Ear-Zap therapy could lift mood in heart attack survivors

This study tests a non-invasive device that gently stimulates a nerve in the ear to see if it can reduce depression symptoms in people who have had a heart attack or related heart problem and a stent placed. About 120 adults will use the device at home for 8 weeks, and their mood will be tracked for another 8 weeks. Half will get the real stimulation, and half will get a fake version, so researchers can see if it truly helps.
