Summary

This study tested whether a device that gently stimulates a nerve in the ear (vagus nerve) can help control blood pressure during heart stent placement. 480 adults with coronary artery disease and high blood pressure were randomly assigned to receive either real or sham stimulation. Researchers compared blood pressure changes between the two groups during the procedure.
