Abiomed Inc. (NASDAQ: ABMD), a leading provider of breakthrough heart support technologies, today announced new clinical data from Academic Medical Center’s (AMC) three-year follow-up results from patients in the Impella 2.5 arm of the MACH II trial, revealing improved left ventricular function, cardiac output and quality of life.
The MACH II trial, evaluating safety and feasibility in STEMI, included 20 patients; ten patients were treated with three days of Impella 2.5 support; ten control patients were treated with routine standard of care. The initial four-month results, which demonstrated significant recovery of left ventricular function in Impella 2.5 patients, were published in the Journal of American College of Cardiology in 2008.
The three-year follow-up results from MACH II were presented by Jose PS Henriques, M.D., Ph.D., Academic Medical Center, University of Amsterdam, at the Abiomed customer evening symposium at TCT 2009. The results measured the three-year follow-up of 20 large anterior STEMI patients in the MACH II trial and demonstrated significant overall improvements in cardiac function as well as quality of life in the ten patients that received Impella 2.5 within the trial.
All patients were measured in an IRB-approved protocol that calculated echo results, exercise testing and quality of life, and showed the following results from core laboratory analysis and strict processes:
