Can Artificial Intelligence Identify Your Next Heart Attack?

Cardiac pain originates from the heart muscle, most typically when blood flow to the heart (through vessels called coronary arteries) become blocked. In the heart muscle, there are nerve endings which transmit signals to the brain which get interpreted as chest pain. Unfortunately, just like other pain arising in other organs in the body, cardiac pain is poorly localized. Think of when you had stomach cramps after eating some food you probably shouldn't have--the pain is often vague and generalized, as opposed to being isolated to one specific location. Furthermore sensations arising from other organs in the chest, such as the esophagus, can produce pain indistinguishable from cardiac pain.
