“…Future researchers could apply FDA to investigate patterns of variation in other indices of maternal cardiovascular function that are commonly assessed in clinical and/or research settings (e.g. cardiac output, systemic vascular resistance, mean arterial pressure, pulse wave velocity, and uterine artery resistance [35][36][37][38][39][40]), or explore how two cardiovascular measures covary across pregnancy [16]. It would also be beneficial to include, if possible, observations of maternal pregravid blood pressure to examine how the cardiovascular system changes in the early stages of pregnancy.…”

Background: Research has revealed group-level differences in maternal blood pressure trajectories across pregnancy. These trajectories are typically constructed using clinical blood pressure data and multivariate statistical methods that are prone to bias and ignore the functional, dynamic process underlying a single blood pressure observation. The aim of this study was to use functional data analysis to explore blood pressure variation across pregnancy, and multivariate methods to examine whether trajectories are related to gestational age at birth. Methods: Clinical blood pressure observations were available from 370 women who participated in a longitudinal pregnancy cohort study conducted in Montreal, Quebec, Canada. Functional data analysis was used to smooth blood pressure data and then to conduct a functional principal component analysis to examine predominant modes of variation.Results: Three eigenfunctions explained greater than 95% of the total variance in blood pressure. The first accounted for approximately 80% of the variance and was characterized by a prolonged-decrease trajectory in blood pressure; the second explained 10% of the variance and captured a late-increase trajectory; and the third accounted for approximately 7% of the variance and captured a mid-decrease trajectory. The prolongeddecrease trajectory of blood pressure was associated with older, and late-increase with younger gestational age at birth. Conclusion:Functional data analysis is a useful method to model repeated maternal blood pressure observations and many other time-related cardiovascular processes. Results add to previous research investigating blood pressure trajectories across pregnancy through identification of additional, potentially clinically important modes of variation that are associated with gestational age at birth.

A quantitative investigation of hemodynamic adaptation to pregnancy using uterine artery Doppler ultrasonography and finger photoplethysmography

Abstract: The results of this study revealed clear relationship between UtA RI and PPG RI throughout pregnancy which could be exploited to enhance the potential ability in early recognition of pathophysiologic process in maternal adaptation and prediction of complicated pregnancy.
