NCT05223894

Brief Summary

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.
