Abstract
Cell sheet transplantation is emerging as an appealing alternative for ischemic heart disease patients as it potentially can increase stem cell viability and retention. But the outcomes and safety of this treatment are still limited in literature and the result varies widely. We conduct a systematic review to look at the efficacy and safety of this promising transplantation method. A systematic review was performed according to PRISMA guidelines. A comprehensive literature search was undertaken using the PubMed, Scopus, and Embase databases. Articles were thoroughly evaluated and analyzed. Seven publications about cell sheet transplantation for ischemic heart disease patients were included. The primary outcomes measured were left ventricular ejection fraction (LVEF) and New York Heart Association (NYHA) class. Safety measurement was depicted by cardiac-related readmission and deaths. The follow-up time ranged from 3 to 36months for clinical outcomes and 8.5years for safety outcomes. Cell sheet transplantation showed improvement in LVEF and NYHA class in most studies. Cardiac-related readmission and adverse events of cell sheet transplantation range from 0 to 30.4%, all were nonfatal as no cardiac-related death was reported. Patient preoperative status seems can affect the patient's response to cell sheet therapy. Cell sheet transplantation can safely improve LVEF and NYHA class in ischemic heart disease patients, even in very low ejection fraction patients with unsuccessful standard therapy before. Further studies with better patient inclusion, larger population, and long-term follow-up required to confirm these results.
