European Patent Granted for ECG-Based Assessment of Diastolic Function, Expands HeartSciences’ Patent Portfolio to More Than 45 Granted Patents

Patent covers machine-learning models that use ECG data to estimate echocardiogram parameters indicative of diastolic function

Southlake, TX, June 11, 2026 (GLOBE NEWSWIRE) — HeartSciences Inc. (Nasdaq: HSCS; HSCSW) (“HeartSciences” or the “Company”), a healthcare information technology (“HIT”) company focused on advancing electrocardiography (“ECG” or “EKG”) through the integration of artificial intelligence (“AI”), today announced the grant by the European Patent Office (EPO) of European Patent No. EP4252651, titled “Electrocardiogram-Based Assessment of Diastolic Function.” The patent covers machine-learning models and methods for computing quantitative estimates of echocardiogram parameters indicative of diastolic function using ECG data and patient demographic parameters.

“Securing European patent protection for ECG-based assessment of diastolic function is an important expansion of our AI-ECG intellectual property portfolio,” said Andrew Simpson, CEO of HeartSciences. “Diastolic dysfunction is an important indicator of cardiac disease that has traditionally required imaging-based assessment. This grant further reinforces our strategy of transforming the ECG into a far more valuable front-line cardiac screening tool and underlines the considerable embedded IP value in HeartSciences. We believe the breadth of our patent portfolio provides a meaningful commercial advantage as the field of AI-ECG continues to expand.”

The patented technology uses machine learning models, trained on ECG and echocardiography data, to estimate echocardiogram parameters indicative of diastolic function directly from a patient’s ECG.

The patent took effect as a Unitary Patent on April 29, 2026, and provides coverage in 19 European countries: Austria, Belgium, Bulgaria, Croatia, Denmark, Estonia, Finland, France, Germany, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Romania, Slovenia and Sweden. With this grant, HeartSciences’ intellectual property portfolio now includes more than 45 granted patents.
