This systematic review summarizes the data on the prevalence, risk factors, complications, and management of atrial fibrillation (AF) in sub‐Saharan Africa (SSA). Bibliographic databases were searched from inception to 31 May 2019, to identify all published studies providing data on AF in populations living in SSA. A total of 72 studies were included. The community‐based prevalence of AF was 4.3% and 0.7% in individuals aged ≥40 years and aged ≥70 years, respectively. The prevalence of AF ranged between 6.7% and 34.8% in patients with ischemic stroke, between 9.5% and 46.8% in those with rheumatic heart disease (RHD), between 5% and 31.5% in patients with dilated cardiomyopathy. The main risk factors for AF were hypertension, affecting at least one‐third of patients with AF, and valvular heart disease (12.3%‐44.4%) and cardiomyopathy (~20%). Complications of AF included heart failure in about two thirds and stroke in 10% to 15% of cases. The use of anticoagulation for stroke prevention was suboptimal. Rate control was the most frequent therapeutic strategy, used in approximately 65% to 95% of AF patients, with approximately 80% of them achieving rate control. The management of AF was associated with exorbitant cost. In conclusion, AF seems to have a higher prevalence in the general population than previously thought and is mostly associated with hypertension, cardiomyopathy, and RHD in SSA. It is associated with a high incidence of heart failure and stroke. The management of AF is suboptimal in SSA, especially with a low uptake of oral anticoagulation.

Atrial fibrillation (AF) represents a significant global public health concern, particularly due to its association with adverse health outcomes such as stroke and heart failure. In Nigeria, where the burden of cardiovascular diseases is rising, understanding the prevalence and impact of AF is crucial for effective healthcare planning and intervention strategies.This review examines the epidemiology of AF in Nigeria, comparing it with global and African data. It explores demographic and regional variations, comorbidity factors, and the impact of AF on the healthcare system, mortality, and quality of life.Notably, the prevalence of AF in Nigeria generally falls just under 5%, but this figure rises to approximately 9% in stroke patients and 11-20% among those with heart failure (HF). Rheumatic heart disease (RHD) is identified as a significant AF risk factor within Africa, affecting around 20% of AF patients -a stark contrast to the 2% in North America. AF's association with higher mortality rates and functional deterioration highlights the urgent need for improved diagnostic and therapeutic approaches, alongside broader public health measures.In conclusion, the review emphasises the significant public health concern AF represents in Nigeria, especially among HF and stroke patients, and stresses the importance of tailored healthcare policies and interventions to mitigate AF's impact and improve patient outcomes.
