Spectrum of heart failure in sub-Saharan Africa: data from a tertiary hospital-based registry in the eastern center of Burkina Faso

Résumé fourni par la source

INTRODUCTION: Heart failure (HF) is a strong contributor to non-communicable diseases burden in sub-Saharan Africa (SSA). Few studies have addressed the pattern of HF in Burkina Faso. METHODS: December 2016 and followed up until June 2017. Primary outcome of interest was mortality. RESULTS: Overall 318 of 1805 cardiac cases presented with acute HF (17.62 %). Of the 298 patients included in the analysis process, 239 had de novo HF and 150 were male. The mean age was 58.56 ± 18.54 years. Eighty-eight patients presented with atrial fibrillation. The mean left ventricular ejection fraction (LVEF) was 38.20 ± 12.85 % with reduced ejection fraction (LVEF < 40%) accounting for 59.73% of the cases. Most of the study patients lived in rural areas. Hypertensive heart disease (50.34%) and idiopathic dilated cardiomyopathy (19.80%) were the leading causes of HF. Most patients received renin-angiotensin system blockers contrasting with a lower prescription rate of beta-blockers (99% versus 18.79% respectively). The incidence of all-cause mortality was 31 percent patients-years. CONCLUSION: Heart failure is frequent in SSA, affecting patients at younger age. Predominantly of non-ischemic cause, commonly hypertensive, the disease is associated with high mortality.
