Cardiology

Which Heart Conditions Are Treated in Cardiology?

Cardiology includes a wide range of cardiovascular diseases.

Common conditions include coronary artery disease, hypertension, heart failure, arrhythmias, heart valve disease, cardiomyopathy, and congenital heart problems.

Cardiologists may also evaluate chest pain, palpitations, shortness of breath, fainting, reduced exercise tolerance, and abnormal blood pressure.

The same symptom can have several possible causes, so diagnosis usually requires a combination of clinical assessment and cardiovascular testing.

How Are Heart Diseases Diagnosed?

Cardiac diagnosis begins with medical history, physical examination, and assessment of cardiovascular risk factors.

Blood pressure, heart rate, cholesterol, blood glucose, smoking history, and family history can provide important information.

Further testing may include electrocardiography, echocardiography, exercise testing, Holter monitoring, CT coronary angiography, invasive coronary angiography, or cardiac MRI.

The appropriate test depends on the suspected condition rather than using the same investigation for every patient.

What Is an Electrocardiogram?

An electrocardiogram, or ECG, records the electrical activity of the heart.

It can provide information about heart rhythm, conduction abnormalities, previous heart damage, and selected acute cardiac problems.

The test is non-invasive and usually takes only a few minutes.

An ECG may be performed during a routine cardiology evaluation or urgently when symptoms such as chest pain or palpitations occur.

A normal ECG does not exclude every heart condition, so additional tests may sometimes be necessary.

What Is Echocardiography?

Echocardiography uses ultrasound to create moving images of the heart.

It can assess heart chamber size, pumping function, valve movement, blood flow, and structural abnormalities.

The test is commonly used in patients with heart failure, valve disease, murmurs, or unexplained breathlessness.

Standard transthoracic echocardiography is performed from the chest wall.

Transesophageal echocardiography may be used when more detailed images of specific heart structures are required.

What Is Coronary Artery Disease?

Coronary artery disease develops when the arteries supplying the heart become narrowed or blocked.

The process is commonly associated with atherosclerosis, which causes fatty deposits to accumulate within artery walls.

Reduced blood flow can lead to chest discomfort, shortness of breath, or heart attack.

Risk factors include smoking, diabetes, high cholesterol, hypertension, obesity, and family history.

Treatment may include medication, lifestyle changes, angioplasty, stenting, or coronary bypass surgery depending on disease severity.

What Is Coronary Angiography?

Coronary angiography examines the arteries supplying blood to the heart.

During invasive angiography, a thin catheter is advanced through an artery and contrast material is injected to visualize coronary blood flow.

The test can identify narrowing or complete blockages.

In selected cases, treatment with balloon angioplasty or stent placement can be performed during the same procedure.

CT coronary angiography offers a non-invasive alternative for selected diagnostic situations.

The choice depends on symptoms, risk level, and previous test findings.

What Is Angioplasty and Stent Placement?

Coronary angioplasty is a catheter-based treatment used to open narrowed coronary arteries.

A small balloon may be inflated inside the narrowed area to improve blood flow.

A stent is often placed to help keep the artery open.

The procedure is commonly known as percutaneous coronary intervention, or PCI.

Angioplasty can be performed urgently during certain heart attacks or electively for selected coronary artery disease.

Medication remains important after stent placement to reduce clotting and manage underlying cardiovascular risk.

What Are Heart Rhythm Disorders?

Heart rhythm disorders, or arrhythmias, occur when the heart beats too fast, too slowly, or irregularly.

Examples include atrial fibrillation, supraventricular tachycardia, bradycardia, and ventricular arrhythmias.

Symptoms can include palpitations, dizziness, fatigue, shortness of breath, or fainting.

Diagnosis may require an ECG, Holter monitor, event recorder, or electrophysiological study.

Treatment can include medication, electrical cardioversion, catheter ablation, pacemaker implantation, or defibrillator therapy depending on the rhythm disorder.

What Is Catheter Ablation?

Catheter ablation is a procedure used to treat selected abnormal heart rhythms.

Thin catheters are advanced through blood vessels into the heart.

