RESUMO

OBJECTIVE: myocardial infarction (MI) remains the leading cause of death worldwide. Cell-based therapies have become potential therapeutic approaches, attempting to recover the contractility of necrotic cardiomyocytes. In the present study, we aimed to systematically evaluate experimental studies on the use of tissue-engineered amniotic membrane (hAMC) in MI treatment. METHODS: a systematic review of literature published in PubMed, Embase and CENTRAL databases was conducted, until March 31, 2020, for experimental studies reporting on hAMC cell-therapy performed on LV function, MI size, paracrine effects, angiogenesis, and cell differentiation. Two reviewers selected the articles that met the inclusion criteria and disagreements were solved through a consensus. RESULTS: a total of 11 studies were included for data extraction. For the acute scenario, therapeutic use of hAMC after MI was capable of improving LV function in rats, mainly due to its paracrine effects (anti-apoptotic and anti-inflammatory) and associated with cardiomyocyte differentiation, MI size reduction and neo-angiogenesis. CONCLUSION: tissue engineered hAMC following MI provided clinically relevant benefits on cardiac function and ventricular remodeling.
