Coronary heart disease (CHD) is a major cause of death in the UK and worldwide. CHD is sometimes called ischaemic heart disease or coronary artery disease.
If you have heart disease and you're worried about coronavirus, you can get advice about coronavirus and heart disease from the British Heart Foundation.
The main symptoms of coronary heart disease are:
- chest pain (angina)
- shortness of breath
- pain throughout the body
- feeling faint
- feeling sick (nausea)
But not everyone has the same symptoms and some people may not have any before coronary heart disease 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, such as smoking and regularly drinking excessive amounts of alcohol.
Diagnosing coronary heart disease (CHD)
If a doctor feels you're at risk of coronary heart disease, they may carry out a risk assessment.
They'll ask you about your medical and family history and your lifestyle, and they'll take a blood test.
Further tests may be needed to confirm coronary heart disease, including:

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.
