ACC/AHA Upgrades mAFP to Class 2a and Downgrades IABP and VA-ECMO to Class 3
The new Acute Coronary Syndrome (ACS) guidelines downgrade intra-aortic balloon pump (IABP) and venoarterial extracorporeal membrane oxygenation (VA-ECMO) to Class 3 due to no shown benefit, while microaxial intravascular flow pumps (mAFP), Impella®, is now Class 2a in patients with STEMI and severe or refractory cardiogenic shock.2
Final Results from the National Cardiogenic Shock Initiative (NCSI) Study Report Demonstrate Benefit of Early Impella Cardiac Unloading3
The final results of the physician-led NCSI Study demonstrate a 71% survival to discharge with greater than 90% native heart recovery when best practices are used, including placement of an Impella heart pump prior to revascularization (PCI).3

Native heart recovery at discharge3
NCSI Study is an independent, physician-led, national, multicenter initiative aimed at improving mortality in patients with AMI cardiogenic shock (AMICS).3 Based on the consistent finding of good survival outcomes with early hemodynamic support with Impella therapy from the IQ database and cVAD study, a best practices algorithm for the treatment of patients with AMICS was established. The NCSI Study algorithm includes identifying shock early, use of Impella therapy before PCI, reducing the use of inotropes and the use of invasive hemodynamic monitoring to aid in escalation and weaning.
