Difference between ejection times measured at two different peripheral locations as a novel marker of vascular stiffness
Subjects were divided into two groups according to their percentile rank of the ET index: group 1 had low ET index and group 2 had high ET index (A). Each graph showing the distribution of age (B), BMI (C), HR in supine (D), MAP supine (E), PWVΔPAT Toe-Finger supine (F), and ΔPWVStanding-Supine (G) in group 1 and group 2. Each graph represents the individual data points and superimposes a horizontal line at the arithmetic mean; error bars showing plus and minus one SD. ET: ejection time; BMI: body mass index; HR: heart rate; MAP: mean arterial pressure; PWV: pulse wave velocity; SD: standard deviation.
