Patient's own stem cells might treat heart attack

Treating a heart attack with the patients' own bone marrow stem cells boosts blood flow within the heart and may help reduce long-term complications, a new U.S. study finds. The study included 31 patients who underwent angioplasty and stent placement after a heart attack. Within one week of the attacks, 16 of the patients received infusions of their own bone marrow cells into the coronary artery in which a blockage had caused the event. - Business Week
