In recent years, we have heard the news of the sudden death of many stars, Ma Ji, Xie Jin, Gao Xiumin, Hou Yaowen, Gu Yue, Chen Yifei ……, they all died suddenly because of heart disorders, these tragedies occurred, not only to the family and the public brought unexpected trauma, but also to everyone sounded the alarm. Sudden death: the most dangerous disease Sudden cardiac death is the most dangerous and traumatic part of the cardiovascular event chain, which is the sudden and unexpected death caused by various heart diseases. When sudden death occurs, the patient mainly shows loss of consciousness, convulsions, convulsions, cardiac arrest, cyanosis, dilated pupils, and loss of response to light. The number of sudden cardiac death patients in China is the highest in the world, with more than 500,000 cases each year, and the trend is increasing year by year. Experts pointed out that the mortality rate of sudden cardiac death is very high, once it occurs, the personnel present must immediately resuscitate in place, the patient has the hope of “coming back to life”. The implementation of cardiopulmonary resuscitation time is the key to saving lives, within 1 minute of the correct implementation of cardiopulmonary resuscitation first aid, resuscitation success rate is 88%; 4 minutes to save, the chance of success is 50%; 8 minutes to save the success rate is 15%; 9 minutes to save only 6% success rate; more than 10 minutes there is basically no chance, the chance of success is less than 1%. Coronary heart disease: the biggest “culprit” of sudden death Coronary heart disease is the main cause of sudden cardiac death, according to the United States Framingham study found that 80% of men and 42% of women. However, experts pointed out that sudden cardiac death and the severity of coronary artery disease is not proportional, some patients have serious coronary heart disease, but after active treatment, the collateral circulation has been established and run well, so they can live a peaceful life; some patients, although the degree of coronary atherosclerosis is not serious, but patients do not care about their own health status, no active defense, but because of some triggers will lead to sudden death. Among them, unstable angina, excessive strenuous or persistent physical work leading to overexertion, prolonged mental work, serious lack of sleep, strong stimulation of the surrounding environment, full meals or large amounts of alcohol, excessive mental tension, and excessive emotional excitement can cause sudden death due to the sudden deterioration of the condition of patients with coronary heart disease. Therefore, pay attention to their own condition, active defense, to avoid the above triggers, can effectively prevent sudden cardiac death. Active defense: do not give sudden death “opportunity” For the defense of sudden cardiac death, we should start from two aspects. On the one hand, for people at high risk of coronary heart disease, we should try to reduce or eliminate the risk factors of coronary heart disease to avoid the occurrence of coronary heart disease, such as keeping their blood pressure, blood sugar, lipid standards, controlling their weight within the normal range, quitting smoking completely, limiting the amount of alcohol consumption, strengthening sports and exercise, being cheerful and open-minded, maintaining a good mood, and having regular medical checkups to understand their physical condition and to achieve early detection and treatment of the disease. Early detection and early treatment. On the other hand, for patients with coronary heart disease, they should be actively treated, starting from drugs, diet, exercise and other aspects, to control the disease in a stable state. The coronary heart disease treatment drug Tongxinluo capsule, which is commonly used in the clinic in recent years, can remove elevated lipids and agglutinated platelets in the blood, reduce blood viscosity, reduce the deposition of these substances in the blood vessel wall and prevent the formation of atherosclerotic plaques; ablate and stabilize the atherosclerotic plaques already formed in the blood vessels, unblock the blocked coronary vessels, improve the blood supply to the heart and release the vascular spasm; effectively treat Coronary heart disease, prevent the development of the disease; also can protect the survival time of microvessels in the ischemic and hypoxic environment, maintain the structural integrity of microvessels, and can promote the myocardial ischemic necrosis area of the blood vessel neovascularization, for the myocardial cells to establish a new blood flow pathway, can effectively prevent the occurrence of cardiovascular accidents. Pay attention to the aura: do not let the tragedy happen Experts pointed out that although sudden cardiac death occurs suddenly, but many patients often have days or weeks or even months of prodromal symptoms before the occurrence of cardiac arrest. For example, angina, irregular heartbeat, dizziness, chest tightness, extreme fatigue and other non-specific symptoms of discomfort. Patients and their families should pay attention to these signs and symptoms, and pay great attention to these symptoms and seek medical attention in time for early prevention to prevent tragedy from occurring. In addition, there are several other situations to be alert to the occurrence of sudden cardiac death. First, the elderly appear unexplained fainting; second, frequent angina pectoris or severe angina pectoris after myocardial infarction, extensive infarct area or anterior wall infarction with heart failure, shock, severe arrhythmia patients prone to sudden death; third, 16% of patients with unstable angina pectoris will have sudden death; fourth, hypertension with left ventricular hypertrophy in patients with asymptomatic myocardial ischemia, should be alert to sudden cardiac death; fifth, elderly cardiac The recurrence rate of 30%-40% within one year for those who are successfully rescued from sudden death should be alerted to sudden death again. The correct first aid: let the patient “back to life” occurred sudden cardiac death, the patient beside the people in addition to timely call 120 for help, if also know the correct method of rescue, then the patient will have the hope of “back to life”. The correct first aid is cardiopulmonary resuscitation, and there are three basic steps: airway patency, artificial respiration, and artificial circulation. First, keep the patient’s airway open. Place the patient on a hard flat surface in a supine position, and the rescuer tilts the patient’s head back with both hands, holding the jaw joint to clear the oral foreign body and keep the patient’s airway open so that the loose tongue does not tilt back and block the airway during sudden death. Second, perform artificial respiration to maintain the patient’s respiratory function to ensure the aerobic metabolism of the major organs of the body, especially the brain, protect the function of the respiratory center, and prevent cerebral edema. The rescuer pinches the patient’s nostrils with one hand, inhales deeply and then blows the gas mouth-to-mouth into the patient’s mouth at a rate of 20 times per minute. Third, perform first aid of artificial circulation, which mainly includes 3 aspects of extra-thoracic cardiac compressions, direct current defibrillation, and intravenous or intra-cardiac drug injection, and family members perform out-of-hospital first aid for patients mainly with extra-thoracic cardiac compressions. The method of cardiac compressions should be correct, the rescuer overlaps the palms of both hands on the lower part of the patient’s sternum, the midpoint of the line between the two nipples, keeping the main pressure on the sternum to reduce the occurrence of rib fractures, the arms are straight when pressing, the force should be smooth and even, the pressure should be large enough to depress the sternum 3~5 cm, then suddenly relax, press at a rate of 60~70 times/min, continuous compressions without interruption. The patient’s carotid artery or femoral artery can be touched after effective compressions, and the patient’s dilated pupils can be seen to begin to narrow. Among them, artificial respiration and chest cardiac compressions can be performed several times in a 2/30 ratio cycle, and the patient’s response should be observed.
