The people know that heart disease is an urgent, critical and serious disease, and will die if not treated in time, but how urgent and critical it is is not very clear, and what to do after the onset of the disease is not understood, so we often hear around us that so-and-so died suddenly of heart disease, so-and-so died young, and so on. We all know that in the absence of blood supply to the heart muscle, the cells will soon die. It is medically believed that within 3 hours after the occurrence of acute myocardial infarction is the “golden time”, if the patient can be rescued in time, the incidence of adverse events such as death and heart failure can be reduced to a minimum. If you go to the hospital immediately after symptoms appear, most of the myocardium can survive within 3 hours by using anticoagulant and thrombolytic drugs and opening blood vessels; after 6 hours, only about 30-40% of the myocardium can be saved; after 12 hours or more, the myocardium is basically necrotic, and opening blood vessels is basically ineffective. Therefore, after the occurrence of acute myocardial infarction, every minute is precious, and every second is needed to save the myocardium, time is myocardium, and time is life. If there is persistent chest pain, chest tightness, pressure or choking sensation in the precordial area, with or without radiating pain in the left shoulder and back, and cold sweat, then it is advisable to do the following things: 1. Rest immediately Whether you are in sports, meetings, work, eating, stop immediately, find a place to lie down, rest quietly and motionlessly, and at the same time tell the surrounding family, colleagues or others, etc. that you are uncomfortable and ask them to Take care of you. If you usually have the habit of carrying heart pills or nitroglycerin with you, when the above chest pain occurs, besides resting immediately, take the first aid medicine immediately, if it cannot be relieved, you can repeat it 2-3 times after 5-10 minutes. 3, call 120 emergency phone If the above chest pain continues not to relieve, or chest pain is severe and unbearable, you should call 120 emergency phone and go to the hospital emergency treatment, many hospitals now have a green channel, patients suspected of acute myocardial infarction can be treated immediately, to win valuable time for the patient. If you live in a mega-city where the traffic is terrible and it takes longer for an ambulance to come over, and there is a hospital not far from you, it is recommended to go to the nearest hospital with the escort of your family or colleagues to have an electrocardiogram and a blood test for cardiac enzymes first, so that once the diagnosis is confirmed, you can prepare for the next step of treatment. 4, drug thrombolysis and emergency revascularization (emergency stent placement) A large number of clinical evidence at home and abroad, stent placement is significantly better than drug treatment, the vascular opening rate of more than 95%, significantly reduce mortality, but the surgery needs to be carried out in a timely manner, in the clinic we often see the patient was sent to the hospital early, but the family hesitant to discuss whether to do surgery, delayed to sign, watching the time minute by minute In the end, the patient’s heart muscle is irreversibly necrotic, which is a great pity. With the progress of technology, mobile medical and wearable devices will be used more often in the early diagnosis of diseases, and ECG will be recorded at any time when chest pain occurs and sent to the doctor’s work platform immediately, so that accurate and individualized guidance and treatment can be given in the shortest time, which is the future direction of heart disease development.
