Association Between Short-Term Simvastatin Therapy Before Coronary Artery Bypass Grafting and Postoperative Myocardial Blood Flow as Assessed by Positron Emission Tomography M. Imran Dotani, MD, Anthony P. Morise, MD, Reyaz Haque, MD, Abnash C. Jain, MD, Naresh Gupta, MD, and C. Michael Gibson, MS, MD A previous retrospective study demonstrated im- proved outcomes associated with short-term (3 to 5 days) preoperative statin treatment in patients who underwent coronary artery bypass grafting (CABG). 1 In light of this observational data, we believed that a prospective study of preoperative statin therapy was warranted. We hypothesized that preoperative simva- statin therapy would be associated with improvements in myocardial perfusion on positron emission tomog- raphy (PET) scanning above and beyond what may be expected strictly from the placement of bypass con- duits. ••• Patients with known 3-vessel coronary artery dis- ease diagnosed by coronary angiography, scheduled for elective CABG surgery, and who were willing to undergo pre- and postoperative PET scanning were considered for the study. Exclusion criteria included unstable angina or myocardial infraction with an ur- gent or emergency requirement for surgery, secondary hypercholesterolemia due to conditions such as hypo- or hyperthyroidism, malignancy within 5 years except basal cell carcinoma, active liver disease or hepatic dysfunction, current use of cyclosporin, oral contra- ceptives, or other p-450 enzyme inhibitors, current use of cholesterol-lowering medications, and drug and/or alcohol abuse. The study was approved by the insti- tutional review board at West Virginia University Hospital. Between April 2001 and February 2002, 10 pa- tients were randomized in a double-blind fashion to either placebo or simvastatin 40 mg/day. All patients received simvastatin or placebo therapy for 14 2 days, with therapy 4 1 days before CABG and 10 1 days after CABG. All patients were discharged From the Beth Israel Deaconess Medical Center, Boston, Massachu- setts; and West Virginia University Hospitals, Morgantown, West Virginia.
