I read this forum and I can understand your problem with the chest pain. Chest pain is only one of the possible signs of an impending heart attack. Doctors use several pieces of information to determine who is, and who isn't, having a heart attack. In addition to the description of your symptoms and your heart risk profile, doctors use the results of an electrocardiogram (ECG) and a blood test called cardiac troponin. But sometimes these don't immediately show abnormalities. So, what you describe to the doctor and your medical history are extremely important in determining the initial steps in your treatment.
Holter is a good start, but you need and echo and absolutely a chest ct-a bc of your age. Are you on bc?
