PWVao: pulse wave velocity in the aorta; Aix brachial: brachial augmentation index; Aix aortic: aortic augmentation index; ED: duration of ejection from left ventricle; RT: return time; CSBP: central systolic blood pressure = systolic blood pressure in the aorta; Δc-bSBP: difference between central and brachial systolic blood pressure. DRA: diastolic reflection area.
