Abstract
OBJECTIVES: The objective of this study was to investigate whether oscillometric AS measurements are different in pregnant women with and without preeclampsia (PE). STUDY DESIGN: = 46) between 2014 and 2019. In the case group, pregnancies complicated by PE were classified as either early-onset (<34 weeks of gestation) or late-onset (≥34 weeks of gestation) PE and subgroup analysis was performed. MAIN OUTCOME MEASURES: Pulse wave velocity (PWV), augmentation index (Alx), and Alx at a heart rate of 75 beats per minute (Alx-75) were measured using a brachial cuff-based automatic oscillometric device (Mobil-O-Graph 24 h PWA). RESULTS: = .009). There was no significant difference in Alx in either of the analyses. CONCLUSIONS: PWV and Alx-75 are higher in pregnancies complicated by PE, in comparison with normotensive pregnancies, as well as in early-onset PE, in comparison with late-onset PE.Key messagesPulse wave velocity is higher in pregnancies complicated by preeclampsia.Augmentation index at a heart rate of 75 beats per minute is higher in pregnancies complicated by preeclampsia.Arterial stiffness assessment is a promising risk-stratification tool for future cardiovascular complications but further studies are required.
