AI-assisted Subtyping-directed Precision Treatment in Acute Aortic Dissection
China300 participantsStarted 2027-12-31
Plain-language summary
Aortic dissection has acute onset and high mortality, with immunoinflammatory response driving lesion progression. Current perioperative anti-inflammatory therapies are mostly empirical and poorly targeted, and AI-assisted typing lacks a complete clinical translation pathway. This study integrates multi-dimensional data to construct an AI immunoinflammatory subtyping system, enabling rapid subtyping and establishing a "subtyping-target-treatment" closed loop for emergency needs. Using a prospective multicenter RCT, 300 patients are randomly divided into two groups: the experimental group receives subtyping-based precision therapy, while the control group uses empirical strategies (treatment of physician's choice). It observes 7-day postoperative SOFA score, SIRS and other prognostic indicators to provide evidence-based support for precision treatment.

Exclusion criteria
✕. Complicated with underlying diseases that affect immunoinflammatory status, such as severe infections (e.g., sepsis, infective endocarditis), autoimmune diseases, malignant tumors, chronic liver diseases, and chronic kidney diseases (uremic stage);

What they're measuring
1
Sequential Organ Failure Assessment (SOFA) score. The SOFA score evaluates 6 organ systems, ranging from 0, no dysfunction, to 4, failure, and the total score ranges from 0, normal, to 24, most severe form of multiorgan failure.
