Aging and changes in the pulse wave 15. Central Pressure shows the effects of Drug therapy masked by31 In the CAFE study of over 2,000patients, brachial bloodpressure was controlled in bothstudy arms But the ACE/ CCB arm had uplower central BP and 30% lessCV events than the beta blockerarm. Augmented Pressure wasreduced by the ACE/ CCB butnot by the beta blocker. Brachial pressure does notmeasure arterial stiffnessBrachial PressureWilliams B et al., Circulation 2006; 113: 1213-25 16.
