Landmark trial shows Boston Scientific CRT-Ds slow the progression of heart failure in asymptomatic and mildly symptomatic patients
NATICK, Mass., June 23 /PRNewswire-FirstCall/ -- Boston Scientific Corporation (NYSE: BSX) and the
MADIT-CRT, sponsored exclusively by Boston Scientific, demonstrates that early intervention with cardiac resynchronization therapy can slow the progression of heart failure. It is the world's largest randomized NYHA Class I/II CRT-D trial, with more than 1,800 patients enrolled at 110 centers in 14 countries. The trial is being conducted under the leadership of Principal Investigator Arthur J. Moss, M.D., Professor of Medicine at the
"We are very encouraged by these initial positive results, and we are hopeful they will eventually lead to a wider population of heart failure patients being treated with CRT-D therapy," said Fred Colen, President, Boston Scientific CRM. "I would like to congratulate Dr. Moss, the Executive Committee and all the MADIT-CRT investigators on a well designed and well executed clinical trial. Boston Scientific is proud to continue the tradition of supporting advances in indications in the CRM space through trials like MADIT-CRT. More than 80 percent of U.S. patients who receive an ICD or CRT-D were first indicated for this therapy by a clinical trial sponsored by Boston Scientific or its predecessors(3)."
MADIT-CRT is providing insight into the potential of CRT-D therapy to intervene earlier in the natural progression of heart failure. Currently, patients must be in NYHA Class III/IV heart failure to be indicated for CRT-D therapy. However, approximately 70 percent of all heart failure patients in the U.S. fall into Class I or II. Nearly 22 million people worldwide, including approximately 5.5 million Americans, suffer from some form of heart failure.
