Heart Failure in Pregnancy: Early Detection Saves Lives, Says New AHA Statement

A new scientific statement from the American Heart Association, published in Circulation, emphasizes that early detection and timely treatment of heart failure in pregnant and postpartum women are crucial to prevent serious complications like irregular heartbeat, stroke, and death. The statement, “Heart Failure Occurring in the Perinatal Period,” highlights that nearly 1 in 4 women aged 20-44 currently has some form of cardiovascular disease, and heart disease is a leading cause of pregnancy-related death in the U.S. The challenges are compounded because heart failure symptoms—shortness of breath, fatigue, swelling—often mimic normal pregnancy experiences, delaying diagnosis and treatment.

Key risk factors include high blood pressure, Type 2 diabetes, obesity, and unique perinatal factors like older maternal age, multiple gestation, and use of assisted reproductive technology. Significant disparities exist: Black adults have a 19% higher risk of developing heart failure, and Black and Native American women are more frequently diagnosed with peripartum cardiomyopathy (PPCM). Heart failure contributed to 14.5% of pregnancy-related deaths among American Indian/Alaska Native women and 14.2% among Black women. The statement calls for standardized screening, prompt treatment, and coordinated care between obstetricians and heart specialists, particularly during the first year postpartum, a high-risk period.

The writing group, led by Dr. Demilade A. Adedinsewo of the Mayo Clinic, stresses that a multidisciplinary cardio-obstetrics team is vital for continuous monitoring. Management includes medications like beta blockers and diuretics, and lifestyle changes following Life’s Essential 8 metrics. The statement also underscores the importance of ongoing postpartum care beyond the traditional six-week checkup, including telemedicine and home visits. By recognizing symptoms earlier and initiating appropriate care, clinicians can prevent life-threatening outcomes and save mothers’ lives.
