Recently, major websites reprinted a news story that a 25-year-old female anchor died of an acute heart attack at home. Many people were shocked after reading it. It was fine during the day, how come it suddenly died at night! For the occurrence of such sudden death, a number of people have asked me for advice on how early detection, prevention and treatment can be achieved. In 1979, the International Society of Cardiology, the American Heart Association and the World Health Organization defined sudden death in 1970 as an unexpected death that occurs immediately after the onset of acute symptoms or within 24 hours. Later, the World Health Organization defined sudden death as death within 6 hours after the onset of symptoms. Most scholars now prefer to limit the time of sudden death to within 1 hour of onset. It is characterized by a sudden, unexpected, natural or nonviolent death. There are many causes of sudden death, cardiac and non-cardiac, such as myocardial infarction, cerebral hemorrhage, acute myocarditis, obstructive hypertrophic cardiomyopathy, pulmonary embolism, acute necrotizing pancreatitis, asthma, allergy, sudden death syndrome, staphylococcal fulminant purpura, drugs, and so on. But the most common is the cardiovascular system diseases, of which coronary heart disease is a major culprit of sudden death, coronary myocardial infarction (MI) is a disease caused by coronary atherosclerosis caused by thrombosis, blockage of the branches of the coronary arteries, so that part of the heart muscle lost blood supply and necrosis. More common forms of death are arrhythmias, and more than 80% of deaths are arrhythmias, in which the heart beats more disorderly. More than 80% of these deaths are due to arrhythmias, such as ventricular fibrillation. The main symptoms are: chest tightness, chest pain, cold sweat, palpitations, shortness of breath, weak pulse in severe cases, reduced blood pressure and even coma, and death if not treated in time. At present, the trend of coronary heart disease myocardial infarction patients are getting younger and younger, which has a lot to do with modern people’s poor living habits, eating habits, increased mental stress, 120 emergency patients, many of which occur after drinking, mahjong tables, bathrooms, Internet cafes and other places. What should I do if I have a heart attack? Patients who have been diagnosed with coronary heart disease, serious cases need to do stent placement or coronary artery bypass surgery, light cases need to follow the doctor’s requirements for regular medication, for this part of the patient is recommended to always have nitroglycerin, quick-acting heart pills, etc. in your pocket, once the chest pain, immediately sublingual such drugs, family members open doors and windows, keep ventilation, so that patients can suck enough oxygen, the situation is serious need to promptly call the emergency number In serious cases, call the emergency services. If cardiac arrest occurs, CPR (cardiopulmonary resuscitation) needs to be started immediately before the arrival of an ambulance, and the importance of CPR has been confirmed. How do untrained people who encounter this situation perform CPR? According to the 2010 American Heart Association CPR and cardiovascular emergency guidelines, compared to the old CPR, the most important thing is proposed: “It is strongly recommended that ordinary rescuers do only chest compressions CPR, weaken the role of artificial respiration, the ordinary witness requirements for ABC changed to CAB that is, chest compressions, open airway and artificial respiration “CAB means “C chest compressions → A open airway → B artificial respiration”, which is the order of first aid, in short, is to determine the patient’s cardiac arrest, the first external chest compressions, and then open the airway. For those who are not trained in the steps of artificial respiration, they can just do chest compressions, which can also greatly improve the survival rate of patients. Specific operations: 1, determine whether the heart is in cardiac arrest: generally feel the carotid artery, at the level of the laryngeal node, on the inner side of the muscle, under normal circumstances can feel the arterial pulsation. 2, external chest compressions: the location of compressions is the middle of the line between the two nipples, the frequency of compressions is more than 100 times / min, the depth of compressions is more than 5cm; 3, open the airway: let the patient lie flat, press the forehead, drag the chin, open the mouth to remove the dirt in the mouth to ensure a smooth airway; 4, artificial respiration: pinch the patient’s nostrils, blow into the mouth until the sternum is lifted, the ratio of blowing and compressions is 2:30. For the heart attack Preventive measures, mainly regular medical checkups, once the problem is detected to timely treatment, especially hypertension, hyperlipidemia, diabetes (commonly known as three high), more timely treatment and control; in addition, it is important to develop good habits, standardized work and rest time, healthy diet, try to avoid overtime and stay up late, quit smoking and alcohol, etc..
