Peri-procedural ST segment resolution during Primary Percutaneous Coronary Intervention (PPCI) for acute myocardial infarction: predictors and clinical consequences

Good peri-procedural ST resolution was seen in less than half of STEMI patients undergoing PPCI. There were important clinical consequences of good ST resolution. Identification of suboptimal peri-procedural ST resolution could help identify patients who may benefit from new treatments aimed at protecting the microcirculation, whilst the patients are still in the angiography laboratory.
