Cardiologist Definition, 14 Tasks, Actions Perfomed, and How They Maintain The Heart

Cardiologist Definition, Tasks, Actions Perfomed, How They Maintain The Heart – The heart is one vital part of the body. So, it needs an expert to help it heal when developing problems. You can become a cardiologist if you like to help people heal, especially if you like heart problems.

Cardiology is a branch of medical science that specialized in studying disorders in the heart and blood vessels. What are the diseases and when do you need to see a cardiologist?

In practice, cardiology is a science of diagnosing and treating various cardiovascular diseases such as coronary heart disease, heart rhythm disorders (arrhythmias), heart failure, heart valve disease, and congenital heart defects.

Cardiologist Definition

Physicians who specialize in cardiology are referred to as cardiologists, doctors who specialize in heart and blood vessels, or doctors who specialize in cardiology.

Types of Cardiology

Although stroke medicine is one of the sub-specialties of cardiology, some cardiologists choose it as their choice. Instead, most cardiologists prefer to develop their roles in areas of special interest, such as:

  • Older persons congenital heart disease
  • Cardiac imaging
  • Electrical device therapy
  • Electrophysiology
  • Heart failure (which includes heart transplantation and support devices)
  • Interventional cardiology.

Cardiologists Tasks

After knowing cardiologist definition and cardiology types, then we will discuss about Cardiologists tasks.

Cardiologists are tasked with treating patients with conditions such as:

  • Angina, chest pain caused by narrowing of the blood vessels of the heart or coronary heart disease.
  • Arrhythmia, irregular heartbeat, too slow, or too fast.
  • Heart murmurs (rustling sounds made by turbulent blood near or inside the heart). The heart murmur can be heard by the doctor using a stethoscope.
  • Heart attack.
  • Cardiac arrest.
  • Heart valve disease.
  • Cardiomyopathy, or abnormalities in the heart muscle.
  • Diseases of the blood vessels, such as atherosclerosis, arteritis, varicose veins, and aortic abnormalities.
  • A heart tumor.
  • Coronary artery thrombosis or blockage of the heart’s blood vessels due to blood clots
  • High blood pressure (hypertension) and high cholesterol.
  • The presence of a hole in the heart and other forms of congenital heart disease.
  • Heart failure.

Actions performed by Cardiologists

After knowing cardiologist definition, tasks and cardiology types, then we will discuss about Actions performed by Cardiologists.

In making a diagnosis, a cardiologist will trace the patient’s medical history and perceived symptoms. After that, the doctor will perform a physical examination of the heart to evaluate if there is a heart defect. After that, to ensure a diagnosis, often the doctor will suggest additional examinations or further tests, such as:

  • ECG (electrocardiography).
  • X-rays, CT scans, MRIs, angiography.
  • Echocardiogram (cardiac ultrasound).
  • Stress test.
  • Blood test.

Once the diagnosis is confirmed, the cardiologist will determine the treatment steps to treat the disease suffered by the patient. Treatment with certain medications and medical procedures may also be required, according to the diagnostic results.

The purpose of treatment is to stabilize the condition, control symptoms in the long term, and cure the disease if possible. In addition to medical treatment, patients will also be advised to reduce stress, undergo a healthy diet, and exercise diligently to improve their condition.

Some special medical measures in the treatment of heart and vascular disease, which is the competence of cardiologists include:

  • Cardiac catheterization.
  • Angioplasty.
  • Angiography.
  • Pacemaker implants or Implantable Cardioverter Defibrillator that is implanted under the skin of the chest or abdomen.

The competence of cardiologists is not only related to heart disease and heart vessels, but also includes common vascular diseases, such as varicose veins, vascular thrombosis, and peripheral artery disease.

Cardiologist does to maintain their heart

Sleep eight hours each night

Getting a high quality sleep benefits for the health of the body. With enough sleep, we will feel ready to undergo various activities.


Negative thoughts and feelings of sadness can have a bad effect on our bodies. Those thoughts and feelings will expel catecholamine which can lead to heart failure. According to Archana Saxena, MD, a cardiologist at the NYU Lutheran Medical Center, to avoid stress is actually easy. We can do meditation for 20 minutes to find comfort.

Using the stairs

No wonder that the number of heart attacks increased after the introduction of the elevator. In fact, a little exercise every day is essential for heart health. Richard Wright, a cardiologist, advises, use the stairs if we want to go upstairs. This will make us physically active, and certainly good for the heart.


We all know that high stress levels are bad for the heart. It’s actually not just stress, high levels of anxiety are also bad for heart health. Well, through yoga, we can make the body and mind more relaxed. We can also find a life balance through this exercise.

Sufficient water consumption

Drinking five or more glasses of water can lower the risk of death from heart disease. Lack of water can lead to dehydration that increases hematocrit (blood cell volume, especially red blood cells). This is what can harm our heart health.
