Why the Algorithm Did Better in Heart Attacks

Deid and his co-author designed an algorithm that would not only find high and low risk heart attack patients, but that could also do something else. Doctors were actually very, very good at honing in on the risk factors that we all learn about in medical school. They tested older people more. They tested people with known risk factors more. And in fact, they were indistinguishable from the algorithm if they only looked at a small number of variables.
