• To evaluate the prognostic value of ST resolution (STR) measured in a single ECG lead obtained early after primary PCI in patients with ST-elevation myocardial infarction (STEMI). In this retrospective study, STR, MACE and factors contributed to STR were analyzed in 964 patients underwent primary PCI post STEMI. The ECGs analysis was made by technicians blinded to the clinical data. MACE was compared between the STR (n = 662) and the non-STR (n = 302) groups. Factors associated with non-STR were analyzed by logistic regression method. Although TIMI grade III flow was achieved after PCI, non-STR was shown in nearly 1/3 patients and these patients were older, dominant with anterior myocardial infarction, cardiac dysfunction, diabetes and was associated with a higher MACE ratio (25.5% vs. 4.4%, P < 0.001). Cox regression showed that non-STR was one of the independent predictors of in-hospital MACE (RR = 3.33, P < 0.001). Logistic regression showed that anterior myocardial infarction, the pain to balloon time, ca
