title: [Influencial factors for in-hospital patients with ST segment elevation myocardial infarction after emergency percutaneous coronary intervention].
abstract: To analyze the clinical outcomes of emergency percutaneous intervention in acute myocardial infarction (AMI) during hospital, and to find the relevant risk factors for the prognosis and cardiac events.   Methods: We retrospective analyzed the patient with acute ST segment elevation myocardial infarction, who was successfully performed emergency percutaneous coronary intervention (PCI) in the Cardiac Cath Lab of the Second Xiangya Hospital from January 2010 to December 2014. According to situation for cardiovascular events, patients were divided into 2 groups. The clinical factors were compared between the 2 groups.  Results: The incidence of adverse event was 22% (67/304). By using t test and χ2 analysis, we found that Cr, NT-proBNP, HCT, WBC, age>75, Killip grade≥2, TIMI flow after PCI≤2, arrhythmia, multi-vessel lesion, ST-segment resolution≥50%, long D2B time are statistically different between the 2 groups. Logistic analysis revealed that HCT, NT-proBNP, Killip grade≥2, TIMI flow after PCI≤2, ST-segment resolution≥50%, long D2B time were important predictors for cardiac events in-hospital.  Conclusion: HCT, NT-proBNP, Killip grade≥2, TIMI flow after PCI≤2, ST-segment resolution≥50%, long D2B time are important predictors for cardiac events in-hospital. The prognosis for AMI patient after emergency PCI could be improved and the incidence of cardiac event in hospital could be reduced if the high risk factors can be properly handled.
