Effort to Regenerate Heart Tissue Apparently Fails

Injecting a patient's own progenitor bone marrow cells into coronary tissue a few days after a heart attack didn't improve function or reduce damage, according to a study reported today in a late-breaking clinical trials session at the American Heart Association's Scientific Sessions 2005.


The findings contrast with recent reports of success from other research groups in this hotly contested field.

Some previous smaller, randomized studies have shown modest improvement of left ventricular function after intracoronary injections of autologous (the patient's own) bone marrow cells (BMC).
