  • adult congenital heart disease
  • cardiac imaging
  • electrical device therapy
  • electrophysiology
  • heart failure (which includes heart transplantation and support devices)
    interventional cardiology.

Meanwhile, if you’re more interested in the science behind cardiology, you can pursue academic opportunities in the field of research.

What Qualifications Do I Need to Become a Cardiologist?

Becoming a cardiologist is a very easy process and this is not true. Contrarily, it involves a deep level of focus, commitment, and hard work to actually excel.

Meanwhile, before you begin your quest to study cardiology, you must fulfill certain requirements. And these requirements vary per school but have some constants.

Hence, the qualifications include;

  • CGPA of nothing less than 3.5
  • Excellent performance in subject areas such as Chemistry, Biology, and Maths
  • Possess supporting documents including a bachelor’s degree in Medicine

In addition to these qualifications, you have to fulfill other requirements stated by the school. However, fulfilling the requirements is the first stage in achieving your dream.

How Much Do Cardiologists Earn?

Cardiologists earn well. Hence, the specificity and carefulness of their duty should only yield them a befitting financial reward.

On average, cardiologists earn as much as $512,000 per year. Moreso, this salary is in the absence of benefits and bonuses.

Medical issues keep getting complicated, so research remains ongoing in this career path.

Job Outlook

The job outlook for all cardiologists is better than average, with an expected growth of 13% between 2016 and 2026.

The two catalysts of job growth are population increases and the aging population in the United States.

Furthermore, technological advancements that expand diagnostic options also make it easier for more people to get both non-invasive and invasive cardiology treatments and services.

Do all Cardiologists Perform Surgery?

A cardiologist will primarily diagnose disorders of the heart and treat them with medication. 

Cardiologists also perform interventions on the arteries in the heart, working through puncture wounds in the groin, but they do not perform open surgery.

How to Become a Cardiologist

Now that you have decided to study cardiology, you need to learn the step-by-step requirements you need to follow.

Essentially, these steps will act as guides in helping you know how you can start and scale your career as a cardiologist.

Hence, they include;

Step 1: Gain a Bachelor’s Degree

Individuals interested in cardiology must undertake a bachelor’s degree in a science or health-related field. Basically, you’ll need to complete such a bachelor program in four years although some might be more.

After completing premedical courses like chemistry, physics, and biology, you need to study well.

Truly, the higher your GPA, the more likely you are to get into medical school as this is where you start building your foundation.

Step 2: Enrol in a Medical School

Four years of consistent hard work and study at the University will earn you a shot at cardiology. However, once you’ve graduated from university, it’s time for four more years of education, this time at medical school.

After a good number of classes exams and lectures, you will be transferred to a hospital where you can apply the skills you’ve built so far.

At the end of this process, you will eventually earn your degree (Medical Doctor (M.D.) degree or Doctor of Osteopathic Medicine (D.O.) degree).

Conclusively, you can choose the best institute to study at after you have assessed them and most importantly, fulfilled their admission requirements.

Step 3: Get a Medical License

You don’t graduate from medical school and go open your hospital nor do you run an apprenticeship program and feel it qualifies you to practice cardiology. No! It doesn’t work like that.

Regulatory bodies ensure that unqualified individuals don’t open up these centers and endanger the lives of humans.

So after medical school, your next step is to earn a medical license. To practice medicine, you must obtain this license by taking the licensing exam.

To a large extent, the exam will demonstrate your knowledge and skills and determine whether you are ready for a future career in cardiology.

Therefore, your performance in the licensing exams will determine your next big step.

Step 4: Finish your Residency Program

At this stage, this career path gets sweeter. Hence, you should expect it to get a little tougher.

After obtaining your license, you’ll need a place where you can practice under the strict supervision of your senior colleagues. Therefore, this apprenticeship program is called residency.

So a postgraduate, your next three years will be complete training with a residency in internal medicine.

Before specializing, you must complete several clinical rotations in different internal medicine specialties such as oncology, respiratory medicine, and more.

Meanwhile, within these three years, you will create your portfolio and obtain letters of recommendation from different experts in the field, which can eventually put you up for a cardiology fellowship.

Step 5: Complete your Cardiology Fellowship

The residency program must have taught you a lot about cardiology, and you might think that caps it all. Sorry to say, it remains just a final step that will eventually make it easy for you.

Hence, you must finish a cardiology fellowship, which usually takes two to three years to complete. In the fellowship, you learn to manage a great range of cardiac conditions, perform procedures, and conducting clinical research. Thus, this will eventually earn you a certification.
