Summary of New Study Links Prenatal Depression to Heart Disease:
A recent study published in the Journal of the American Heart Association has found that individuals who experience depression during pregnancy have a higher risk of being diagnosed with the cardiovascular disease within two years postpartum. The study analyzed data from over 100,000 individuals who gave birth in Maine between 2007 and 2019 and found that individuals with prenatal depression had an increased risk of developing heart failure, ischemic heart disease, arrhythmia/cardiac arrest, cardiomyopathy, stroke, high blood pressure. The study also notes cardiovascular disease is the leading cause of pregnancy-related death in high-income countries, including the United States. The study emphasizes the importance of individuals being aware of their long-term cardiovascular health and implementing prevention strategies during pregnancy.

Prenatal Depression Linked to Higher Risk of Cardiovascular Disease Postpartum
A new study has found that individuals diagnosed with depression during pregnancy have a higher risk of developing cardiovascular disease within two years postpartum. The study emphasizes the importance of using pregnancy as a window to future health, recommending that those with prenatal depression be aware of their long-term cardiovascular health and implement prevention strategies.
Higher Likelihood of Cardiovascular Disease Diagnosis Postpartum
The study, published in the Journal of the American Heart Association, analyzed data from over 100,000 individuals who gave birth in Maine between 2007 and 2019. The research team aimed to estimate the cumulative risk of new cardiovascular disease diagnoses within two years after delivery and found that individuals who suffered from depression during pregnancy were more likely to be diagnosed with cardiovascular disease within two years postpartum.
Significant Association Between Depression and Ischemic Heart Disease
The most significant association was between depression and ischemic heart disease, with individuals with depression having an 83% higher risk of developing the condition than those without depression. The increased risk of cardiovascular disease was found even among individuals without high blood pressure during pregnancy.
Pregnancy as a Window to Future Health
“We need to use pregnancy as a window to future health,” said lead study author Christina M. Ackerman-Banks, M.D. “Complications during pregnancy, including prenatal depression, impact long-term cardiovascular health. The postpartum period provides an opportunity to counsel and screen people for cardiovascular disease to prevent these outcomes.”
Limited Investigation Into the Link Between Prenatal Depression and Cardiovascular Disease
Even though roughly 20% of people go through depression during pregnancy, there has been limited investigation into the link between prenatal depression and the increased risk of cardiovascular disease.
Implications and Recommendations
Cardiovascular disease is the leading cause of pregnancy-related death in high-income countries, including the U.S. The study authors recommend that anyone diagnosed with prenatal depression be aware of the implications on their long-term cardiovascular health, screen for other risk factors, and consult their primary care doctor to implement prevention strategies for cardiovascular disease.
Future Studies Needed
The authors acknowledge that while the study population was large, the results were based on medical claims data, meaning that diagnoses of conditions could not be confirmed. Additionally, race, ethnicity, and physical activity levels were unavailable. According to the authors, future studies testing interventions integrated into prenatal and postpartum care may help overcome these limitations and inform current recommendations.
