Consider consulting a cardiologist if you experience persistent chest discomfort, breathlessness, palpitations, dizziness, fainting, unusual fatigue or swelling in your legs or feet. A specialist evaluation may also be appropriate if you have high blood pressure, high cholesterol, diabetes, a strong family history of heart disease or abnormal cardiac test results. If symptoms such as severe chest pain, significant breathing difficulty or fainting occur suddenly, seek emergency medical care rather than waiting for a routine cardiology appointment.

The tests recommended depend on your symptoms, medical history and suspected heart condition. Common investigations include blood tests, an electrocardiogram (ECG), echocardiogram, Holter monitoring and exercise or stress testing. Doctors may also recommend chest X-rays, cardiac CT, cardiac MRI or cardiac catheterization when more detailed information is needed. These tests can assess heart rhythm, structure, function and blood flow and help the cardiologist identify the cause of symptoms and determine the appropriate treatment.

A cardiologist diagnoses and manages a wide range of cardiovascular conditions. These can include coronary artery disease, heart failure, abnormal heart rhythms, heart valve disease, diseases of the heart muscle and certain congenital heart conditions. Cardiologists also help manage cardiovascular risk factors such as high blood pressure and high cholesterol. Depending on the condition, treatment may involve lifestyle changes, medicines, monitoring or specialised procedures. Some patients may require care from an interventional cardiologist or cardiac surgeon.

Treatment depends on the type of heart condition, its severity and the extent of heart damage. Options may include lifestyle changes, medicines, minimally invasive procedures and surgery. For coronary artery disease, treatment may involve medicines and lifestyle changes, while some patients may require angioplasty with stent placement or coronary artery bypass surgery. A cardiologist considers symptoms, test results, overall health and other risk factors before recommending the most appropriate treatment approach.

You can support your heart health by eating a balanced diet rich in vegetables, fruits and whole grains while limiting excess salt, sugar and saturated fats. Regular physical activity, maintaining a healthy weight and avoiding tobacco are also important. Managing blood pressure, cholesterol and diabetes can further reduce cardiovascular risk. Regular health check-ups can help identify risk factors early. If you already have a heart condition, follow your healthcare professional's advice regarding medicines, diet, exercise and follow-up care.

You can ask what may be causing your symptoms, which tests you need and what the results could indicate. If a heart condition is diagnosed, ask about its severity, available treatment options and what changes you can make to protect your heart. You may also want to discuss medicines, physical activity, diet, warning signs that require urgent attention and follow-up requirements. Carry previous reports, ECGs, scans, blood test results and a list of your current medicines to help the cardiologist understand your medical history.
