AI reads heart traces to find silent liver danger
NCT ID NCT05782283
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested whether an artificial intelligence (AI) tool, called ACE 2.0, can detect undiagnosed liver cirrhosis by analyzing a routine electrocardiogram (ECG). Researchers at Mayo Clinic enrolled 279 primary care clinicians and their adult patients. The AI flagged ECGs that might indicate advanced liver disease, and doctors were alerted. The goal was to see if this approach leads to more early diagnoses compared to usual care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- AI-powered ECG tool (ACE 2.0)
- What this could lead to
- If it works, this could give doctors a simple, cheap way to catch serious liver disease early, before it causes major damage.
- What could go wrong
- This was a small, early study (279 people) and only looked at detection, not treatment. The AI might miss cases or cause unnecessary worry.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Criteria: Inclusion Criteria: * Primary care clinicians (physicians, nurse practitioners, and physician assistants). * Part of a team that cares for adult patients (≥18 years). * Have the ability to order ECG. * Consent will be obtained from primary care clinicians. * Patients' data will be collected from electronic medical records (EMR). * Adult patients (≥ 18 years) undergoing an ECG for any indication over a period of 6 months will be included. Exclusion Criteria: * Patients with known cirrhosis based on noninvasive fibrosis assessment tests, liver biopsy or complications of decompensated disease, or with a documented history of cirrhosis identified by clinical notes.
