average age was 72 years old, cardiac failure and high blood pressure were the main comorbidities; 92% showed an indication for anticoagulation therapy according to the CHA₂DS₂-VASc scale, 54% of those patients had not been receiving this therapy despite a low risk for bleeding was established for most of them. 5% of the patients received an admission diagnosis of ischemic stroke and 5% showed overanticoagulation. Conclusion: The characteristics of our sample with atrial fibrillation are similar to those described in the literature, but there is a low adherence to the treatment recommendations for anticoagulation therapy.
