Cardiology

What is Cardiology?

Cardiology is a medical specialty within internal medicine focused on the diagnosis, treatment, and prevention of diseases of the heart and blood vessels.

A cardiologist provides medication-based treatment and performs catheter-based procedures, while a cardiothoracic surgeon performs heart surgery.

When should you consult a cardiologist?

A consultation with a cardiologist is recommended if you experience:

• Chest pain or pressure
• Palpitations
• Shortness of breath on exertion
• Dizziness, fainting, or swelling of the legs

Additionally, high blood pressure, shortness of breath, and fatigue during normal activities may indicate the need for cardiac evaluation.

Heart disease can sometimes be silent, with subtle symptoms such as fatigue, nausea, or discomfort in the back or neck, especially in women, older adults, and people with diabetes.

How to prepare for a cardiology appointment?

Good preparation helps ensure accurate diagnosis and effective treatment:

1. Collect your medical documentation
   Bring previous ECG, echocardiography, laboratory results, imaging, and discharge summaries from prior hospitalizations or surgeries. If you have a pacemaker or ICD, bring the device identification card.
2. Make a list of your medications
   Include all drugs, supplements, and herbal products.
3. Track your symptoms
   Note when they occur and whether they change with activity or rest.
4. Follow testing instructions
   • Do not stop medications unless your doctor instructs you to.
   • Continue your usual therapy unless advised otherwise.
5. Prepare your questions
   Ask about diagnosis, treatment options, risks, and prevention.
6. Bring a companion if needed for support.

What happens during the appointment?

The visit typically begins with a detailed discussion of symptoms, chest pain, shortness of breath, palpitations, fatigue, dizziness, along with personal and family medical history and lifestyle factors.

A physical examination follows:

• Measurement of blood pressure and pulse
• Cardiac auscultation with a stethoscope
• Inspection for edema and other physical signs

An electrocardiogram (ECG) is routinely performed, and if necessary, additional tests such as echocardiography, Holter monitoring, or laboratory tests may be ordered.

Finally, the cardiologist reviews the results and develops a personalized treatment plan, preventive strategy, and follow-up recommendations.
