A conversation with cardiologist Zainab Mahmoud (Links to an external site)
Born and raised in Nigeria, Mahmoud has built a career spanning the United States and her home country, combining clinical care with research to improve cardiovascular health during and after pregnancy worldwide. Pregnancy places significant strain on the cardiovascular system. It can trigger or worsen conditions such as heart failure and high blood pressure, sometimes leading to preeclampsia, a serious pregnancy complication characterized by sudden high blood pressure and organ damage. These complications can threaten the health of both mother and baby, and what happens during pregnancy can also shape a woman’s cardiovascular health long after she gives birth.

From Nurse to Patient: How a Rare Heart Condition Changed Abigail Ellis’ Life (Links to an external site)
When Abigail Ellis began working as a cardiothoracic surgery nurse at Barnes-Jewish Hospital, she was beginning the career she had trained for—helping patients recover from complex heart procedures.
She never expected to become one of them.
In early 2025, Abigail began experiencing chest pain, shortness of breath, and fatigue. At the time, she was finishing nursing school and assumed stress and anxiety were to blame.
Fellow Vijay selected for inaugural ACC Fuster Prevention Forum
Aishwarya Vijay, MD, a research fellow with the WashU Cardiovascular Division, has been selected for the American College of Cardiology’s inaugural cohort for the Fuster Prevention Forum. Participants will become experts in primordial prevention and gain skills to lead a culture of prevention in their local communities.
