Cox proportional hazards models for individual pulsatile hemodynamic measures as predictors of a major cardiovascular event during the follow-up period.

Hemodynamic measure Hazard Ratio (LCI,UCI) P
Carotid-femoral (aortic) pulse wave velocity 1.48 (1.16, 1.91) 0.002
Carotid-radial (muscular artery) pulse wave velocity 1.07 (0.92, 1.25) 0.77
Augmentation index 0.91 (0.77, 1.07) 0.24
Central pulse pressure 1.00 (0.99, 1.01) 0.98
Pulse pressure amplification 0.86 (0.19, 3.82) 0.84

HR, hazard ratio; LCI, UCI, lower and upper 95% confidence intervals; CVD, cardiovascular disease. Hazard ratios expressed per 1 SD higher value, adjusted for age, sex, total cholesterol, HDL cholesterol, systolic blood pressure, smoking, diabetes and hypertension treatment. For carotid-femoral pulse wave velocity, the inverse transform was used and results were expressed per 1 SD lower inverse values (which corresponds to higher pulse wave velocity).
