How to become a cardiologist

1. 1Earn a bachelor's degree with premed courses

   Time: 4 yearsCost: VariesSources 1

   Any major works, but you need the courses medical schools require, usually biology, general and organic chemistry, physics, biochemistry and math or statistics. Grades matter a great deal. Clinical volunteering, shadowing physicians and research experience strengthen an application. Spending time with a cardiology team, for example in a cardiac unit or clinic, tells you early whether the specialty suits you.

2. 2Take the MCAT and apply to medical school

   Time: 1 year (often during junior or senior year)Cost: $360 MCAT registrationSources 5, 1

   The MCAT tests biology, chemistry, physics, psychology and critical reading, and nearly all U.S. medical schools require it. Admission is competitive: schools weigh grades, MCAT scores, letters of recommendation, experience and interviews. Many applicants take one or more gap years to work, do research or reapply. You can choose MD or DO programs; both lead to full licensure and to cardiology training.

3. 3Complete medical school and the first licensing exams

   Time: 4 yearsCost: $297,745-$408,150 median cost of attendanceSources 4, 6, 7

   The first two years cover the basic and clinical sciences; the last two are clinical rotations in internal medicine, surgery, pediatrics and other fields. MD students take USMLE Step 1 and Step 2 CK, and DO students take COMLEX-USA Level 1 and Level 2-CE. A cardiology elective and strong internal medicine evaluations help when you apply for residency.

4. 4Finish an internal medicine residency

   Time: 3 years (36 months)Cost: Paid positionSources 2, 7, 9

   Cardiology is a subspecialty of internal medicine, so you first complete 36 months of ACGME-accredited internal medicine residency. You care for adult inpatients and outpatients across every organ system, take the final licensing exam (USMLE Step 3 or COMLEX Level 3), and get your state medical license. Fellowship applications go out partway through residency, so research and strong letters matter early.

5. 5Complete a cardiovascular disease fellowship

   Time: 3 years (36 months)Cost: Paid positionSources 2, 9

   ABIM requires 36 months of accredited cardiovascular disease training, with at least 24 months clinical. Fellows rotate through the cardiac care unit, consult service, echocardiography, nuclear cardiology and the cath lab, and must show competence in procedures such as right- and left-heart catheterization. Pass the ABIM internal medicine exam along the way, which is required before you can sit for the cardiology boards.

6. 6Get board certified and choose any further subspecialty

   Time: 1-2 more years for subspecialtiesCost: ABIM exam feesSources 2, 3, 9

   Passing the ABIM Cardiovascular Disease Certification Examination, while holding a valid, unrestricted license, makes you a board-certified cardiologist. Those who want to place stents need 12 more months of interventional cardiology fellowship; electrophysiology requires 24 months. Other options include advanced heart failure and transplant cardiology, adult congenital heart disease and advanced imaging. Board certification is then kept up through ABIM's maintenance program.

Programs, tuition and graduates’ earnings

U.S. Department of Education, College Scorecard (most recent cohorts, released 2026-10-15). Scorecard groups programs by 4-digit field, so a row can include related programs. Tuition is the median published undergraduate tuition and fees of the colleges offering the program (shown only for undergraduate credentials); debt is the median of programs’ median federal loan debt at completion; earnings are the national median for the field and credential four years after completion.

Requirements differ by state. Check your state’s rules in the CareerOneStop License Finder (U.S. Department of Labor) before you enroll.

Reading tests quickly and accurately

A cardiologist reads dozens of EKGs, echo images and monitor strips a day, and a missed pattern can mean a missed heart attack.

Calm under pressure

A patient with a closing artery or a dangerous rhythm needs decisions within minutes, often at night.

Fine motor control

Interventional and electrophysiology work means steering wires and catheters through vessels a few millimeters wide while watching a screen.

Explaining risk plainly

Patients deciding on a stent, ablation or device need the tradeoffs explained without jargon.

Stamina

About 14 years of training followed by call schedules and long procedure days demand steady energy.

Pay above the all-jobs median vs. cost

Low: AAMC median 4-year cost of attendance at a public medical school (class of 2026), $297,745, plus MCAT $360 (2027 testing year), USMLE Step 1 $695 and Step 2 CK $695 = $299,495. High: private-school median $408,150 plus the same exam fees = $409,900. Cost of attendance includes living expenses. Not included: college, application and interview costs, USMLE Step 3, ABIM exam fees and state license fees, which we did not verify. Residents and fellows are paid during training. Median federal loan debt for medical graduates in our data is $208,644.

Rough guide only: ignores taxes, aid, interest and earnings given up during training. How we calculate it.

• Interventional cardiologist

  Complete 12 additional months of accredited interventional cardiology fellowship after general cardiology and pass the ABIM interventional exam.

• Cardiac electrophysiologist

  Complete 24 months of clinical cardiac electrophysiology fellowship and pass the ABIM CCEP exam to ablate arrhythmias and implant devices.

• Radiologist$420,860 median

  A separate path entirely: it requires a diagnostic radiology residency, though cardiologists with advanced imaging training often work alongside radiologists on cardiac CT and MRI.

• Department chief or medical director

  Senior cardiologists move into leading a cardiology division, cath lab or heart program, sometimes after earning an MBA or other management training.
