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.
The 16 patients received different amounts of bone marrow stem cells — 5 million, 10 million and 15 million cells. The 15 patients in the control group received standard medication only. All the patients were followed for up to five years.
After three to six months, patients who received higher doses of bone marrow stem cells showed greater improvement in blood flow within the heart than patients who received lower doses and those in the control group, the researchers said.
