If patients currently have chest tightness and chest pain, they can go to cardiovascular medicine, respiratory medicine, and psychiatric psychiatry, with specific analysis as follows: I. Cardiovascular medicine: Especially if elderly people have chest tightness and chest pain, most of them may be caused by coronary heart disease and angina pectoris, so it is very correct to go to cardiovascular medicine. Some people may have chest tightness and chest pain caused by microcirculatory dysfunction, pulmonary embolism, coronary artery myocardial bridge, such problems, so you can also go to cardiovascular medicine. Second, respiratory medicine: If chest tightness and chest pain are currently considered to be caused by a more serious lung infection, you need to see a respiratory medicine department. Third, psychiatric psychology: If eventually no abnormalities are found, but the patient himself is a group of people with anxiety disorder, there is always chest tightness and chest pain, this situation should be considered because of psychological factors leading to somatic symptoms. It is recommended that the patient see a psychiatric psychiatry department, because only when the anxiety and depression are improved, the heart discomfort will really improve.
