I am having pain in right side of chest feels more like gas but ould it be a heat attack?

Risk factors. Heart disease is the number one killer in the United States. If you are having chest pain, and shortness of breath, you should call 911 immediately and call a loved one to be with you. Your risks of heart attack depend on your personal risk factors, as well as your medical history, and your family medical history. If several people in your family have had heart attacks, your risk is increased.
Highly unlikely. Heart attack pain occurs at the left and not the right side. Thus the pain is likely from elsewhere (gallbladder?).
