Abstract
Blocking 
-adrenergic receptors is a standard treatment for heart failure, but it limits the normal ability to modulate cardiac function. Targeting therapy further downstream by blocking activation of calcium-calmodulin–dependent protein kinase could provide an alternative (pages 409–407).
In this issue, Zhang et al.1 investigate a new approach to treat heart failure—inhibition of calcium-calmodulin–dependent protein kinase II (CaMKII). This represents a potentially more specific target than the current standard therapy for heart failure, -adrenergic receptor blockade.
