By the way, doctor: Emergency care for chest pain
Q. If you have chest pain or discomfort, how do you know if it is serious enough to warrant emergency medical attention?
A. The sad truth is that there's no easy way to tell. There are dozens of mimickers of a heart attack. One of the most common is gastroesophageal reflux disease (GERD), and it is difficult even for physicians to distinguish between the two.
