Redefining the Cardiologist’s Role
Dr. Andrew Rudin, MD on Why Modern Heart Care Requires More Judgment, Not Just More Tools
According to Dr. Andrew Rudin, MD, a nationally recognized cardiologist and educator, the biggest challenge facing today’s heart doctors is not what they can do—it’s knowing when not to do it.
“We’ve built an extraordinary machine,” says Dr. Rudin, “but if we don’t operate it with judgment and restraint, we end up doing more harm than good.”
Beyond the Procedure: A Shifting Identity
Cardiology has long been defined by its capacity to intervene. Catheterizations, angioplasties, stents, and ablations are all part of the profession’s signature skillset. And rightly so—these procedures have saved countless lives, especially in acute settings like heart attacks or severe rhythm disturbances.
But over the past two decades, a growing body of research has raised an uncomfortable question: Are cardiologists doing too much for patients who don’t need it?
The answer, Dr. Rudin suggests, is yes. Not because of negligence or greed, but because the field has not yet fully adjusted to the implications of its own data. When studies like COURAGE, ORBITA, and ISCHEMIA show that many stents in stable patients offer no improvement in outcomes, it forces a reckoning—not just with how cardiologists practice, but with how they define success.
“Success is not filling the schedule with procedures,” Rudin says. “It’s knowing which ones to avoid.”
Overuse Is Not Just a System Problem—It’s a Clinical One
Much has been written about systemic drivers of overtreatment: fee-for-service reimbursement, malpractice fears, and institutional momentum. But Dr. Rudin argues that the root issue is clinical—a mindset that equates visibility with necessity, and action with virtue.
Cardiology, perhaps more than any other specialty, is vulnerable to this thinking. A minor blockage on a scan, a brief arrhythmia on a Holter monitor, or a borderline blood test can trigger a cascade of testing and treatment. Patients may undergo stenting, ablation, or lifelong medications for conditions that posed little or no actual risk.
“We’ve medicalized the normal,” Rudin explains. “And when you start treating numbers instead of people, you lose sight of what care really means.”
The Patient's Experience: Overwhelmed, Not Reassured
For patients, more tests often feel like more care. But in reality, they can introduce confusion, anxiety, and even harm. Dr. Rudin recounts the story of a healthy 52-year-old man referred to him after a calcium score screening showed “moderate coronary calcification.”
The patient was terrified. He’d already undergone a stress test, a cardiac MRI, and a full lipid panel before arriving in Rudin’s office. None of the findings indicated significant disease. But the psychological damage had been done. The patient had stopped exercising, avoided travel, and had begun experiencing daily chest tightness—none of which existed before the screening.
“We turned a healthy person into a cardiac patient,” Rudin says. “And all in the name of prevention.”
This is not an isolated case. Patients are routinely subjected to cascades of care for findings that require monitoring—not management. The net result: a population made sicker by the very system meant to protect them.
Teaching the Next Generation to Slow Down
Part of Dr. Rudin’s mission is educational. As a mentor to cardiology fellows and residents, he encourages them to challenge the assumption that doing more is doing better. He pushes them to ask three questions before every test or intervention:
-
Will this result change my management?
-
Does the patient understand what we're looking for?
-
Are we solving a problem—or just chasing a number?
He also advocates for teaching communication as a core clinical skill. In his view, the ability to explain why something is not being done is just as important as knowing how to do it.
“Restraint isn’t passive,” he says. “It’s active. It’s grounded in courage, empathy, and science.”
The Ethic of Restraint
At the heart of Dr. Rudin’s message is an appeal to professional ethics. He believes that modern cardiologists must reclaim their role as stewards—not just of technology, but of time, attention, and trust.
This means being transparent about uncertainty. It means telling patients that sometimes the best medicine is no medicine. It means choosing clarity over control, and evidence over instinct.
It also means confronting the discomfort of inaction. In a culture that celebrates the dramatic, choosing not to intervene can feel like a failure. But Rudin insists that this is where real leadership lies.
“You don’t need a scalpel to save a life,” he says. “Sometimes, you need a conversation.”
A Call to Redefine Excellence
Dr. Rudin believes the time has come to redefine what excellence in cardiology looks like. It’s not just technical skill or procedural volume. It’s clinical discernment. It’s the ability to sit with complexity. And above all, it’s the humility to admit that doing less can often mean doing more.
He envisions a future where cardiologists are recognized not only for what they perform, but for what they prevent. Where the badge of honor isn’t how many patients they stented—but how many they protected from unnecessary harm.
And where wisdom, not just speed, becomes the hallmark of modern care.
Final Thoughts
As technology continues to evolve, the cardiologist’s toolbox will only grow. But tools alone do not make a healer. As Dr. Andrew Rudin, MD reminds us, the real work of medicine happens not in the cath lab or on the monitor screen—but in the space between knowledge and judgment.
In that space, every cardiologist has a choice. To intervene—or to pause. To fix—or to guide. To act—or to listen.
The future of cardiology depends on choosing well.
