Is it heartburn or a heart attack?
Don’t ignore the possibility that chest pain may mean a heart attack instead of heartburn. GERD symptoms can mimic the pain of a heart attack or angina (chest pain caused by diminished blood flow through the coronary arteries). This is especially true when the sensation is constricting rather than burning in nature. It can be dangerous to assume that your chest pain is caused by acid reflux, even if you already have GERD.
People with known GERD should always seek medical attention if they experience chest discomfort caused by exercise, as it may signal either angina or a heart attack. Also, pay attention to how severe your chest pain is and how long it lasts. If you feel a severe, pressing, or squeezing discomfort, it may be a heart attack. And heart attack pain lasts a while. If the pain goes away after five to 10 minutes, it probably is not a heart attack. Still, it could be angina, which does require a visit to the doctor—and treatment.
If you have any chest pain symptoms that are unusual for you, or if you are concerned that you may be having a heart attack, call 911 or go to the nearest hospital
