Background: Arterial stiffening potentially plays a role in cardiac hypertrophy. We recently demonstrated in patients that arterial stiffness can be substantially pressure dependent and, here, introduce a non-invasive measure to quantify the pressure dependence in the carotid artery, defined as the difference between systolic and diastolic pulse wave velocity (PWVdiff). Both PWVdiff and peripheral wave reflections (quantified by augmentation index, AIx) are biomechanically related to (late) systolic pressure increase. Therefore, we investigated the associations of PWVdiff and AIx with left ventricular mass index (LVMI).

Methods and Results: In 1522 subjects of the Asklepios cohort (age 35‑55 yrs, healthy) PWVdiff was calculated from segmental distensibility coefficients, as obtained by carotid artery ultrasound and tonometry (Figure). PWVdiff ranged from 0.7 to 4.4 m/s. Linear regression analysis showed a significant association of PWVdiff with LVMI (β of 1.26 g/m2.7 per m/s, 95% CI: 0.91–1.62), which remained significant after adjusting for covariates (p=0.03). AIx showed no consistent association with LVMI.

Conclusions: Carotid PWVdiff is independently associated with left ventricular mass index in presumed healthy middle-aged subjects. Non-invasive carotid artery ultrasound and tonometry enable assessment of the contribution of pressure dependent stiffness to LV pressure load, independently of wave reflections.
