If there is a sudden pain in the chest that lasts for a long time and is more intense, it is important to exclude the occurrence of acute myocardial infarction and it is recommended to check the electrocardiogram and myocardial enzymes. If myocardial enzymes are elevated or if there is a dynamic evolution of the ECG, coronary angiography can be performed. If the patient has sudden pain of relatively short duration, the patient has no risk factors for coronary artery disease, and the patient is relatively young, the discomfort in the precordial region may be triggered by cardiac neurosis. If necessary, a psychological assessment scale can be done, combined with psychological relief treatment, and medications such as Shuhelian and Xinyue capsules can be taken to improve the discomfort in the precordial area. There are also patients with chest pain, which may be caused by herpes zoster or costochondritis.
