Introduction: This study aims to explore the burden of cardiovascular disease (CVD) and associated risk factors in Sub-Saharan Africa (SSA) using data from the Global Burden of Disease (GBD).

Hypothesis: That the burden of CVD has increased in SSA over time, and there are associated risk factors contributing to this burden.

Methods: We analyzed CVD prevalence, mortality, and incidence in 46 SSA countries using Bayesian regression, demographic methodologies, and mortality-to-incidence ratios. Disability-adjusted life years (DALYs) were calculated, and risk factors were assessed through the comparative risk assessment framework of the GBD.

Results: Between 1990 and 2019, CVD prevalence in SSA increased by 131.7%, with a modest rise of 2.1% in age-standardized prevalence rates. Ischemic heart disease, stroke (CVA), and rheumatic heart disease were the most prevalent conditions. CVD deaths increased from 564,140 to 1,003,893, with a 14.4% decrease in death rates. Non-rheumatic valvular disease showed a significant increase. DALYs increased by 68.4%, but some CVDs saw decreases in DALY rates.

Conclusions: Despite rising CVD prevalence in SSA, age-standardized rates only modestly increased. However, the persistently high burden, increasing non-rheumatic valvular disease, and rising DALYs highlight challenges in prevention and management. These findings highlight the persistent challenge of CVD in SSA and emphasize the need for continued efforts in prevention and management strategies to address the growing burden of CVD in this region.
