Predicting 30-day heart problems after gastrointestinal surgery using AI versus standard risk scores

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a mixed retrospective–prospective observational effort at Bach Mai Hospital to develop an AI-based multimodal prediction model for major cardiovascular events occurring within 30 days after gastrointestinal surgery. The model will draw on preoperative, intraoperative, and postoperative clinical, laboratory, physiologic, and procedural data from adult patients treated in 2025–2026. Investigators will compare the AI model's predictive performance with traditional scores (RCRI, ACS NSQIP MICA, and ACS NSQIP SRC) using measures such as discrimination, calibration, and clinical usefulness. The primary outcome is major cardiovascular events (cardiovascular death, nonfatal MI, cardiac arrest with return of spontaneous circulation, new stroke, and related events) within 30 days after surgery.
