Incidence and Significance of Spontaneous ST Segment Re-elevation After Reperfused Anterior Acute Myocardial Infarction

been associated with the extent of myocardial damage, re-infarction, left ventricular (LV) remodeling, and mortality.1–5 Regression of ST segment elevation has been used in several studies to assess the quality of reperfusion.6–9 T he electrocardiogram (ECG) is the first-line diagnostic tool in ST elevation myocardial infarction (STEMI). The ECG is a simple and easily reproducible test, with a non-ambiguous diagnostic ability. ST segment resolution is commonly used as a marker of successful reperfusion. It is an independent prognostic parameter of subsequent adverse events in STEMI patients. In many studies, the absence of ST segment resolution has Editorial p 1249
