This study investigates potential protective effect of atorvastatin pre-treatment in patient
with stable coronary artery disease undergoing percutaneous coronary intervention (PCI) on
chronic statin therapy. Patients are randomized into two groups: atorvastatin pre-treatment
group (80mg atorvastatin seven days before PCI) and control group (PCI without atorvastatin
pretreatment, chronic statin treatment). Endpoint is myocardial infarction measured by
troponin I and creatine kinase myocardial band.
