Carotid-Femoral Pulse Wave Velocity (cfPWV)
Non-invasive applanation tonometry measurement of the propagation speed of the arterial pressure wave along the aorta.
Standard vs. Optimal Reference Rangesm/s
Standard reference intervals represent the statistical 95% distribution of unselected commercial populations. Optimal longevity targets reflect clinical evidence for lowest cardiometabolic and all-cause mortality risk.
Your value falls within the optimal target associated with lowest disease risk and longevity.
<10.0 m/s (age-adjusted)
General reference distribution across unselected commercial populations.
<7.5 m/s
Concentration target associated with minimal all-cause cardiometabolic mortality.
Molecular Mechanism & Clinical Purpose
Reflects structural elastin fragmentation, collagen cross-linking, and vascular medial calcification in the aorta.
Differential Diagnosis
Elevated Levels (cfPWV High)
- •Advanced aortic arterial stiffness (>10 m/s)
- •Isolated systolic hypertension
- •End-stage renal disease
- •Vascular aging
Low Levels (cfPWV Low)
- •Optimal arterial compliance and elastic recoil
- •Youthful vascular wall architecture

Pre-Analytical Caveats & Diagnostic Workup
Pre-Analytical Considerations:
Specimen collection should follow standardized phlebotomy protocols. Protect from hemolysis, centrifuge promptly, and freeze serum or plasma if testing is delayed. Patient should be in a resting, fasting state where indicated.
Reflexive Testing Protocol:
- Confirmatory testing and secondary biomarker quantification for cfPWV
- Targeted organ system imaging or functional dynamic testing related to aortic arterial stiffness
- Comprehensive baseline metabolic, renal, and inflammatory assessment (CMP, CBC, hs-CRP)
