Pump failure complicating acute myocardial infarction: the use of the intraaortic balloon pump support in emergency interventional procedures / 中国介入心脏病学杂志

ABSTRACT

Objective To evaluate the effects of intraaortic balloon pump (IABP) support in the emergency interventional procedures on pump failure or cardiogenic shock complicating acute myocardial infarction (AMI). Methods Group A included 21 patients with IABP support during the emergent interventional procedures, and group B included 66 patients without IABP. The two groups were compared for clinical criteria and in-hospital events or complications.Results No significant differences were noted between the two groups witch regard to baseline age, gender, onset of chest pain, timing of intervention, location of AMI, the number of coronary artery diseases, individual infarct-related artery, and TIMI grade before intervention. The degree of pump failure was significantly worse in group A than in group B. In a follow-up period of in-hospital, mortality and revascularization in-hospital were lower in the patients with IABP than in the patients without IABP. Conclusion The combination of early IABP and successful emergency coronary intervention is associated with improved survival in patients with pump failure or cardiogenic shock complicating AMI.
