Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Rosuvastatin 40mgs orally at 36 hours and 12 hours pre CABG and then rosuvastatin 40 mgs daily for 7 days post CABG.
Intervention code [1] 286253 0
Treatment: Drugs
Comparator / control treatment
The control group will receive standard care as per normal clinical practice for the treatment of CABG patients which will include being prescribed a medication from the statin group but not at as large a dose as this would have precluded them from being randomised into the study.
Control group
Active

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 bypass surgery is done. 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.
