Well and its not a panacea, its a diagnostic device. This can only helps to mitigate the 50% of cases of heart disease where normal diagnostic measurements gave no advance notice before the heart attack. So its huge that that 50% could know now that a heart attack is coming, but what do you do with that knowledge? Its still up to the patient to make lifestyle changes and take preventative measures. They still havent invented the device that will diet and excercise for you LOL.
