Uncle Huang is 66 years old. After retirement, he often dances under the community. Now it is the leader in their team. Every morning and evening, they will dance for one hour to exercise.
One morning, he danced with the uncle and aunts downstairs as usual, but after a few minutes of movement, he felt uncomfortable with chest tightness. He felt that his chest was pressed pressureBig big stones.At first I thought it was caused by no rest. I thought about going to the side to rest.
The dancers quickly called the 120 emergency call. The people around them had no relevant first aid knowledge, and they could only be anxious.After arriving at 120, I found that Uncle Huang had a cardiac arrest and immediately performed cardiopulmonary resuscitation for him.However, if the heart stops for too long, whether Rao has been fully rescued, or fails to restore life.
In various types of emergencies, suddenly death follows suicide and accidents, becoming the third major factor .
In the face of such a tragedy, we cant help asking: Sudden death, can it really be helpless?
However, the research published in "China First Aid Medicine" seems to unveil the corner of the mysterious veil for us.
1. It is exposed to cold weather for a long time, and sudden heart death will "lag behind"?
A research in the magazine of "Liu Ye Dao". Researchers conducted 74 million deaths in 384 regions in 13 countries from 1980 to 2010 from 1980 to 2010.After analysis, it was found that 7.71%caused by high temperature and low temperature weather.Among them, Cold weather is the main cause of death , reaching 7.29%to account for less than 1%of high temperature.
Studies point out that cold weather will bring a large test to the cardiovascular and respiratory system. On the one hand, cold can affect blood pressure, cause blood vessel contraction, increase blood viscosity, and inflammatory response, which indirectly leads to cardiovascular stress; on the other hand, cold can induce bronchial contraction, mucus cilium defense, and other immune response, and then thenIt is easy to cause local inflammation and respiratory tract infection.
The sub -publication of the "American Medical Association" also published a research. Studies have stated that among many weather parameters, the cold, wind and sunshine time are shortened.It will increase the risk of myocardial infarction, which has the greatest impact of temperature.Specifically, temperature & gt; 0 ° C higher incidence, the probability of 3 ~ 4 ° C will begin to decrease, and the temperature will decrease by 2.8%at a risk of 7.4 ° C.
The reason why this phenomenon is because people will have a physiological reaction such as accelerated heart rate, rising blood pressure, and more blood pressure pumping blood in the cold environment.These factors are prone to coagulation.It will not have a big impact for ordinary people, but for middle -aged and elderly people who suffer from cardiovascular diseases themselves, they are likely to induce acute myocardial infarction.
Now the weather is getting colder, so be sure to keep warm, especially the elderly with poor cardiovascular function in itselfIntersection
2. The law of sudden death is found. You must pay attention to these four points!
In a study in "China First Aid Medicine", a study of 5516 sudden dead bodies found out that there are these things in common.
1. Sudden heart -derived death occupies "half of the country"
Sudden heartogenic death accounted for 57.76%, of which coronary heart disease sudden death was the most common.Data in the "China Cardiovascular Health and Disease Report" shows that about 550,000 people die from sudden heart -derived every year in my country , which is equivalent to falling down every minute.
The cardiac arrest occurs, and the best golden treatment time is only 4 minutes .An irreversible injury occurs.Each delay for 1 minute, the survival rate will decrease significantly, and there is almost no possibility of saving after 10 minutes.
2. Hypertension is the "invisible pusher" of sudden death
Patients with hypertension at the age of 30The risk of sudden cardiac death will increase by 30%compared to ordinary people. Blood pressure will increase by 20%by 20%at 20/10 mmHg, and the risk will be further increased by 20%.In particular, some patients with hypertension with diabetes will lead to further increased risk of sudden death.
3. Emotional excitement and exhaustion are the "number one killer"
Studies pointed out that about half of the sudden deaths had emotional and overworked problems during their lifetime.In a state of emotional excitement, the production of bone marrow white blood cells will increase, which will easily cause coronary inflammation , resulting in increasing plaque damage. In this case, the probability of cardiovascular emergencies will increase significantly.Tired of labor will make the burden on the heart, it is easy to induce blood pressure to rise and increase the risk of sudden death.
4. Middle -aged group "Sudden Disaster Area"
The highest incidence age of sudden cardiac deathDuan is 30 ~ 63 years old . Compared with the elderly, young people are more likely to cause sudden death when there is myocardial infarction.Because the heart of young people has not yet formed a compensation protection mechanism, it is prone to malignant arrhythmia when acute myocardial infarction occurs, and it is easy to instantly lose consciousness and cause sudden death.
Three, the chest "噔" is related to sudden death?Be wary of 3 signals!
I believe that many people have experienced this experience in life, and the heart feels suddenly a little bit stunned. This is very scared. Will it be a precursor to sudden death?
In fact, the tingling sensation and pain in the heart area are not fixed for a short time, and it can be recovered in a few seconds.Cardinal diseases such as angina pectoris and coronary heart disease are also small.This symptom is related to bad postures and habits, so you dont need to worry too much.
The occurrence of sudden death is not silent. When these symptoms appear in the body, be alert to medical treatment in time.
① There are squeezing feelings on the chest
Sudden abnormal squeezing pain occurs on the chest, and it may beAccompanied by dying and fear, this symptom may suddenly appear or frequently occur, and the symptoms last for a long time.
② Difficulty of breathing
The blood function of the heart on the eve of the sudden death will decrease, causing some blood to accumulate in the lungsThere are obvious symptoms of breathing difficulties in the body of the body.
③ Blood pressure abnormalities or even syncope
There is no reason, low blood pressure, cold sweat, etc.Symptoms, some patients even faint.
Winter is a great test for the elderly with cardiovascular disease.Observe more physical performance and find abnormal medical treatment in time.
