Timing of ischemic onset estimated from the electrocardiogram is better than historical timing for predicting outcome after reperfusion therapy for acute anterior myocardial infarction: A DANish trial in Acute Myocardial Infarction 2 (DANAMI-2) substudy

The ECG method of timing was superior to historical timing in predicting myocardial salvage and prognosis after reperfusion therapy. This study suggests that ECG estimated duration of ischemia might provide a better and objective means to select acute reperfusion therapy rather than the subjective patient history, which could preclude proper reperfusion in some patients with salvageable myocardium.
