Abstract
Abstract Background Cell therapy using adipose-derived mesenchymal stem cells (ADSCs) shows great potential as a treatment for cardiovascular diseases. Objective We conducted a systematic review to describe the safety and efficacy of ADSCs in ischemic heart disease. Methods We searched PubMed/MEDLINE, EMBASE, Web of Science, CENTRAL, and LILACS (from inception to March 2024) for clinical studies involving ADSCs in patients with ischemic heart disease. We excluded studies involving patients with other types of heart disease, studies using mesenchymal stem cells derived from other tissues, as well as ongoing studies. Two independent reviewers screened the retrieved citations, extracted relevant data, and assessed the risk of bias in the included trials, using the Cochrane Collaboration criteria modified by McMaster University and Methodological Index for Non-Randomized Studies (MINORS). We used a narrative synthesis to present the results. Results Ten studies (comprising 29 publications) met our inclusion criteria, including 8 randomized controlled trials and 2 uncontrolled trials. No severe adverse events associated with ADSC therapy were reported. While most efficacy endpoints did not reach statistical significance, there were reports of improved ischemic area, functional capacity, symptoms, and contractility in patients treated with ADSCs. Conclusions The findings from our review suggest that ADSC therapy is generally safe for patients with ischemic heart disease. However, further investigation is warranted to confirm its efficacy, particularly with larger clinical trials and in specific conditions where improvements in microcirculation may have a notable impact on clinical outcomes.
