Why does exercise cause sudden death, and what are the causes of sudden death?

Death due to excessive exercise. Sudden exercise-induced death is defined as non-traumatic death that occurs within 6 hours of the onset of symptoms during or immediately after exercise. In fact, it is not only caused by excessive exercise that causes sudden death due to exercise, but also because there are many potential causes of sudden death.

Sudden death is mostly caused by cardiac causes, and the most direct cause of sudden cardiac death is cardiac arrest, and the diseases that lead to cardiac arrest mainly include coronary heart disease, myocardial infarction, cardiomyopathy, etc., and central myocardial infarction is the most important cause of cardiac arrest or sudden cardiac death.

Sudden death can happen at any time, anywhere, and can happen to anyone. If a patient dies suddenly, the heart stops beating for more than 4-6 minutes, and the brain tissue is permanently damaged, and after 10 minutes, the brain will die! It is impossible for an ambulance to reach the patient within a few minutes, so it is necessary to learn a little first aid knowledge, which may save the life of a family member or someone else at a critical moment.

The first 4 minutes after the occurrence of sudden death is the first time for rescue. The earlier the rescue starts, the higher the success rate and fewer sequelae and complications.

Because they are busy with work or busy with life, many people lack exercise, if this type of person runs a marathon, it is easy to lead to accidents, so we must insist on exercising in life, even if it is 20 minutes of exercise every day, it will have a great effect, and exercise will make a person's physique more and more healthy. When you feel your heart beating fast and slow (arrhythmia) during a run, start adjusting your breathing and slow down slowly, so don't stop running abruptly. If your body temperature drops suddenly while running, you must stop and quickly replenish food, hot water, and clothing to keep warm.

During running, if you have chest tightness, wheezing, dizziness, etc., it is even more dangerous, and you must slow down to replenish energy and avoid falling. If symptoms are severe, seek help immediately.

In fact, in real life, the probability of sudden death from exercise is very small, rather than worrying about the sky, it is better to want to open some and move boldly. If you quit eating due to choking, then in the long run, the probability of death due to inactivity is staggering, and it is very effective in reducing life expectancy.

Sudden death is mostly caused by cardiac causes, and the most direct cause of sudden cardiac death is cardiac arrest. Diseases that cause cardiac arrest mainly include coronary heart disease, myocardial infarction and cardiomyopathy, and central myocardial infarction is the most important cause of cardiac arrest or sudden cardiac death.

Strenuous exercise leads to sudden death of patients, in fact, there is a very important precondition, the patient may have underlying cardiovascular disease, but exercise promotes the occurrence and development of this event, inducing sudden death of patients. The probability of sudden death in the healthiest people is very, very low, but increases in the presence of cardiovascular disease. What diseases cause sudden death during exercise.

Clause. 1. Malignant arrhythmia, which is one of the causes of sudden death when patients make an appointment for exercise, malignant arrhythmia mainly refers to tachycardia. When malignant arrhythmias occur, the heart loses its ability to pump blood, and at this time, the whole body is in a state of ischemia, and the most sensitive to these is sudden death of brain patients. The second reason is various types of cardiomyopathy, especially dilated cardiomyopathy and obstructive hypertrophic cardiomyopathy, which have degeneration of myocardial tissue, which often puts a serious burden on the heart during strenuous exercise, and also induces sudden death.

Exercise excites people and makes their hearts beat faster.

Causes of sudden death: First, too strenuous exercise can speed up the heart and lead to sudden death.

Second, dyspnea, resulting in people who cannot breathe and sudden death.

1 The vast majority of sudden motor deaths are sudden cardiac and sudden cerebral deaths, and the former are the majority. Studies at home and abroad generally believe that cardiogenic diseases such as coronary atherosclerotic heart disease, hypertrophic cardiomyopathy, and myocarditis are the first causes of sudden sports death. In addition, cerebrovascular malformations, aneurysms and hypertension are also risk factors for sudden motor death.

Among them, the incidence of young people is mostly related to congenital cardiovascular abnormalities, while the elderly are mostly coronary heart disease and cerebrovascular accidents.

2. Exercising in disregard of various signals sent by the body and insisting on exercising is the most important subjective cause of sudden death in exercise. Sudden death from exercise, although sudden, is not without any warning signs. If you think this is a normal reaction during exercise, and ignore it and continue to exercise, it is easy to "practice" problems.

In addition, if you don't exercise for a long time, and suddenly exercise a lot on a whim one day, accidents are more likely to occur.

3. If you still do a lot of practice when you have a cold and fever, it is easy to have an accident. Colds have a pathological cycle, and it is best to drink more water and rest more when suffering from a cold, so that the body can produce natural immunity. When a person has a cold and fever, the frequency of blood supply and oxygen supply to the heart increases, resulting in an increase in the heart rate, and if you exercise again, it will inevitably increase the burden on the heart, and in severe cases, it will also cause myocarditis.

Once you have myocarditis, it is difficult to recover and can also impairing heart function.

4. In summer, the weather is hot, the blood vessels of the whole body are dilated, the blood flow is accelerated, and the heart has to increase the pumping volume and speed up the pumping speed in order to keep up with the pace of metabolism, which is overloaded for the heart and has the risk of inducing sudden cardiac death. Especially in the hot weather, high humidity, and no wind, it is most likely to have accidents.

In recent years, with the improvement of health awareness, more and more people have devoted themselves to sports, running is a simple and low-cost exercise, many people are keen on running, but the event of sudden death due to exercise in running also occurs frequently.

What is sudden death due to exercise

Sudden exercise death refers to accidental death during exercise or within 24 years after exercise, and the current ** of sudden exercise death is mainly: sudden cardiac death, accounting for 80%; Sudden cerebral death, accounting for 6% to 17%.

In the study, it was found that sudden cardiac death in young people is mainly due to hypertrophic cardiomyopathy, viral myocarditis, coronary artery malformations, Marfan syndrome, heart valves, or other diseases of the myocardial conduction system, but almost all people over the age of 40 are due to coronary atherosclerosis. The main causes of sudden brain-borne death are cerebrovascular malformations, aneurysms or hypertension, and arteriosclerosis. In addition, adrenal insufficiency, heat stroke during exercise, and stimulant use are also common causes of sudden death.

It can be seen that the main cause of sudden death during exercise is personal physical factors, followed by exercise habits. Athletes should make an assessment of their physical condition before doing a certain exercise, and only by exercising scientifically can they avoid risks.

The following 7 types of people should pay special attention when exercising:

1. Patients with a history of heart disease;

2. Patients with high blood pressure or irregular heartbeat;

3. Diabetic patients;

4. Cold patients;

5. Those who are obese and partially accompanied by metabolic disorders;

6. People who have no exercise habits and poor physical fitness;

7. Children and the elderly.

Note that it is not that these 7 types of people cannot exercise, but that we should pay more attention to the way of exercise and the amount of exercise to prevent accidents.

Sudden exercise-induced death is a non-traumatic death that occurs within 6 hours of the onset of symptoms during or immediately after exercise. Sudden death due to exercise is not caused by a single factor of exercise, but by a combination of exercise and underlying heart disease. Hypertrophic cardiomyopathy, congenital coronary artery malformation, is the main cause of sudden motor death, aortic rupture, aortic stenosis, mitral valve prolapse, pre-excitation syndrome, coronary heart disease, etc., may also lead to sudden motor death.

Sudden death can occur because the cerebral blood supply is insufficient or because the blood vessels are ruptured during exercise.

Sudden death from exercise is caused by a variety of reasons such as excessive pressure on the heart, malignant arrhythmia, and myocardial hypoxia.
