Summary

This trial tests whether an AI-driven health management program can reduce the chance of a first ischemic stroke in adults at high risk. Participants in Beijing communities will be randomly assigned to either AI-supported care or usual community health services. The AI program uses digital tools, wearable data, and personalized guidance to help manage risk factors. Over 36 months, researchers will compare stroke rates between the two groups to see if the AI approach makes a difference.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: AI-driven dynamic health management platform (AI-ExpoStroke) with digital tools, wearables, and personalized guidance
What this could lead to: If successful, this could establish AI-supported health management as an effective strategy to prevent first strokes in high-risk populations, potentially reducing stroke-related disability and death.
What could go wrong: The trial is large but relies on community-based implementation, which may vary in adherence. The AI model's predictive accuracy and the intervention's real-world effectiveness are unproven, and results may not generalize beyond Beijing.
