A Breakthrough in
Low EF Detection

SENSORA™ Low EF helps detect signs of heart failure by flagging reduced ejection fraction in a physical exam.

Talk to Our Team

The future of low ejection fraction detection is here. Many cases of heart failure go undetected until symptoms are severe, leading to worse outcomes and higher healthcare costs.1 Now FDA-cleared, Eko’s Low EF AI enables healthcare professionals to identify signs of heart failure in at-risk patients during a stethoscope exam. SENSORA™ Low EF will be available in spring 2024.

More than 6 million people in the U.S. battle heart failure.²
1 in 4 Americans will develop heart failure in their lifetime.3
Heart failure causes nearly 2 hospitalizations every minute (2,880 per day).4

Transform the Physical Exam

Transform the Physical Exam
Detect Low EF Prior to an Echocardiogram

Echocardiography is often inaccessible in primary care settings due to required training, limited time, and added cost. SENSORA™ Low EF pairs the Eko stethoscope with powerful low EF detection AI, enabling rapid identification of reduced ejection fraction in a primary care setting. In the case of a positive result, providers can consider a referral for an echocardiogram or cardiology consult.

Identify Low EF in Seconds

Time is a precious resource in primary care. SENSORA™ Low EF will enable clinicians to analyze heart sound and ECG data for ejection fraction below 40% in 15 seconds, ensuring minimal interruption to clinical workflow. By incorporating AI into the stethoscope exam, SENSORA™ Low EF helps keep visits on track without a major learning curve.

Robust AI Training & Validation

Eko’s Low EF AI was trained on a proprietary dataset of over 100,000 ECGs and echocardiogram pairs from unique patients, and was clinically validated in a multi-site, prospective clinical study of 3,456 patients, achieving an AUROC of 0.835 for detection of LVEF <40%, 74.7% sensitivity and 77.5% specificity, demonstrating a strong ability to differentiate between low and normal EF.

Independent Clinical Research

An independent validation of Eko’s Low EF AI by the Imperial College London, published in Lancet Digital Health, reported an AUROC of 0.85 for detection of LVEF below 40%, 84.8% sensitivity, and 69.5% specificity when deployed on over 1,050 patients across multiple real-world settings. This research prompted the UK NHS and Imperial College London to extend Eko's deployment to over 100 clinics in London and Wales.
