1. Recurrent gastrointestinal symptoms: Frequent diarrhea without gastrointestinal diseases may be caused by myocardial infarction and one of the signs of sudden death. When myocardial infarction occurs, there will be insufficient blood supply to the whole body, which will make the gastrointestinal tract unable to peristalsis and cause indigestion or diarrhea.
2. I often feel tired and tired inexplicably: some people get enough sleep and have not done strenuous exercise, but they are extremely tired. This shows that it may be a sign of myocardial infarction, so we should pay more attention to avoid sudden death.
3. Chest tightness: When severe contraction and squeezing pain occur frequently in the chest and you feel breathless, you should be vigilant. We should also pay attention to the aggravation of symptoms in those who have chest tightness. When you often feel chest tightness after exercise, you will feel relieved after rest, which may be coronary heart disease; Chest tightness often increases suddenly, which may be caused by plaque accumulation in cardiovascular system. Beware of plaque rupture leading to myocardial infarction and sudden death.
4. Unexplained pain: shoulder, neck, chin, throat and arm pain, which is an early warning signal of myocardial infarction and ischemia, because when the information of myocardial ischemia pain reaches the central nervous system of the brain, the pain information will be reflected in these parts simultaneously, so be sure to seek medical treatment as soon as possible!
5. Frequent palpitation: Palpitation means that the rhythm of the heartbeat is like drumming, or the heartbeat is fast and slow. Occasionally palpitation is normal, but frequent palpitation may be heart fibrillation, which is caused by myocardial injury and hypoxia after myocardial infarction, and may lead to sudden death in a short time.
6. Black eyes and numbness of unilateral and bilateral limbs often appear: These phenomena represent that there may be problems with cerebral vessels, especially when patients with hypertension or coronary heart disease have this symptom, which may also induce myocardial infarction, all of which are the murderers who lead to sudden death.
7. Night sweats: If you don't do strenuous exercise, you will easily sweat for a long time, which is a warning sign of heart disease, decreased blood output and hyperactivity of sympathetic nerves. Especially before a heart attack, the scalp, neck, back, hands and feet will sweat a lot. You should stop your activities immediately, take your medicine immediately, and even call an ambulance to take you to the hospital urgently!
8. Frequent dizziness and fainting: If patients with heart disease often feel dizzy or even faint, it may be due to the slow heartbeat or sudden stop, which makes the blood supply to the brain insufficient. Most patients can wake up after fainting, but if they can't recover, it will easily lead to sudden death.
9. Shortness of breath and purple lips: If you are engaged in long-term standing or sedentary work, you should pay attention to people with poor blood circulation. When the pain is accompanied by suffocation, purple lips, cyanosis and decreased blood oxygen, we should be careful to prevent sudden death caused by pulmonary embolism.
10. Wake up with insomnia: If you don't get enough sleep for a long time, you will become weak mentally and physically, increasing the risk of sudden death from coronary heart disease. If you wake up in sleep, you will increase the risk of sudden death at night.
People with family history, cerebrovascular disease or several cardiovascular and cerebrovascular risk factors should pay special attention to the occurrence of the above symptoms. People without basic diseases should pay special attention to the above symptoms and seek medical advice in time.
