HTR2B and myocardial infarction: Given our consistent findings of reduced ventricular size, 5‐HT2B expression and cardiac function with perinatal exposure across animal models (Haskell et al., 2017; Kent et al., 2022; Lu et al., 2024), we sought to determine if this small heart phenotype from perinatal sertraline exposure would impact post‐MI outcomes utilizing a physiologically relevant whole pregnancy model and if sex would influence outcomes.
