Gas chest tightness and chest pain can be relieved by sublingual nitroglycerin or quick-acting heart-saving pills. Angina pectoris and other coronary artery lesions are caused by coronary ischemia, often aggravated after exertion or emotional excitement (such as anger). For chest tightness and chest pain caused by anger, anger is only the trigger, the essence of the coronary artery ischemic lesions. On the one hand, we need to adjust the emotion, reduce the occurrence of anger, quarrel and other situations; on the other hand, we should be equipped with daily nitroglycerin or fast-acting heart pills, which can quickly relieve myocardial ischemia and reduce the occurrence of adverse cardiac events. If there is persistent chest tightness and chest pain or sublingual nitroglycerin pain is not relieved, it is necessary to go to a regular hospital at the first time, through the electrocardiogram, coronary angiography, etc. to clarify whether there is myocardial infarction, and to treat it as soon as possible.
