Coronary heart disease
Coronary heart disease (CHD) is a major cause of death worldwide.
It's responsible for more than 73,000 deaths in the UK each year. About 1 in6 men and 1 in10 women die from CHD.
In the UK, there are an estimated 2.3 million people living with CHD and around 2 million people affected by Angina (the most common symptom of coronary heart disease).
CHD generally affects more men than women, althoughfrom the age of 50 the chances of developingthe conditionare similar for both sexes.
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.
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.
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:

Classification of heart diseases
If your doctor thinks you may be at risk of developing CHD, they may carry out a risk assessment for cardiovascular disease, myocardial infarction or stroke . This may be carried out as part of a health check.
Although coronary heart disease (CHD) cannot be cured, treatment can help manage the symptoms and reduce the risk of further problems. If you have been diagnosed with CHD, you can reduce your risk of further episodes by making simple lifestyle changes.
After having heart surgery or problems like a heart attack, it is possible to resume a normal life. If you have heart surgery, a member of the cardiac rehabilitation team may visit you in hospital to give you information about your condition and the procedure you are having.
There are several ways you can help lower your risk of developing coronary heart disease (CHD), such as reducing your blood pressure and cholesterol levels. You should limit the amount of salt you eat to no more than 6g (0.2oz) a day, as too much salt will increase your blood pressure.
