The effects of prior use of atorvastatin on coronary blood flow after primary percutaneous coronary intervention in patients presenting with acute myocardial infarction Celik T, et al. Coronary Artery Disease 2005 Only mean TIMI frame count was detected to be significantly lower in patients taking at least 40mg. Atorvastatin for at least 6 months compared with that of the patients taking no statin (p < 0.001). After confounding variables were controlled for, the mean TIMI frame count of patients in group 2 was significantly lower than that of the patients in group 1 (p = 0.001). Backgrounds
Although statin prior to PCI has favorable effects in stable angina and ACS except ST elevation MI (STEMI), there have have been few studies for STEMI. Celik T et al. reported in patients with STEMI that prior statin use may improve coronary blood flow after PCI in patients with AMI. But this study was retrospective, nonrandomized study and evaluated the effects for chronic statin therapy no acute high dose effect. The effects of prior use of atorvastatin on coronary blood flow after primary percutaneous coronary intervention in patients presenting with acute myocardial infarction
Hypothesis We investigate whether acute high-dose statin prior to primary PCI can have beneficial effect or not for periprocedural period and 30 days-cardiac events.
Inclusion Criteria The patient must be at least 18-80 years of age. The patient had the symptoms of acute myocardial infaction within 12 hours with ST segment elevation of more than 1 mm in at least two contiguous leads of EKG or new onset LBBB. The patient or guardian agrees to the study protocol a nd provides informed, written consent.
Patients with any of the following will be excluded from participation: Patients to whom PCI can not be undergone within 12 hours from receiving the study drug Cardiogenic shock or symptomatic hypotension or sitting SBP < 95 mmHg The history of major surgery, trauma, retinal hemorrhage, significant gastrointestinal or genitourinary bleeding within recent 6 weeks; history of cerebrovascular attack within two years, or cerebrovascular attack with a significant residual neurological deficit Severe or malignant hypertension (= sitting SBP > 180 mmHg and/or sitting DBP > 105 mmHg) The history or diagnosis of vasculitis; renal insuffiency (the level of serum creatinine is two times higher than the upper limit of normal of each center) The patients who might die of other disease than cardiac disease during the trial. Exclusion Criteria
Primary End-Point To evaluate the effect of high-dose Atorvastatin (started at emergency room) in STEMI –30 Days MACE (Death, non-fatal MI, TVR)
Secondary End-Point - Corrected TIMI frame count - Myocardial blush grade after PCI - ST resolution at 90 minutes - MACE at 9 months

Conclusion The loading of high dose atorvastatin did not decrease the MACE but improve the immediate coronary flow after primary PCI. Therefore, it might be helpful for achieving the optimal results for primary PCI in STEMI through the beneficial effects on microvascular function.
