Experiences with
Coronary heart disease
Coronary heart disease (CHD) is a major cause of death both in the UK and worldwide. CHD is sometimes called ischaemic heart disease or coronary artery disease.
The main symptoms of CHD are:
- chest pain (angina)
- heart attacks
- heart failure
You can also experience other symptoms, such as heart palpitations and unusual breathlessness.
But not everyone has the same symptoms and some people may not have any before CHD is diagnosed.
Coronary heart disease is the term that describes what happens when your heart's blood supply is blocked or interrupted by a build-up of fatty substances in the coronary arteries.
Over time, the walls of your arteries can become furred up with fatty deposits.
This process is known as atherosclerosis and the fatty deposits are called atheroma.
Atherosclerosis can be caused by lifestyle factors and other conditions, such as:
Diagnosing coronary heart disease (CHD)
If your doctor feels you're at risk of CHD, they may carry out a risk assessment.
This involves asking about your medical and family history, your lifestyle and taking a blood test.
Further tests may be needed to confirm a diagnosis of CHD, including:
- a treadmill test
- a radionuclide scan
- a CT scan
- an MRI scan
- coronary angiography

Coronary heart disease cannot be cured but treatment can help manage the symptoms and reduce the chances of problems, such as heart attacks.
Treatment can include:
- lifestyle changes, such as regular exercise and stopping smoking
- medicines
- angioplasty, where balloons and stents are used to treat narrow heart arteries
- surgery
Recovering from the effects of coronary heart disease (CHD)
If you have a heart attack or have had angioplasty or heart surgery, it's possible to eventually resume a normal life.
Advice and support is available to help you deal with aspects of your life that may have been affected by CHD.

You can reduce your risk of getting CHD by making some simple lifestyle changes.
These include:
- eating a healthy, balanced diet
- being physically active
- giving up smoking
- controlling blood cholesterol and sugar levels
Keeping your heart healthy will also have other health benefits, such as helping reduce your risk of stroke and dementia.
The heart
The heart is a muscle about the size of your fist. It pumps blood around your body and beats approximately 70 times a minute.
After the blood leaves the right side of the heart, it goes to your lungs where it picks up oxygen.
The oxygen-rich blood returns to your heart and is then pumped to the body's organs through a network of arteries.
The blood returns to your heart through veins before being pumped back to your lungs again. This process is called circulation.
The heart gets its own supply of blood from a network of blood vessels on the heart's surface called coronary arteries.
