There are many times when the location of angina pain is not necessarily in the heart. Often angina pain is widespread or in the thoracic part of the body, so it is difficult to determine whether it is angina or stomach pain. To determine whether it is angina or stomach pain, you have to judge it based on several aspects such as the time of pain, the place of pain, and the duration of pain. Let’s take a look at it together. 1, the time of pain angina better common triggering factors are exertion, emotional excitement, too full, constipation, cold, smoking, alcohol, etc., in addition to tachycardia or bradycardia, high or low blood pressure, shock, etc. can also be triggered. However, the pain usually appears at the time of activity, not after exertion, and some patients have fixed occurrence in the middle of the night or early morning, lasting for several minutes or more than ten minutes, which can be relieved by rest or medication; while most of the stomach pain does not have a fixed time, and often occurs easily before or after meals. 2, the place of pain The site of angina is wide and variable, the typical site is after the middle of the chest, the pain is not very limited in scope, about the size of a fist or palm, it can involve the precordial area or behind the sternum, sometimes it can radiate to the teeth, left shoulder, left arm, throat or upper abdomen. Stomach pain is usually in the upper abdomen. 3, the way the pain About 60% of people with angina have symptoms of crush-like or crunch-like pain, often accompanied by anxiety or a sense of near-death fear. Some patients also describe the pain as burning-like or dull pain, but rarely describe it as pinprick-like or knife-like pain. If the pain is tossing and turning, tossing and turning is generally not angina pectoris. Duration Angina pectoris is usually paroxysmal, lasting 3-5 minutes and gradually disappearing, usually not more than 15 minutes or half an hour. Persistent pain for more than a few hours or days, or pain lasting only a few seconds is generally not angina pectoris. The duration of stomach pain depends on each person’s situation and condition, and the length of time is not fixed. 5, relief angina can be relieved after stopping the activities that trigger the symptoms, or sublingual nitroglycerin can be relieved within 3 minutes. For stomach pain, the appropriate medication should be determined according to the patient’s symptoms. Since angina pectoris and stomach pain occur in similar locations, both in the upper abdomen, many middle-aged and elderly people are prone to mistaking heart disease for stomach disease and delaying a better treatment period. If middle-aged and elderly people suddenly have chest pain or epigastric pain, do not easily conclude that it is stomach pain, but should first consider the possibility of angina pectoris or myocardial infarction. If the pain is relieved after taking nitroglycerin or quick-acting heart pills under the tongue, most of them are heart disease and should go to the hospital for further examination and treatment as soon as possible.
