Do central haemodynamic indexes predict future cardiovascular events and all-cause mortality independently of or better than peripheral pressures?
Central haemodynamic indexes, particularly augmentation index, are independent predictors of cardiovascular events and mortality, though central pulse pressure is not significantly better than peripheral pulse pressure for risk prediction.
Central haemodynamic indexes are independent predictors of future CV events and all-cause mortality. Augmentation index predicts clinical events independently of peripheral pressures, while central PP has a marginally but not significantly (P = 0.057) better predictive ability when compared with peripheral PP.
Vlachopoulos et al. (2010) studied this question.
