However, several gaps in knowledge exist regarding optimal patient selection, futility criteria, timing, weaning and escalation strategy, and until data from adequately sized randomized trials are available, immediate individual evaluation for mechanical circulatory support by a shock team is warranted when a patient is diagnosed with AMICS.ĪMICS is also a spectrum of severity of disease that recently has been categorized into five classes by the Society for Cardiovascular Angiography and Interventions (SCAI). Registry data suggest that pre-PCI Impella may be advantageous to post-PCI placement. It is likely that the SCAI C patient with predominantly left ventricular failure and without prolonged cardiac arrest is the best candidate for these devices. Consequently, the use of axial flow pumps, especially the Impella devices, is increasing. Axial flow pumps offer hemodynamic support without increasing myocardial oxygen consumption. In this situation, a treatment that unloads the myocardium and restores CO without increasing the myocardial oxygen demand is theoretically appealing. Acute myocardial infarction complicated by cardiogenic shock (AMICS), is characterized by critically low cardiac output and decreased myocardial contractility.
