A cardiac clinic is reviewing its policy for adults with coronary heart disease who report chest pain. The clinic is deciding whether to offer a stent together with statins as the initial treatment, or to begin with statins only.
A study followed 120 patients receiving each policy for six months.
| Outcome after six months | Statins only | Stent and statins |
|---|---|---|
| Patients still reporting chest pain | 72 | 30 |
| Patients who had a heart attack | 12 | 5 |
| Patients who developed a blood clot on a stent | Not applicable | 8 |
Evaluate the two policies.
