• In the heart, SUR2 couples with a potassium channel to form an adenosine triphosphate–sensitive complex that responds to the energy state of the cell.
• The authors deleted SUR2 in adult cardiomyocytes and found a shift of the heart toward glycolytic metabolism, which is protective under cardiac stress.
• SUR2 was found to complex with glucose transporter type 4, the major glucose transporter.
• Drugs that antagonize the SUR2 receptor may be cardioprotective and useful for managing heart failure.
