Increased ventricular compliance and reduced contractile function are observed in infants exposed to chorioamnionitis (109, 110).Histological chorioamnionitis is associated with:•Higher baseline fetal heart rate and increased periods of low variability (111).•Increased abundance of IL-1β and IL-6 in cord blood, increased heart rate, and decreased blood pressure in the first week post birth (76). This evidence concerns the gene IL6 and chorioamnionitis.
