"I really didn't expect to die at such a young age."
The 26-year-old Xiaocong's family is very ordinary, his parents are ordinary working class, and he raises Xiaocong's 3 brothers and sisters with a meager salary. As the eldest, in order to reduce the burden on his parents as soon as possible, Xiao Cong did not continue his studies after graduating from high school and followed his relatives in the village to work.
In the years of work, Xiao Cong has been very "desperate", just to be able to settle down in the city. In addition to his daytime work, he also goes to work part-time to deliver food at night, and sleeps an average of less than 5 hours a day. In order to buy a house and a car, he has not complained.
This state lasted for several years, and recently Xiao Cong found himself always inexplicably dizzy and chest tight, which could be alleviated by resting for a while, so he did not take it seriously. Continuing the original rhythm of life, in the process of delivering takeaways one day, Xiao Cong suddenly "planted" down... He never woke up again.
Doctors in the emergency room said that there are not a few cases of sudden death of young people like Xiao Cong, most of them are due to long-term excessive fatigue caused by cardiac arrest, and many have stopped breathing when they are sent over, which is lamentable.
<h1 class="pgc-h-arrow-right" data-track="5" > First, the number of sudden deaths in China exceeds 500,000 every year, don't let stay up late to "die" the heart</h1>
Clinically, sudden death is divided into two types: cardiac and non-cardiac, the proportion of the two is about 75%: 25%, based on the data of 1.3 billion people in China, the number of sudden deaths caused by cardiac factors is about 544,000 per year.
Whether it is the cause of sudden cardiac death of both cardiac and non-cardiac origin, staying up late is a very important one.
Speaking of this, many people may refute it, after staying up late, I will make up for it, where is sudden death so serious.
But recently, the research team of the MRC Molecular Biology Laboratory in Cambridge, England, published a study in Nature Communications, which pointed out that the sodium and potassium levels inside the heart during the day and at night are different. This is a self-protection that the heart makes to itself, regulating the circadian rhythm by changing sodium and potassium. Let the heart enter a rest at night and "work" normally during the day, forming a well-regular biological clock. Some people who stay up late for a long time and cannot sleep at night will cause the normal biological clock of the heart to be destroyed, increasing the risk of sudden cardiac death and cardiac arrest.
In life, many young people do not care about staying up late, because they will use the time during the day to make up for sleep after staying up late. It's all sleep anyway, when isn't it all the same? Is this the right thing to do?
<h1 class="pgc-h-arrow-right" data-track="49" >2. Can staying up late be remedied? Just get a good night's sleep?
Of course not! </h1>
As we have said above, the heart has a certain protective mechanism, it can be adjusted in the body sodium, potassium to protect themselves, but staying up late will destroy the balance of sodium and potassium in the body, so the damage caused by staying up late to the body is "real", even if the next day sleep enough time, these damages have been caused.
During the nighttime sleep time, the various organs of the body will also repair themselves and rest, and once this time is missed, the rest time of the organs will also pass. Occasionally staying up late may not see major changes in the body, but in the long run, it will lead to endocrine disorders, decreased function of various organs, and even cause sudden death.
<h1 class="pgc-h-arrow-right" data-track="50" > third, sudden death without precursors, the appearance of these 3 major symptoms, pay attention to cardiac examination</h1>
Before sudden death occurs, the body actually has some abnormal manifestations, but these symptoms are easily ignored, so that the disease continues to develop.
1. Chest pain
Before sudden death occurs, many patients report chest pain and shortness of breath. These symptoms are clinically referred to as sudden death with chest pain and are due to pulmonary artery embolism.
2. Panic
Panic is also an important symptom of heart disease, before the occurrence of sudden death, patients will have irregular heart beats, palpitations, and some patients will have abnormal heart rate symptoms such as rapid heartbeat, slowness, and even due to abnormal heartbeat leading to insufficient cerebral blood supply induced syncope, sudden death caused by panic is mostly sudden cardiac death.
3. Tired
Feeling physically exhausted for no reason, and unable to relieve it after resting, it is time to be vigilant. Such people are often accompanied by symptoms of chest tightness and body edema.
<h1 class="pgc-h-arrow-right" data-track="51" >4. What tests should be done for suspected myocardial infarction? </h1>
So, if the above 3 symptoms appear, how should we further diagnose myocardial infarction when we suspect it?
Clinically, the gold standard for the diagnosis of myocardial infarction is "myocardial infarction three", including three indicators of myoglobin, troponin and creatine kinase isoenzyme.
Myoglobin is the oxygen-binding heme protein present in the heart muscle, which has the smallest molecule. Therefore, after myocardial injury, it will directly enter the blood circulation, and it is also the first indicator to react when the myocardium is damaged, and it is the most sensitive of the three myocardial infarctions, and abnormalities can be detected within 1 to 3 hours of onset. The reference index of myoglobin is: 20~80μg/L for men and 10~70μg/L for females.
Troponin refers to a complex of three proteins, including T, C, and I. After myocardial injury, troponin rises in the bloodstream within 4 to 6 hours. The biggest advantage of troponin indicators is that once the myocardium is damaged, the indicators can remain abnormal for 5 to 10 days, will not fall back immediately, have high specificity and sensitivity, and are one of the gold standards for diagnosing myocardial infarction.
Creatine kinase isoenzyme is an important indicator of acute myocardial infarction and myocardial necrosis, which is present in the myocardium and has a normal range of 0 to 25 U/L. When creatine kinase isoenzymes are abnormally elevated, be alert to myocardial damage caused by acute myocardial infarction, recurrent myocardial infarction, or some other non-myocardial factor.
Therefore, for people with a high incidence of myocardial infarction, or when suspected of having symptoms of myocardial infarction, it is recommended to go to the hospital in time to do myocardial infarction.
<h1 class="pgc-h-arrow-right" data-track="52" > five, protect the heart, and don't do these things</h1>
When you feel that there are some abnormal manifestations on your body, you must go to the doctor in time to avoid missing the best treatment time. In addition, you also need to pay attention to protecting the heart in life, these things should not be done again!
1. Get angry
Under the emotion of anger and anger, the blood circulation speed in the body will be accelerated, and the beating speed of the heart will also be accelerated, which is very easy to cause insufficient blood supply. In the long run, the normal function of the heart will be impaired, and some people with heart disease may have cardiac arrest due to sudden anger.
2. Long-term low mood
Emotions are very important for health, and being in a long-term depression, depression and other bad emotions will cause the body's normal breathing rate to be affected. It will also lead to abnormal increases in stress hormones in the body, making the burden on the heart become heavier, and it is very easy to cause heart disease in the long run.
3. Smoking
Smoking will bring a very big threat to heart health, tobacco harmful substances into the body will lead to an increase in epinephrine, norepinephrine secretion, will promote blood pressure increase, easy to cause hypertension, heart disease occurs; some people with coronary heart disease, smoking will lead to an increased risk of ventricular fibrillation, easy to cause sudden death; and a variety of harmful substances in tobacco, will lead to an increase in the risk of blood clots in the blood vessels, resulting in an increased risk of myocardial infarction.
Heart health is very important to each of us, and we must learn to protect our hearts in life and seek medical attention in time when abnormalities occur.
