Moving the Needle in Medicine: Blazing a Trail in Cardiology, with Martha Gulati, MD, MS

A physician's career path is rarely linear and the influences shaping it are seldom predictable. In the inaugural episode of 

, host Alex Hajduczok, MD, a cardiologist and heart failure specialist at Oklahoma Heart Institute, sits down with Martha Gulati, MD, MS, FACC, FAHA, director of the Davis Women's Heart Center at Houston Methodist and one of the most recognized voices in women's cardiovascular health. 

The conversation spans 5 decades of professional formation, from a childhood in Ontario marked by early loss to a career defined by landmark research, guideline leadership, and an enduring commitment to a population long underserved by cardiology. Gulati traces her interest in medicine to her mother, a physicist who was once steered away from medicine because it was considered a male field, and to the early death of a parent under a physician's missed diagnosis. 

Her path toward cardiology solidified in medical school at the University of Toronto, where a mentor's invitation into the catheterization laboratory proved decisive. That same thread of mentorship runs throughout the conversation: Gulati credits a series of physicians, including the late Morton Arnsdorf at the University of Chicago and Len Sternberg in Toronto, with not only opening professional doors but shaping how she thinks about sponsorship, advocacy, and the responsibility of those in senior roles to invest in the careers of others.

The episode's most substantive clinical territory covers the origins of Gulati's expertise in women's cardiovascular disease. A lecture by Nanette Wenger, MD, delivered when Gulati was a medical student crystallized the field's foundational failure: women had been systematically excluded from the studies informing cardiovascular care. Rather than accepting this as background knowledge, Gulati made it the organizing principle of her career. She pursued epidemiological training at the University of Chicago, earned a master's degree in health sciences, and published foundational work on exercise capacity in women using the Woman's Take Heart dataset, work appearing first in Circulation and subsequently in the New England Journal of Medicine. 

That body of research established both her scientific identity and a clinical platform she has continued to build across appointments at Ohio State University, Cedars-Sinai Medical Center, and now Houston Methodist. Gulati also discusses her experience leading the 2021 ACC/AHA Chest Pain Guidelines the first such guideline ever developed, as chair of the writing committee, a role she accepted without prior guideline experience. 

She describes the political complexity inherent in evidence synthesis when imaging specialties have competing stakes, the iterative nature of responding to thousands of reviewer comments, and the personal satisfaction of successfully incorporating guidance on ischemia with non-obstructive coronary arteries (INOCA) into the final document. The conversation closes with a frank exchange on GLP-1 receptor agonists and their implications for preventive cardiology, physician wellness, and the structural barriers keeping high-cost medications from patients who need them most.
