Abstract

BACKGROUND: The long-term effects of bone marrow-derived cells (BMC) transplantation in patients with acute myocardial infarction (AMI) have not been established. The present meta-analysis of randomized controlled trials with follow-up ≥ 2 years was performed to investigate the long-term effects of BMC therapy in patients after AMI.

METHODS: Specific terms were used to conduct a systematic literature search of MEDLINE, EMBASE, the Cochrane Library and the Cochrane Central Register of Controlled Trials, and the China Biological Medicine Disk database from their inception to March 2012. A standardized protocol was used to extract information, and random effect model was used to analyze all data except major adverse events.

RESULTS: Five trials comprising 510 patients were included. Compared with controls, BMC therapy significantly improved left ventricular ejection fraction (LVEF) (4.18%, 95%CI: 2.02% to 6.35%, P = 0.0002), while mildly but not significantly reduced left ventricular end-systolic volume (-4.47 ml, 95%CI: -10.92 to 1.99, P = 0.17) and left ventricular end-diastolic volume (-2.29 ml, 95%CI: -9.96 to 5.39, P = 0.56). Subgroup analysis revealed that significant improvement of LVEF induced by BMC therapy could be observed in patients with baseline LVEF ≤ 42%, but disappeared in those with baseline LVEF > 42%. There were trends in favor of BMC therapy for most major clinical adverse events, though most differences were not significant.

CONCLUSIONS: Intracoronary BMC infusion in patients with AMI seems to be safe and may further improve LVEF on top of standard therapy; especially the beneficial effects could last for long term. The findings need to be validated in the future.
