If angina occurs, because of the intensity of the pain and its severity, it may affect the gastrointestinal tract as well as the digestive tract and produce a series of symptoms, such as nausea and vomiting, profuse sweating. Once this happens, nitroglycerin and musk heart pills should be given sublingually immediately, and a family member or friend should call 120 for emergency services instead. After going to the hospital, the patient’s vital status should be monitored with continuous oxygen inhalation and continuous cardiac monitoring. In addition, coronary-dilating drugs such as isosorbide mononitrate tablets and anticoagulant drugs are given for treatment. After stabilization, a coronary angiogram is performed to determine the degree of luminal stenosis and an electrocardiogram is performed to determine the degree of angina and to evaluate the next treatment plan.
