Sudden death is not uncommon, it does not depend on age and it is not far away!

Whenever we see news about "XX-year-old young people suddenly died" in social news, we can't help but ask: Why do sudden deaths happen to young people and even become "common"? While we regret the loss of life, do we also need to be vigilant about the occurrence of sudden death and reflect on unhealthy and irregular living habits?

Sudden death is not uncommon

Sudden death is a regret that comes unexpectedly, and it is also a disease that comes suddenly. It is defined as a patient who is usually healthy or seemingly healthy, who dies suddenly due to a natural disease in an unexpectedly short period of time. In medicine, sudden death is divided into sudden cardiac death and non-cardiac sudden death. Sudden cardiac death is also a type that is frequently reported . The cause of death of many celebrities is sudden cardiac death , which refers to natural death caused by various heart reasons . The onset is sudden and the progression is rapid . Death occurs within 1 hour after the onset of symptoms .

In addition to the sudden death cases that have attracted widespread attention in the news, there are also many people who pass away from sudden death in real life. Studies have shown that there are more than 500,000 sudden death patients in my country each year, of which more than 400,000 are sudden cardiac deaths. Among these people, about 80% occur at home, and 20% occur on the road or in public places. The highest incidence rate is among people over 40 years old, up to 70%, and adolescents account for about 30%. In comparison, sudden death is more common in men than in women, about four times higher than in women. Sudden death is not only read in the news, but a real phenomenon that happens in life and is not uncommon.

Sudden death , regardless of age

Data show that the vast majority of sudden deaths during exercise are related to cardiovascular problems . Generally speaking, the main cause of sudden death during exercise in people aged 35 to 40 is coronary heart disease. For young people under 35 years old, the most common causes of sudden death during exercise are hypertrophic cardiomyopathy and congenital coronary artery malformations, followed by myocarditis, arrhythmogenic right ventricular cardiomyopathy, mitral valve prolapse, coronary heart disease, aortic valve stenosis, dilated cardiomyopathy, arrhythmias caused by ion channel diseases, aortic dissection and other congenital heart diseases.

Unlike the elderly, whose sudden death is mostly caused by coronary heart disease, young people have fewer warning symptoms of sudden death, with only 29% of patients having prodromal symptoms such as chest tightness and discomfort. At the same time, the cause of sudden death is unclear, with only 14% of patients experiencing sudden death induced by exercise. The most common causes of sudden death among young people are fatal arrhythmias (31%), coronary artery disease (22%), and hypertrophic obstructive cardiomyopathy (14%). In recent years , due to increased work pressure and accelerated pace of life , sudden death has also become a threat to young people .

Sudden death is not far away

When young people stay up late, they often joke that if they don't sleep, they will die suddenly. It can be seen that the public recognizes that staying up late for a long time will increase the risk of death. In addition to congenital and acquired diseases, for young and middle-aged groups, unhealthy lifestyles and habits may become the predisposing factors of sudden death. Long-term lack of sleep is the bait of the god of death. The heart is one of the most important organs in the human body. Its vibration is the embodiment of life, but for the heart that works hard every day, it needs to rest at night. We all know that the ideal sleep time for people is 6.5-8 hours. Death and sleep time are in a U-shaped curve relationship. Too little or too much will increase the risk of death. Therefore, long-term lack of sleep will increase the risk of coronary heart disease and stroke , as well as the risk of sudden death .

Some people regard coffee as "life-extending coffee", which is unscientific. Although they feel energetic for a while, the excitement of the sympathetic nerves will increase the heart rate and increase the burden on the heart. Some people think that they can stay away from risks by catching up on sleep after staying up late. In fact, when the physiological rhythm is disrupted and the quality of sleep is not good, the risk of coronary heart disease will also increase. Among the cases of sudden death , there is also a category of staying up late and sitting still for a long time . The combination of the two will increase the risk of lower extremity venous thrombosis . If the thrombus breaks off and embolizes the pulmonary artery with the blood flow , it will also cause sudden death .

For urban office workers , excessive exercise is also a cause of sudden death . When people do exercise that exceeds their physical endurance, danger is slowly approaching. When people do strenuous exercise, the sympathetic nerves are extremely excited, the myocardial contractility is strengthened, the heart rate is accelerated, and the blood pressure is increased to meet physiological needs. However, after the electrophysiological activity of the heart is disturbed, fatal arrhythmias such as ventricular fibrillation are likely to occur, and sudden death will occur. This is why you need to warm up fully before starting exercise. In addition, you must remember to replenish water, energy and electrolytes in moderation during exercise to maintain the normal physiological functions of the body. At the same time, exercise within a reasonable exercise range, and do not be aggressive. Once symptoms such as pale face, cyanosis of lips, sweating, fainting, chest pain, chest tightness, chest pressure, dizziness, headache, and extreme fatigue appear, you should stop exercising immediately.

We all feel regret for every life that has passed away. In order to have fewer such regrets, we urgently need to pay attention to heart health. Some patients with sudden cardiac death will have prodromal symptoms, such as chest tightness, chest pain, and repeated syncope. Even without these symptoms, electrocardiograms, cardiac ultrasound and other examinations will have certain positive findings. Therefore, when symptoms such as repeated syncope , severe chest tightness , chest pain , and fatigue occur, you must seek medical attention in time and never take it lightly. In addition, as a preventive measure, physical examinations should also be put on the agenda to detect existing problems early and add a guarantee to your own health.
