Four anterior STEMIs: acute and reperfused vs. won't reperfuse, subacute and reperfused vs. not reperfused

The patient continued to have ischemia after PCI, and in fact had an episode of polymorphic VT shortly after while in the ICU. Determinants and prognostic implications of persistent ST-segment elevation after primary angioplasty for acute myocardial infarction: importance of microvascular reperfusion injury on clinical outcome.

A dialysis patient with nonspecific symptoms and pseudonormalization of ST segments

Dr. Smith's ECG Blog

Normally, concavity in ST segments suggests absence of anterior ischemia (though concavity by itself is not reassuring - see this study ). The lesion was intervened on with balloon angioplasty and had subsequent TIMI 3 flow. In there ECG evidence of possible ongoing ischemia? (ie, There was initially TIMI 0 flow.
