Introduction: Over the years, about the sudden death of young people in the reports are common, people in the sigh of life is fragile at the same time, but also in the reflection on why the urban white-collar sudden death is high. First, about sudden death you must know 1. China every minute 3 people die of sudden cardiac death According to statistics, China’s annual total number of sudden cardiac death up to more than 500,000 people, an average of 3 people per minute due to cardiac causes in the onset of death within an hour, and the success rate of resuscitation is less than 1%. 2. Sudden death is more and more likely to appear in the young people 3. fatigue easily triggered by chronic fatigue syndrome, the human body manifests itself in the body metabolic disorders, dysfunction of the nervous system regulation, immunity decline, and in severe cases, may even die suddenly. Second, easy to sudden death crowd 1. depression: depression and anxiety accelerate the formation of cardiovascular disease, cardiovascular disease, especially myocardial infarction is an independent threat factor. Cardiovascular disease accompanied by anxiety and depression, an important factor in sudden death. 2. Snoring: snoring is a sign of sleep apnea syndrome, if the time of “sleep apnea” is more than 120 seconds at a time, it is likely that sudden death in sleep. 3. Overexertion: often stay up late will make the sympathetic and parasympathetic nerves in a dysfunctional state; eating, rest and relaxation irregularities will cause low sugar and low potassium, electrolyte disorders, resulting in arrhythmia, which is an important cause of sudden cardiac death. 4. Stay up all night: long-term stay up all night induced arrhythmia, premature heartbeat and suddenly fainted, if you do not get timely first aid, easy to sudden death. In addition, staying up late for a long time will form blood clots and block blood vessels. 5. Stressful life: it will lead to hypertension, coronary heart disease, and will increase the risk of arrhythmia, vascular spasm, and even induce sudden death. 6. Obesity: cardiovascular disease loves fat people. Obese people almost all the cardiovascular disease risk factors account for all. And fat people are prone to congestive heart failure, combined with coronary heart disease is prone to myocardial infarction and sudden death. 7. Sitting in front of the computer for a long time: long-term Internet belongs to the static action, blood viscosity is higher, the lower extremities may form deep vein thrombosis, movement of thrombus dislodgement, may cause pulmonary infarction, may lead to serious sudden death. 8. Smoking and drinking: the risk of myocardial infarction in people who smoke is three times that of normal people. What exactly can make the heart rate faster, blood pressure rises, is to pull the trigger on a heart attack, long-term alcohol consumption can also lead to heart failure and other diseases. Third, there are signs before the onset of sudden death Signs 1, pain In comparison, the pain response is the onset of sudden death signs, the most easily perceived signals. When you feel intense, tight, crushing pain in the chest, and feel breathless, we must be vigilant. Sign 2: Potential Causes In addition to pain, you should also be alert to potential causes that may lead to sudden death. For example, whether there is a history of thrombosis. For example, a patient with a fracture who has been restricted from exercise for a period of time is susceptible to venous thrombosis, which, if it falls out, can lead to pulmonary infarction. Sign 3, breath-holding, obvious cyanosis, purple lips, blood oxygen drop If the nature of the work is sedentary or standing for a long time, the blood circulation is not good, when the disease attack, in addition to pain, if there is breath-holding, obvious cyanosis, purple lips, blood oxygen drop, etc., we should be highly suspicious of the possibility of pulmonary embolism. Signs 4, severe blood pressure rise For patients with aortic dissection, the onset of signs is severe pain, and pain will be accompanied by severe blood pressure rise. Sign 5: Chest pain Coronary heart disease has the highest rate of sudden death. Typical coronary heart disease performance is chest pain, usually occurring in the sternum behind, the whole border is not very clear, it will be appropriate to the area of a little bit larger (with the palm of the hand area is almost the same), or can not say exactly where the pain, mainly the feeling of boring pain. And the sting of a needle or “press the pain” feeling is often not related to the heart. Fourth, we must learn the first aid measures Fifth, the prevention of sudden death, from the start of life Sudden death seems unpreventable, but from the habits, emotions, make adjustments to cultivate a good lifestyle, maintain good health, it is possible to reduce the incidence of sudden death. 1. Maintain 6 hours of sleep every day; 2. Eat a light, low-fat diet; 3. Quit smoking and drinking; 4. Exercise in moderation to improve health and develop cardiorespiratory fitness; 5. Maintain a good mindset to reduce stress and avoid anxiety and depression; 6. Pay attention to cultivating personal hobbies and interests, so that when the pressure is on, it can be counteracted by hobbies and interests.
