Cardiology

What Is Cardiology? Which Diseases Does the Cardiology Department Treat?

Cardiology is a medical specialty that focuses on the diagnosis, treatment, and follow-up of diseases related to the heart and circulatory system. Cardiology specialists (cardiologists) evaluate many cardiovascular conditions such as heart attack, heart failure, arrhythmias, hypertension, and vascular occlusions.

Heart diseases are among the leading causes of death worldwide. Therefore, early diagnosis, regular cardiology check-ups, and healthy lifestyle habits are vital for maintaining heart health.

What Does Cardiology Do?

The cardiology department deals with the diagnosis and treatment of structural and functional heart diseases as well as disorders of the cardiovascular system. Cardiologists determine the underlying cause of diseases using advanced imaging techniques and interventional procedures, plan appropriate treatment, and monitor patients regularly.

Cardiology is an internal medicine–based specialty and collaborates with other medical disciplines, such as cardiovascular surgery, when necessary.

Which Diseases Does Cardiology Treat?

The main conditions treated by the cardiology department include:

• Coronary artery disease (arterial blockages)
• Heart attack (myocardial infarction)
• Heart rhythm disorders (arrhythmias)
• Heart failure
• Hypertension (high blood pressure)
• Heart valve diseases
• Cardiomyopathy (heart muscle diseases)
• Congenital heart diseases
• Pericarditis (inflammation of the heart lining)
• Aortic and major vascular diseases
• Hypercholesterolemia (high cholesterol)

What Are the Symptoms of Cardiac Diseases?

Heart and vascular diseases may present with various symptoms. The most common cardiological symptoms include:

• Chest pain or a feeling of pressure
• Shortness of breath (especially with exertion)
• Palpitations and irregular heartbeat
• Dizziness or fainting
• Swelling in the legs and ankles
• Excessive fatigue and weakness
• Cold sweating
• Pain radiating to the arm, back, or jaw

If one or more of these symptoms are present, consultation with a cardiology specialist should not be delayed.

Diagnostic Tests and Examinations in the Cardiology Department

A wide range of advanced tests and imaging methods are used to diagnose cardiovascular diseases.

Commonly Performed Cardiology Tests

• Electrocardiography (ECG): Measures the electrical activity of the heart
• Echocardiography (ECHO): Evaluates heart structure and valves using ultrasound
• Exercise (Stress) Test: Assesses the heart’s response to physical activity
• Holter Monitoring: Provides 24–48 hour rhythm monitoring
• Blood Pressure Holter: Measures blood pressure throughout the day
• Coronary Angiography: Provides detailed imaging of coronary arteries
• CT Angiography: Non-invasive evaluation of coronary vessels
• Cardiac MRI: Used to analyze heart muscle and congenital conditions
• Blood Tests: Measures values such as troponin, BNP, and cholesterol

Treatment Methods in Cardiology

Cardiology treatment is personalized based on the type and severity of the disease.

Treatments Used in Cardiology

Medical Therapy:

• Antihypertensive medications
• Blood thinners
• Cholesterol-lowering drugs
• Antiarrhythmic medications

Interventional Cardiology Procedures:

• Angioplasty
• Stent implantation

Cardiac Rhythm Devices:

• Pacemakers
• ICDs (implantable cardioverter-defibrillators)

Lifestyle Modifications:

• Healthy nutrition
• Regular exercise
• Smoking cessation
• Stress management

Regular monitoring and follow-up programs

Difference Between Cardiology and Cardiovascular Surgery

Cardiology:
Focuses on diagnosis, medical therapy, and non-surgical interventional procedures.

Cardiovascular Surgery:
Deals with conditions requiring surgical interventions such as bypass surgery and valve operations.

Both specialties work collaboratively to provide the most appropriate treatment for patients.

Recommendations for Protecting Heart Health

The following habits are essential for preventing heart diseases:

• Exercise regularly
• Avoid smoking and tobacco products
• Maintain a healthy and balanced diet
• Limit salt and processed foods
• Maintain an ideal body weight
• Regularly monitor blood pressure, cholesterol, and blood sugar
• Get adequate sleep and manage stress

Frequently Asked Questions About Cardiology

What does cardiology deal with?
It focuses on the diagnosis and treatment of heart and vascular diseases.

What complaints require a cardiology visit?
Chest pain, palpitations, shortness of breath, and fainting sensations.

What is ECHO?
A diagnostic method that uses ultrasound to visualize the heart.

How often should cardiology check-ups be done?
Individuals without risk factors should have annual check-ups; high-risk individuals should be evaluated more frequently based on their physician’s recommendation.
