A large study suggests that pregnant women who conceived with assisted reproductive technology (ART) were susceptible to more pregnancy and vascular complications on delivery.

The U.S. National Inpatient Sample (NIS) database revealed that hospital deliveries of babies conceived by ART, in comparison with spontaneous conception, had an independent association with maternal acute kidney injury (38 vs. 9 per 10,000 deliveries [adjusted OR 2.52]), maternal arrhythmia (143 vs. 74 per 10,000 deliveries [aOR 1.65]), placental abruption (200 vs. 107 per 10,000 deliveries [aOR 1.57]), cesarean delivery (5,489 vs. 3,211 per 10,000 deliveries [aOR 1.38]), and preterm birth (1,433 vs. 624 per 10,000 deliveries [aOR 1.26]). The obstetric and vascular complications were reported more often among women with cardiovascular disease (CVD) risk factors. The adverse obstetric and vascular outcomes linked to ART were noted in both singleton and multifetal pregnancies. The findings are published in the Journal of the American Heart Association… (Medpage Today)
