A Canadian first
Before the IMPACT-CABG trial, previous studies in other countries had also evaluated the safety and feasibility of injecting different stem cells in the hearts of patients with cardiac dysfunction. This is a first study in Canada evaluating intramyocardial injection of stem cells. "Also, no research team in the country had implemented such a complete treatment process, going from harvesting stem cells in the patient, treating them, and injecting them directly into the myocardium," states Dr. Nicolas Noiseux, cardiac surgeon at the CHUM and principal investigator in the study. "Moreover, the methods used to evaluate the recovery of heart function make use of cutting-edge imaging techniques," reports Dr. Samer Mansour, cardiologist at the CHUM, principal co-investigator.
To prepare for the intervention, cells from the bone marrow harvested at the CHUM are transferred to the cell therapy laboratory of the MRH to isolate the most immature stem cells, which will be injected directly into the patient's heart. "MRH has developed a unique expertise in cellular therapy. This expertise serves cardiology in those specific cases and we hope to develop other applications to regenerate the cornea, cartilage and other tissues and organs," adds Dr. Denis Claude Roy, haematologist, Director of research and Director, Cell therapy Laboratory at MRH, and also a principal co-investigator.
