Is there a relationship between heart burn and heart attack?

Sometimes: Heart burn is a description of pain, a burning sensation in the chest. If it is related to exertion, it would be more likely to be a heart problem. If it is related to eating it is more likely to be gastrointestinal. Either way, it is sometimes hard to be sure without testing to exclude the heart so the symptom should be taken seriously and investigated.

No: There's no known association between acid-reflux, the condition that causes "heartburn", and heart attack. However, the chest discomfort in these two conditions can mimic each other. For instance, people with heartburn frequently feel more of a chest pressure, tightness, or pain than an actual "burning", and those with a heart attack may have classical reflux symptoms.

No: Although the symptoms of one could be mistaken for the other, heartburn and heart attack are unrelated. A heart attack occurs when heart muscle is damaged from sudden lack of blood flow. Heartburn refers to he discomfort caused by acid refluxing from the stomach up into the esophagus.

No: But they both cause chest pain that may feel the same and be in the same location. Err on the side of caution. Assume it's heart attack until proven otherwise.
