Angina is chest pain caused by a lack of blood flow to the heart, while heartburn is a burning sensation behind or directly below the breastbone (sternum). The sensations can be very similar, but its very important to be able to tell the difference.

Angina requires medical attention, as it can be an indication of a heart disease or a heart attack. Heartburn, in mild cases, doesnt typically require medical attention, and its rarely an urgent situation. Heartburn, while not serious, is an inconvenience and discomfort for those who experience it. It can also lead to more serious conditions if episodes occur frequently over long periods of time. For instance, ulcers can develop from the damage caused by stomach acid in the esophagus and esophageal cancer has been attributed to frequent heartburn.

Heartburn Symptoms
Heartburn is best described as a burning sensation in the middle of the chest or directly below the breastbone. This burning typically responds to antacids and it doesnt radiate to the arms or shoulders, although the pain can travel up the neck. Heartburn can also cause an acidic, salty or sour taste in the mouth and can sometimes cause regurgitation.

Heartburn is caused by the malfunctioning of the lower esophageal sphincter. Understanding the physiological process behind heartburn can be helpful in differentiating the pain from angina. The lower esophageal sphincter acts like a lid that prevents the contents of the stomach from traveling up the esophagus. If this sphincter doesnt close properly, stomach acids can leak out and into the esophagus, creating the burning sensation classic of heartburn.

Angina Symptoms
Angina is pain in the chest, less like a burning, that frequently radiates down the arms and into the shoulders. Angina can also involve a feeling of tightness and pressure in the chest. Lightheadedness, dizziness and shortness of breath may also accompany angina. The presence of these symptoms is a definite distinction between heartburn and angina symptoms.

Patients experiencing angina may experience heartburn or indigestion as a symptom. Heartburn is rarely the only symptom of angina, so patients experiencing heartburn accompanied by other symptoms of angina should seek medical attention to ensure they are not suffering from a serious condition.

Angina can occur as a result of stress or immediately following an emotional outburst. While stress is said to be a contributing factor to heartburn as well, angina can be identified if it immediately follows a highly stressful situation and comes on suddenly.
