Likewise, individuals who think that they are experiencing heartburn may actually be having a heart attack. Therefore, patients may think they are experiencing pain of a cardiac origin when the pain is, in fact, coming from the esophagus. SR It is often difficult to distinguish between cardiac and esophageal causes of chest pain based upon symptom presentation alone because the nerves that supply the heart also supply the esophagus. G&H How are cardiac and esophageal causes of chest pain differentiated? In this sensory disorder, the muscle, nerve, and receptors of the esophageal wall are overly sensitive.įinally, anxiety or an underlying psychiatric disorder can manifest as chest pain in some individuals. The third cause of esophageal chest pain, which has been a focus of my research for the last one-and-a-half decades, is an abnormal sensory function of the esophagus called esophageal hypersensitivity. Esophageal chest pain can also occur when the esophagus undergoes a strong spasm caused by a motility disorder of the esophagus. Reflux of acid can present with chest pain, heartburn, or swallowing difficulties chest pain is only 1 manifestation of this condition. The most common esophageal cause of pain is gastroesophageal reflux disease. The 3 main causes of esophageal chest pain result from an underlying disturbed nerve sensation and muscle and mucosal dysfunction. Once cardiac, muscular, and pulmonary conditions have been excluded, the vast majority of patients are found to have an esophageal source for their chest pain. Chest pain can also be triggered by pulmonary conditions such as an infection in the lungs. Muscular skeletal causes are common sources of chest pain. For example, an individual who is exercising after a period of physical inactivity may experience discomfort, heaviness, chest pain, and possibly even damage or trauma. Once a cardiac source of pain has been excluded, a variety of other sources should be considered, such as muscular skeletal or pulmonary causes. A cardiac source is the most concerning cause, as it is the most life-threatening thus, it must be excluded as soon as possible. SR Chest pain can arise from a number of disorders. G&H What are the various causes of chest pain?
