Cardiology

Cardiology is the medical specialty concerned with the detection, evaluation, treatment, and long-term care of diseases of the heart and vascular system. The aim of a cardiology consultation is the early identification of heart diseases, the assessment and reduction of cardiovascular risk factors, and the safe treatment and follow-up of existing conditions.

A cardiology examination is particularly important:

• in case of symptoms,
• when increased risk is present,
• for preoperative risk assessment,
• and in treatments that may affect the heart muscle (e.g., chemotherapy, radiation therapy).

Cardiovascular diseases are often asymptomatic in their early stages, therefore regular cardiology check-ups are one of the most important tools for prevention.

When should you see a cardiologist?

• intermittent or exertion-related chest pain or pressure
• palpitations, irregular heartbeat
• shortness of breath
• reduced exercise capacity and performance
• dizziness or fainting
• high blood pressure or difficulty controlling it
• swelling of the lower limbs (leg edema)
• recurrent, unexplained fatigue

Even without symptoms, cardiology screening is recommended—especially in high-risk cases.

Screening is advised even without complaints if:

• there is a family history of early-onset heart disease
• in case of smoking, overweight, or a sedentary lifestyle
• during prolonged periods of stress
• before starting a new sport or exercise program
• prior to non-cardiac surgery for cardiovascular risk assessment

What is assessed during a cardiology consultation?

During the examination, the function of the heart and vascular system and the individual cardiovascular risk are evaluated. The goal is to clarify the cause of symptoms and detect any abnormalities early.

The evaluation may focus on detecting:

• cardiac arrhythmias and conduction disorders
• coronary artery disease (impaired blood supply to the heart muscle)
• hypertension and its complications
• heart failure
• valvular heart diseases
• abnormalities affecting the heart muscle (e.g., due to medications or oncological treatments)

How does a cardiology consultation proceed?

Medical history (anamnesis):

• detailed review of symptoms
• previous illnesses and surgeries
• family medical history
• current medications
• lifestyle factors
• review of recent lab results (if unavailable, the physician may request tests to assess lipid profile, glucose metabolism, kidney function, uric acid levels)

Physical and basic examinations:

• physical examination
• resting ECG
• blood pressure measurement
• laboratory tests (if needed, including lipoprotein(a), metabolic parameters, thyroid function, or hormonal tests in hypertension evaluation)

Additional tests (if necessary):

Based on symptoms, risk factors, and initial findings, further targeted examinations may be recommended, such as:

• cardiac ultrasound (echocardiography)
• exercise ECG (stress test)
• 24-hour Holter ECG monitoring
• 24-hour ambulatory blood pressure monitoring (ABPM)
• preoperative cardiac assessment
• lower limb arterial Doppler ultrasound
• venous duplex ultrasound (e.g., in suspected pulmonary embolism)
• carotid artery duplex ultrasound

Following appropriate evaluation and indication, coronary CT angiography or cardiac MRI may also be performed.

Treatment and follow-up

Based on the results, the cardiologist determines the necessary medical or non-medical treatment and the frequency of follow-up visits.

Cardiology care includes long-term management, aiming to reduce symptoms, stabilize the condition, and prevent complications.

This may include:

• regular follow-up examinations
• adjustment of medication therapy
• lifestyle counseling and non-pharmacological interventions (exercise programs, weight reduction, smoking cessation support)

When is follow-up necessary?

• in case of new or worsening symptoms
• after starting or modifying medication
• during management of chronic heart disease
• when monitoring hypertension or arrhythmias
• before or after surgical procedures, based on medical advice

Why is regular cardiology follow-up important?

With appropriate lifestyle changes, regular monitoring, and timely treatment, many cardiovascular diseases can be prevented or their progression slowed. Regular cardiology examinations help detect hidden abnormalities before symptoms appear, reducing the risk of serious complications.

Frequently Asked Questions – Cardiology

When should I first see a cardiologist?
A consultation is recommended even without symptoms if there is a family history of heart disease, high blood pressure, or if you smoke, are overweight, or have a sedentary lifestyle. In case of symptoms (e.g., chest pain, palpitations), evaluation is advised as soon as possible.

Is preparation required before the examination?
Usually no special preparation is needed. It is recommended to bring previous medical records and a list of current medications.

Are cardiology tests painful?
No. Basic cardiology tests (ECG, blood pressure measurement, echocardiography) are painless. Exercise ECG involves physical exertion but is performed under continuous medical supervision.

How long does a cardiology consultation take?
A basic visit usually takes 20–30 minutes. Additional tests may extend the duration.

Is medication alone enough for high blood pressure?
Lifestyle modifications (weight loss, regular exercise, reduced salt intake, stress management) are also essential alongside medication.

Can I exercise if I have heart-related symptoms?
Yes, but only after cardiological evaluation. The specialist will determine the appropriate type and intensity of exercise.

How often are follow-up visits needed?
This depends on the condition and treatment. In chronic heart disease or hypertension, regular follow-up (typically every 6–12 months) is recommended.

Do you perform preoperative cardiac assessments?
Yes, cardiology risk assessment is often required before surgery to ensure safe procedures.
