Landmark TRICORDER study finds major gains in detection of heart failure, atrial fibrillation, and valvular disease with Eko Health's AI-enabled stethoscopes in routine exams.
SAN FRANCISCO, Sept. 11, 2025 /PRNewswire/ -- Eko Health, a leader in AI-powered cardiac and pulmonary disease detection, today announced groundbreaking results from the TRICORDER (Triple Cardiovascular Disease Detection Using an Artificial Intelligence Smart Stethoscope) study, led by Imperial College London and Imperial College Healthcare NHS Trust.
One of the largest randomized evaluations of AI ever conducted in routine care, TRICORDER spanned 205 NHS GP practices with 1.5 million registered patients, including more than 12,800 AI-stethoscope exams performed by nearly 1,000 providers. Results showed that when Eko Health's AI-enabled digital stethoscope was used as intended during routine exams, detection of major cardiac conditions increased dramatically over a 12-month period compared to the standard of care:
These findings, presented at the European Society of Cardiology Congress in Madrid, have drawn strong interest from providers and patient groups and underscore the potential for earlier cardiac disease detection and treatment.
"This is an elegant example of how the humble stethoscope, invented more than 200 years ago, can be upgraded for the 21st century," said Dr. Nicholas S. Peters, Professor of Cardiology and Director of the Health Impact Lab at Imperial College London. "By helping GPs identify heart disease in seconds, this technology offers patients earlier access to life-saving treatment, often before symptoms become severe. Demonstrating the benefits of real-world implementation of Eko's device is the real impact of the TRICORDER programme and the mission of The Health Impact Lab"
Unlike tightly controlled efficacy studies, TRICORDER was designed to mirror real-world practice. Providers used the device as they would in routine care, without prescriptive oversight. The findings demonstrate that integration of AI at the point of care can uncover hidden cardiac conditions that might otherwise remain undiagnosed until hospitalization or emergency care.
"The TRICORDER trial confirms what providers worldwide have experienced firsthand. AI can turn a routine exam using a stethoscope into one of the most powerful early detection tools in medicine," said Connor Landgraf, Co-Founder and CEO of Eko Health. "This is not about future promises; it's about saving lives today by giving clinicians actionable insights within seconds."
Using advanced sound technology and ECG sensors, Eko digital stethoscopes capture sounds and electrical signals from the heart, then transmit them to the cloud for AI analysis trained on tens of thousands of patients. The results are available instantly at the point of care.
With plans to expand use of Eko AI-enabled digital stethoscopes across practices in South London, Sussex, and Wales, TRICORDER marks a milestone moment in the adoption of AI-powered tools in everyday clinical care.
