[Observation of short- and mid-term clinical outcome of percutaneous coronary intervention for acute myocardial infarction with heart failure or cardiogenic shock].
OBJECTIVE
To observe the short- and mid-term effects of percutaneous coronary intervention (PCI) in patients with ST-segment elevation acute myocardial infarction (AMI) complicated by heart failure and/or cardiogenic shock .


METHODS
Altogether 90 patients with AMI were recruited, of whom 58 were treated by PCI, 20 by thrombolytic therapy, and the other received general treatment without reperfusion therapy. The length of hospital stay, major adverse cardiac events (MACE) and left ventricular ejection fraction (LVEF) were compared between PCI and thrombolysis groups. The relationship between the patency time of the infarct-related artery (IRA), thrombolysis in myocardial infarction (TIMI) grade after PCI and prognosis were analyzed in PCI group.


RESULTS
The patency rate of IRA was significantly improved in patients receiving PCI therapy in comparison by those with thrombolytic therapy (98.3% vs 65.0%, P<0.01), and the LVEF was also higher in PCI group with lower mortality (6.9% vs 25.0%, P<0.05) during in-hospital and follow-up period.


CONCLUSIONS
PCI can be a more effective therapy than thrombolytic therapy in the treatment of ST-segment elevation AMI accompanied with heart failure and/or cardiogenic shock.
