Title: A Clinical Evaluation of Everolimus Eluting Coronary Stents in the Treatment of Patients With ST-segment Elevation Myocardial Infarction.EXAMINATION Study
Brief Summary: This study is a prospective, randomized controlled, single blind, two-arm, multi center clinical evaluation. A total of 1500 patients will be enrolled in the study.

Patient randomization will be to one of the two treatment arms: Everolimus arm or Non drug eluting stent arm. The objective of this study is to assess the safety and performance of the Everolimus Eluting Coronary Stent System versus a modified cobalt chromium balloon expandable stent in the setting of primary percutaneous coronary intervention for treatment of patients presenting with ST-segment elevation myocardial infarction.
