AI Insight
The Sub-Saharan Africa Survey of Heart Failure (THESUS-HF) conducted over 15 years ago provided the first major prospective, multinational characterization of acute heart failure in sub-Saharan Africa. The study revealed that African patients with acute heart failure were significantly younger than typical Western populations, affected men and women almost equally, and primarily suffered from non-ischaemic causes, particularly hypertensive and rheumatic heart diseases rather than coronary artery disease. Despite these distinct etiological patterns, patients experienced poor short-term outcomes.
Why it matters
This research established that heart failure in Africa represents a clinically distinct entity with different demographic patterns, risk factors, and causes compared to high-income countries, requiring region-specific prevention and treatment strategies. The findings highlighted the need for healthcare systems in sub-Saharan Africa to prioritize hypertension control and rheumatic heart disease prevention rather than primarily focusing on ischaemic heart disease interventions designed for Western populations.
Understand the Science
More than 15 years ago, the original Sub-Saharan Africa Survey of Heart Failure (THESUS-HF) provided one of the first prospective, multinational descriptions of acute heart failure in sub-Saharan Africa.1 THESUS-HF found that patients with acute heart failure in sub-Saharan Africa were young, with near-equal incidence in men and women, that incidence was driven overwhelmingly by non-ischaemic disease, especially hypertensive and rheumatic heart diseases, and that short-term prognosis was poor.1 The study reframed heart failure in Africa as a distinct clinical entity rather than a footnote to high-income cohorts.
