Intramyocardial bone marrow stem cell transplantation during coronary artery bypass surgery: a meta-analysis.

Experimental and clinical studies have suggested that intramyocardial bone marrow stem cell transplantation combined with coronary artery bypass grafting might improve left ventricular function in the setting of chronic ischemic heart disease. We therefore conducted a systematic review and meta-analysis of available publications regarding the efficacy and safety of intramyocardial bone marrow stem cell transplantation during coronary artery bypass grafting.
