The open infarct-related artery theory: a critical view.

Early reopening of the infarct-related artery salvages myocardium and, consequently, preserves left ventricular function, which results in an improved survival rate (the early open infarct-related artery theory). Nevertheless, late patency of the infarct-related artery is also important, because it prevents ventricular remodeling (the late-open infarct-related theory). A comprehensive view of the importance of both conditions is presented.
