The left panel illustrates tonometrically measured radial artery wave form obtained from a patient prior to CABG surgery upper panel and a healthy volunteer lower panel.
The right panels show derived aortic waveforms.
The augmentation index is calculated as the quotient of the difference between systolic blood pressure and the pressure measured at the inflection point of the waveform over the pulse pressure. In normal vessels lower panel the augmented pressure resulting from reflected waves is small in magnitude and occurs during diastole. In contrast, in stiff vessels upper panel , the augmented pressure is amplified and occurs during systole, resulting in increased pulsatile load in the cardiovascular system. Brain Protection in Cardiac Surgery. Relationship between pulse pressure and probability for stroke in a series of patients after cardiac surgery.

There was a significant relationship between rising pulse pressure and risk for perioperative stroke. In a Cox model, pulse pressure was an independent predictor of stroke hazard ratio, 1. Hypertension ;—5.
