Coronary heart disease

Also called CHD, Coronary artery disease, or Ischaemic heart disease

Coronary heart disease is when the arteries that supply blood to the heart muscle become narrowed by fatty deposits. This can cause chest pain (angina) and, if an artery becomes blocked, a heart attack. It is one of the most common causes of death, but the risk can be greatly reduced.

What it is

Smoking, high blood pressure, high cholesterol, diabetes, inactivity, being overweight and a family history all raise the risk.

Treatment includes lifestyle changes, medicines such as statins, aspirin and blood pressure tablets, and procedures to open or bypass narrowed arteries (stents or bypass surgery). Cardiac rehabilitation helps recovery after a heart attack.

Common signs

  • Chest pain or tightness on exertion (angina)
  • Breathlessness
  • Pain spreading to the arm, neck, jaw or back
  • Feeling faint or sick
  • Sometimes no symptoms before a heart attack

How it is usually diagnosed

  • ECG and blood tests
  • Exercise testing
  • CT coronary angiogram
  • Coronary angiography
  • Echocardiogram

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • ECG and angiogram reports
  • Details of any stents or bypass grafts and their dates
  • Cholesterol and blood pressure results
  • Your list of medicines
  • Cardiac rehabilitation notes

Questions to ask your doctor

  • How narrowed are my arteries, and do I need a procedure?
  • What should I do if I get chest pain?
  • Can I join cardiac rehabilitation?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Chest pain that does not go away after a few minutes of rest or with your GTN spray, especially with sweating, sickness or breathlessness: call 112
