When you go to the hospital for chest pains or heart attack symptoms that come and go, what other test do they do, if the ekg is fine?

The rest of that work up would depend on what other symptoms you are describing at that time. It is likely that you would have some blood tests performed and it is possible that you may have x-rays, such as a chest x-ray or even a CT scan of the chest, among other possibilities. If you’re having chest pain do not ignore it, and get attention immediately. Good luck.

Blood work and possibly imaging is done depending on details in history and findings on exam. The work up is not geared towards finding a diagnosis, but rather to ruling out known life threatening conditions suggested at presentation and this is where going repeatedly to er in order to find a diagnosis is not productive, but rather frustrating.
