Correlation between central and uterine hemodynamics in hypertensive disorders of pregnancy

ABSTRACT Objective Pregnancies affected by a hypertensive disorder (HDP) have increased uterine artery pulsatility index (UtA‐PI) compared with that in healthy pregnancies. Women with HDP are also known to have lower cardiac output and increased systemic vascular resistance. The aim of this study wa...

Zusammenfassung:	ABSTRACT Objective Pregnancies affected by a hypertensive disorder (HDP) have increased uterine artery pulsatility index (UtA‐PI) compared with that in healthy pregnancies. Women with HDP are also known to have lower cardiac output and increased systemic vascular resistance. The aim of this study was to investigate the relationship between central and uterine hemodynamics in HDP and uncomplicated pregnancy. Methods This was a prospective study of HDP and normotensive control singleton pregnancies presenting at a tertiary referral hospital between January 2012 and December 2017. Paired measurements of maternal hemodynamics, using a non‐invasive device (USCOM‐1A®), and UtA‐PI were performed in the third trimester. HDP pregnancies were divided into preterm (onset
