Longitudinal maternal hemodynamics from late pregnancy to postpartum in uncomplicated twin pregnancies—A glimpse into long‐term cardiovascular risk?

Monochorionic twin pregnancies are characterized by elevated cardiac output and reduced vascular resistance in late pregnancy, with a similar hemodynamic pattern appearing to persist in the postpartum period. This persistent cardiovascular strain may underlie the elevated short-term cardiovascular risk observed after twin births. Our findings highlight the need for larger longitudinal studies to explore the transition from physiological adaptation to potential cardiovascular maladaptation.
