Study on clinical outcome of PCI for AMI with heart failure or cardiogenic shock

Objective To observe the short and middle-term effects of percutaneous coronary intervention (PCI) on patients with ST-segment elevation acute myocardial infarction(AMI) complicated by heart failure or cardiogenic shock.Methods 90 cases with AMI were recruited,of which 58 cases were treated by PCI and 20 cases were treated by thrombolysis respectively,however,no reperfusion therapy was performed in another 12 cases.Lenth of hospital stay,major adverse cardiac event and left ventricular ejection fraction(LVEF) were compared in PCI and thrombolysis groups.The relationship between patency time of infarcted related artery (IRA),TIMI grade after PCI and prognosis were analysed in PCI group.Results The patency rates of IRA was significantly improved in patients receiving PCI therapy (P 0.01). Compared with thrombolysis group,the LVEF was also higher in PCI group and mortality was much lower during in-hospital and follow-up period.Conclusion Compared with thrombolysis,PCI was a more effective therapy to treat ST-segment elevation AMI companied with heart failure or cardiogenic shock.
