What are the causes of sudden death? What are the signs before sudden death
4hw.org: Although the material life of modern people is more and more rich, the pressure of life is also growing. What's behind the sacrifice is health or even life. This year, the number of people who die suddenly is increasing year by year. Although there are many reasons for sudden death, the root cause is still that. Next let's see what are the causes of sudden death and what are the signs before it?
Sudden death refers to the unexpected sudden death caused by nature. According to the World Health Organization, death within 6 hours after the onset of the disease is regarded as sudden death. All kinds of heart disease can lead to sudden death, and more than half of the sudden death of heart disease is caused by coronary heart disease.
The experts believe that the sudden death of a person shows that his illness has reached a certain level. If it is only a matter of great joy and great sorrow in life, or a bad weather, there is no serious pathological basis and life-threatening.
Sudden death can be divided into the following categories:
1. Sudden cardiac death
Sudden cardiac death is a kind of natural death caused by various cardiac causes, which is preceded by sudden loss of consciousness within one hour after the onset of acute symptoms. The most likely cause of sudden cardiac death is cardiovascular dysfunction, which makes the brain blood supply suddenly stop and lose consciousness, and finally leads to biological death. This kind of sudden death is the most common, most often occurs within 1 hour after the onset of the disease, and some even only a few minutes, mainly related to serious arrhythmias. Coronary heart disease is the most common. Some people can have no angina and other heart symptoms, coronary heart disease is hidden, sudden death is the first manifestation. Many so-called 'healthy' sudden death, that is the case. Hypertension affects the heart and causes left ventricular hypertrophy, which is also prone to sudden death. In addition, smoking, obesity, diabetes and lifestyle have an inseparable relationship with sudden death. Research shows that smoking increases the risk of SCD by 2-3 times, which is one of the few factors that lead to the proportional increase of the risk of sudden death of coronary heart disease. Obesity is the second factor that leads to the proportional increase of the risk of sudden death of coronary heart disease. People who are not used to exercise are also more likely to die of sudden death People who exercise are tall.
2. Sudden stroke death
In general, sudden death caused by stroke can last from several hours to one day. It is often seen in hemorrhagic apoplexy with more hemostasis, faster bleeding speed and involving important vital center. It can also be seen in the ischemic stroke involving the important parts of fanguoda. In patients with coronary heart disease, atrial fibrillation and left atrial thrombosis, sudden death occurs once thrombus falls off and enters cerebral circulation, causing multiple cerebral infarction. The patients with original stroke history and brain softening are also prone to sudden death after another stroke.

3. Sudden pulmonary death
Sudden death of pulmonary origin refers to the patients with chronic bronchitis, emphysema and bronchial asthma, who may die suddenly due to severe hypoxemia at night: respiratory acidosis, chronic bronchitis and emphysema patients, such as excessive use of antiasthmatic aerosol, may cause bronchospasm contraction, asphyxia and hypoxia, resulting in sudden death. The elderly who are bedridden for a long time can't cough and expel phlegm forcefully because of their weak body, which can cause phlegm thrombus to block the airway and aggravate the secondary pulmonary infection, leading to sudden death of pulmonary origin.
4. Sudden choking death
Sudden choking death refers to the poor chewing function of the elderly, insensitive swallowing reflex, and more sluggish response after drinking, so 'choking' often occurs in eating and drinking. Large food lumps can block the trachea and cause suffocation. This kind of death often happens suddenly. The patient cannot speak. He often points to his throat, then his face turns purple, his eyes turn up, and he suddenly falls over.
The reason for the sudden death of the elderly due to choking is that they have teeth disease or missing teeth, poor chewing function, and are easy to swallow whole dates; secondly, the incidence of cerebrovascular disease in the elderly is high, the pharyngeal launching force is slow, and the swallowing action is not coordinated; thirdly, the alcoholic elderly are easy to lose control after drinking; fourthly, the esophageal stenosis of the elderly, so that the swallowing food is not smooth; Fifth, the elderly are unstable and prone to esophageal spasm due to stimulation. All of the above causes can easily lead to food infarction in the throat or esophagus, resulting in asphyxia. Choking is one of the causes of accidental death. According to foreign statistics, this kind of death is the sixth cause of sudden death. Scholars believe that the disease is on the rise in China, because the number of elderly people eating in restaurants is increasing and they are often misdiagnosed, which is not easy to attract the attention of the elderly and their relatives.
To prevent sudden death and pay attention to health, a comprehensive health examination should be carried out once a year to observe the changes of the original diseases and the occurrence of new diseases. For these congenital and acquired diseases, active treatment should be carried out to avoid emotional excitement, overwork and other inducements. When symptoms or discomfort appear, check and treat in the hospital as soon as possible.
Signs before sudden death
1. Recent or aggravated chest tightness.
If you suddenly have chest tightness after activity in the near future, rest for a period of time can relieve it, which indicates that you may have coronary heart disease. The sudden symptoms indicate that the atherosclerotic plaque in the coronary artery is not stable and may rupture at any time, leading to acute myocardial infarction. If there were occasional chest tightness before, the recent symptoms become more frequent and more serious, which also shows that the plaque which was stable before has small damage, and will develop into large damage at any time, leading to the occurrence of acute myocardial infarction. In this case, we should go to the hospital as soon as possible, and carry out medication or surgery.

