Objective: Non-invasive measures of common carotid artery properties, such as diameter and distension, and pulse pressure, have been widely used to determine carotid artery distensibility coefficient – a measure of carotid stiffness (stiffness 1/distensibility coefficient). Carotid stiffness has been associated with incident cardiovascular disease (CVD) and may therefore be a useful intermediate marker for CVD. We aimed to establish age and sex-specific reference intervals of carotid stiffness.

Methods: We combined data on 22 708 individuals (age range 15–99 years, 54% men) from 24 research centres worldwide. Individuals without CVD and established cardiovascular risk factors constituted a healthy subpopulation (n ¼ 3601, 48% men) and were used to establish sex-specific equations for percentiles of carotid distensibility coefficient across age.

Results: In the sub-population without CVD and treatment (n ¼ 12 906, 52% men), carotid distensibility coefficient Z-scores based on these percentile equations were independently and negatively associated, in men and women, respectively, with diabetes {0.28 [95% confidence interval (CI) 0.41; 0.15] and 0.27 (0.43; 0.12)}, mean arterial pressure [0.26 (0.29; 0.24)
and 0.32 (0.35; 0.29)], total-to-high-density lipoprotein cholesterol ratio [0.05 (0.09; 0.02) and 0.05 (0.11; 0.01)] and BMI [0.06 (0.09; 0.04) and 0.05 (0.08; 0.02)], whereas these were positively associated with smoking [0.30 (0.24; 0.36) and 0.24 (0.18; 0.31)].

Conclusions: We estimated age and sex-specific percentiles of carotid stiffness in a healthy population and assessed the association between cardiovascular risk factors and carotid distensibility coefficient Z-scores, which enables comparison of carotid stiffness values between (patient) groups with different cardiovascular risk profiles, helping interpretation of such measures.
