GERD and heart attack symptoms can overlap, which is why chest discomfort should never be dismissed too quickly. Reflux commonly causes burning chest discomfort, but serious cardiac symptoms can also feel unusual.

GERD Is More Likely If

  • symptoms are burning in nature
  • symptoms worsen after meals
  • symptoms worsen when lying down
  • sour taste or reflux is present

Heart Attack Is More Concerning If

  • chest discomfort comes with shortness of breath
  • pain radiates to the jaw or arm
  • sweating or fainting happens
  • symptoms occur with exertion

Bottom Line

If there is any real concern for a heart attack, it is safer to get emergency evaluation.
