Patching up the heart: Electroconductive cardiac repair.

Cardiac patches matched to myocardial electroconductivity reestablish electrical conduction after injury and induce epicardial endothelial differentiation to support repair.

• Why it matters: Myocardial infarction disrupts both heart conduction and the capacity for surface repair, limiting the effectiveness of implanted patch therapies.
• What they did: Xie et al. tested cardiac patches engineered to match myocardial electroconductivity, assessing whether they restore conduction and drive epicardial cells toward endothelial differentiation.
• The result: The electroconductivity-matched patches both restore conduction and promote heart repair via endothelial differentiation, supporting a design principle for future cardiac patch treatments.
