Google and Verily Life Sciences shared the latest advance in computer vision to identify signs of heart disease. With an accuracy of 70 percent, early results from the AI trained on retinal scan images from more than 200,000 patients is as precise as methods that require blood tests for cholesterol, said Google Brain product manager Lily Peng. It's the latest example of AI being used to tackle the biggest killer in the world: heart disease. It takes more lives than any other cause of death -- 800,000 in the United States alone, according to the American Heart Association. To save lives, an AI army is joining the fight.
