Chest pain after staying up late is most often an acute heart disease, such as angina pectoris or acute myocardial infarction, both of which are relatively acute heart diseases. If not dealt with in time, the patient will easily lead to malignant arrhythmia, or even cardiac arrest and death. Generally, in addition to chest pain, patients will also be accompanied by chest tightness, palpitations or dizziness, pallor, cold sweat and other symptoms, and the feeling of chest pain is usually dominated by the feeling of pressure. To confirm the diagnosis, it is usually necessary to go to the hospital immediately to check the electrocardiogram and blood troponin, which can basically confirm the diagnosis. If the diagnosis can be confirmed, it must be treated immediately, acute myocardial infarction may have to be immediately given thrombolytic therapy or vascular intervention methods to treat.
