State of the art AI technology can calculate a person's risk of suffering a heart attack just by listening to their VOICE, according to a new study. People who have a high pitched voice are more than twice as likely to suffer major heart problems related to clogged arteries, say scientists. Coronary heart disease is the most common cause of heart attack and is one of the leading causes of death for both men and women worldwide. It occurs when the heart's blood supply is blocked or interrupted by a build-up of plaque in the coronary arteries. Now scientists have developed a "powerful screening tool" dubbed the Vocalis Health algorithm to help identify those who are particularly at risk and may need close monitoring.
