AI-assisted Subtyping-directed Precision Treatment in Acute Aortic Dissection

January 28, 2026 updated by: Hong Liu, Nanjing Medical University

AI-assisted Immunoinflammatory Subtyping-Directed Precision Treatment in Acute Aortic Dissection: A Multicenter RCT-based Exploration

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

No

Description

Inclusion Criteria:

  1. Confirmed diagnosis of acute aortic dissection by contrast-enhanced Computed Tomography Angiography (CTA) or Magnetic Resonance Angiography (MRA);
  2. Planned emergency surgical treatment (including open surgery and endovascular repair);
  3. Aged 18-80 years old, regardless of gender;
  4. Time from onset to hospital admission ≤ 72 hours;
  5. Signed informed consent form by the patient or their authorized agent, with willingness to cooperate with the follow-up of the study.

Exclusion Criteria:

  1. 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);
  2. Long-term use of immunosuppressants or glucocorticoids before surgery (continuous use for ≥ 2 weeks);

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

Experimental: Subtyping-based precision therapy

  • Balanced type (HIS1): No anti-inflammatory intervention required;

    • Inflammation-excessive type (HIS2): Anti-inflammatory intervention with ulinastatin; ③ Immunosuppressive type (HIS3): Immunomodulation with thymalfasin; ④ Mixed reaction type (HIS4): Combined treatment with ulinastatin and thymalfasin.
Drug: Ulinastatin and Thymalfasin
AI-assisted Immunoinflammatory Subtyping-guided Target-matching Individualized Anti-inflammatory Strategy
Active Comparator: Conventional Empirical Strategy
treatment of physician's choice alone
Drug: Ulinastatin
Conventional empirical regimens will be formulated based on patients' clinical symptoms and routine inflammatory indicators (white blood cell count, C-reactive protein, procalcitonin) without uniform target-matching standards, with reference to clinical diagnosis and treatment guidelines: if obvious inflammatory responses are present (e.g., fever, significant elevation of C-reactive protein), non-steroidal anti-inflammatory drugs or low-dose glucocorticoids will be administered; if complicated with infection, combined antibiotic therapy will be given; for patients with normal or slightly elevated inflammatory indicators, anti-inflammatory drugs may be temporarily withheld, and close monitoring will be performed instead. The regimen will be adjusted according to changes in routine inflammatory indicators after surgery until the patient is discharged.
