Artificial Intelligence Revolutionizing Heart Health Diagnoses
A groundbreaking artificial intelligence algorithm, developed by experts at the Montreal Heart Institute, is proving to be as adept as, if not superior to, human interpretations of electrocardiograms (ECGs).
This innovative tool has the remarkable ability to identify disorders that may elude human observation, with symptoms that might only manifest months later, according to one of the project leaders.
Dr. Robert Avram, a prominent cardiologist at the ICM, highlighted the AI’s capability, stating, “We can identify conditions like heart failure, predict the risk of arrhythmia in individuals who currently show no signs of it but could potentially develop it in the future, or even detect genetic diseases that are traditionally challenging to diagnose through ECG readings. Thanks to our model, we can achieve this with remarkable accuracy.”
The DeepECG model, spearheaded by Alexis Nolin-Lapalme and Achille Sowa, was trained on over a million ECG results and subsequently validated across eleven international centers, making it the world’s first open-source foundational ECG model. This means that healthcare facilities and research institutions globally can customize the model to suit their local population, potentially uncovering new cardiac biomarkers even with limited data.
Dr. Avram emphasized the significance of this advancement, explaining, “While a cardiologist can already detect several diseases from an ECG, training a foundational model allows us to teach the algorithm to identify conditions that are invisible to the naked eye and typically go undetected through conventional medical means.”
The AI-powered DeepECG can pinpoint conditions that may escape even the keenest human eye, including reduced heart force, structural heart diseases like aortic stenosis or heart muscle dilation, and distinctive electrical patterns linked to hereditary heart conditions.
Despite its robust performance across a range of problems, the researchers noted a slight decrease in effectiveness with very rare conditions due to limited training data availability.
Dr. Avram illustrated the potential impact of this technology with a real-life scenario involving early detection of heart weakness in a patient scheduled for knee surgery, which led to timely intervention and treatment initiation, thereby enhancing the chances of recovery.
Contrary to concerns about AI replacing human roles, Dr. Avram emphasized that it enhances the existing workforce’s capabilities within resource-constrained settings.
The DeepECG system, currently in phase II clinical trials, aims to streamline cardiovascular diagnoses, improve access, speed, and accuracy, ultimately offering more efficient and personalized care to high-risk individuals.
