Coronary Heart Disease (CHD) is, by far, the most common cardiovascular condition. It is also known as 'Ishaemic Heart Disease'. Heart disease amounts to 26% of all deaths in western society. It is most common with people over 50 but can occur in the younger generation. This report intends to look into cardiovascular diseases and their causes. Its purpose is to ascertain any similarities in the range of cardiovascular conditions and also to understand the exact nature of this named cardiovascular disease - Coronary Heart disease. In addition the potential risk factors will be evaluated and treatments explained.


The underlying causes of heart disease are:

q An insufficient supply of blood to the heart.

The coronary arteries narrow, due to the build up fatty deposits, called artheramas. These reduce the blood supply to the heart and sometimes block it completely. The result can be minor chest pains, but could also result in a fatal heart attack.

This is known as Coronary heart disease. People who suffer from CHD have at least one or more common factors, for example: high blood cholesterol, high blood pressure, smoking, diabetes and genetic inheritance which makes them more likely to suffer from heart disease.
