Key result
Stem cell therapy for cardiovascular diseases carries a potential proarrhythmic risk due to mechanisms like immature electrical phenotypes, poor cell-cell coupling, and cardiac nerve sprouting.

What are the potential proarrhythmic risks and mechanisms associated with stem cell therapy for cardiovascular diseases?
While stem cell therapy shows promise for myocardial injuries, its potential proarrhythmic risk remains a major concern requiring further investigation.
Requires arrhythmia vigilance in stem cell trials; leaves open net clinical benefit pending prospective data.
Stem cell therapy is an emerging therapeutic approach for the treatment of cardiovascular diseases. Experimental studies have demonstrated that different types of stem cells, including bone marrow-derived cells, mesenchymal stem cells, skeletal myoblasts, and cardiac progenitor cells and embryonic stem cells, can improve cardiac function after myocardial injuries. Nevertheless, the potential proarrhythmic risk after stem cell transplantation remains a major concern. Several mechanisms, including the immaturity of electrical phenotypes of the transplanted cardiomyocytes, poor cell-cell coupling and cardiac nerve sprouting, may contribute to arrhythmogenic risk after stem cell transplantation. This review summarizes the potential theoretical arrhythmogenic mechanisms associated with different types of stem cells for the treatment of cardiovascular diseases. Nevertheless, current experimental and clinical data on the proarrhythmic risk for different types of stem cell transplantation are limited, and await further experimental and clinical investigation.

Liu et al. (2011) conducted a review in Cardiovascular diseases. Stem cell therapy was evaluated on Proarrhythmic risk. Stem cell therapy for cardiovascular diseases carries a potential proarrhythmic risk due to mechanisms like immature electrical phenotypes, poor cell-cell coupling, and cardiac nerve sprouting.
