A new noninvasive method for analyzing routine heart scans can identify dangerous inflammation in patients at risk for cardiac disease.

A new study in dogs reveals two genes responsible for controlling heartbeat rhythm and re-coordinating the action of the heart’s right and left ventricles. These genes may be part of the molecular pathway affected by pacemakers, researchers report in the 14 September issue of the journal Science Translational Medicine.

Using gene therapy or drugs to activate these genes in heart failure patients may help people who cannot use a pacemaker—or possibly replace pacemakers altogether, the study authors propose.
