what is coronary heart disease (CHD)
when coronary arteries that supply the blood to the heart muscle get blocked by layers of fatty material building up. this causes arteries to become narrow, so blood flow is restricted and there’s a lack of oxygen going to the heart muscle
what are the risk factors for CHD?
- a diet high in saturated fat - can lead to fatty deposits forming in arteries
- smoking
- being inactive - can lead to high blood pressure, damaging artery lining.
