The device analyzes the results of a 12-lead ECG administered as part of routine care to provide clinicians with insight into a patient's risk of future atrial fibrillation and/or atrial flutter events. When interpreted in conjunction with other available clinical information this can support clinicians in pursuing early and proactive diagnoses of AFib and atrial flutter with the goal of enabling improved clinical management of these conditions and their associated health risks.
AFib, which is a leading cause of stroke, is frequently unrecognized and untreated. Currently, there are no available devices to help physicians identify asymptomatic patients without a known history of cardiac arrhythmia who are at increased risk of future AFib, which carries other health risks including stroke and death. The Tempus ECG Analysis Platform is tackling that challenge by analyzing results of a widely-used clinical test, the 12-lead ECG, with software that identifies patients at increased risk of developing AFib or atrial flutter within the next 12 months.
A team of Geisinger and Tempus scientists and clinicians recently published a related study in Circulation, which showed that artificial intelligence can predict risk of new AFib and AFib-related stroke. For this research study, the combined team of data scientists and medical researchers used 1.6 million ECGs to train a deep neural network to predict, among people without a previous history of AFib, who would develop it within the next 12 months. In people with no history of AFib that went on to have an AFib-related stroke, nearly two thirds would have been predicted to be at high-risk before the stroke.
"In granting our request for Breakthrough Device designation, the FDA is helping bring the power of artificial intelligence to patients, with new, smarter tools that can support clinicians in predicting future clinical events," said Joel Dudley, Ph.D., Chief Scientific Officer of Tempus. "Every year, hundreds of millions of ECGs are performed in the U.S. to detect cardiac abnormalities as part of routine clinical care. We are making ECGs smarter so that they can also identify the risk of future clinical events of interest, such as AFib, thus enabling clinicians to act earlier in the course of disease and improve patient outcomes."
