Key Stage 4
Meaning
Coronary Heart Disease is a non-communicable disease in which the arteries that supply the heart with oxygen become narrower because of the build up of cholesterol plaques.
About Coronary Heart Disease
- Coronary Heart Disease can lead to a heart attack.
- A Cholesterol plaque is a lump of fat.
Risk Factors in Coronary Heart Disease
- Obesity and a diet high in fat can increase the risk of Coronary Heart Disease.
- Smoking can increase the risk of Coronary Heart Disease.
- Lack of exercise can increase the risk of Coronary Heart Disease.
Treatment of Coronary Heart Disease
- In a Coronary Bypass an artery from another part of the body is cut out and attached to the Coronary Artery to provide a path for blood to flow around the blockage.
- A Stent is a tube which can be placed inside the narrow artery and then expanded to widen the artery. The Stent is left inside the artery to hold it open.
