Abstract 【Objective】To evaluate the predictive effect of grade 3 ischemia（G3I）on postoperative ST segment resolution (STR) in patients with acute STsegment elevation myocardial infarction (STEMI) underwent primary percutaneous coronary intervention (pPCI). 【Methods】Two hundred and eightytwo patients with STEMI were selected, According to the degree of STR, they were divided into STR group (n=234) and nonSTR group (n=48), the patients were followed up for 12 months, and the major adverse cardiovascular events within hospital and discharged were recorded. 【Results】82.9% of pPCI postoperative ST segment fell good, those fell bad accounted for 48 (17.1%). The level of serum Nterminal pro brain natriuretic peptide (NTproBNP) B, Troponin I (cTnI),the peak of creatine kinase isoenzyme (CKMB) and the incidence of G3I in the nonSTR group were significantly higher than those in the STR group, and LVEF was lower than that of the STR group. Killip grading difference between the two groups was statistically significant (mean P<0.05). Logistic regression analysis showed that G3I was an independent predictor of nonSTR after pPCI (P=0.018). The average length of hospital stay in patients of the nonSTR group after pPCI was longer (P=0.011), and the incidence of major adverse cardiac events was high (P=0.026).【Conclusion】G3I on initial ECG can predict nonSTR of STEMI patients after pPCI. Patients with nonSTR often have poorer clinical outcomes.
