New research reveals that non-Hispanic Black mothers are more than three times as likely as white mothers to develop peripartum cardiomyopathy—a rare but life-threatening form of heart failure that strikes during late pregnancy or shortly after delivery. The study, based on over 7 million births in California, found that this disparity persists even after adjusting for socioeconomic status, neighborhood conditions, and chronic high blood pressure.
“This study highlights that even after adjusting for socioeconomic status and high blood pressure, the risk for Black mothers remains significantly elevated,” said Jacquelyn Y. Taylor, associate editor of the Journal of the American Heart Association. Lead author Curisa M. Tucker emphasized that “Black mothers and mothers in underserved communities face the highest risks, pointing to deep-rooted inequities in health care and living conditions.”
Barriers such as limited access to prenatal and postpartum care, transportation challenges, and environmental stressors like pollution and unsafe housing may delay diagnosis and treatment. These stressors, Tucker noted, can contribute to chronic stress, which negatively impacts cardiovascular health.
The study found that most cases of peripartum cardiomyopathy were diagnosed after hospital discharge, underscoring the need for better postpartum follow-up. “Access to postpartum care is crucial,” Taylor said, especially since symptoms like chest pain, swelling, or shortness of breath may signal serious complications.
The findings call for urgent attention to systemic inequities and improved maternal care to protect Black mothers from preventable heart failure.
