Introduction of Coronary heart disease

Coronary heart disease (CHD) is the UK’s biggest killer, causing around 82,000 deaths each year. About one in five men and one in eight women die from the disease.

In the UK, there are an estimated 2.7m people living with the condition and 2m people affected by angina (the most common symptom of coronary heart disease). 

CHD generally affects more men than women, but from the age of 50 the chances of developing CHD are similar for men and women.

As well as angina (chest pain), the main symptoms of CHD are heart attacks and heart failure. However, not everyone has the same symptoms and some people may not have any before CHD is diagnosed.

CHD is sometimes called ischaemic heart disease.

About 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 organs of your body 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 surface of your heart, called coronary arteries.

Why does coronary heart disease happen?

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 habits and other conditions, such as:
