Cardiology is a field that studies and treats heart and blood vessel diseases. A person with a heart or cardiovascular disease may be referred to a cardiologist. Several medical conditions can be diagnosed and treated in this field, including heart defects, heart failure, valvular heart disease, and electrophysiology. Internal medicine physicians who specialize in cardiology are known as cardiologists.
What Does Cardiology Involve?
Cardiologists undergo a comprehensive examination and review of the patient's medical history and physical examination before making a diagnosis. In addition to checking the patient's weight, heart and lung capacity, they may also conduct diagnostic tests on pulmonary blood pressure.
Who is a Cardiologist?
A cardiologist is a medical professional who specializes in diagnosing and treating diseases affecting the cardiovascular system, which includes the heart and blood vessels. Cardiologists also educate their patients on how to maintain healthy heart habits.
Cardiologists are trained to diagnose and treat heart attacks, heart failure, disease of the heart valves, irregular heartbeats, and hypertension. A cardiologist can order electrocardiograms, echocardiograms, and CT scans (computed tomography) to determine the cause of the problem. According to the diagnosis, they may suggest medication, exercise programs, or cardiac catheterizations.
What Does a Cardiologist Do?
A cardiologist is a medical professional who, through screenings and checkups, can help prevent heart disease. They are trained to treat the following symptoms of heart conditions or heart diseases-
- Heart attacks;
- Heart disease (or coronary artery disease) occurs when blood vessels that bring nutrients to your heart are blocked;
- Deficiency in the heart's ability to pump blood leads to heart failure;
- Heart rhythms (or arrhythmia), when your heart beats too fast, too slow, or irregularly; and
- Valve problems occur when the heart fails to open or close properly.
What Diseases Do Cardiologists Treat?
Cardiologists specialize in diagnosing, treating, and preventing various cardiovascular diseases. Some of the most common conditions that cardiologists treat are as follows:
- Atrial Fibrillation
- Ventricular Fibrillation
- Congenital heart disease
- Coronary heart disease
- Congestive heart disease
- Hypertension or high blood pressure
- High cholesterol
- Pericarditis
- Stroke
What Kind of Tests Does a Cardiologist Do?
A cardiologist can order the following tests to help with the diagnosis. Still, some of these tests could be performed by other healthcare providers:
- Cardiac catheterization
- X-ray of the chest
- MRI of the heart (magnetic resonance imaging)
- Cardiac CT scan (computed tomography)
- Coronary angiography (CA)
- Stress examinations
- Electrocardiogram (ECG) (EKG)
- Echocardiogram
- Transesophageal echocardiogram (TEE) (TEE)
- Event monitoring
- Holter monitor
- Implanted loop recorder/implantable event recorder
When Would I Need a Cardiologist?
A cardiologist may be needed if you're experiencing symptoms like dizziness, palpitations, or shortness of breath. It's possible that your cardiologist will keep working with you for a long time as they keep an eye on your health.
