2. An ST-elevation MI (STEMI) within 2 to 10 days of study enrollment. The STEMI must be documented by ECG with ST-segment elevation >1 mm in at least 2 contiguous precordial leads or in at least 2 adjacent limb leads. If there is a history of a previous AMI prior to the qualifying MI, then there must be a documented EF ≥ 50% by 2D echocardiogram within 12 months of enrollment.
