How can CHD be prevented?

Becoming more active, eating a healthy diet and stopping smoking can make a tremendous difference to the health of your heart.

Who is most at risk?

Scientists have yet to unravel all of the causes of heart disease. However, some people are particularly predisposed towards developing atherosclerosis, due to inherited genetic factors. They may have a family history of people dying at a young age from CHD. However, an unhealthy diet, lack of exercise, diabetes, high blood pressure and smoking all increase the risk of CHD and all of these can be addressed.

What about a heart attack?

Unfortunately, for many people the first indication that something is wrong is a heart attack. This happens when the blood supply to part of the heart muscle is completely interrupted or stops, usually when a blood clot forms in a diseased coronary artery that has already become narrowed by atherosclerosis.

What are the key symptoms of CHD?

The main symptom is a feeling of heaviness, tightness or pain in the middle of your chest that may extend to, or just affect, your arms (especially the left), neck, jaw, face, back or abdomen. This is referred to as angina, and is caused by insufficient oxygen reaching the heart muscle because of reduced blood flow.

What is CHD?

In CHD, the arteries that supply the heart with oxygen and nutrients become furry and narrowed, which is referred to as atherosclerosis. This restricts the supply of blood and oxygen to the heart, particularly during exertion when there are more demands on the heart muscle.
