Stanford cardiologist Celina M. Yong is redefining what leadership in medicine looks like.
It’s just past midnight in a cardiac catheterization lab.
Fluorescent lights hum overhead as a blocked coronary artery appears on the monitor. A team moves quickly with precision. Every second counts.
At the center of the room stands Dr. Celina M. Yong. For an interventional cardiologist, this is the moment where years of training converge – threading delicate instruments through arteries no wider than a strand of spaghetti to reopen blood flow to the heart. But when the room quiets and the case is over, Dr. Yong’s attention shifts beyond the cath lab walls.
She thinks about the patients who never made it there. The ones whose heart attacks went untreated. The ones who couldn’t afford medication. The ones who live hours from the nearest specialty center.
Dr. Yong is an Associate Professor of Medicine at Stanford University School of Medicine and Director of Interventional Cardiology at the VA Palo Alto Healthcare System. She belongs to a rare group of physician-leaders who move seamlessly between the procedure room and the policy table, performing some of the most complex cardiovascular procedures in medicine while also asking a harder question: why does the system delivering that care still leave so many patients behind?
For Dr. Yong, healing the heart of medicine means repairing more than arteries. It means repairing the system around them.
Roots That Reach Far
Dr. Yong’s story begins long before Stanford. She was born to parents who immigrated from Singapore – then a developing country – to Canada, and later moved to the United States as a child. Growing up from humble beginnings gave her an early, personal understanding of what it means to navigate systems not built with all patients in mind – an instinct that would quietly shape her career. Before earning her MD from Stanford in 2007, Dr. Yong was named a British Marshall Scholar. She completed an MSc in Health Policy, Planning, and Financing at the London School of Economics and an MBA at Oxford University. During those years, she found herself in conversations with global healthcare thinkers confronting a shared reality: income, geography, and circumstance still determined the quality of care people received. She also gained firsthand exposure to the influence of policy through work at the White House, the U.S. Agency for International Development, and the World Bank. Dr. Yong absorbed those insights – and turned them into fuel.
Back in the United States, she completed her internal medicine residency at UCSF, and then returned to Stanford for both her cardiology and interventional cardiology fellowships, serving as Chief Fellow along the way. By the time she performed her first solo case, she was as prepared philosophically as she was clinically.
The Moment That Changed Everything
Early in her training, Yong witnessed a case that would shape her view of medicine.
A team at the county hospital performed a technically flawless stenting procedure. They reopened a blocked artery and sent the patient home. At first glance, the case was a success. But weeks later, that same patient returned with the artery blocked again.
The reason was simple and devastating: he could not afford the medication that would have kept it open.
What Yong had studied in policy classrooms at the London School of Economics was suddenly standing in front of her wearing a hospital gown. A healthcare system that works brilliantly for some but quietly fails others is not, in her view, a high-performing system. It is an incomplete one.
From that moment on, Dr. Yong’s leadership has been built on closing that gap — one protocol, one research study, and one patient conversation at a time.
Serving Those Who Served
At the VA Palo Alto Healthcare System, Dr. Yong brings that philosophy to life. She leads a data-driven research lab while performing complex coronary interventions and transcatheter aortic valve replacements for veterans. She also leads the VA-Cardiovascular Trials Consortium, working to expand access to cutting-edge research within the VA system.
In a recent publication in the Journal of the American College of Cardiology (JACC), Yong argued that veterans should function as partners in research, not just participants. In her own lab, that philosophy is already a reality. Veterans serve as formal co-investigators, helping shape the design of studies that will ultimately guide their care. Practicing in Silicon Valley also affords another advantage. Dr. Yong collaborates with engineers and technology leaders to explore scalable tools that can deliver expert cardiovascular care to patients who may face challenges to accessing care at major medical centers.
Calm in the Storm, Open at the Table
In the cath lab, every second matters. Every procedure demands both technical precision and a team environment where every voice feels empowered to speak up the moment something seems wrong.
Dr. Yong has built a culture designed around both. She calls it flattening hierarchical barriers. When a procedure does not go as planned, the team reviews it together, with all stakeholders invited. Nobody is blamed. The system is examined. She believes this radical transparency is what transforms skilled individuals into truly reliable teams.
Protecting the People Behind the Procedures
For decades, interventional cardiologists absorbed occupational radiation exposure while wearing heavy lead protection, with little institutional attention to the cumulative risks. When Dr. Yong navigated her own pregnancy as a trainee, the issue became personal. She pushed for change, advocating for real-time radiation monitoring and modern shielding for her entire team. She also contributed to the PBS documentary Scattered Denial and collaborated with the Society for Cardiovascular Angiography and Interventions (SCAI) to develop an expert consensus statement on radiation safety. Her message is clear: the next generation of cardiologists should never have to choose between their profession and their long-term health.
The Advantage in Being Different
Early in her career, Dr. Yong was often the only woman in the room — sometimes the only woman in the entire auditorium. Rather than viewing that difference as a disadvantage, she came to see it as a source of perspective. Standing outside the traditional frame of a specialty can reveal angles others might not see.
Her research published in JACC supported that idea with data: women principal investigators enroll women patients into cardiovascular trials at significantly higher rates. The implication is profound. Representation is not simply about fairness – it is about scientific accuracy. Now an Associate Editor at JACC, she works to elevate the most rigorous science to advance cardiovascular care. She also actively mentors early-career physicians, encouraging trainees with a consistent message: the qualities that make you different can often be exactly what your field needs.
Leading Without a Map
When COVID-19 arrived in early 2020, it erased every established protocol. Dr. Yong faced decisions with no precedent: when to bring heart attack patients into the lab, how to protect her team, and how to act when the science was still evolving. She moved quickly – conducting national surveys, gathered input from cath lab leaders across the country, and publishing expert guidance at the moment the field needed it most.
That period reinforced a core lesson she now teaches trainees: Resilience is not simply about plowing forward. It requires the ability to pivot when necessary, and to trust your experience and judgment when the picture is incomplete.
From Guidelines to Legacies
Dr. Yong has co-authored some of the most widely used clinical guidance in American cardiology, including the ACC/AHA/SCAI Coronary Revascularization Guidelines. Yet she is equally clear about their limits. A guideline only succeeds when a physician translates it into the lived experience of the patient sitting in front of them – adapting evidence to circumstance, priorities, and real life.
When a patient makes it to the cath lab, the results are often immediate. A blockage opens. Blood flows again. It is the kind of moment that draws many physicians to cardiology in the first place—the clarity of a problem solved, a life restored.
But Yong knows that the story of a patient’s heart rarely begins or ends inside the procedure room. It begins in the systems that determine whether someone receives care in time, whether research reflects the patients it serves, and whether the next generation of physicians can practice medicine without sacrificing their own well-being.
Her work is a reminder that the most important advances in medicine do not always begin in laboratories. Sometimes they begin with a physician who looks at a broken system and decides – with steady resolve – that it does not have to stay that way.
