ABSTRACT: Introduction: Atrial fibrillation (AF) and heart failure (HF) are two closely related cardiovascular diseases, whose association worsens prognosis and is a major public health concern. The aim of this study was to assess the prevalence of AF in patients with chronic heart failure at the cardiology department of CHU Ignace Deen. Methods: This was a cross-sectional, descriptive study conducted over a 7-month period, from April 1 to November 30, 2024, of patients hospitalized for IC associated with AF. Results: Out of 377 admissions, 31 cases of IC associated with AF were identified, representing a hospital prevalence of 8.22%. The majority of patients were men (70.96%; sex ratio: 2.4), with an average age of 58.8 ± 12.4 years. The age groups most affected were 51 - 60 years (41%) and 71 - 80 years (22.5%). The main risk factors included arterial hypertension (48.38%), diabetes (22.58%) and smoking (16.22%). The most frequent etiologies of AF-associated CI were coronary artery disease (48.38%), hypertension (25.89%) and valvular heart disease (9.67%). CHA2DS2-VASc score ≥ 3 was present in 38.70% of patients. Direct oral anticoagulants (DACs) were the most widely used antithrombotic therapy (64.51%), while beta-blockers were the most prescribed antiarrhythmic drugs (58.06%), followed by digoxin (32.25%). Conclusion: The increase in coronary artery disease and hypertension in Africa is helping to make atrial fibrillation a frequent cardiac rhythm disorder in hospitals.
