About this study
This study investigates the clinical efficacy of a non-invasive screening protocol using AI-ECG and CT-ECV analysis for cardiac amyloidosis. The study targets on atrial fibrillation(AF) patients with "red-flag" indicators.
Participants are randomized 1:1 into either an early screening or usual care group.
- Early screening group : AI- ECG and/or CT-ECV analysis + AF treatment
- Usual care group : AF treatment Both groups followed for 2 years to compare CA detection rates and clinical outcomes.
Read the detailed description
This study is a prospective randomized trial designed to evaluate the clinical utility of non-invasive early screening for cardiac amyloidosis (CA) using AI-ECG and CT-ECV in patients with atrial fibrillation (AF). The study primarily targets patients presenting with "red-flag" signs, such as heart failure symptoms, ECG findings of low voltage or pseudo-infarction, Troponin T > 0.03 ng/L, NT-proBNP > 332 pg/mL, LV wall thickness > 12 mm, a history of carpal tunnel syndrome or spinal canal stenosis, or proteinuria (e.g., UACR ≥ 300 mg/g, 24-hour proteinuria ≥ 0.5-1.0 g/day, or nephrotic-range proteinuria > 3.5 g/day).
The objective is to assess whether early screening improves the detection rate of CA and whether such early detection and subsequent treatment can improve clinical outcomes for patients. Subjects who meet the inclusion and exclusion criteria and provide informed consent will be randomly assigned to either the Early Screening Group or the Usual Care Group in a 1:1 ratio for comparative analysis. Participants will be allocated using stratified block randomization (allocation ratio 1:1) with a computer-generated random number sequence. Stratification variables, including age (age ≥ 75 vs. < 75 years) and sex.
Upon enrollment, all patients will undergo a baseline evaluation encompassing demographic information, medical history, and medication status, along with blood tests (e.g., NT-proBNP, troponin, creatinine). Additionally, AI-ECG analysis using standard 12-lead ECG or ECV analysis using cardiac CT will be performed. For AI-ECG analysis, the Mayo Clinic AI-ECG algorithm will be utilized; raw ECG data will be transmitted, and results will be received only for those patients who have provided specific consent. Patients who test positive in the AI-ECG analysis or cardiac CT-ECV analysis will undergo further diagnostic workup, including SPEP, UPEP, IFE, Free Light Chain Assay, and 99mTc-DPD scintigraphy. For those who test positive in these subsequent evaluations, definitive diagnosis will be attempted through endomyocardial biopsy or genetic testing.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
AI-ECG analysisDiagnostic test
Artificial Intelligence-enhanced Electrocardiogram (AI-ECG), developed by Mayo Clinic, is gaining attention as a non-invasive screening tool. AI-ECG predicts myocardial amyloid deposition based on a standard 12-lead ECG with high accuracy, AUC 0.84(95% CI 0.82-0.86) In particular, it demonstrated superior performance with an AUC of 0.9 or higher in ECGs exhibiting low voltage or pseudo-infarction patterns, suggesting its potential to detect the disease even before structural changes become apparent.
CT-ECV analysisDiagnostic test
Myocardial Extracellular Volume (CT-ECV) analysis using cardiac CT is a tissue characterization technique that can be easily added to conventional cardiac CT protocols, enabling the quantification of myocardial fibrosis or infiltrative diseases. Among 874 subjects who underwent coronary CT, 12.4% exhibited a CT-ECV of ≥ 35%, and cardiac amyloidosis was incidentally discovered in 14.3% of these individuals.
Atrial fibrillation treatmentOther
Standard care and treatment in accordance with established AF guidelines.
| Study group | Role | What they receive |
|---|---|---|
| Early screening group | Experimental | AI-ECG and/or CT ECV analysis with standard atrial fibrillation treatment Receives: Diagnostic Test: AI-ECG analysis; Diagnostic Test: CT-ECV analysis; Other: Atrial fibrillation treatment |
| Usual care group | Active comparator | Standard atrial fibrillation treatment Receives: Other: Atrial fibrillation treatment |
What is being measured
The primary outcome is the main question the study is designed to answer.
Cardiac amyloidosis(CA) detection rate
CA detection rate in the early screening group based on AI-ECG and CT-ECV results The superiority hypothesis (detection rate of the early screening group > control group) will be tested, utilizing the chi-squared test or Fisher's exact test as the primary analysis. Effect sizes will be reported as the difference in proportions, odds ratio (OR), and relative risk (RR), along with 95% CIs and p-values.
Measured: From enrollment to the 2 year follow-up
Secondary outcomes (2)
Diagnostic Sensitivity and Specificity of AI-ECG alone, CT-ECV alone, and the combined Model
Compare the diagnostic sensitivity and specificity of each model, the difference in proportions between groups will be analyzed as a primary analysis using the chi-squared test or Fisher's exact test. Furthermore, since the sensitivity and specificity of the AI-ECG, CT-ECV, and combined models are paired indicators derived from the same subjects, the McNemar test will be used for the comparison of sensitivity and specificity between models. In cases where it is necessary to adjust for covariates (e.g., age, sex, NT-proBNP) or to consider repeated measures/correlation structures, a logistic regression analysis based on Generalized Estimating Equations (GEE) with subject IDs as clusters will be performed to compare model effects.
Measured: From enrollment to 2 year follow-up
Correlation of AI-ECG/CT-ECV values with other screening results in patients with confirmed CA
In patients with a confirmed CA, the association between AI-ECG scores/probabilities, CT-ECV (continuous), and clinical findings-such as biopsy results (if available), degree of DPD uptake (e.g., grade), and SPEP/UPEP/IFE results (positive/negative or quantitative values)-will be evaluated using Spearman correlation analysis and, if necessary, logistic or linear regression analysis.
Measured: From enrollment to 2 year follow-up

Questions about this trial
What is this clinical trial studying?
A study testing AI-ECG analysis, CT-ECV analysis and Atrial fibrillation treatment in people with Atrial Fibrillation (AF) and Cardiac Amyloidosis, run by Samsung Medical Center at 1 site in South Korea.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 5 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Ju Youn Kim, Ph.D (82+ 10-5482-7307, kzzoo921@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Cardiac amyloidosis(CA) detection rate (time frame: From enrollment to the 2 year follow-up). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07567508, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
