Heartburn is a burning sensation in the chest behind the breastbone. This accounts for the "heart" in heartburn. Other than the name and the location, heartburn is not related to chest pain (angina) due to heart disease. Nevertheless, while chest pain or chest pressure may indicate acid reflux, it is right for anyone with this kind of pain or discomfort to seek urgent medical evaluation. Possible heart conditions must always be excluded first.
