Recently, another round of hot weather has ushered in all parts of China, which is "torture" for fragile heart and blood vessels! Under the influence of high temperature and high humidity, the blood vessels of the whole body dilate, the blood becomes thick, people will feel chest tightness and shortness of breath … sudden death is easy to happen!
Statistics show that in China, nearly 550,000 people die of sudden death every year! Sudden death is so terrible, are we really helpless? No, in fact, some time before sudden death, our bodies will send out many "distress signals". If we catch these signals, we may be able to save lives successfully! So, how can we recognize the "signal" of sudden death at a glance?
"Clues" before sudden death
one
Symptom 1: chest pain
Pain response is the most easily grasped and perceived signal among the symptoms of sudden death. When you feel severe, tight and crushing pain in your chest, and you feel suffocated, you should be vigilant.
The typical manifestation of coronary heart disease is chest pain, which usually occurs behind the sternum. More attention should be paid to this kind of situation.

Symptom 2: purple lips
When the disease breaks out, it is highly suspected that it may be pulmonary embolism if, in addition to pain, there are conditions such as breath holding, obvious cyanosis, purple lips and decreased blood oxygen.

Symptom 3: Unexplained toothache
Toothache is not necessarily a problem of oral cavity, but may also be related to myocardial infarction.
In clinic, toothache caused by heart disease is usually called "cardiogenic toothache", which is different from common toothache. Toothache caused by heart disease often shows severe pain, but the pain site is not very clear, and the symptoms will not be relieved after taking painkillers.

Symptom 4: Radiation pain in shoulder, neck and arm.
Today, my neck hurts, and the next day it changes to my chin, or it hurts today and it doesn’t hurt the next day. This is because of heart ischemia, which always reflects the pain signal through nerve transmission in the spinal cord segment with the same level. The nearby organs such as shoulders, neck, chin and arms are in this range, and they will feel pain.
What is the "culprit" of sudden death
The important cause of sudden death is ventricular fibrillation. The "ventricle" is mainly responsible for pumping blood for the heart, so once the ventricle vibrates abnormally, the important organs of the whole body will not be able to get oxygen. As long as ventricular fibrillation occurs for 10 minutes, the human body will face the possibility of brain death, which is also a sign of judging human death.
Because of the onset of ventricular fibrillation, expect the unexpected, we must know in advance which diseases are easy to induce such abnormal fibrillation:
one
Sudden death of the elderly: coronary heart disease
Coronary heart disease (CHD) is the first cause of sudden death in the elderly. In fact, it is the blockage of the coronary artery responsible for transporting nutrition in the heart, which leads to myocardial necrosis and thus induces ventricular fibrillation.
The root cause of blood vessel blockage is precisely because of the bad habits of greasy diet, smoking and drinking, staying up late and daily lack of exercise, which leads to the increase of blood pressure and blood lipid in the body, forming plaques in blood vessels and causing poor blood circulation.

Sudden death of young people: hypertrophic cardiomyopathy
Hypertrophic cardiomyopathy is often poorly understood by most people, but it is one of the most important causes of sudden death of adolescents during exercise! In fact, hypertrophic cardiomyopathy refers to a person’s heart muscle is too hypertrophy, once affected by external factors, it is easy to block the heart outlet, resulting in blood can not be discharged smoothly.
Sudden death first aid, golden 4 minutes
Many times, sudden cardiac death often happens at home and on the road. Before the arrival of professional medical staff, family members, neighbors and witnesses are the best "doctors" to save lives.
Specific methods of gold 4-minute first aid:
Step one:
Judging whether the patient has cardiac arrest, sudden loss of consciousness+respiratory arrest or sighing breathing can be considered as cardiac arrest.
Step two:
Call for help, call 120, call people around you for help, and help to find AED nearby.
Step 3:
Hands-free cardiopulmonary resuscitation: First, chest compressions are performed for 30 times, the frequency is 100 ~ 120 times/minute, and the compression depth is about 5cm; Then give mouth-to-mouth artificial respiration twice, blowing for more than 1 second each time, and it will be effective if you see chest fluctuation. Then continue to rescue according to the ratio of chest compression and artificial respiration of 30:2, and judge the resuscitation effect for 5 rounds (about 2 minutes). Until the resuscitation is successful or 120 emergency personnel arrive to take over the rescue.
note:
Once cardiopulmonary resuscitation starts, never stop, otherwise it will do more harm to patients. If the AED is obtained on site, it is necessary to use the AED to defibrillate the patient at the first time.
Four things to cool the heart and brain vessels.
one
Don’t push hard.
Don’t do "turning around" in life, especially those with carotid artery stenosis or plaque, so as to avoid accidents.
Avoid actions that require sudden exertion, such as playing badminton, basketball, getting up suddenly, etc. People with unstable blood pressure should be more careful.
2
The temperature difference is too big.
If the air conditioning temperature is relatively low and the temperature difference between indoor and outdoor is too large, it is easy to cause blood vessels to contract or expand sharply when entering or leaving the door, causing blood circulation disorder and inducing myocardial infarction or cerebral infarction.
three
Ensure drinking water quantity
In summer, you sweat a lot, and a lot of water in your body is evaporated. If you don’t replenish water in time at this time, your blood concentration will increase, your blood will become sticky, and you will easily have a stroke.
four
Eat lightly.
Hot weather will cause people’s appetite to drop, but it is best to stick to a light diet. Eating too much oil or too salty will increase blood lipids and blood pressure, which is not good for cardiovascular and cerebrovascular health.
