Infarct size and myocardial salvage after primary angioplasty in patients presenting with symptoms for <12 h vs. 12-72 h

Abstract

FIS is larger in late presenters (>12 h) than early presenters after primary angioplasty for STEMI. However, substantial myocardial salvage can be obtained beyond the 12 h limit, even when the infarct-related artery is totally occluded.
