Publication number: 20240081653Abstract: Systems, methods, devices, and techniques for estimating a heart disease prediction of a mammal. An electrocardiogram (ECG) procedure is performed on a mammal, and a computer system obtains ECG data that describes results of the ECG over a period of time. The system provides a predictive input that is based on the ECG data to a predictive model, such as a neural network or other machine-learning model. In response, the predictive model processes the input to generate an estimated heart disease predictive characteristic of the mammal. The system outputs the estimated heart disease prediction of the mammal for presentation to a user.Type: ApplicationFiled: October 31, 2023Publication date: March 14, 2024Applicant: MAYO FOUNDATION FOR MEDICAL EDUCATION AND RESEARCHInventors: Itzhak Zachi Attia, Paul A. Friedman, Francisco Lopez-Jimenez, Suraj Kapa

Publication number: 20220218289Abstract: Apparatuses and methods are provided to predict or diagnose an ischemic event, such as a stroke or a transient ischemic attack (TIA). A machine-learning model such as a neural network is generated that allows for recognition of an ECG consistent with an ischemic event. A system is trained and used to process a recording of ECG data from a patient to generate a prediction indicating a likelihood that the patient will experience a stroke. In other examples, a system is trained and used to process a recording of ECG data from a patient and detect an ischemic event for the patient who did not appear to have such an ischemic event.Type: ApplicationFiled: March 31, 2022Publication date: July 14, 2022Applicant: Mayo Foundation for Medical Education and ResearchInventors: Itzhak Zachi Attia, Paul A.

Publication number: 20220125366Abstract: A system obtains a maternal electrocardiogram (ECG) signal that represents an ECG of a pregnant mother during a first time interval. The system further obtains a mixed maternal-fetal ECG signal that represents a combined ECG of the mother and her fetus during the first time interval; processes the maternal ECG signal and the mixed maternal-fetal ECG signal to generate a fetal ECG signal that represents the ECG of the fetus during the time interval, the fetal ECG signal substantially excluding the maternal ECG signal; and provides an output based on the fetal ECG signal.Type: ApplicationFiled: January 7, 2022Publication date: April 28, 2022Inventors: Paul A. Friedman, Dorothy J. Ladewig, Itzhak Zachi Attia, Kyle D. Traynor

Publication number: 20210401347Abstract: Systems and methods for assessing the condition of a heart of an individual. A system obtains electrocardiogram (ECG) data that describes a result of an ECG of the individual. The ECG data can be provided to a machine-learning model, which processes the data and generates an output indicative of the condition of the heart. The output relates to a level of troponin in a bloodstream of the individual. The system can then provide the output of the machine-learning model to a post-processing resource.Type: ApplicationFiled: June 24, 2021Publication date: December 30, 2021Inventors: Paul A.