2. panic.
Palpitation is often the subjective feeling of an increased heart rate. The irregular increase of heart rate is usually the result of tachyarrhythmia. Most of the arrhythmias are less dangerous and will not cause sudden death, but if it is frequent ventricular arrhythmias, there is a risk of developing into ventricular fibrillation. In addition, a lot of elderly people have panic caused by atrial fibrillation. If atrial fibrillation is accompanied by heart conduction disease, it is also easy to progress to ventricular fibrillation. Death occurs within minutes of the onset of VF. Therefore, frequent panic attacks should also be treated in time.
3. Slow heartbeat.
The beating of the heart is initiated by a specific pacemaker cell. If the function of the pacemaker cell becomes poor, the beating rate of the heart will slow down, and in serious cases, it will cause cardiac arrest. The function of pacemaker cells will gradually deteriorate with age. With the continuous improvement of life expectancy in China, the proportion of people over 80 years old is also increasing. The function of pacemaker cells in this part of population will gradually become worse, and the heart rate will gradually slow down. The activity of the elderly is usually small, and the slower heart rate can maintain normal life, so it is often ignored. The elderly should regularly monitor blood pressure and heart rate. If the heart rate is less than 50 times and the blood pressure becomes low, it is easy to have a long-term cardiac arrest, leading to sudden death.
4. syncope.
Syncope is an important precursor of sudden death. Most syncope is caused by the sudden slowing or stopping of the heart rate, which leads to the lack of blood supply to the brain. The common causes include sinoatrial node disease, atrioventricular block, vagal tension and so on. Syncope can recover itself after several seconds. If it can't, it will cause sudden death. Therefore, we should be very vigilant after the occurrence of unexplained syncope, find out the cause as soon as possible, and prevent the next syncope or even sudden death.
5. Unexplained fatigue.
Sudden death is not a patent for the elderly, but also for the young. Many young people work under pressure, often fatigue, which is a normal situation. However, in case of unexplained fatigue, fatigue, chest distress and edema, we should be alert to sudden death, which may be caused by myocarditis or cardiomyopathy. Myocarditis is more common in young people, usually seen in the cold 1-2 weeks later, fatigue, chest tightness, fatigue and other symptoms, easily lead to acute heart failure. In this case, heavy physical activity and bed rest are strictly prohibited. Cardiomyopathy is a genetic disease, which is difficult to detect in the early stage. When symptoms appear, irreversible changes of myocardial structure, such as cardiac enlargement, cardiac hypertrophy and so on, are likely to cause sudden death. Therefore, when there is unexplained fatigue and chest distress, we should be highly alert to the occurrence of myocarditis and cardiomyopathy.

6. The eyes are black and numb.
Stroke is also an important cause of sudden death. In some cases of stroke, limb paralysis and high blood pressure will occur within a few minutes. In this case, patients can save lives if they see a doctor in time. But some stroke starts slowly, early only has the slight symptom, the patient does not care. Once progress is made, sudden death may occur, so more attention is needed. Especially in patients with hypertension, coronary heart disease or atrial fibrillation, the incidence of stroke is several times higher than that of the general population. If one side can not see things, one side limb numbness, fatigue, or walking instability, there is a sense of stepping on cotton, we should be alert to the occurrence of stroke, timely treatment. Early recognition can often achieve better results.
In order to find the above omens of sudden death, we need to be alert to physical discomfort at all times, react quickly when the situation occurs, and get medical treatment in time.
