Brachial-ankle pulse wave velocity (baPWV) is widely used as a marker of arterial stiffness, but there are no data regarding the usefulness of measuring baPWV in hypertensive patients after stroke. The purpose of this study was to examine the clinical significance of baPWV by assessing its correlation with echocardiographic parameters in hypertensive patients after stroke. The study enrolled 61 hypertensives after stroke (24 patients with cerebral infarction and 37 with cerebral hemorrhage) and 61 age-matched hypertensives without stroke. Left ventricular (LV) hypertrophy was evaluated by measuring LV mass index (LVMI) and relative wall thickness (RWT), and LV diastolic function was evaluated by measuring peak early mitral annular velocities (E') using echocardiography. Concentric LV hypertrophy showing increased RWT (0.50 +/- 0.12) was observed in hypertensives after stroke, but not in hypertensives without stroke. In hypertensives after stroke, elevated baPWV correlated with age (r = 0.60, p &lt; 0.001), systolic blood pressure (r = 0.56, p &lt; 0.001), increased LVMI (r = 0.47, p &lt; 0.001), and decreased E' (r = -0.40, p = 0.002). Multiple regression analysis showed that age (beta coefficient = 0.43, p &lt; 0.001), systolic blood pressure (beta coefficient = 0.40, p &lt; 0.001), and LVMI (beta coefficient = 0.25, p = 0.008) were independent determinants of elevated baPWV. In conclusion, elevated baPWV is more closely associated with LV hypertrophy than with LV diastolic dysfunction. Elevated baPWV is independently associated with the severity of LV hypertrophy adjusted with systolic blood pressure and age in hypertensive patients after stroke.
