Researchers are developing artificial intelligence models to improve the detection of various cardiac conditions through electrocardiograms (ECGs). At Wake Forest University School of Medicine, an AI model was developed to identify three specific types of heart failure—reduced ejection fraction, mildly reduced ejection fraction, and heart failure with preserved ejection fraction (HFpEF)—using standard ECGs. The model, trained on over one million ECGs, showed potential for use in wearable devices as its single-lead version performed nearly as well as the 12-lead version. Corresponding author Oguz Akbilgic, Ph.D., stated, “Our AI model can detect various types of heart dysfunction from a simple, single-lead ECG alone.” In a study published in ‘Nature’, researchers at the University of California, Berkeley, developed an algorithm to identify hidden electrical patterns to improve the detection of sudden cardiac death risk. Trained on over 440,000 Swedish ECGs and death certificate data, the model was validated using records from the United States and Taiwan, demonstrating higher precision than standard clinical methods in identifying high-risk individuals. Further advancements include an AI tool capable of detecting heart disease, such as heart failure and valvular disease, in less than two seconds using a standard ECG. Presented at the European Society of Cardiology congress in Munich, the tool was trained on data from millions of patients. In a clinical trial involving 67,000 patients in the United States, the technology identified up to 81% of certain conditions, offering a potential alternative to the long wait times often associated with echocardiograms. Researchers from Imperial College London noted that while the tool is not intended to replace definitive diagnoses, it could serve as a critical screening mechanism to prioritize high-risk patients for urgent medical intervention, identifying up to 90% of valvular disease cases.
