Results of the pAI showed lower reproducibility. Oscillometric arterial stiffness measurement by CAVI and baPWV has proved to be highly reproducible in Caucasians. Bland-Altman plots showed no particular dispersion patterns except for pAI. The mixed linear model revealed that 68.7%/80.1%/55.0% of the CAVI/baPWV/pAI variance was accounted for by the subject, 5.2%/8.1%/ < 0.01% by the fieldworker, 6.7%/7.8%/28.5% by variation between measurement days, and 19.4%/4%/16.5% by measurement error. ![]() The intraclass correlation coefficient ranged from 0.6 for pAI to 0.8 for CAVI, and 0.9 for baPWV. The mean coefficient of variation for CAVI was 4.4%, baPWV 3.9%, and pAI 7.4%. CAVI, baPWV and pAI were measured twice within 90 days in a representative subsample ( n = 105) of SAPALDIA 3 with a mean age of 63 years (52.4% female). ![]() We assessed reproducibility of the cuff-based arterial stiffness measures cardio-ankle vascular index (CAVI), brachial-ankle pulse wave velocity (baPWV) and peripheral augmentation index (pAI) in a subsample of the second follow-up of the Swiss Cohort Study on Air Pollution and Lung and Heart Diseases in Adults (SAPALDIA 3). ![]() There is an increasing interest in oscillometric arterial stiffness measurement for cardiovascular risk stratification. ![]()
