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

Abstract

Background: 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. Case summary: 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. Discussion: The report highlights the importance of considering endocrine disorders as potential aetiologies for HF in postpartum women.
