If the patient has chest tightness at night while sleeping and the symptoms are relieved to a certain extent by sitting up, it is highly considered to be caused by heart failure, and the patient is advised to push furosemide quietly, and also pump sodium nitroprusside and neoreactive drugs intravenously at 10 pm. If it is caused by coronary angina, sublingual administration of compound salvia drops and heart pills during the onset of chest tightness, and regular daily doses of metoprolol, aspirin, vancomycin, and isosorbide mononitrate will help prevent chest tightness at night. In addition, it may also be caused by the presence of cardiac neurosis, such as insomnia or difficulty in sleeping, combined with the use of drugs that have a calming effect on sleep, such as Sweet Dreams capsules, eszopiclone tablets, etc.
