Heartburn vs heart attack
Someone who has gastroesophageal reflux disease (acid reflux) can experience heartburn. A painful burning occurs behind the breastbone and you may feel pain that goes up toward your throat. When you lie down or bend over, the pain will get worse. You may have the feeling that food is entering back into your mouth. These symptoms usually occur after you finish a large or spicy meal.
Angina (when there is not enough blood flowing to your heart) can cause pain in your chest. Angina or a heart attack can cause tightness, squeezing, pressure, or dull pain in the middle of the chest. The pain can radiate to your neck, shoulders, or arms. Moreover, you may have trouble breathing, have an irregular heartbeat, or feel lightheaded, weak, or dizzy. Extreme stress or physical activity can lead to these symptoms.
