A random-forest machine learning model leveraging cardiac MRI and patient health history improves prediction of major adverse cardiovascular events.
Key Details
- 1Study involved 2,159 patients referred for adenosine perfusion cardiac MRI.
- 2Random-forest model used both MRI/demographics and 10 years of historical health registry data.
- 3Primary outcome was major adverse cardiovascular events—including death, MI, unstable angina, or intervention (MACE occurred in 9.1% of patients).
- 4Random-forest model with historical data achieved a C-index of 0.81, outperforming Cox regression's 0.77 (p < 0.001).
- 5Presenting institution: Lund University, Sweden; data presented at 2026 ISMRM meeting.
