Samba H, et al. - Since data on the link between peripheral artery disease and mortality in sub-saharan Africa (SSA) is lacking, researchers evaluated the prognostic significance of the ankle brachial index (ABI) in older adults in the Republic of Congo. They performed a longitudinal population-based survey (EPIDEMCA-FU) involving Congolese patients ≥65 years. The link between an ABI≤0.90 and mortality was assessed using Cox proportional hazard models, adjusted for traditional and cardiovascular risk factors. An increased mortality risk among older subjects was predicted by a low ABI in this study. After adjustment, an increased risk of mortality correlated with an ABI≤0.90. ABI may afford a simple and cheap instrument to detect older people at high mortality risk in SSA. Increasing age, dementia, alcohol use, and female sex were also independently linked with mortality.
