So have you ever worried, often stay up late to eat takeout, will one day also give the heart attack stared at it? What is a heart attack? Heart attack, that is, myocardial infarction. We compare the heart to a blood pump, which works day and night like a water pump to deliver blood to all parts of the body. The coronary arteries (blood vessels) in the heart are the wires that supply blood to the pump. Once the coronary arteries become occluded, it is like a problem with the wires, making the blood pump not work properly, which is the cause of heart attack. After the heart stops working, the whole person is not good, because there is no blood pressure, the blood does not flow, can not bring fresh oxygen to the body, the body’s cells begin to die, which is why people with heart attack at that moment will appear near death. Heart attack attack, easy to sudden death, identify the typical symptoms of heart attack is the key! 1, the patient’s left chest suddenly appeared oppressive, tight pain, lasting a long time, up to several hours or even longer, mostly occurring in the early morning. 2.Part of the patient will not appear pain, at the beginning of the manifestation of shock or acute heart failure. 3, some patients will have pain in the upper abdomen, often mistaken for gastric perforation, acute pancreatitis and other acute gastrointestinal diseases. 4, some patients will also spread to the upper jaw, neck, back and above, often mistaken for osteoarthralgia and did not pay attention, delayed treatment. 5.Other symptoms, such as nausea, vomiting, abdominal distension, palpitations and so on. When the chest pain occurs more than 24 hours can also appear low fever, body temperature of about 38 ℃. 6.Pale face, cold and clammy skin, agitation, low urine output, thin and fast pulse and other shock manifestations. 7, sudden difficulty in breathing, coughing, coughing pink or white foamy sputum. 8, the heart has stopped beating or intermittent, can be accompanied by dizziness, fatigue, fainting. Heart attack is no longer the patent of the elderly, the following are the high incidence of heart attack population: 1, “three high people” less exercise, overeating, eating too greasy, is our modern people’s common problems, resulting in high blood pressure, high cholesterol, diabetes, obesity and other groups of people, and these diseases are precisely the gas pedal of the infarction, which are basically decided to The problem of heart attack appears sooner or later. 2.Smoking people The negative consequences of smoking are very clear to everyone, not only will make the blood vessels harden, but also induce lung cancer. Heart attack is precisely due to long-term smoking caused by the hardening of the arteries, resulting in vascular occlusion, there are many clinical cases show that some patients with heart attack is precisely in the smoking attack. 3, often overtime crowd young and middle-aged people in the center of the infarction in some mental laborers mostly, for workaholics, and not a good thing. Some people work up a few days do not take a good rest, this kind of irregular, overworked life, very easy to lead to coronary artery spasm, thus inducing heart attack. 4, the crowd of excessive pressure fast-paced life, work pressure, piled on top of each other, often make people feel nervous, this time, the body will secrete a lot of adrenaline, resulting in blood vessel contraction, heartbeat acceleration, causing the onset of heart attack. Once a heart attack occurs, what should be done? Life-saving must be remembered! 1, if the people around the heart attack should immediately whistle and dial 120, can be in the emergency doctor’s phone under the guidance of the patient open rescue.

Uncollar your clothes, lie down or sit down to rest, and reduce your activities. If someone around you has a heart attack, don’t move the patient, your kindness may make the patient’s condition more serious. 3.If the patient has difficulty in whistling, he should do deep whistling slowly, and if there is a foreign object or denture in his mouth, he should take it out to keep the airway open. 4, heart attack, take nitroglycerin should be careful, if the patient’s blood pressure is low, or pulse beat weak, dizziness, sweat, etc., do not recommend blindly take nitroglycerin. The real heart attack is a very high mortality rate of disease, not the family which drugs or any other strange finger-tying bloodletting method can be relieved. Once the related symptoms appear, should be according to the above methods to save or self-help, is the safest solution.
