Study to Examine the Safety and Effectiveness of Implanted Skeletal Muscle Cells (Cells Removed From the Thigh Muscle) Into Scarred Areas of Heart Muscle After Heart Attack.

Inclusion Criteria: * Patients recommended for coronary bypass surgery (preferably with cardiopulmonary support) * Ejection fraction ≥15% and ≤35% * Left ventricular myocardial infarction (MI - heart attack) ≥4 weeks prior to screening Exclusion Criteria: * Need for a rapid surgical coronary revascularization * Need for any other related cardiosurgical measure during coronary surgery (e.g. mitral valve repair or valve replacement) * Patients with a left ventricular aneurysm who is a candidate for left ventricular aneurysmectomy or left ventricular reduction surgery; patient receiving left or biventricular (BiV) pacing therapy for heart failure (unless the patient has stabilized after 6 or more months of this therapy) * Cardiomyopathy presumed to be of non-ischemic origin
