Intended Use

The Anumana Low Ejection Fraction AI-ECG Algorithm is software intended to aid in screening for Left Ventricular Ejection Fraction (LVEF) less than or equal to 40% in adults at risk for heart failure. This population includes, but is not limited to:
· patients with cardiomyopathies

  • patients who are post-myocardial infarction
  • · patients with aortic stenosis
  • · patients with chronic atrial fibrillation
  • · patients receiving pharmaceutical therapies that are cardiotoxic, and
    • postpartum women.

Anumana Low Ejection Fraction Al-ECG Algorthm is not intended to be a stand-alone diagnostic device for cardiac conditions, should not be used for monitoring of patients, and should not be used on ECGs with a paced rhythm.

A positive result may suggest the need for further clinical evaluation in order to establish a diagnosis of Left Ventricular Ejection Fraction (LVEF) less than or equal to 40%. Additionally, if the patient is at high risk for the cardiac condition, a negative result should not rule out further non-invasive evaluation.

The Anumana Low Ejection Fraction AI-ECG Algorithm should be applied jointly with clinician judgment.

Device Description

The Low Ejection Fraction AI-ECG Algorithm interprets 12-lead ECG voltage times series data using an artificial intelligence-based algorithm. The device analyzes 10 seconds of a single 12lead ECG acquisition, and within seconds provides a prediction of likelihood of LVEF (ejection fraction less than or equal to 40%) to third party software. The results are displayed by the third-party software on a device such as a smartphone, tablet, or PC. The Low Ejection Fraction AI-ECG Algorithm was trained to predict Low LVEF using positive and control cohorts, and the prediction of Low LVEF in patients is generated using defined conditions and covariates. The Low Ejection Fraction AI-ECG Algorithm device is intended to address the unmet need for a point-of-care screen for LVEF less than or equal to 40% and is expected to be used by cardiologists, front-line clinicians at primary care, urgent care, and emergency care settings, where cardiac imaging may not be available or may be difficult or unreliable for clinicians to operate. Clinicians will use the Low Eiection Fraction AI-ECG Algorithm to aid in screening for LVEF less than or equal to 40% and making a decision for further cardiac evaluation.

AI/ML Overview

Here's a breakdown of the acceptance criteria and the study proving the device meets those criteria, based on the provided FDA 510(k) clearance letter for the Low Ejection Fraction AI-ECG Algorithm:


Low Ejection Fraction AI-ECG Algorithm: Acceptance Criteria and Performance Study

1. Table of Acceptance Criteria and Reported Device Performance

Performance CharacteristicAcceptance CriteriaReported Device Performance (95% CI)
Sensitivity80% or higher84.5% (82.2% to 86.6%)
Specificity80% or higher83.6% (82.9% to 84.2%)
Positive Predictive Value (PPV)Not specified (derived metric)30.5% (28.8% to 32.1%)
Negative Predictive Value (NPV)Not specified (derived metric)98.4% (98.2% to 98.7%)

2. Sample Size Used for the Test Set and Data Provenance

  • Sample Size for Test Set: The clinical validation study included 16,000 patient records initially, though 2,040 records were excluded due to quality checks, resulting in a final analysis sample of 13,960 patient-ECG pairs.
  • Data Provenance: The data was retrospective, collected from 4 health systems across the United States.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications

The document does not specify the number of experts or their qualifications used to establish the ground truth for the clinical validation test set. The ground truth (LVEF <= 40% or > 40%) was derived from transthoracic echocardiogram (TTE) measurements. While TTE interpretation requires expertise, the document doesn't detail the method of expert review or consensus for these TTE results themselves for the test set.

4. Adjudication Method for the Test Set

The document does not specify an adjudication method (e.g., 2+1, 3+1) for the ground truth for the test set. The ground truth was established by TTE measurements.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done

No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. The study evaluated the standalone performance of the AI algorithm against a ground truth without human readers in the loop.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done

Yes, a standalone performance study was done. The reported sensitivity and specificity values are for the algorithm's performance alone in detecting low LVEF.

7. The Type of Ground Truth Used

The type of ground truth used for both training and validation was objective clinical measurements from Transthoracic Echocardiogram (TTE), specifically the Left Ventricular Ejection Fraction (LVEF) measurement. An LVEF of $\le$ 40% was defined as the disease cohort, and > 40% as the control cohort.

8. The Sample Size for the Training Set

The training set for the algorithm development consisted of 93,722 patients with an ECG and TTE performed within a 2-week interval. These were split into:

  • Training dataset: 50% of the 93,722 patients.
  • Tuning dataset: 20% of the 93,722 patients.
  • Set-aside testing dataset: 30% of the 93,722 patients (used for internal validation during development, distinct from the independent clinical validation study).

9. How the Ground Truth for the Training Set Was Established

The ground truth for the training set was established using LVEF measurements obtained from transthoracic echocardiograms (TTE). Specifically, for each patient, the LVEF measurement from the earliest TTE within a 2-week interval of an ECG was paired with the closest ECG recording. LVEF $\le$ 40% defined the disease cohort, and LVEF > 40% defined the control cohort. This data was identified from a research-use authorized clinical database from Mayo Clinic.

