Impella® heart pumps
For high-risk patients with reduced cardiac function, hemodynamic instability increases the likelihood of serious complications.1,2 Early, timely intervention with Impella, a minimally invasive assist device indicated for high-risk percutaneous coronary intervention and cardiogenic shock in adult and pediatric (weighing ≥30 kg) patients, can lead to ventricular recovery and improved outcomes.3,4 Impella has the unique ability to increase the systemic blood flow,5-8 supporting end-organs and myocardial recovery.5-9

DanGer Shock RCT
New long-term data from the DanGer Shock RCT, published in the New England Journal of Medicine, validates the durability of original findings and confirms the survival benefit of Impella CP® heart pump increases year-over-year.11

PROTECT II RCT
PROTECT II was a landmark prospective, multicenter, randomized, controlled trial of hemodynamic support with Impella 2.5® versus intra-aortic balloon pump (IABP) in patients undergoing nonemergent high-risk percutaneous coronary intervention (PCI).

PROTECT III RCT
PROTECT III was a prospective, single-arm, FDA post-approval study for the post-marketing approval (PMA) of Impella 2.5® and Impella CP® that demonstrated a reduction in the primary endpoint of death, stroke, myocardial infarction and repeat procedures at 90 days with Impella-supported Protected PCI, compared to PROTECT II.

NCSI Study
National Cardiogenic Shock Initiative (NCSI) Study was an independent, physician-led, national, multicenter initiative aimed at improving mortality in patients with AMI cardiogenic shock (AMICS).12

RESTORE EF
RESTORE EF was designed to validate contemporary best practices in high-risk PCI, including complete revascularization in a single setting, use of atherectomy and large-bore access techniques.

Patients10
Experienced improved ejection fraction10 or NYHA heart failure class10 after a Protected PCI procedure with an Impella heart pump.
16.3%
Absolute mortality reduction11
At up to 10 years, routine use of Impella CP in patients with STEMI complicated by cardiogenic shock leads to an absolute mortality reduction.11
~80%
Survival improvement12,13,14
Impella 5.5 as first line improves survival to nearly 80%, stabilizing patients for optimal long-term recovery and treatment strategies.12,13,14
71%
Survival to discharge15
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).15

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.16
