Abstract/OtherAbstract:
AIMS: To assess and compare reactive hyperemia-related changes in PWVcr and FMD in pregnant women (healthy and with hypertensive disorders) and non pregnant women.
METHODS: Healthy pregnant (HP; n=13), preeclamptic (PE; n=7), non-proteinuric hypertensive (NPH; n=6) and non-pregnant (NP; n=32) women were included. Left PWVcr (strain gauge mechano-transducers), left brachial arterial diameter (B-Mode ultrasound) and blood flow velocity (Doppler ultrasound) were measured before (baseline) and after the transient ischemia of the left forearm were determined.
RESULTS: One minute after the cuff deflation, PWVcr decreased in HP (6.9 ± 1.5 to 6.0 ± 0.9 m/s, p<0.001) and in NP (8.1 ± 0.9 to 7.4 ± 0.9 m/s; p<0.001). NPH showed a blunted hyperemic PWVcr response (6.6 ± 1.4 to 6.7 ± 1.0 m/s; p=0.91), whereas PE showed a tendency to increase (6.0 ± 0.7 to 6.4 ± 0.8 m/s; p=0.10). Reactive hyperemia PWVcr response (ΔPWVcr in %) differed comparing HP with NPH (-12% vs. +2%; p<0.01) and with PE (-12 vs. +6%; p <0.01), whereas no differences were found between NHP and PE (p=1.00).
CONCLUSION: HP showed an enhanced PWVcr reduction, whereas PE and NPH showed a blunted hyperemic PWVcr response. Carotid-radial PWVcr analysis could have a potential role in the assessment of pregnancy to study EF with a potential clinical application in predicting pregnancy induced hypertension and preeclampsia.