Algorithm Training

To develop the Anumana Low Ejection Fraction AI-ECG (Low EF ECG-AI) algorithm, 93,722 patients with an ECG and transthoracic echocardiogram (TTE) performed within a 2-week interval were identified from a research use authorized clinical database from Mayo Clinic. For each patient, the left ventricular ejection fraction (LVEF) measurement from the earliest TTE was selected and paired with the closest ECG recording within a 2-week interval of the TTE. The disease cohort was defined as LVEF ≤ 40% and consisted of 11% of the overall cohort. The control cohort was defined as LVEF > 40% and consisted of 89% of the overall cohort. The cohorts were split into training (50%), tuning (20%) and set-aside testing (30%) datasets. Within the set-aside test set, the sensitivity and specificity of the algorithm were 85.7% and 84.2%, respectively.

Performance analyses were also conducted in subgroups of age, sex, and race. Within the training set-aside test dataset, 91.2% of patients were White, 1.4% Black/African American, 1.3% Asian, 0.4% American Indian and 5.7% were of other or unknown races. Patients were 57.6% male and 43.4% female. The average age was 61.5 (± 16.4) years and 11.2% of patients were under age 40, 10.0% were 40-49, 18.1% were 50-59, 25.9% were 60-69, 22.3% were 70-79, and 12.5% were over 80.

Summary of Clinical Validation

Study Design

The performance profile of the Anumana Low Ejection Fraction AI-ECG (Low EF AI-ECG) algorithm was validated in a retrospective study of 16,000 patient records across 4 health systems across the United States and 16,000 patients. The objective of the study was to establish the diagnostic performance of the device for the purpose of detecting the presence of an EF ≤ 40% in a clinically and demographically diverse population. The sole inclusion criteria for a subject was age ≥ 18 and the availability of at least one digital 12-lead ECG paired with an echocardiogram with quantitative left ventricular ejection fraction (LVEF) information within 30 days following the date of the ECG. Candidate cases were identified in reverse chronological order from the date the site was activated. For each patient, the most recent echocardiogram was paired with the most recent ECG (without pacing present) acquired for that patient prior to the echocardiogram, up to the 30 days limit. Four models of 12-L ECGs (GE Dash 3000, GE MAC® 5500 Resting Analysis System, GE MAC VU360 Resting ECG, and Philips PageWriter TC70 ECG machines (model 860315) were represented in the ECG inputs to the algorithm.

Summary of Study Results

Each of the 4 sites contributed 4,000 patient-ECG pairs to a final pool of 16,000 patient-ECG pairs. The study sample was representative of the US population and was 65.9% White, 11.0%

K232699 Page 3 of 9

Page 7

Hispanic, 10.1% Black/African American, 5.3% American Indian or Alaska Native, 2.2% Asian, and 0.4% Native Hawaiian or Pacific Islander. The sample consisted of 52% male and 48% female participants. The average age as 66 and 11.6% of participants were under age 40, 9.2% were 40-49, 15.8% were 50-59, 22.8% were 60-69, 21.6% were 70-79, and 19% were over 80. A total of 2,040 records were excluded as a result of the quality checks performed by the Anumana Low Ejection Fraction AI-ECG (Low EF AI-ECG) algorithm.

Within this diverse study sample, a total of 1,096 LVEF ≤ 40% cases were identified (prevalence of 7.9%) from 13,960 samples. The Anumana Low EF ECG-AI device achieved a sensitivity of 84.5% (95% CI of 82.2% to 86.6%), a specificity of 83.6% (95% CI of 82.9% to 84.2%), a positive predictive value of 30.5% (PPV, 95% CI of 28.8% to 32.1%), and a negative predictive value of 98.4% (NPV, 95% CI of 98.2% to 98.7%).

Subgroup Analyses

Subgroup assessments of diagnostic performance were conducted to determine if there was heterogeneity in device performance across clinical sites, demographics, clinical characteristics, conduction disorders, ECG manufacturer, and ECG devices. To assess for heterogeneity, Breslow-Day tests for the strata were conducted on the odds ratio for condition presence given a positive ECG-AI result. The results are summarized in Table 2 below.

Table 2: Subgroup Analyses

Subgroup AnalysisResult of Test for Heterogeneity
Clinical SiteNot statistically significant
Biological SexNot statistically significant
Race/EthnicityNot statistically significant
Age GroupDiagnostic performance varied across age strata (p < 0.01). The diagnostic odds ratio was higher than the overall estimate in patients aged 40 to 69 years and lower in younger and older patients. In younger patients, sensitivity was lower while specificity was higher, whereas in patients of advanced age, sensitivity was higher while specificity was lower.
Clinical Characteristics• Diagnostic performance varied across body mass index strata (p = 0.02), with the lowest diagnostic performance observed in underweight (BMI <18.5 kg/m2) participants and the highest diagnostic performance observed in overweight (BMI 25+ to <30) and obese (BMI 30+) participants.• Diagnostic performance varied across certain elements of medical history derived from ICD9/ICD10 codes in patient medical records. The diagnostic odds ratio was lower in patients with prior history of heart failure (p<0.01), myocardial infarction (p<0.01) and coronary revascularization (p=0.07). In each of these cases, the disease prevalence was high (>17% for the three conditions) and the algorithm had higher sensitivity and lower specificity. This combination, at the higher prevalence values, resulted in robust positive predictive value (>35%) and negative predictive value (>94%).
