title: Impact of intra-aortic balloon pump on short-term clinical outcomes in ST-elevation myocardial infarction complicated by cardiogenic shock: A "real life" single center experience.
abstract: OBJECTIVE
  To analyze the use and impact of the intra-aortic balloon pump (IABP) upon the 30-day mortality rate and short-term clinical outcome of non-selected patients with ST-elevation acute myocardial infarction (acute STEMI) complicated by cardiogenic shock (CS).
  
  
  METHODS
  A single-center retrospective case-control study was carried out.
  
  
  METHODS
  Coronary Care Unit.
  
  
  METHODS
  Data were collected from 825 consecutive patients with acute STEMI admitted to a Coronary Care Unit from January 2009 to August 2015. Seventy-three patients with CS upon admission subjected to emergency percutaneous coronary intervention (PCI) were finally included in the analysis and were stratified according to IABP use (44 patients receiving IABP).
  
  
  METHODS
  Cardiovascular history, hemodynamic situation upon admission, angiographic and procedural characteristics, and variables derived from admission to the Coronary Care Unit.
  
  
  RESULTS
  Cumulative 30-day mortality was similar in the patients subjected to IABP and in those who received conventional medical therapy only (29.5% and 27.6%, respectively; HR with IABP 1.10, 95% CI 0.38-3.11; p=0.85). Similarly, no significant differences were found in terms of the short-term clinical outcome between the groups: time on mechanical ventilation, days to hemodynamic stabilization, vasoactive drug requirements and stay in the Coronary Care Unit. Poorer renal function (HR 3.9, 95% CI 1.4-10.6; p=0.008), known peripheral artery disease (HR 3.3, 95% CI 1.2-9.1; p=0.019) and a history of diabetes mellitus (HR 3.2, 95% CI 1.2-8.1; p=0.018) were the only variables independently associated to increased 30-day mortality.
  
  
  CONCLUSIONS
  In our "real life" experience, IABP does not modify 30-day mortality or the short-term clinical outcome in patients presenting STEMI complicated with CS and subjected to emergency percutaneous coronary revascularization.
