Application of intraaortic balloon counterpulsation during primary percutaneous coronary intervention in patients with cardiogenic shock complicating with acute myocardial infarction / 中华急诊医学杂志

ABSTRACT

Objective To investigate the safety,efficacy and effects of emergent percutaneous coronary intervention (PCI) in patients from Second Affiliated Hospital,Medical College,Zhejiang University with cardiogenic shock (CS) complicating acute myocardial infarction (AMI).Method Twenty-seven patients with CS complicating with AMI were treated by PCI with intraaortic balloon counterpulsation (IABP) support.The change of hemodynamics before and after IABP and PCI,the characteristics of PCI,the mortality during hospitalization, the major adverse cardiac events (MACE) and left ventricular ejection fraction at 30-day follow-up were observed.Results The hemodynamics were significantly improved after IABP.No patients died during PCI.Two patients died after PCI and the total mortality was 7.4% in hospital.During the period of 30-day follow-up, one patient died of heart failure.The left ventricular ejection fraction greatly improved at 30 days after PCI. Conclusions The data suggested that the use of IABP during PCI in patients with CS complicating AMI was safe, decreased mortality and improved prognosis.
