- W3032620897 abstract "Objective To survey ST-segment resolution in STEMI patients undergoing emergency percutaneous coronary intervention (PCI) and to find the specific clinical features of patients with inadequate ST-segment resolution.Methods A total of 198 patients were divided into two groups according to the ratio of ST-segment resolution:relatively adequate ST-segment resolution group (> 50%) and inadequate STsegment resolution group (< 50%).The clinical features,infarct-related artery and PCI-related evants were evaluated,and major adverse cardiovascular events (MACE including target vessel revascularization,recurrent myocardial infarction,or death) were recorded during hospitalization and follow-up period.Multivariate logistic analysis was used to identify relevant factors influencing ST-segment resolution of STEMI patients after treatment with PCI.The Statistical analyses of data were carried out using SPSS 10.0 software.Results (1) There were 156 patients with relativey adequate ST-segment resolution and 42 patients with inadequate ST-segment resolution.Of them,there were higher percentage of patients aged over 75years in the inadequate ST-segment resolution group than those in the relatively adequate ST-segment resolution group (9 cases,21.4% vs.14 cases,9.0% ; P <0.05).(2) In inadequate ST-segment resolution group,thetotal ischemic time was significant longer [(5.2 ±2.2) h vs.(3.0 ± 1.6) h,P <0.01].The infarctrelated artery (IRA) was more common at left anterior descending coronary artery (LAD) (27 cases,64.3% vs.69 cases,44.2%; P < 0.05) and there were fewer patients with TIM grade 3 of IRA in inadequate ST-segment resolution group after primary PCI than that in relative adequate ST-segment resolution group (32 cases,76.2% vs.140 cases,89.7% ; P < 0.05).There was a lower rate of using GP Ⅱ b/Ⅲ a receptor antagonist and a higher rate of prescribing IABP in inadequate ST-segment resolution group.(3) There is a higher incidence of MACE during hospitalization and follow-up period in patients with inadequate ST-segment resolution.(4) Multivariate logistic analysis indicated that age over 75 years,LAD occlusion,the total ischemic time were related to ST-segment resolution.Conclusions The patients with age over 75 years,LAD occlusion,longer ischemia time,and unemployment GP Ⅱ b/Ⅲ a receptor antagonist before PCI were prone to get inadequate ST-segment resolution and poor prognosis.Age over 75 years,LAD occlusion,and longer ischemic time were independent risk factors of the inadequate ST-segment resolution in STEMI patients after emergency PCI.Key words: ST-segment resolution; Emergency revascularization; ST-segment elevation myocardial infarction ; ECG; ST segment ; Predictive factors ; Emergency interventional therapy ; Clinical characteristics" @default.
