Coronary Artery Disease

What is Coronary Artery Disease?

Coronary artery disease (CAD) is a common heart condition where the arteries that supply blood to your heart muscle become narrowed or blocked. This is usually caused by the build-up of atherosclerotic plaques, which are made up of cholesterol, fatty deposits, and calcium.

As the arteries become narrower, blood flow to the heart is reduced. This can cause chest pain (angina) or, in more serious cases, a heart attack (also known as a myocardial infarction).

At London Heart Group, our leading private cardiologists in London offer expert diagnosis, risk assessment, and personalised treatment plans for coronary artery disease using the latest diagnostic and interventional techniques.

What Are the Symptoms of Coronary Artery Disease?

Coronary artery disease can develop gradually over time without any symptoms. When symptoms do appear, they can vary widely between individuals. The most common symptoms include:

  • Chest pain or discomfort (angina) – often described as pressure, heaviness, or burning

  • Pain that may spread to the shoulders, arms, neck, jaw, back, or upper abdomen

  • Shortness of breath, especially during physical activity

  • Fatigue, dizziness, or nausea

These symptoms are often triggered by physical exertion or emotional stress and may improve with rest. Some people may not notice any signs of coronary artery disease until they experience a heart attack.

What Causes Coronary Artery Disease?

Coronary artery disease develops when plaque builds up inside the arteries – a process called atherosclerosis. Several key risk factors increase the likelihood of developing CAD, including:

  • Age and gender

  • Smoking

  • High blood pressure (hypertension)

  • High cholesterol

  • Diabetes

  • Obesity

  • Lack of exercise

  • A family history of heart disease

By addressing risk factors you can control early, you can significantly reduce your risk of complications such as heart attack or stroke.

How is Coronary Artery Disease Diagnosed?

At London Heart Group, our consultants use a combination of clinical expertise and cutting-edge diagnostics to detect and assess coronary artery disease. Diagnosis may involve:

  • A detailed review of your symptoms and medical history

  • Risk factor evaluation (e.g. family history, high cholesterol, diabetes)

  • Advanced imaging, including CT coronary angiography, stress testing, or coronary functional assessment

  • Personalised risk modelling to guide prevention and treatment

Whether you are experiencing symptoms or seeking proactive screening due to a strong family history, we provide a thorough and accurate evaluation.

How is Coronary Artery Disease Treated?

The goal of treatment is to relieve symptoms, prevent heart attacks, and improve long-term heart health. Our approach is tailored to your individual needs and may include:

Lifestyle Changes

  • Heart-healthy diet

  • Regular exercise

  • Smoking cessation

  • Weight management

Medication

  • To control blood pressure, cholesterol, and blood sugar

  • To improve blood flow and reduce the risk of blood clots

  • To relieve angina symptoms

Advanced Treatment Options

If lifestyle changes and medication are not enough to control your symptoms, we may recommend revascularisation procedures, such as:

  • Percutaneous Coronary Intervention (PCI) – also known as coronary angioplasty and stenting

  • Treatment of complex cases including multi-vessel disease and chronic total occlusions (CTO)

  • Mechanical circulatory support, when necessary

Our consultants are recognised experts in complex coronary interventions and are happy to provide second opinions for patients seeking clarity on their treatment options.
