Angina pectoris is a clinical syndrome caused by acute, temporary ischemia and hypoxia of the myocardium due to insufficient blood supply to the coronary arteries. It is characterized by paroxysmal anterior chest crushing pain, which may be accompanied by other symptoms. The pain is mainly located in the posterior sternum and may radiate to the precordial region and left upper extremity, often occurring during labor or emotional excitement, lasting several minutes and disappearing after rest or nitrate preparation. The disease is mostly seen in men, and most patients are over 40 years old. Exertion, emotional excitement, satiety, cold, rainy weather, acute circulatory failure, etc. are common triggers. However, many patients with atypical symptoms can be seen clinically, such as angina pectoris manifested as toothache, stomach pain, etc. Once the above symptoms appear, you should seek medical attention. Once the above symptoms appear, you should promptly consult the cardiovascular medicine department for a clear diagnosis and timely formal treatment. Myocardial infarction may occur if angina persists for 30 minutes and cannot be relieved. In addition, a small number of patients with acute myocardial infarction are asymptomatic or have atypical symptoms, especially the elderly. Such patients usually do not have chest pain, but have pain in the upper abdomen, throat or even teeth, or unexplained syncope or coma, etc. Whether or not the problem is cardiac, as long as the symptoms are severe and the pain persists without relief, they should seek prompt medical attention to clarify the cause. The risk of myocardial infarction has a lot to do with the time of patient resuscitation. The success rate of patients with myocardial infarction is very high if they are resuscitated in time. In recent years, with the diversification of myocardial infarction treatment methods, the risk has been reduced year by year, but the post-care treatment of myocardial infarction is also crucial to avoid secondary infarction after myocardial infarction is an important factor in reducing the mortality rate of patients. Acute myocardial infarction acute attack first aid need to pay attention to immediately stop all activities, bed rest, minimize agitation, keep the room quiet, so as not to stimulate the patient aggravate the condition. Immediately take one nitroglycerin or quick-acting heart pills
5-10 capsules. If the patient is found to have a weak pulse, cold extremities and indifferent expression, shock may occur, the patient’s head should be gently lowered and the feet elevated to increase the amount of blood returned to the heart; if the patient appears to be wheezing, spitting a lot of foamy sputum, as well as overly obese patients, the head-low-foot-high position is prohibited to avoid aggravating chest tightness, the patient can be given a semi-recumbent position to reduce the load on the heart, so that the patient can take nitroglycerin, cardiac pain, aspirin under the tongue The patient can be placed in a semi-prone position to reduce the load on the heart.
