AI accurately detects cardiac dysfunction using smartwatch ECG: Study
USA: Based on their findings published in Nature Medicine, a team of researchers from the Mayo Clinic has opened up the possibility of using measurements obtained at home to find and treat patients (with cardiac dysfunction) before progressing to more-severe disease.
The proof-of-concept study found that an artificial intelligence (AI) algorithm trained to interpret single-lead electrocardiograms (ECGs) from Apple Watch helped accurately detect signs of subclinical left ventricular systolic dysfunction. Cardiac dysfunction is a potentially life-threatening and often asymptomatic condition.
AI algorithms have been demonstrated to have the potential to identify cardiac dysfunction, defined as ejection fraction (EF) ≤ 40%, from 12-lead ECGs; however, cardiac dysfunction identification using single-lead ECG of a smartwatch requires cardiac dysfunction identification using single-lead ECG of a smartwatch testing. Paul A. Friedman, Department of Cardiovascular Medicine, Mayo Clinic College of Medicine, Rochester, MN, USA, and colleagues, therefore, conducted a prospective study in which Mayo Clinics' patients were invited by email to download an iPhone application of Mayo Clinic that sends watch ECGs to a secure data platform. They also examined patient engagement with the study app and diagnostic use of the ECGs.
