Poor diet (eating too much fat)
Stress (increased blood pressure)
Smoking (increased blood pressure)
Age (risk increases as you get older)
Gender (males more likely) 
Genetic predisposition

Question 3

Prevention:

Answer 3

Diet- low-fat, high-fibre diet, fruits and vegetables and whole grains.
Regular exercise- lowers cholesterol levels and keeps blood pressure at a healthy level.

Question 4

Treatments:

Answer 4

Aspirin- eases inflammation-this can prevent a heart attack or stroke and prevents blood clots.

Question 5

Surgery:

Answer 5

Angioplasty- inserting a short wire-mesh tube, called a stent, into a blocked or narrowed artery; the stnet helps the blood flow easily.
By-pass- Diverts blood around narrowed or clogged parts of the major arteries to improve blood flow and oxygen supply to the heart.

Question 6

complete blockage

Answer 6

means cells in that area of the heart will not be able to respire and can no longer contract, leading to a heart attack

Question 7

Partial blockage

Answer 7

Partial blockage of the coronary arteries creates a restricted blood flow to the cardiac muscle cells and results in severe chest pains called angina

Question 8

what leads to CHD

Answer 8

If a coronary artery becomes partially or completely blocked by fatty deposits called ‘plaques’ (mainly formed from cholesterol), the arteries are not as elastic as they should be and therefore cannot stretch to accommodate the blood which is being forced through them – leading to coronary heart disease
