Chest pain accounts for approximately six million annual visits to emergency departments (ED) in the United States, making chest pain the second most common complaint . Patients present with a spectrum of signs and symptoms reflecting the many potential etiologies of chest pain. Diseases of the heart, aorta, lungs, esophagus, stomach, mediastinum, pleura, and abdominal viscera may all cause chest discomfort.
Clinicians in the ED focus on the immediate recognition and exclusion of life-threatening causes of chest pain. Patients with life threatening etiologies for chest pain may appear deceptively well, manifesting neither vital sign nor physical examination abnormalities.
This topic review will discuss life-threatening and common causes of chest pain, and provide an approach to the evaluation of chest pain patients in the ED. Detailed discussions of specific causes of chest pain, including the management of a suspected acute coronary syndrome in the ED are found elsewhere. (See "Initial evaluation and management of suspected acute coronary syndrome in the emergency department" and "Overview of acute pulmonary embolism in adults" and "Management of aortic dissection" and "Primary spontaneous pneumothorax in adults" and "Secondary spontaneous pneumothorax in adults" and "Cardiac tamponade" and "Boerhaave's syndrome: Effort rupture of the esophagus".)
