Individuals born to mothers who experienced placental abruption during pregnancy face substantially higher risks of developing cardiovascular disease and dying from cardiovascular events by age 28 compared to those whose births did not involve this complication. According to research published in the Journal of the American Heart Association, these individuals are approximately 4.6 times more likely to die from cardiovascular disease and nearly three times more likely to be hospitalized for heart-related conditions during their first 28 years of life.
The study analyzed nearly 3 million births in New Jersey from 1993 to 2020, finding that approximately 1% of pregnancies (28,641) involved placental abruption, a condition where the placenta separates from the uterus before delivery rather than after birth. During a 28-year follow-up period, children born to mothers with placental abruption showed significantly elevated cardiovascular risks compared to those born without this complication. The risk of stroke hospitalization was 2.4 times higher for these children, and cardiovascular risks were even more pronounced among infants younger than one year old.
"Our study suggests that placental abruption needs to be taken as a very serious complication for the mother and also potentially affecting the baby's cardiovascular health later in life," said study lead author Cande Ananth, Ph.D., M.P.H., of Rutgers Robert Wood Johnson Medical School. "Most treatments after a placental abruption focus on following the mother after a pregnancy complication. Our study shows it is important that their children are also monitored to identify potential complications due to their increased risk of cardiovascular disease."
The research findings indicate that the association between placental abruption and increased cardiovascular risk persisted even when comparing biological siblings, suggesting that genetic and environmental factors alone do not explain this relationship. This reinforces the need for specific monitoring of children exposed to this pregnancy complication. According to the American Heart Association's 2026 Heart Disease and Stroke Statistics, placental abruption occurs in 0.5% to 1% of the general population, making it a significant public health concern.
Health implications extend beyond immediate pregnancy outcomes. "We know that women who have complications during pregnancy are often at higher risk for heart disease and stroke, and that's why the American Heart Association recommends closely monitoring these women, especially in the first three months to a year after birth," said Stacey E. Rosen, M.D., FAHA, volunteer president of the American Heart Association. "The findings of this study reinforce that it is also important to monitor their babies for risks and identify opportunities to reduce the potential impact these complications may have on them not only right after birth, but throughout their lifetime."
The study authors note that placental abruption is a sudden event that cannot be prevented and comes with no warning, though certain factors increase risk, including advanced maternal age and multiple pregnancies. They emphasize the importance of maintaining healthy lifestyles during pregnancy, including avoiding smoking, alcohol, and illegal drugs like cocaine, as well as maintaining good blood pressure control, since these factors are linked to placental abruption. More research is needed to understand the mechanisms through which placental abruption affects long-term cardiovascular health in offspring.
This retrospective analysis, part of the Placental Abruption and Cardiovascular Event Risk (PACER) project, represents one of the first studies to establish this link, though researchers caution that the observational nature of the study means it cannot prove cause and effect.
