When treating ST-elevation myocardial infarction (STEMI) with primary percutaneous coronary intervention (PPCI) a successful restoration of coronary epicardial blood flow does not guarantee sufficient microvascular perfusion or optimal outcome. Thus, one-third of patients achieving thrombolysis in myocardial infarction flow grade 3 have compromised microvascular perfusion, which may have prognostic implications.¹ Such patients nay be identified by single photon emission computed tomography, positron emission tomography or stress Echo. These methods, however, cannot help us in triaging per-interventional or early post-interventional treatment because they are not available 24-hourly, require skilled personnel for the interpretation and the results are not available until a time at which irreversible myocardial damage has occurred. ECG analysis, even though introduced more than 100 years ago,² may provide valuable prognostic information even in the era of PPCI. It is well established that early and complete resolution of ST-segment elevation is a powerful predictor of infarct-related artery patency, preserved . . . [Full text of this article]
