RESUMO
Objective:To explore the therapeutic effect of intra-aortic balloon counterpulsation (IABP)on acute my-ocardial infarction (AMI)complicated pump failure.Methods:Clinical data of 82 AMI patients complicated pump failure,which received emergency percutaneous coronary intervention (PCI)in our hospital from Jan 2010 to Oct 2013,were retrospectively analyzed.The patients were divided into IABP group (n=42,received PCI with auxiliary IABP)and routine PCI group (n=40,only received routine PCI therapy).Success rate of treatment,mortality,he-modynamic conditions [systolic blood pressure (SBP),diastolic blood pressure (DBP)and heart rate (HR)]stable to PCI time,length of hospital stay and complications were compared between two groups.Results:Compared with routine PCI group after treatment,there were significant rise in blood pressure [SBP: (80.3± 16.2)mmHg vs. (88.4±12.5)mmHg,DBP:(55.4±10.2)mmHg vs.(60.0±10.5)mmHg]and urine volume [(30.2±8.3)ml/h vs.(40.3±9.4)ml/h],and significant reduction in HR [(92.4±26.1)times/min vs.(80.5±18.5)times/min] in IABP group,P 0.05).Conclusion:IABP adjuvant treatment helps to raise success rate of PCI,improve hemodynamic condition and increase urine volume,shorten length of hospital stay in patients with AMI complicated pump failure.
