Another Commonly Asked Question From People Online Is, What Does a Cardiologist Actually Do?
When it comes to heart health, a cardiologist is the expert you’ll turn to for diagnosis, treatment, and management of heart-related conditions. As specialists in the cardiovascular system, cardiologists deal with everything from preventative care and screenings to managing complex heart conditions. But what exactly does a cardiologist do? I’ll walk you through the role of a cardiologist, the conditions they treat, and how they can help improve your heart health.
What Does a Cardiologist Specialise In?
Cardiologists are doctors who specialise in diagnosing and treating diseases of the heart and blood vessels, collectively known as cardiovascular diseases. These include conditions such as coronary artery disease, heart failure, arrhythmias (irregular heart rhythms), and issues with the heart valves.
A significant part of a cardiologist’s job is to assess heart function using various tests and tools, helping them diagnose problems early and develop a treatment plan. Cardiologists also focus on managing risk factors like high blood pressure, high cholesterol, and diabetes, which can contribute to the development of heart disease.
What Happens During a Visit to a Cardiologist?
When you see a cardiologist, the first step is usually a detailed assessment of your medical history, symptoms, and lifestyle. Cardiologists take a comprehensive approach to understanding your heart health. During your appointment, they may ask about:
Any symptoms like chest pain, shortness of breath, or palpitations
Your family history of heart disease
Your lifestyle habits, such as smoking, exercise, and diet
Risk factors like high blood pressure or diabetes
Once your cardiologist has a clear understanding of your overall health, they might recommend certain diagnostic tests to get a closer look at how your heart is functioning. These tests could include:
Electrocardiogram (ECG): A simple test that records the electrical activity of your heart to detect rhythm problems.
Echocardiogram: An ultrasound of the heart that allows your cardiologist to examine the heart’s structure and function.
Stress Tests: These involve monitoring your heart’s activity while you exercise, helping to identify how well your heart functions under stress.
Blood Tests: These can help identify markers of heart disease or other conditions affecting heart health.
Angiogram: This is a more invasive test, usually recommended if there's a suspicion of blocked arteries, where dye is injected into the arteries to highlight any blockages on an X-ray.
Common Conditions Cardiologists Treat
Cardiologists are trained to manage a wide range of heart conditions. Some of the most common conditions they treat include:
Coronary Artery Disease: This occurs when the blood vessels that supply the heart become narrowed or blocked, often leading to chest pain (angina) or even heart attacks. Cardiologists can help manage this through lifestyle changes, medications, or procedures like angioplasty.
Heart Failure: When the heart is unable to pump blood effectively, it can lead to symptoms like shortness of breath, fatigue, and swelling. Cardiologists can help by prescribing medications or recommending lifestyle adjustments to manage heart failure.
Arrhythmias: These are problems with the heart’s rhythm, such as atrial fibrillation (AF), where the heart beats irregularly or too fast. Cardiologists can use medications, electrical devices like pacemakers, or other procedures to correct abnormal rhythms.
Heart Valve Disorders: When heart valves don’t open or close properly, it can lead to issues such as regurgitation (leaking) or stenosis (narrowing). Cardiologists may monitor these conditions or recommend surgical intervention if needed.

How Cardiologists Help Prevent Heart Disease
Prevention is a key focus for cardiologists. Heart disease often develops slowly over time, and many risk factors can be managed with the right approach. Cardiologists work with patients to identify and reduce these risks through:
Lifestyle Modifications: Cardiologists often provide guidance on improving diet, exercise, and other lifestyle habits. Quitting smoking, maintaining a healthy weight, and incorporating regular physical activity are crucial for reducing the risk of heart disease.
Medication Management: For conditions like high blood pressure or high cholesterol, cardiologists may prescribe medications to manage these risk factors. Keeping these conditions under control can prevent complications like heart attacks or strokes.
Regular Monitoring: For patients with known heart conditions or at high risk, cardiologists will often set up regular check-ups to monitor heart function and ensure any problems are detected early.
What Types of Procedures Do Cardiologists Perform?
While cardiologists primarily diagnose and manage heart conditions, some also perform procedures to treat certain problems. Here are a few examples:
Angioplasty and Stent Placement: If an artery is blocked or narrowed, a cardiologist may perform an angioplasty to open it up and insert a stent, a small tube that keeps the artery open.
Pacemaker or Defibrillator Implantation: For patients with abnormal heart rhythms, a cardiologist may recommend implanting a pacemaker or defibrillator to regulate the heartbeat.
Cardiac Ablation: In cases of arrhythmia, ablation involves using radiofrequency energy to destroy the tissue that’s causing the abnormal heart rhythm.
Not all cardiologists perform these procedures—some may refer you to an interventional cardiologist or surgeon for more invasive treatments. Your cardiologist will work with you to determine the best approach based on your condition.
When Should You See a Cardiologist?
If you have risk factors for heart disease, such as high blood pressure, high cholesterol, or a family history of heart conditions, it’s a good idea to schedule a visit with a cardiologist. You should also seek out a cardiologist if you experience symptoms like chest pain, shortness of breath, or palpitations.
Even if you’re not experiencing any symptoms, regular check-ups with a cardiologist can be helpful in preventing future heart problems, particularly if you have a strong family history of heart disease. Early detection is often key to effective treatment, so don’t hesitate to make an appointment if you have concerns about your heart health.
For more advice on when to see a cardiologist, the NHS provides useful guidelines on maintaining heart health and when to seek medical attention.
Conclusion
A cardiologist’s role is vital in diagnosing, treating, and preventing heart disease. Whether you’re managing an existing heart condition or taking steps to reduce your risk, a cardiologist will work with you to keep your heart healthy. From performing diagnostic tests to managing ongoing treatment, cardiologists play a crucial part in ensuring long-term heart health.
