Abbreviations: AIx, augmentation index; cfPWV, carotid‐femoral pulse wave velocity; ET, ejection time; LVEF, left ventricular ejection fraction; PP, pulse pressure; SV, stroke volume; UT, upstroke time.
All analyses were adjusted for age, sex, black race, body mass index, and current smoking status. Coefficients represent change in pulse pressure per 1‐standard deviation change in the hemodynamic parameter.