The abnormal electrical pathway or tissue causing the arrhythmia is identified through electrophysiological mapping.

Energy is then applied to modify or destroy the targeted tissue.

Radiofrequency energy and cryotherapy are among the methods used.

Catheter ablation is commonly considered for certain supraventricular tachycardias, atrial flutter, atrial fibrillation, and selected ventricular arrhythmias.

What Is Heart Failure?

Heart failure occurs when the heart cannot pump or fill efficiently enough to meet the body’s needs.

It does not mean the heart has completely stopped working.

Symptoms can include breathlessness, fatigue, reduced exercise capacity, and swelling in the legs.

Heart failure can develop because of coronary artery disease, hypertension, cardiomyopathy, valve disease, or previous heart attack.

Treatment may include medications, lifestyle changes, implanted cardiac devices, coronary procedures, valve treatment, or advanced therapies in selected cases.

What Is Heart Valve Disease?

Heart valve disease develops when one or more valves do not open or close properly.

A narrowed valve is described as stenotic, while a leaking valve causes regurgitation.

Aortic and mitral valve disorders are among the most common clinically significant valve conditions.

Echocardiography is central to diagnosis and monitoring.

Treatment depends on symptoms, valve severity, heart function, and surgical risk.

Some patients require open surgery, while others may be suitable for catheter-based valve procedures.

What Is Interventional Cardiology?

Interventional cardiology uses catheter-based procedures to diagnose and treat cardiovascular disease.

These procedures are performed through blood vessels rather than traditional open surgery.

Common interventions include coronary angioplasty, stent placement, selected structural heart procedures, and catheter-based valve treatments.

Interventional cardiology can also be used during emergency treatment for acute coronary artery blockages.

The suitability of a catheter-based approach depends on cardiovascular anatomy, disease severity, symptoms, and the overall treatment objective.

How Is High Blood Pressure Managed?

Hypertension is managed through cardiovascular risk assessment, lifestyle changes, and medication when necessary.

Persistent high blood pressure can increase the risk of heart attack, stroke, heart failure, kidney disease, and vascular complications.

Management may include reducing excessive salt intake, maintaining a healthy weight, exercising regularly, stopping smoking, and limiting alcohol.

Medication selection depends on blood pressure levels and associated medical conditions.

Regular monitoring is important because hypertension frequently causes no noticeable symptoms.

What Is Preventive Cardiology?

Preventive cardiology aims to reduce the likelihood of cardiovascular disease before serious complications develop.

Assessment may include blood pressure, cholesterol, blood glucose, body weight, smoking status, physical activity, and family history.

Patients with existing heart disease also require secondary prevention to reduce future cardiovascular events.

Treatment can include cholesterol-lowering medications, blood pressure control, diabetes management, smoking cessation, dietary improvement, and exercise.

Prevention remains important even after angioplasty or other successful cardiac procedures.

What Is Cardiac Rehabilitation?

Cardiac rehabilitation is a structured recovery program for selected patients after heart attacks, coronary procedures, heart surgery, or other cardiovascular events.

Programs may combine supervised exercise, cardiovascular education, nutritional support, risk-factor management, and psychological care.

Rehabilitation aims to improve functional capacity and reduce future cardiovascular risk.

The program is individualized according to heart function, previous treatment, physical condition, and other medical problems.

Cardiac rehabilitation complements medical treatment rather than replacing it.

Cardiology in Turkey for International Patients

International patients considering cardiology in Turkey should provide previous cardiovascular records when available.

Useful documents may include ECG results, echocardiography reports, angiography images, blood tests, medication lists, previous procedure reports, and cardiac surgery records.

Existing investigations may need to be reviewed or repeated before treatment decisions are made.

Travel planning should account for diagnostic testing, treatment, early recovery, and any restrictions after catheter-based procedures or surgery.

Cardiology in Turkey can include diagnostic testing, medical treatment, interventional cardiology, arrhythmia management, heart failure care, valve assessment, and preventive cardiology. Accurate diagnosis, cardiovascular risk management, appropriate procedure selection, and structured follow-up remain central to heart care.
