Abstract:
Objective To evaluate the feasibility of autologous mononuclear bone marrow cells (BMCs) transplantation in patients with anterior myocardial infarction. Methods Twenty-two patients were enrolled in this prospective, nonrandomized, control study (14 patients in cell transplantation group; 8 in control group). All patients underwent standard percutaneous coronary intervention (PCI) and drug therapy. 14 patients in the cell transplantation group were transplanted with autologous mononuclear (BMCs) via a over-the-wire (OTW) balloon catheter slowly placed into the left anterior descending (LAD) coronary artery during inflation. Results One patient in the cell transplantation group died of acute drug eluting stent thrombosis. The other 13 patients and the 8 patients in the control group had no procedure related complications and ventricular arrhythmia. All patients in both groups underwent 3-month and 6-month follow-up, 6 minutes test, 2D Doppler echocardiogram, single photon emission computed tomography and cardiac magnetic resonance imaging (MRI). After 3 months of follow-up, a significant increase of left ventricular ejection fraction (LVEF) determined by ultrasonic cardiography was found [(50.37?7.31)% vs (40.12?5.52)% before transplantation, P =0.000?1] and was also significantly greater compared with the control group [(50.37?7.31)% vs (44.09?3.50)%, P =0.035]. Conclusion The result indicates that selective intracoronary transplantation of autologous mononuclear BMCs seems to be feasible and may improve the left ventricular systolic function.
