Heart failure has a high morbidity and mortality because the heart is one of the least regenerative organs in the human body. Drug treatments for heart failure manage symptoms but do not restore lost myocytes. Cellular replacement therapy is a potential approach to repair damaged myocardial tissue, restore cardiac function, which has become a new strategy for the treatment of heart failure. The purpose of this study is to assess the safety and efficacy of intramyocardial delivery of cardiomyocytes at the time of coronary artery bypass grafting in patients with chronic heart failure.
Patients with heart failure will be treated with allogenic human pluripotent stem cell-derived cardiomyocytes ( hPSC-CM ) from healthy donors. The cells will be injected directly into the myocardium at time of coronary artery bypass grafting. Patients will be assessed at 1, 3, 6 and 12 months after cell transplantation for safety and efficacy.

It classifies patients in one of four categories based on their limitations during physical activity; Class I - No symptoms and no limitation in ordinary physical activity, e.g. shortness of breath when walking, climbing stairs etc. Class II - Mild symptoms (mild shortness of breath and/or angina) and slight limitation during ordinary activity. Class III - Marked limitation in activity due to symptoms, even during less-than-ordinary activity, e.g. walking short distances (20-100 m).Comfortable only at rest. Class IV - Severe limitations. Experiences symptoms even while at rest. Mostly bedbound patients. | Baseline, 1, 3, 6 and 12 Months Post-operation |
