Materials and Methods: This was a retrospective, multicentre, descriptive study from February 1<sup>st</sup>, to May 28<sup>th</sup>, 2019 carried out in the 3 hospitals of the city of Thies that focused on patients with AF documented by an ECG. Valvular and non-valvular AF classification was used and the CHA2DS2-VASc score was used to assess thromboembolic risk. Results: We collected 67 patients with a female predominance (M/F sex ratio of 0.71). The prevalence of AF was 1.7%. The average age of patients was 66.67 ± 13.48 years. Forty-eight patients (71.64%) had palpitations and 32 patients (47.76%) had heart failure. Hypertension was the most common etiological factor found in 41 patients (61.19%) followed by rheumatic valvular disease in 25 patients (37.31%). The non-valvular AF was found in 42 patients (62.69%) of which 34 (80.95%) had a CHA2DS2-VASc score ≥ 2. Vitamin K antagonists (VKAs) were prescribed in 47 patients (79.66%) and aspirin alone in 12 patients (20.34%). Direct Oral Anticoagulants (DOACs) were not prescribed in any patient. Seven patients (10.44%) had a medical regulator treatment and no electrical cardioversion was performed. Conclusion: AF was a frequent rhythm disorder. Hypertension and rheumatic mitral valve disease were the most frequently associated etiological factors. The diagnosis was often late in the heart failure stage. Anticoagulant treatment was insufficiently prescribed and based exclusively on VKAs.展开更多
