Types of Cardiologists Based On Their Role & Expertise

Cardiology is a special branch of internal medicine. A physician who practices cardiology is known as cardiologist. Initially, practice of cardiology goes through internal medicine residency program. After completing that program, an individual needs to attend fellowship program to obtain more specialized training in which he/she decides the type of cardiology wants to practice.

The roles of cardiologists are to provide healthcare to diagnose, prevent & treat diseases of the heart & cardiovascular system including arteries. There are various fields of cardiology. But one needs to understand that a cardiologist is not a surgeon. The person who performs an open heart surgery is known as cardio-thoracic surgeons; not a cardiologist.

Types of Cardiologists

There are many various types of cardiologists. Primarily, there are four types of cardiologists considering their qualification and field of study. These are:

  1. Non-Invasive Cardiologist
  2. Invasive, Non-Interventional Cardiologist
  3. Interventional Cardiologist
  4. Electrophysiologists (EP)
  5. Non-Invasive Cardiologist

A non-invasive cardiologist is more into office-based practice. Their role is to see patients to prevent & manage heart related problems. An average non-invasive cardiologist visits around 25–30 patients in a day. This type of cardiologists do not follow any procedures, they mainly perform diagnostic tests to find heart related problems. Depending on the test results, non-invasive cardiologists prescribe drug therapy or dietary program or even go for a surgical procedure. Non-invasive cardiologist can also refer patient to another physician.

  1. Invasive, Non-Interventional Cardiologists

The work of an invasive cardiologist includes all the work of a non-invasive cardiologist and bit more. Invasive cardiologist primarily works in cardiac labs. They are trained in performing diagnostic procedure known as cardiac catheterization that causes blockages in the arteries. This type of cardiologists spend their time in office & “catheterization lab”. However, if blockage is found, the responsibility of an invasive cardiologist is not to fix the problem and refer the patient to an interventional cardiologist.

  1. Interventional Cardiologists

This type of cardiologist can perform more advanced treatments and procedures compare to invasive & non-invasive cardiologist. Interventional cardiologists spend most of their time in hospitals performing procedures from open blocked arteries to balloon angioplasty or even placing little mesh stents into arteries.

  1. Electrophysiologists (EP)

Electrophysiology is another branch of cardiology. It is the study of bio-electrical impulses of heart which control the pace of one’s heartbeat. The moment electrical impulses stop functioning properly, fatal & untreated disease similar to heart arrhythmia. Not very long ago, inserting a pacemaker was the only option to correct irregularities of the heart. The introduction of electrophysiology has reduced the use of pacemaker. EPs perform a variety of other surgical procedures including ablation that causes malfunctioning of heart, drug therapy to manage arrhythmias.

There are many cardiologists are available across the USA who have qualifications & expertise in solving & treating different types of heart & cardiovascular problems. Based on the expertise and experiences, cardiologists settle their fees. The need for cardiologists arises when a general physician thinks that the cause of the chest pain is due to heart related problems or issues.
