Key result
High brachial-ankle pulse wave velocity (>22.63 m/s) in acute stroke patients was associated with increased risks of all-cause (HR 1.97; 95% CI 1.25–3.08) and vascular mortality (HR 2.39).

Does high brachial-ankle pulse wave velocity predict mortality in patients with acute ischemic stroke?
Hazard Ratio: 1.97 (95% CI 1.25–3.08)
Measurement of brachial-ankle pulse wave velocity during the acute phase of ischemic stroke is a strong predictor of long-term all-cause and vascular mortality.
Kim et al. (2014) conducted a cohort in acute ischemic stroke (n=1,765). High brachial-ankle pulse wave velocity (>22.63 m/s) vs. Low brachial-ankle pulse wave velocity (<17.79 m/s) was evaluated on all-cause mortality (HR 1.97, 95% CI 1.25-3.08). High brachial-ankle pulse wave velocity (>22.63 m/s) in acute stroke patients was associated with increased risks of all-cause (HR 1.97; 95% CI 1.25–3.08) and vascular mortality (HR 2.39).
