Chest pain is pain or discomfort in the chest, typically the front of the chest.[1] It may be described as sharp, dull, pressure, heaviness or squeezing.[3] Associated symptoms may include pain in the shoulder, arm, upper abdomen, or jaw, along with nausea, sweating, or shortness of breath.[1][3] It can be divided into heart-related and non-heart-related pain.[1][2] Pain due to insufficient blood flow to the heart is also called angina pectoris.[5] Those with diabetes or the elderly may have less clear symptoms.[3]
Serious and relatively common causes include acute coronary syndrome such as a heart attack (31%), pulmonary embolism (2%), pneumothorax, pericarditis (4%), aortic dissection (1%) and esophageal rupture.[3] Other common causes include gastroesophageal reflux disease (30%), muscle or skeletal pain (28%), pneumonia (2%), shingles (0.5%), pleuritis, traumatic and anxiety disorders.[3][6] Determining the cause of chest pain is based on a person's medical history, a physical exam and other medical tests.[3] About 3% of heart attacks, however, are initially missed.[1]
Management of chest pain is based on the underlying cause.[1] Initial treatment often includes the medications aspirin and nitroglycerin.[1][4] The response to treatment does not usually indicate whether the pain is heart-related.[1] When the cause is unclear, the person may be referred for further evaluation.[3]
Chest pain represents about 5% of presenting problems to the emergency room.[3] In the United States, about 8 million people go to the emergency department with chest pain a year.[1] Of these, about 60% are admitted to either the hospital or an observation unit.[1] The cost of emergency visits for chest pain in the United States is more than US$8 billion per year.[6] Chest pain accounts for about 0.5% of visits by children to the emergency department.[7]
