What Is A Cardiologist?
A cardiologist is a medical doctor who specialises in diagnosing and treating diseases of the cardiovascular system, including the heart, arteries, and veins. Importantly, cardiologists do not perform surgery. Instead, they use non-invasive or minimally invasive methods such as:
- Echocardiograms
- Stress tests
- Electrocardiograms (ECG)
- Cardiac catheterisations
- Prescription medications
- Lifestyle and risk factor management
They manage conditions like high blood pressure, arrhythmias, heart failure, coronary artery disease, and high cholesterol. If a cardiologist determines that surgery is needed, they will refer you to a cardiothoracic surgeon.

What Does A Cardiothoracic Surgeon Do?
A cardiothoracic surgeon is a specialist who performs surgery on the heart, lungs, oesophagus, and other organs within the chest cavity. This includes complex and life-saving procedures such as:
- Coronary artery bypass grafting (CABG)
- Heart valve repair or replacement
- Lung resections for cancer
- Surgery for congenital heart defects
- Surgical treatment of thoracic trauma or tumours
Cardiothoracic surgeons undergo extensive training that includes general surgery followed by specialised training in thoracic and cardiac procedures.

When Should You See A Cardiologist?
You should consult a cardiologist if you experience:
- Chest pain or discomfort
- Shortness of breath
- Irregular heartbeat (arrhythmia)

Cardiologists help detect problems early and can prevent the need for surgery through early intervention.

Your cardiologist or physician may refer you to a cardiothoracic surgeon if:
- You need bypass surgery or valve replacement
- You are diagnosed with a thoracic tumour or lung cancer
- You have a congenital heart defect requiring correction
- A cardiac device or structural repair is needed surgically
