Central hemodynamics are associated with fetal outcomes in pregnancies of advanced maternal age

Abstract Objectives Age is a known risk factor for both maternal cardiovascular disease and adverse outcomes in pregnancy. We aimed to characterize the hemodynamic profiles in pregnancies of advanced maternal age (AMA) and correlate these with fetal outcomes. Study Design This was a prospective observational study of pregnancies undergoing antenatal testing. Maternal hemodynamics were measured non-invasively using an imaging probe at the descending aorta and the Uscom BP+ arm cuff utilizing pulse pressure wave analysis. The Wilcoxon rank-sum test, Fisher’s exact test, and Spearman rank correlation test were used for statistical analysis in R. Main Outcome Measures Hemodynamic measurements, neonatal birthweight Results Twenty-one AMA and twenty-four control patients were enrolled. Mean age ± SD was 39 ± 3.22 in the AMA cohort and 28 ± 4.32 in the control cohort (p Conclusions Hemodynamic alterations consistent with a low output, high resistance cardiovascular circuit were associated with lower birthweight in AMA, but not in control pregnancies.
