Gibbone E, Wright A, Campos RV, et al. - Researchers performed this prospective observational study to compare pregnancies that develop gestational diabetes mellitus (GDM) vs those without GDM in order to determine disparities in maternal cardiovascular indices at 19‐23 weeks’ gestation between them. They investigated if such cardiovascular alterations resulted from maternal demographic features and medical history or the GDM per se. Women visiting for a routine hospital visit at 19⁺¹ ‐ 23⁺³ weeks’ gestation were included. Findings revealed the presence of subtle functional and hemodynamic cardiac alterations before GDM development, in women with GDM. These cardiac alterations were mostly associated with the adverse risk factor profile of these females. No additional predictive information for GDM development in pregnancy was conferred by maternal cardiac evaluation at 20 week compared with information offered by demographic features and medical history.
