Heart imaging to predict sudden cardiac death risk

This research study is examining whether detailed heart imaging can better predict which patients are at risk for sudden cardiac death. Right now, doctors mainly use a simple heart function measurement to decide who needs an implanted defibrillator device (a small machine that prevents dangerous heart rhythms). This study hopes to show that additional detailed pictures of the heart's structure can identify at-risk patients more accurately.

Many patients receive implanted defibrillators based on current guidelines, but most never actually have a life-threatening heart rhythm problem. This study exists to develop better ways of identifying which patients truly need this device, so fewer people receive unnecessary implants while making sure high-risk patients don't get missed.
