A recent study has revealed that applying artificial intelligence (AI) techniques to cardiac ultrasound data can significantly improve the identification of patients suffering from advanced heart failure.This groundbreaking research, conducted by teams from Weill Cornell Medicine, Cornell Tech, and NewYork-Presbyterian, presents a potential solution for a condition that often goes undiagnosed due to the complexities involved in its detection.
