Eko Low Ejection Fraction Tool (ELEFT)
Overview
The Eko Low Ejection Fraction Tool (ELEFT) is an innovative AI-powered algorithm developed by Eko Health in collaboration with Mayo Clinic. It is designed to aid clinicians in the early identification of individuals with Left Ventricular Ejection Fraction (LVEF) less than or equal to 40%, a key indicator of heart failure.
ELEFT integrates seamlessly with FDA-cleared Eko Digital Stethoscopes, such as the CORE 500™, to analyze both electrocardiogram (ECG) and heart sound (PCG) recordings during a routine physical examination. The software uses advanced signal processing and machine learning algorithms to provide a likelihood of low EF within approximately 15 seconds.
This tool is intended to assist healthcare providers in assessing LVEF ≤ 40% and is not a diagnostic tool on its own, but rather a screening tool to prompt further referral or diagnostic follow-up. By embedding rapid and accessible low ejection fraction detection into a familiar stethoscope exam, ELEFT aims to disrupt the status quo of delayed heart failure diagnoses, which often occur due to the inaccessibility or cost of traditional methods like echocardiography in primary care settings.
ELEFT is a component of Eko’s SENSORA™ Cardiac Early Detection Platform, which also includes FDA-cleared algorithms for detecting AFib and structural heart murmurs.

What Physicians Need to Know
ELEFT serves as a valuable screening tool, particularly in primary care and resource-limited settings, to identify patients at risk for low ejection fraction and potential heart failure earlier. It is crucial to remember that ELEFT is not a standalone diagnostic tool; a positive result necessitates further diagnostic evaluation, such as echocardiography, to confirm the diagnosis and guide treatment. Integrate ELEFT findings with a comprehensive clinical assessment, including patient history and symptoms, for optimal patient management. Early identification can facilitate timely specialist referrals and initiation of guideline-directed therapies, potentially preventing hospitalizations and adverse cardiac events.
ELEFT is integrated into Eko's SENSORAu2122 Cardiac Early Detection Platform, which also features other FDA-cleared algorithms for detecting atrial fibrillation and structural heart murmurs. The system relies on data input from Eko's digital stethoscopes and leverages a cloud-based API for data processing and result display across various devices.

What the Web Says
The Eko Low Ejection Fraction Tool (ELEFT) is an AI-powered algorithm integrated into Eko's smart stethoscopes, designed to help clinicians identify patients with a left ventricular ejection fraction (LVEF) of 40% or less, a key indicator of heart failure. Developed in collaboration with the Mayo Clinic, ELEFT analyzes 15 seconds of ECG and heart sound data during a routine physical exam, aiming to enable earlier detection of heart failure, especially in primary care settings where traditional diagnostic tools like echocardiography may be less accessible. The FDA cleared ELEFT in April 2024, and it is intended for use on patients aged 18 and older who are at risk for heart failure.
Overall: PositiveStrengths
- Enables early detection of low ejection fraction and potential heart failure during routine physical exams.
- Utilizes a familiar tool (stethoscope), making it accessible in various clinical settings, including remote and underserved areas.
- Provides rapid results (15 seconds), streamlining the diagnostic process.
- Developed in collaboration with the Mayo Clinic and has received FDA clearance.
- Can help prevent hospitalizations and adverse events by facilitating earlier intervention.
- Potentially reduces the need for expensive and specialized tests in initial screenings.
Limitations
- Some Reddit users have reported quality and durability issues with Eko stethoscopes, including loose eartips and connector breakage.
- The device is solely intended to analyze recordings collected by healthcare professionals or other operators with at least 5 years of experience in collecting clinical data.
- ELEFT is not intended to provide diagnostic quality output or identify arrhythmias.
- Requires physician or qualified healthcare professional review and interpretation for every analysis prior to clinical use.
- While it aids in detection, a confirmatory transthoracic echocardiogram is still needed for a definitive diagnosis of heart failure.
