ROCHESTER, MN – November 5, 2025 – In a landmark development set to redefine healthcare diagnostics, Mayo Clinic researchers have unveiled an innovative artificial intelligence (AI) algorithm capable of detecting obstructive sleep apnea (OSA) with remarkable accuracy using standard electrocardiogram (ECG) results. Announced on November 4, 2025, with findings published in JACC: Advances, this breakthrough promises to make screening for this pervasive and often undiagnosed condition faster, cheaper, and significantly more accessible, particularly for women who frequently suffer from delayed or missed diagnoses.
This AI-powered ECG analysis represents a pivotal shift from traditional, cumbersome sleep studies, offering a non-invasive and efficient method to identify the subtle cardiac signatures of sleep apnea. The immediate significance of this innovation lies in its potential to dramatically improve early detection rates, leading to timely interventions that can mitigate the severe cardiovascular and other health risks associated with untreated OSA, thereby enhancing global public health.
Unpacking the Algorithm: A Deep Dive into AI-ECG Diagnostics
The core of Mayo Clinic's groundbreaking technology is a sophisticated deep convolutional neural network (CNN) model, aptly referred to as the "AI-ECG model." This advanced AI is trained to discern specific patterns within a routine 12-lead electrocardiogram, which captures the electrical activity of the heart. These patterns, imperceptible to the human eye, signify the subtle yet critical impacts of obstructive sleep apnea on heart muscle cells.
The algorithm's development was a meticulous process, leveraging a vast retrospective dataset of 11,299 patients from the Mayo Clinic. Each patient had undergone both a 12-lead ECG and a comprehensive sleep evaluation, with over 7,000 confirmed OSA diagnoses and 4,000 serving as controls. This extensive training allowed the AI to learn and identify the "OSA signature" within the ECG data. In test samples, the AI-ECG model achieved an impressive Area Under the Curve (AUC) of 0.80, with an accuracy of 73.7%, sensitivity of 77.0%, and specificity of 68.6%. Notably, the model exhibited superior performance in females (AUC: 0.82) compared to males (AUC: 0.73).
This AI-ECG approach starkly contrasts with traditional polysomnography (PSG), the current gold standard for sleep apnea diagnosis. PSG requires an overnight stay in a specialized sleep laboratory, involving numerous sensors and extensive physiological monitoring – a process that is expensive, time-consuming, and often inconvenient. While PSG provides comprehensive data, the AI-ECG offers a scalable, low-cost screening alternative that can be integrated into routine clinical practice, identifying individuals who warrant further, more definitive sleep evaluations. Initial reactions from the AI research community and industry experts have been overwhelmingly positive, recognizing its potential for widespread, low-cost screening and its robust performance, especially in addressing the diagnostic gap for women.
