Cardiology is the medical specialty focused on diseases and disorders of the heart and cardiovascular system. With cardiovascular disease remaining the leading cause of death in the United States and procedural innovation continuing to expand the field, cardiology is one of the most actively recruited physician specialties — across non-invasive, interventional, electrophysiology, advanced heart failure, and pediatric cardiology subspecialty tracks.
Cardiology is a medical subspecialty of internal medicine focused on the prevention, diagnosis, and treatment of diseases and disorders of the heart and cardiovascular system. Cardiologists complete three years of internal medicine residency followed by three or more years of cardiovascular disease fellowship training, with additional one-to-two-year fellowship training required for interventional cardiology, electrophysiology, advanced heart failure and transplant, structural heart disease, and adult congenital heart disease subspecialties.
Modern cardiology spans a continuum from outpatient prevention and chronic disease management (lipid management, heart failure clinics, atrial fibrillation programs) through diagnostic procedures (echocardiography, stress testing, cardiac CT, cardiac MRI, nuclear cardiology), interventional procedures (cardiac catheterization, percutaneous coronary intervention, structural heart procedures including TAVR and MitraClip), and electrophysiology procedures (ablation, device implantation including pacemakers, ICDs, and CRT devices).
Cardiology is among the largest medical subspecialties by physician count, but also among the most rapidly evolving. The growth of structural heart disease procedures, complex coronary intervention, AI-assisted echocardiography interpretation, and remote cardiac monitoring has reshaped what modern cardiology programs need from new hires.
Cardiology has fragmented into multiple subspecialty tracks. Each requires distinct fellowship training and addresses a different segment of cardiovascular care:
Non-Invasive Cardiology — Outpatient general cardiology with diagnostic imaging (echo, stress, cardiac CT, cardiac MRI, nuclear cardiology). The largest segment of cardiology practice.
Interventional Cardiology — One-to-two-year fellowship trained interventional cardiologists performing diagnostic and therapeutic cardiac catheterization, PCI, and (with additional training) structural heart procedures.
Electrophysiology (EP) — Two-year fellowship trained EP cardiologists performing ablation, device implantation (pacemakers, ICDs, CRT), and complex arrhythmia management.
Advanced Heart Failure / Transplant — One-year fellowship trained heart failure cardiologists managing cardiomyopathy, mechanical circulatory support (LVAD), and cardiac transplant.
Structural Heart — Subspecialty interventional cardiologists performing TAVR, MitraClip, paravalvular leak closure, and other structural procedures. Growing rapidly with expanded TAVR indications.
Adult Congenital Heart Disease (ACHD) — Fellowship-trained ACHD cardiologists managing adults with congenital heart disease. Concentrated at academic and tertiary referral centers.
Pediatric Cardiology — Subspecialty pediatric cardiology fellowship-trained physicians at children's hospitals.
Cardiology demand continues to grow steadily, driven by the aging US population (peak cardiovascular disease incidence is age 65–84), rising prevalence of obesity and diabetes that accelerate cardiovascular disease, and continued procedural expansion in structural heart and complex coronary intervention. The American College of Cardiology projects sustained cardiology workforce demand growth through 2035, with particularly acute gaps in rural and small-metro markets.
Subspecialty supply varies meaningfully by track. Interventional cardiology and EP have grown rapidly with strong fellowship output, while advanced heart failure, ACHD, and pediatric cardiology face persistent shortage. Non-invasive cardiology supply is generally adequate in metropolitan markets but constrained in rural areas where many counties have no resident cardiologist.
Cardiology compensation has risen meaningfully since 2020. Non-invasive cardiologists typically earn $400,000–$575,000, interventional cardiologists $500,000–$750,000+, and EP cardiologists $550,000–$800,000+. Rural and small-metro markets often pay 15–25% above national averages with sign-on bonuses of $100,000–$300,000.

After three years of internal medicine residency, general cardiology fellowship is three years. Additional subspecialty fellowships add one year for interventional cardiology, two years for electrophysiology, one year for advanced heart failure, one year for structural heart, and one-to-two years for adult congenital heart disease. Total post-medical-school training for a structural heart cardiologist is typically 9–10 years.
Cardiology workforce demand is projected to outpace supply through at least 2035, with particularly acute gaps in rural and small-metro markets. Subspecialty supply varies — non-invasive and interventional cardiology have stronger pipelines, while advanced heart failure, ACHD, and pediatric cardiology face persistent shortage.
Non-invasive cardiologists typically earn $400,000–$575,000, interventional cardiologists $500,000–$750,000+, electrophysiologists $550,000–$800,000+, and advanced heart failure specialists $400,000–$600,000. Subspecialty fellowship and procedural mix are the dominant compensation drivers.
