This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is testing a device called the Parasym Device, which uses low-level electrical stimulation on the tragus (the small cartilage flap in your ear) to see if it can help people who have had a severe heart attack called ST-elevation myocardial infarction (STEMI). Researchers want to know if this ear stimulation can improve heart rhythm patterns, reduce inflammation, and prevent serious complications after a heart attack. Half of the participants will receive active stimulation, and half will receive a device that looks the same but doesn't actually stimulate.
After a severe heart attack, the heart's nervous system can become imbalanced, leading to dangerous heart rhythms, blood clots, and other life-threatening complications. Early research suggests that gentle stimulation of a nerve in the ear might help restore the heart's natural balance and reduce these risks.

If you enroll, you will be randomly assigned to either the active stimulation group or the sham (control) group. Before your emergency heart procedure, you'll have blood tests and a heart rhythm measurement, then receive 60 minutes of either active or sham ear stimulation using the Parasym Device. After your emergency procedure (called primary percutaneous coronary intervention or PPCI), you'll have repeat blood tests and heart rhythm measurements. The entire study involves tests and measurements before and after your heart procedure on the same day.
