Summary
Brief summary
The primary purpose of the study is to ascertain whether giving high doses of a cholesterol lowering drug (statin) can reduce the amount of damage caused to the heart by having a lack of oxygen and then having blood restored to the heart quickly when the blocked artery is opened by the insertion of a stent. Tissue damage may be caused when the supply of oxygen is restored to the heart. There are sound biological reasons but limited data that shows that by giving a high dose of a statin drug it is believed that the injury to the heart may be lessened and that incidences of heart failure caused by the heart attack may be lessened.
