Coronary heart disease (CHD) is a cardiovascular disease. In CHD, fatty deposits build up inside the coronary arteries.
The Table shows information about three treatments for CHD.
Table
| Treatment | Cost to the health service in the first year in £ | Time taken to have an effect | Risks |
|---|---|---|---|
| lifestyle changes, such as a healthier diet and more exercise | 0 | several months | none |
| statins (a medicine that lowers blood cholesterol) | 50 | several weeks | side effects such as muscle pain; must be taken for life |
| stent fitted by surgery | 5000 | immediately | infection or a blood clot after surgery; the artery can narrow again |
CHD is a non-communicable disease caused by the interaction of a number of factors.
Give two risk factors for CHD.
Explain how a stent treats CHD.
A patient has a coronary artery that is badly blocked.
Evaluate the treatments in the Table for this patient.
