In case of chest tightness and chest pain, it is recommended to visit the emergency medicine department or chest pain clinic to clarify the cause of chest tightness and chest pain. Some chest tightness and chest pain, such as acute myocardial infarction, acute pulmonary embolism, and aortic coarctation, are high-risk chest pains that require a clear diagnosis as soon as possible so that targeted treatment can be given. Going to the emergency internal medicine department or chest pain clinic can make a clear diagnosis of these chest pains in a short period of time, and a clear diagnosis requires treatment in the relevant specialty as soon as possible. In the case of patients with acute myocardial infarction, reperfusion therapy should be given as soon as possible. For other non-cardiogenic low-risk chest pain, a visit to the relevant specialty is an option after the cause is clarified.
