Cardiology By the Numbers: Workforce & Job Growth Projections

There are more than 34,000 cardiologists in the United States, with the majority specializing in general cardiology.

Job growth for cardiologists is anticipated to rise 4% from 2024 to 2034, slightly above the 3% average for other specialties, according to the U.S. Bureau of Labor Statistics.

Cardiology Across the Country: Geographic Variation in Workforce Supply

National workforce totals provide only a partial picture of access to cardiology. A closer look at geographic distribution reveals differences in provider availability across states and communities.  

With cardiovascular care varying significantly across the U.S., geographic disparities leave millions without timely access to a cardiologist.

These disparities are especially severe in rural and nonmetropolitan communities, where limited local access can delay diagnosis, lengthen travel burdens, and increase reliance on nearby urban facilities.

Key Drivers: Factors Contributing to the Cardiologist Shortage

An Aging Population & Workforce: Growing Care Needs & Retirements

By 2030, projections estimate that 1 in 5 Americans will be aged 65 or older, a demographic shift with significant implications for cardiovascular care. As patients age, cardiovascular disease becomes more prevalent and more complex to manage, increasing demand for cardiology services.

At the same time that an aging population is driving demand for cardiovascular care, the cardiology workforce itself is also aging.

As more patients require care and more cardiologists approach retirement age, the gap between patient need and physician supply may become even more difficult to close. 

Increasing Demand: Rising Prevalence of Cardiovascular Conditions

Nearly half of U.S. adults are already living with some form of cardiovascular disease, and rising rates of hypertension, obesity, and diabetes are placing increasing strain on hospitals and health systems.

The demand for cardiovascular care is projected to grow steadily in the years ahead, driving higher patient volumes and greater case complexity, while placing added pressure on health systems to ensure timely access to care.

Operational & Financial Impacts: Recruitment Delays & Revenue Risk

As recruitment timelines lengthen and demand grows, hospitals and health systems may face difficulties sustaining cardiology coverage, throughput, and continuity of care.

When a cardiology position remains unfilled, the impact extends beyond recruitment, as cardiologists can generate up to seven times their annual salary for hospitals, contributing considerable revenue to their organization.

Actionable Strategies: Approaches for Ensuring Access to Cardiology Care

Implement Advanced Practice Providers: Strengthening Cardiology Access

Advanced practice providers (APPs) are playing an increasingly important role in cardiology care delivery. As cardiologist shortages persist and patient demand continues to grow, many healthcare facilities are expanding APP utilization to support access and extend cardiology capacity. 

By integrating APPs across the cardiology care continuum, healthcare facilities can create greater flexibility in care delivery while preserving cardiologists' time for more complex and specialized cases. 

Utilize Locum Tenens Cardiologists: Bridging Gaps in Coverage

Locum tenens cardiologists can help bridge immediate coverage gaps and serve as a strategic workforce resource in cardiology. Beyond filling vacancies, leaders can leverage locum tenens cardiologists to stabilize operations, support evolving care models, and maintain access to care while longer-term staffing strategies are implemented.
