Eko Health: AI Digital Stethoscope Transforming Cardiac Detection

Eko Health is revolutionizing cardiovascular screening through FDA-cleared digital stethoscopes that combine advanced acoustic sensors with artificial intelligence, enabling primary care physicians and cardiologists to detect heart disease earlier and more accurately than traditional auscultation methods. By transforming the century-old stethoscope into an intelligent diagnostic tool, Eko democratizes access to expert-level cardiac assessment across primary care, telemedicine, and underserved communities.

The Cardiac Detection Challenge

Cardiovascular disease remains the leading cause of death globally, yet early detection—when treatment is most effective—remains challenging in primary care settings:

• Subtle heart sounds indicating valvular disease or heart failure are difficult to detect with traditional stethoscopes
• Provider skill variability in cardiac auscultation affects diagnostic consistency
• Limited specialist access in rural and underserved areas delays diagnosis
• Screening gaps mean many patients with treatable conditions go undetected until symptoms become severe
• Traditional stethoscopes provide no objective documentation or decision support

Studies show that up to 50% of significant heart murmurs are missed during routine physical examinations. Each missed diagnosis represents a lost opportunity for early intervention that could prevent heart failure, stroke, or premature death.

How Eko Health Works

Digital Acoustic Capture

Eko’s digital stethoscopes feature high-fidelity sensors that capture heart and lung sounds with 40x amplification compared to analog stethoscopes. This enhanced audio quality reveals subtle acoustic signatures invisible to conventional devices, enabling detection of:

• Heart murmurs indicating valvular stenosis or regurgitation
• Heart failure signatures including S3 and S4 gallops
• Arrhythmias detectable through irregular rhythms
• Pericardial friction rubs suggesting inflammatory conditions
• Abnormal lung sounds indicating pulmonary complications

Real-Time AI Analysis

Eko’s FDA-cleared AI algorithms analyze cardiac sounds in real-time during patient examinations:

• Structural heart disease detection: Identifies murmurs suggestive of aortic stenosis, mitral regurgitation, and other valvular conditions with high sensitivity
• Heart failure screening: Detects low ejection fraction with accuracy comparable to echocardiography in validation studies
• Atrial fibrillation detection: Identifies irregular rhythms requiring anticoagulation
• Analysis in seconds: AI processes heart sounds immediately, providing instant clinical decision support

The AI has been trained on hundreds of thousands of cardiac recordings paired with echocardiogram results, enabling it to recognize patterns associated with significant cardiac pathology.

Integrated ECG Capability

Eko’s flagship Core 500™ Digital Stethoscope combines cardiac auscultation with single-lead ECG:

• Simultaneous heart sound and ECG recording provides comprehensive cardiac assessment
• Rhythm analysis for arrhythmia detection
• ST-segment evaluation for ischemia screening
• Complete cardiovascular evaluation in one portable device

This dual modality assessment enables more thorough screening than either technology alone, particularly valuable in primary care and urgent care settings.

Clinical Workflow Integration

Seamless Documentation: Recordings sync automatically to EHR systems, creating permanent objective documentation of cardiac findings—a significant medicolegal advantage over traditional auscultation.

Telemedicine Enhancement: Physicians can capture heart sounds during in-person visits, then share recordings with specialists for remote consultation, or even conduct virtual cardiac assessments when combined with patient-operated devices.

Educational Tools: Side-by-side comparison of normal and abnormal heart sounds helps train medical students, residents, and practicing clinicians, improving auscultation skills.

Longitudinal Tracking: Serial recordings enable objective assessment of disease progression or treatment response over time.

Clinical Performance & Validation

FDA Clearance: Multiple FDA 510(k) clearances for heart murmur detection, heart failure screening, and atrial fibrillation detection validate clinical safety and effectiveness.

Published Evidence: Peer-reviewed studies demonstrate:

• 87-90% sensitivity for detecting structural heart disease requiring echocardiography
• Comparable accuracy to specialist cardiologists in murmur identification
• High negative predictive value reducing unnecessary echocardiogram referrals
• Improved detection rates in primary care settings where cardiac expertise is limited

Real-World Impact: Healthcare systems implementing Eko report 2-3x increase in significant cardiac findings detected during routine physicals, enabling earlier intervention and improved outcomes.
