Cardiac nurses work in a wide range of settings, from high-intensity hospital units to outpatient clinics and rehabilitation centers. Most are employed in hospitals, but the specialty has expanded well beyond the bedside as cardiovascular care has grown into one of the largest areas of healthcare in the country. Here’s a breakdown of where these roles actually exist and what each setting looks like day to day.
Hospital Intensive Care Units
The cardiovascular intensive care unit (CVICU) is the highest-acuity setting for cardiac nurses. These units handle patients recovering from open-heart surgery, heart transplants, and mechanical heart support devices. Nurses here manage patients in cardiogenic shock, monitor temporary artificial heart pumps, and care for some of the most medically complex cases in the hospital. At major medical centers like the University of Rochester, the CVICU has been recognized with national awards for critical care excellence, reflecting the level of skill these units demand.
One step down from the ICU, cardiac step-down units (sometimes called progressive care units) care for patients who are still acutely ill but stable enough to leave intensive care. These units typically handle heart attacks, patients recovering from angioplasty, and those with dangerous heart rhythm problems that may require temporary pacing. A large medical center might run a 23- to 24-bed step-down unit staffed entirely by cardiac-trained nurses.
Heart Failure and Transplant Units
Some hospitals operate dedicated progressive care units just for heart failure patients. These units follow patients across the full arc of their disease, from early management through the wait for a heart transplant. Nurses on these floors care for patients living with implanted heart pumps, either as a bridge to transplant or as a long-term therapy. The work involves managing invasive cardiac monitoring equipment and building sustained relationships with patients who may be on the unit for weeks or months.
Pediatric Cardiac Units
Children’s hospitals and large tertiary care centers run their own cardiac critical care units (CCCUs) separate from the adult side. A 300-bed children’s hospital might employ hundreds of registered nurses across its pediatric ICU, cardiac critical care unit, and neonatal ICU combined. Pediatric cardiac nurses care for infants and children born with heart defects or recovering from corrective surgeries, a population with very different physiology from adult cardiac patients.
Cardiac Catheterization Labs
The cath lab is one of the most distinctive environments in cardiac nursing. It’s a procedural space, not a traditional patient room. The temperature runs colder than a standard operating room, patients are typically awake during procedures, and the room is packed with specialized imaging and treatment equipment. Nurses in the cath lab monitor live fluoroscopic images and hemodynamic tracings on multiple screens while tracking how much contrast dye a patient receives, since too much can damage the kidneys or trigger allergic reactions.
Cath lab nurses also work in a radiation-prone environment. They’re often close to the fluoroscopy machine while starting IVs, managing oxygen, or assisting with airway management. Their role spans from preoperative patient evaluation through the procedure itself and continues until discharge. It’s fast-paced, technically demanding work that sits somewhere between nursing and surgical assisting.
Electrophysiology and Device Clinics
Electrophysiology (EP) labs are a close cousin of the cath lab, focused specifically on diagnosing and treating heart rhythm disorders. Nurses in EP labs assist with procedures like cardiac ablations and the implantation of pacemakers and defibrillators. Many cardiology practices also run outpatient device clinics where nurses check and adjust implanted pacemakers and defibrillators during follow-up visits. These clinics have grown significantly as the number of patients living with cardiac devices has increased.
Outpatient Cardiology Practices
A large portion of cardiac nursing happens outside the hospital entirely. Private cardiology practices and outpatient clinics employ nurses to assess patients, assist with diagnostic testing, and coordinate care across a team of specialists. Stress testing is a common responsibility. One nurse practitioner at the American Association of Nurse Practitioners described being hired initially just to run stress tests, then gradually expanding into device management and heart failure care as the practice grew.
Outpatient settings tend to offer more predictable schedules than hospital units. Nurses in these roles spend significant time on patient education, medication management, and communicating results between cardiologists, primary care doctors, and patients. As cardiology practices have expanded, many have embraced nurse practitioners for diagnostic testing and ongoing patient management.
Cardiac Rehabilitation Centers
Cardiac rehab is a growing field where nurses serve as the primary point of contact for patients recovering from heart events or surgeries. These programs operate in both outpatient specialty clinics and primary care settings. The CR nurse’s role is broad: conducting initial health assessments, counseling patients on diet, physical activity, tobacco use, and psychosocial health, and monitoring cardiovascular risk factors over time.
Research published in the Journal of Cardiovascular Nursing found that outcomes improve when rehab nurses have the autonomy to adjust blood pressure, blood sugar, and cholesterol medications within established treatment protocols. More than 95% of cardiac rehab centers reported that nurses assessed and counseled patients on dietary habits, exercise, mental health, and tobacco use at the initial visit. The work is built around sustained, one-on-one relationships. Patients who see the same nurse throughout their rehab tend to hit their health targets more consistently, making continuity a core feature of the role.
Specialized and Long-Term Care Facilities
Beyond hospitals and clinics, cardiac nurses work in dedicated cardiac care centers, long-term cardiac care facilities, and cardiac therapy centers. These settings serve patients with chronic heart conditions who need ongoing monitoring and management but don’t require hospital-level care. The day-to-day work overlaps with general nursing skills (health assessments, medication coordination, patient education) but is focused entirely on a cardiac population.
The number of these facilities has been rising. Cardiovascular disease remains one of the leading causes of death in the United States, which has driven the expansion of clinics, rehab centers, specialist offices, and research centers across the country.
Certification and Career Mobility
Where you can work in cardiac nursing depends partly on your credentials. The American Nurses Association offers the Cardiac-Vascular Nurse Board Certified (CV-BC) credential, which requires an active RN license, two years of full-time nursing experience, at least 2,000 hours of clinical practice in cardiac-vascular nursing within the past three years, and 30 hours of continuing education in the specialty. The certification is valid for five years.
Higher-acuity settings like the CVICU typically expect or require critical care certification (CCRN) on top of cardiac-specific credentials. Outpatient and rehab settings may be more accessible entry points for nurses transitioning into the specialty. The overall job market is favorable: the Bureau of Labor Statistics projects registered nursing employment to grow 5% from 2024 to 2034, with roughly 166,100 openings per year. Demand for advanced practice nurses, including nurse practitioners working in cardiology, is projected to grow about 35% in the same period.
