ABSTRACT
What if you could be alerted, perhaps through your smartphone, that you may be about to have a heart attack, stroke, or some other medical event-well before its onset? And that this warning would be based not on commonly recognized symptoms but on a sophisticated data analysis of your vital signs and other health information. In such a scenario, your medical data would be continuously monitored and scanned by powerful computers searching for complex patterns-the patterns of thousands of heart attack or stroke victims, for example, whose pre-event data looked just like yours do now. Alerted to the danger in real time, you could seek emergency medical attention.
