Central blood pressure:
what do we really know today?
Significant and highly variable differencebetween aortic and brachial systolic pressure at all ages
Published online: Eur Heart J. 2014;doi:10.1093/eurheartj/eht565.
Difference between brachial and aortic systolic blood pressure (SphygmoCor) in healthy men (dark blue bars;n=2779) and women (light blue bars; n=2869). The data represent means plus standard deviation.
Techniques for assessing central blood pressure
(A) Invasive cardiac catheterization; (B) direct applanation tonometry of the carotid artery; (C) applanation tonometry of the radial artery; (D) cuff-based oscillometry at the brachial artery.

Predictive value of central pressure has been investigated in a variety of patient cohorts

Carotid PP
All-cause (including CV mortality)
Carotid PP but not carotid SBP or brachial SBP/PP remained independently associated with all-cause mortality after adjustment. Not mutually adjusted for brachial pressure.

CV mortality and events
Carotid SBP and PP independently associated with cardiovascular events and carotid SBP with fatal cardiovascular events. Association remained after adjusting for brachial BP.

All-cause and CV mortality
Only carotid SBP predicted CV mortality after adjustment. No adjustment for brachial pressure.

ASCOT trial: difference in central aortic pressure is an important explanation for better outcomes in amlodipine-perindopril regimen
Williams B, Lacy PS, Thom SM, et al. Circulation. 2006;113:1213-1225.
“By demonstrating that amlodipine-perindopril therapy is associated with substantially lower central aortic pressure than atenolol-thiazide therapy, the results of the CAFE study provide a plausible and novel
mechanism to explain the effects of the different treatment arms in ASCOT.”
