Targeting Cardiologists in the US

Cardiologists are one of the highest-value and hardest physician audiences to reach online. There are only about 34,000 practicing Cardiologists in the US to care for the nation’s leading cause of death, Cardiovascular Disease, and the workforce is shrinking and unevenly spread. 62% of US counties have no Cardiologist at all. Our HCP Targeting is audience-based, not Contextual, so we reach the Cardiologist as a clinician and as a person, wherever they browse: news, finance, technology, sport, travel, food, lifestyle and health content alike. That’s broader reach across brand-safe, premium inventory, through Programmatic and Managed Campaigns, in the US.

Our HCP Targeting (including this Cardiologist Targeting Segment) is available in the USA only, delivered with geo-targeting to the United States.

Need to reach HCP audiences based outside the US? It’s harder, but we’ve had success targeting them through Clinical Websites and Contextual Targeting.

The Cardiologist Audience

There are about 34,000 practicing Cardiologists in the US, and demand for them is climbing fast as the population ages and Cardiovascular Disease stays the country’s number one cause of death. That scarcity is the point: Cardiologists sit at the center of how heart and vascular disease is diagnosed, treated and managed, which makes them one of the highest-value audiences in medicine for Pharmaceutical, Medical Device and Healthcare Technology advertisers. Cardiology is also a deeply subspecialized field: Interventional Cardiology, Electrophysiology, Heart Failure and Transplant, Cardiac Imaging, Structural and Congenital Heart Disease, and Preventive Cardiology. Each is really its own sub-audience, with its own drugs, devices and buying decisions.

For scale, the American College of Cardiology counts more than 49,000 members across the cardiovascular care team, though not all are practicing US physicians.

Cardiologists work across more settings than most people realize. You’ll find them in Hospital Cardiac Catheterization Labs and Coronary Care Units, in Electrophysiology and Echocardiography Labs, in Outpatient Cardiology Clinics, and across private and Hospital-owned Cardiology groups. Where a Cardiologist practices shapes their formularies, buying committees and device preferences, so the setting matters as much as the specialty.

Why Advertise to Cardiologists

Cardiologists sit on top of one of the largest prescribing and device markets in all of medicine. On the drug side they choose and manage anticoagulants like apixaban and rivaroxaban, antiplatelets, lipid-lowering therapy from statins to PCSK9 inhibitors and inclisiran, Heart Failure therapies like SGLT2 inhibitors and ARNIs, plus antiarrhythmics and antihypertensives. On the device side they drive demand for Drug-eluting Stents, Pacemakers and Implantable Defibrillators, TAVR and Structural Heart Valves, Ablation Catheters, Cardiac Monitors, and Echocardiography and Imaging systems.

Their influence reaches well beyond their own patients. Cardiologists shape hospital drug formularies and sit on the committees that sign off capital equipment like Cath Lab and Imaging systems, and in private and Hospital-owned Cardiology groups they often have a direct hand in what gets bought.

Training is a market of its own. Cardiologists complete a three-year Cardiovascular Disease fellowship after an Internal Medicine residency, are board-certified through the American Board of Internal Medicine, and many add further fellowships in Interventional Cardiology, Electrophysiology, Heart Failure or advanced Imaging, all with ongoing CME requirements. Cardiology also runs one of the busiest congress calendars in medicine, with the ACC Annual Scientific Session, AHA Scientific Sessions, TCT and Heart Rhythm among them, and education and courses year-round. Together, that makes them a high-value audience for Pharmaceutical, Medical Device and Medical Education advertisers, as well as the medical conferences and congresses working to drive attendance.

Take an “Always On” Strategy for Targeting Cardiologists

Finding a small audience like Cardiologists is a needle-in-a-haystack job. There are only about 34,000 of them in the US, spread thin across a growing and aging patient population, and they’re some of the busiest people in medicine: on call for heart attacks and arrhythmias, moving between the Cath Lab, the clinic and the wards. You can rarely predict when one is online, whether it’s between cases, after a night on call or on a weekend.

That’s why we recommend an Always On strategy for an audience like this: run the campaign 24/7, 365 days a year so you reach Cardiologists whenever they surface, not just in a short burst. Continuous delivery builds reach and frequency over time, so you’re already in front of them by the time your message matters most.

An Always On budget goes further with an Omnichannel approach. Rather than betting on one screen, you reach Cardiologists across the whole day: on their phone in the staff room, through a podcast in the car, on the office desktop between patients, and on Connected TV while they unwind at home. Same audience, more moments, more chances for your message to land.

Frequently Asked Questions (FAQs)

A Cardiologist is a physician (MD or DO) who diagnoses and treats diseases of the heart and blood vessels, from Coronary Artery Disease and Heart Failure to Arrhythmias and Valve Disease. In the US they complete a three-year Cardiovascular Disease fellowship after an Internal Medicine residency and are board-certified through the American Board of Internal Medicine.

Around 34,000 practice in the United States, and the workforce is shrinking relative to demand. 62% of US counties have no Cardiologist at all. It’s a small, high-value audience, which is why audience-based targeting works far better than hoping to catch them on a handful of medical sites.

Interventional Cardiology, Electrophysiology, Heart Failure and Transplant, Cardiac Imaging, Structural and Congenital Heart Disease, and Preventive Cardiology. If your product fits one of these areas, we can target that subspecialty specifically.

A Cardiologist is a physician who diagnoses and manages heart disease medically and through catheter-based procedures. A Cardiac Surgeon operates on the heart and great vessels, and an Electrophysiologist is a Cardiologist who subspecializes in Heart Rhythm disorders and ablation. They often work as one heart team, and we can target all three if your campaign needs the wider group.

Through our HCP Targeting. We package a Cardiologist audience segment you can run as a Deal ID / PMP in your own DSP, or hand to our managed team to run for you.

Our targeting is audience-based, not contextual, so we reach Cardiologists wherever they browse: news, finance, technology, sport, travel, food, lifestyle and health content. That’s much broader than health sites alone, across brand-safe, premium inventory.

No. It’s delivered with geo-targeting to the United States only. To reach HCP audiences based elsewhere, we use clinical websites and contextual targeting instead.

HCP Targeting reaches healthcare professionals: physicians, nurses, pharmacists and other clinicians, as an audience rather than by the page they’re on. Because it’s audience-based, we reach the professional wherever they browse, not just on medical sites.

Yes. The data is privacy-safe and de-identified, so you reach professional audiences without handling any personal health information.

Beyond Cardiologists, we build HCP segments for Anesthesiologists, Pulmonologists, Obstetricians, Neurologists, Pediatricians, Geriatricians, Gastroenterologists, General Practitioners and more. See all the audiences we cover on our HCP Targeting page.
