Cardiogenic shock caused by left ventricular failure is associated with high mortality in patients with acute myocardial infarction (AMI). An LVAD may help to bridge patients to recovery from left ventricular failure. In a prospective, randomized study, 26 patients with cardiogenic shock were studied. The primary end point was the change of the cardiac index (CI) from baseline to 30 min after implantation. Secondary end points included lactic acidosis, hemolysis and mortality after 30 days. The CI after 30 min of support was significantly increased in patients with the Impella LP 2.5 compared with patients with IABP. Overall 30-day mortality was 46% in both groups. In patients presenting with cardiogenic shock caused by AMI, the use of the Impella LP 2.5 is feasible and safe, and provides superior hemodynamic support compared with standard treatment using an intra-aortic balloon pump.
