Brachial-ankle PWV for predicting clinical outcomes in patients with acute stroke

Abstract

Background: Although brachial-ankle pulse wave velocity (baPWV) is well-known for predicting the cardiovascular mortality and morbidity, its anticipated value is not demonstrated well concerning acute stroke. Methods: Total 1557 patients with acute stroke who performed baPWV were enrolled. We evaluated the prognostic value of baPWV predicting all-cause death and vascular death in patients with acute stroke Results: Highest quartile of baPWV was ≥23.64 m/s. All-caused deaths (including vascular death; 71) were 109 patients during follow-up periods (median 905 days). Multivariate Cox regression analysis revealed that patients with the highest quartile of baPWV had higher risk for vascular death when they are compared with patients with all other three quartiles of baPWV (Hazard ratio with 95% confidence interval [CI] 1.879 [1.022–3.456], p = .042 for vascular death). Conclusion: High baPWV was a strong prognostic value of vascular death in patients with acute stroke
