Gastrointestinal Causes


Pains originating from the digestive tract often can mimic heart pains. Acid produced in the stomach can sometimes reflux, or back up into the esophagus, the long tube that connects the mouth to the stomach. This can cause discomfort in the upper stomach or around the breastbone. Acid reflux can irritate and inflame the esophagus, a condition known as esophagitis. It occurs after a meal or when one lies down. One clue that acid reflux may be the cause of chest pain is that the discomfort often is relieved by the use of an antacid such as Maalox® or Mylanta®.
Another cause of pain originating from the digestive tract is an ulcer, an erosion of the lining of the stomach or duodenum, the first part of the small intestine. Ulcers can result from heavy alcohol consumption, or chronic use of nonsteroidal anti-inflammatory agents (NSAIDs), and pain medications, such as ibuprofen (Motrin®) and naproxen sodium (Aleve®, Naprosyn®). Due to potentially severe gastrointestinal and cardiovascular side effects, NSAIDs should only be used as instructed.
Ulcers may also develop without a clear cause. As with acid reflux, the ulcer pain can cause discomfort in the upper abdomen, can be triggered by eating, and is sometimes relieved with antacids.
Musculoskeletal Causes The chest contains many muscles, bones, tendons, and cartilage (the rubbery tissue that connects muscles and bones). Strains or sprains to any of these can cause chest pains. Chest pains associated with musculoskeletal injury are typically sharp and confined to a specific area of the chest. They may be brought on by movement of the chest and/or arms into certain positions, and often are relieved by changing position. These pains can be triggered by pushing on part of the chest and often become worse when taking a deep breath. These pains usually last only seconds, but can persist for days.
Pulmonary Causes Pneumonia is an infection that develops in the lungs. It can lead to inflammation of the lung tissue or the tissue that surrounds the lung, a condition called pleuritis. Both conditions can cause chest pains. The pains of pneumonia and pleuritis are often made worse by deep breaths or coughing.
A rare but life-threatening condition that affects the lungs is pulmonary embolism, a blood clot that develops in a vein in the pelvis or legs. If part of the clot breaks free, it can travel through the bloodstream and into the lungs, where it may block the flow of blood in part of the lung. This can cause sudden chest pains and shortness of breath. Although blood clots can develop in people with no obvious risk factors, people considered to be at increased risk include those who remain immobile for long periods (e.g., bed-bound patients, people who sit through long-distance plane trips), cancer patients, and women who use birth control pills and smoke. Pulmonary embolism is a serious condition that requires immediate medical attention
