Figure 1

Aortic pulse wave of a control group participant (top) and a cystic fibrosis group participant (bottom). P1 = first systolic peak. P2 = second systolic peak. Pf = forward or ejection wave. Pb = backward or reflexion wave. cSBP and cDBP = central systolicc and diastolic blood pressure. cPP = central pulse pressure. The AIx@75, the augmentation pressure (P2−P1), and the coefficient of reflection (Pb/Pf) are higher in the patient with cystic fibrosis. AIx@75 = (P2 − P1) / cPP *100 normalized for a heart rate of 75 bpm.
