The purpose of this study is to determine whether intracoronary transfer of autologous bone marrow cells can induce angiogenesis, subsequently improving regional myocardial perfusion, and finally resulting in improved systolic and diastolic left ventricular function in patients with myocardial infarction.
50 patients with stable left ventricle function will - with six months interval - receive two treatments with bone marrow transplantation intracoronary in vessels supplying dysfunctional myocardial territories and Coronary Artery Bypass Graft (CABG).

This research study is being performed to find out more information about the safety and efficacy of autologous bone marrow stem cells transplantation. In patients with myocardial infarction, the heart muscle does not pump well. Over a period of years, this continues to get worse until the patient dies of heart failure. The researchers are trying to find out if the transplantation of these stem cell can make a change in the functioning of these areas of the heart muscle.
Patients between 18 and 70 years of age who received autologous bone marrow stem cell transplant at the Fuwai cardiovascular hospital may be eligible for this study. Candidates must have had their first transplant at least 3 years before entering the current study.
These patients receive autologous bone marrow cells transplantation intracoronary undergoing Coronary Artery Bypass Graft. The objective evaluations will be performed at baseline and during 6 months follow-up.
Heart function tests may include the following:
- Electrocardiogram (EKG) evaluates the electrical activity of the heart. Electrodes placed on the chest transmit information from the heart to a machine.
- Echocardiogram (Echo) is an ultrasound test that uses sound waves to create an image of the heart and examine the function of the heart chambers and valves.
- Gated acquisition scan is a nuclear medicine test that uses a small amount of radioactive chemical injected into a vein. A special scanner creates an image of the heart for examining the beating motion of the muscle.
- MRI evaluates function of the heart chambers the beating motion of the muscle.
