Multiple. Heartburn is the most common cause of this; try zantac (ranitidine) & avoid spicy foods. I'm glad that your heart has checked out and your chest x-ray was normal. This could be esophageal spasm. One funny/strange cause in women with large breasts is the stabbing of underwire bras straight into the sternum - that may make it feel like you're having a heart attack! See your fp to investigate other possibilities!
Several things. Could be related to esophagus - acid reflux common. Reflux more likely with smoking, sodas, lying down right after eating, pregnancy), you might notice acid or metal taste in mouth in am when you awaken. If pain goes to back, this could be your aorta (needs quick check up - risk higher with high BP and atherosclerosis - usually older people).
