Why the study?

Can radial late-SBP (rSBP2) measured by noninvasive devices accurately estimate central SBP in clinical practice?

Population

106 patients from a cardiovascular department, mean age 57.5±14.1 years

Comparison

Estimation of central SBP using radial late-SBP… vs Carotid SBP (cSBP) and aortic SBP (aSBP)

Design

Cross-sectional

Overview

Radial late-SBP underestimates central SBP; cross-sectional data leave open its reliability for precise noninvasive estimation in practice.

Structured PICO

Can radial late-SBP (rSBP2) measured by noninvasive devices accurately estimate central SBP in clinical practice?

P
Population
106 patients from a cardiovascular department, mean age 57.5±14.1 years
I
Intervention
Estimation of central SBP using radial late-SBP (rSBP2) measured by noninvasive tonometry-based devices (SphygmoCor and PulsePen)
C
Comparator
Carotid SBP (cSBP) and aortic SBP (aSBP)
O
Outcome
Agreement and discrepancy between rSBP2 and central SBP (aSBP and cSBP)surrogate

Noninvasive devices using radial late-SBP significantly underestimate central SBP and cannot be applied for precise estimation in clinical practice.
