Aortic StenosisNCT06580158
AI in Outpatient Practice for Diagnosing Aortic Stenosis and Diastolic Dysfunction
An observational study of Aortic Stenosis and Diastolic Dysfunction, run by Mayo Clinic at 1 site in United States.
Trial summary
Two recently developed artificial intelligence-enabled electrocardiogram (AI-ECG) models have been developed to detect aortic stenosis (AS) and diastolic dysfunction (DD). AI-ECG for AS has a sensitivity of 78% and specificity of 74%, and AI-ECG for DD has a sensitivity of 83% and specificity of 80%. Read more about this study

About this study
Official title: The Clinical Utility of Artificial Intelligence-enabled Electrocardiograms in the Outpatient Practice - Diagnosing Aortic Stenosis and Diastolic Dysfunction
Two recently developed artificial intelligence-enabled electrocardiogram (AI-ECG) models have been developed to detect aortic stenosis (AS) and diastolic dysfunction (DD). AI-ECG for AS has a sensitivity of 78% and specificity of 74%, and AI-ECG for DD has a sensitivity of 83% and specificity of 80%. However, these models have never been prospectively applied to diagnose AS or DD, which may be useful for patients and providers from a diagnostic and prognostic perspective and especially in settings where access to higher- level medical care is limited. In this study, we aim to determine the clinical utility of these AI-ECG models by prospectively applying them to an outpatient cohort and then completing a focused point-of-care ultrasound to evaluate those who are AI-ECG positive for AS and DD.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
AI-ECG DashboardDevice
Patients standard of care ECG's will be processed through the AI-ECG Dashboard
Point of care ultrasound (POCUS)Diagnostic test
Patients will undergo a ultrasound to confirm diagnosis of atrial stenosis or diastolic dysfunction.
| Study group | Role | What they receive |
|---|---|---|
| Patients who are completing an outpatient electrocardiogram (ECG) at the Mayo Clinic. | Not described Receives: Device: AI-ECG Dashboard; Diagnostic Test: Point of care ultrasound (POCUS) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of patients with positive AI-ECG
Positive AI-ECG will be determined by the sensitivity, specificity, positive predictive value, and negative predictive value.
Measured: Baseline
Number of studies with reasonable image quality in patients with positive AI-ECG
Image quality will be determined by sonographers at the time of imaging and will be scored on a scale from 1-4:
- Excellent , sufficient for publication
- Good, sufficient for data analysis
- Fair, just enough for data analysis without complete views
- Poor, not usable for data analysis
Measured: Baseline
Secondary outcomes (1)
Number of times the AI ECG and TTE (transthoracic echocardiogram) are statistically comparative
Will be compared using parametric (2-sample t-test) and non-parametric tests (Wilcoxon rank sum test) for continuous variables, and the χ2 test or Fisher exact test for nominal variables. A p-value of < 0.05 will be categorized as significant for the statistical analysis
Measured: Baseline

Clinical summary

AI-ECG for AS has a sensitivity of 78% and specificity of 74%, and AI-ECG for DD has a sensitivity of 83% and specificity of 80%.

How can a doctor refer a patient or contact the research team?
Contact Brian Rudquist ((507) 538-5146, Rudquist.Brian@mayo.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of patients with positive AI-ECG (time frame: Baseline). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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.
How often is this information updated?
