Treating cardiovascular diseaseSpec 5.25
Cardiovascular disease is disease of the heart or blood vessels. In an evaluate question you must give advantages and disadvantages of each treatment, then reach a conclusion.
| Treatment | Advantages | Disadvantages |
|---|---|---|
| Life-long medication, for example statins to lower cholesterol, or drugs that lower blood pressure or stop blood clotting | Reduces risk; no operation needed; can be effective for many years | Must be taken every day for life; possible side effects; ongoing cost; may be forgotten |
| Surgical procedures, for example stents, bypass surgery, valve replacement or a heart transplant | Can quickly restore blood flow or heart function; effective for serious cases | Risks of surgery such as infection and bleeding; recovery time; cost; a transplant needs a donor and may be rejected |
| Lifestyle changes, such as stopping smoking, eating a balanced diet and exercising | Cheap; no side effects; also reduces the risk of other diseases | Needs long-term effort; results take time; not enough alone for severe disease |
The best choice depends on the patient. Lifestyle changes are suitable for most people to reduce risk. Medication is used to manage existing disease. Surgery is usually used when disease is severe or has caused a blockage.
