Central chest pain can be caused by cardiac issues like angina or myocardial infarction, or non-cardiac issues like pulmonary embolism or esophageal disorders. A thorough history of the characteristics of the pain, including location, duration, aggravating/relieving factors, and associated symptoms can help determine the underlying cause. Key factors that help differentiate cardiac from non-cardiac chest pain include relationship to exertion and response to nitroglycerin.
