A cardiac event triggers an endocrine investigation: a case report of primary hyperaldosteronism revealed by postpartum cardiomyopathy

Hypertensive heart disease due to primary hyperaldosteronism as a cause of heart failure (HF) during pregnancy is a rare and challenging condition. This situation may be confused with other clinical entities, particularly with postpartum cardiomyopathy, a pregnancy-related pathology that is characterized by the development of HF secondary to left ventricular systolic dysfunction towards the end of pregnancy.

The case describes a 41-year-old female with severe preeclampsia, who presented for evaluation of severe congestive HF felt to be secondary to postpartum cardiomyopathy and was later diagnosed with primary hyperaldosteronism.

The report highlights the importance of considering endocrine disorders as potential aetiologies for HF in postpartum women.
