    ObjectivesThis study sought to determine the efficacy of high-dose atorvastatin in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI).BackgroundPrevious randomized trials have demonstrated that statin pre-treatment reduced major adverse cardiac events (MACEs) in patients with stable angina pectoris and acute coronary syndrome. However, no randomized studies have been carried out with STEMI patients in a primary PCI setting.MethodsA total 171 patients with STEMI were randomized to 80-mg atorvastatin (n = 86) or 10-mg atorvastatin (n = 85) arms for pre-treatment before PCI. All patients were prescribed clopidogrel (600 mg) before PCI. After PCI, both groups were treated with atorvastatin (10 mg). The primary end point was 30-day incidence of MACE including death, nonfatal MI, and target vessel revascularization. Secondary end points included corrected thrombolysis in myocardial infarction frame count, myocardial blush grade, and ST-segment resolution at 90 min after PCI.ResultsMACE occurred in 5 (5.8%) and 9 (10.6%) patients in the 80-mg and 10-mg atorvastatin pre-treatment arms, respectively (p = 0.26). Corrected thrombolysis in myocardial infarction frame count was lower in the 80-mg atorvastatin arm (26.9 +/- 12.3 vs. 34.1 +/- 19.0, p = 0.01). Myocardial blush grade and ST-segment resolution were also higher in the 80-mg atorvastatin arm (2.2 +/- 0.8 vs. 1.9 +/- 0.8, p = 0.02 and 61.8 +/- 26.2 vs. 50.6 +/- 25.8%, p = 0.01).ConclusionsHigh-dose atorvastatin pre-treatment before PCI did not show a significant reduction of MACEs compared with low-dose atorvastatin but did show improved immediate coronary flow after primary PCI. High-dose atorvastatin may produce an optimal result for STEMI patients undergoing PCI by improving microvascular myocardial perfusion.
