Summary

This study looks at 421 people who are getting a heart device (ICD) to see if muscle health can help predict sudden cardiac death. Researchers will use AI to combine muscle scans, blood tests, and other data to build a risk prediction tool. No new treatments are tested—the goal is to better understand and forecast dangerous heart events.
