My mom just had weird chest pain? help?

My mom (51) was sitting down when she started feeling pain in the center of her chest, after 5 minutes she had to lay down and felt like she was going to faint. After that the pain left for the most part but now 30 minutes later she says there's a weird feeling when she breaths deep. Does anyone know is this Angina, a Heart Attack or Gall Bladder problems?
