There is a blood vessel in the human body that comes from the heart, walks in the chest and abdominal cavity, and connects various organs, called the "aorta".

It is the thickest blood vessel on the whole body and the most stressed. Once it breaks, the blood will break like the dam of the Yellow River , and the person's breathing and heartbeat may stop at any time.

A study published by Beijing Anzhen Hospital affiliated to Capital Medical University and Yale New Haven Hospital in the United States shows that in October of each year, aortic dissection (simply put, the aortic split) has the highest incidence.

" Life Times " interviews authoritative experts to teach you to see through the signals of aortic rupture as soon as possible and do scientific prevention.

Every October, the aortic dissection is high in incidence

0 Aorta is like an arcuate duct, emanating from the left ventricle, upward, right, and downward, downward, along the spine, and transporting blood to various organs throughout the body.

The aortic vessel wall has three layers, divided into inner membrane , middle membrane and outer membrane, with the diameter of the thickest part reaching 2.8~3 cm. If there are risk factors such as hypertension and , arteriosclerosis, the impact force of the blood flow will tear the endometrium, and the blood will run between the inner and outer membranes, forming an aortic dissection. In layman's terms, it's blood vessels that are split.

Beijing Anzhen Hospital Professor Sun Lizhong's team and researchers from Yale New Haven Hospital in the United States selected research subjects from their hospitals, and a total of 1,642 patients with acute aortic dissection were included, including 1,397 Chinese patients and 245 American patients.

After sorting out, the researchers found that the incidence of acute aortic dissection has a certain time pattern:

• During one year, the incidence of acute aortic dissection was significantly increased in October compared with May to August every year.

  Among them, the incidence rate in October was the highest, at 10.5%; followed by February and December; and the incidence rate in August was the lowest.

  • During one month, the incidence of acute A-type aortic dissection is higher before and after the fifteenth lunar calendar.
    • During the week, the high incidence rate on Wednesday was the highest (15.5%), once a week (15.2%), and the lowest incidence rate on Sunday (12.8%).

      researchers believe that the occurrence of acute aortic dissection is related to temperature and pressure. This research result is of great significance to understanding the trigger mechanism of the disease and helps to improve the current prevention and treatment status of this disease.

      What is the experience of aortic splitting?

      Once aortic dissection occurs, it is equivalent to a dangerous situation in the core part of the blood circulation. The patient will feel heart-wrenching and severe pain in the front chest and back, and the pain can spread to the abdomen.

      If treatment is not done in time, the blood flow will break through the outer wall of the blood vessel and cause heavy bleeding. shock , death is a matter of moment.

      

      Clinically, there are three common fatal chest pains: aortic dissection, acute myocardial infarction, and pulmonary embolism. The difference is:

      • chest pain caused by acute myocardial infarction has a feeling of tightness, compression, heaviness, and stuffy , rather than a sharp pain like a knife cut. Chest pain ranges from “a piece” the size of a fist or palm, not a point or line.
      • Pulmonary embolism can also be manifested as chest pain, but it is often accompanied by dyspnea, hold back breath, and is obvious after activity.
      • If there is sharp pain in the front chest, back, and abdomen, it is suspected that it is an aortic dissection.

      Doctors named 5 types of dangerous people

      In my country, aortic dissection mostly occurs in young and middle-aged people, common in the age of 40-50, and even born in the 1990s, more men than women.

      

      Doctor reminds that there is a relatively obvious high incidence of aortic dissection. The following 5 categories of people should be particularly vigilant:

      Hypertension patients

      Hypertension is the main reason. Some people usually control their blood pressure well, but when they are overworked and breath-holding, their blood pressure may be transiently increased, which may induce aortic dissection.

      people with arteriosclerosis

      Such human blood vessels are deteriorated. The moment the upper body suddenly twists, stretches or lifts, the aorta is violently pulled, which may cause blood vessel tear.

      Abdominal obese people

      The abdominal fat is more likely to cause the diaphragm to rise and the roots of the aorta are under more pressure. By the same token, pregnant women should also pay attention to preventing aortic abnormalities due to the existence of fetus.

      patients with Marfan syndrome

      people have congenital defects in the heart and large blood vessels, and the middle layer of the blood vessels is very weak, which is prone to aortic dissection.

      s who have suffered severe trauma

      Especially for people who fall or hit from too high, the aorta is also prone to problems.

      In addition, high working pressure, high tension, smoking, alcoholism, etc. are also important reasons for the occurrence of aortic dissection.

      control of high-risk factors is the key to preventing

      Aortic dissection is a critical cardiovascular disease with a high mortality rate, but it can be prevented and controlled. The key is to remove high-risk factors.

      1

      Control blood pressure

      Actively controlling blood pressure is the primary priority. Patients with hypertension should monitor their heart rate, pulse, and blood pressure by themselves and control them within a reasonable range.

      In life, avoid factors such as being overjoyed, staying up late, and overwork that may cause sudden blood pressure rise, and try to keep your stools unobstructed.

      2

      Prevention and treatment of arteriosclerosis

      Modern people have gradually increased and their age is getting older and older due to dietary structure adjustment and physical activity reduction in modern people.

      Actively improve lifestyle, control calorie intake, and try to eat as much as possible one pound of vegetables and half a pound of fruit every day.

      exercise regularly, accumulate 150~300 minutes of moderate intensity exercise every week, or 75~150 minutes of high intensity exercise.

      3

      3Reduce sudden force

      The elderly have arteriosclerosis, and in life, they should try to avoid sudden and large-scale twisting and stretching of the upper body.

      For example, when you get up and stand up from the sofa, you should move slowly; it is best to have a handrail next to the toilet in the toilet, so you can borrow some force when you get up.

      4

      avoid trauma as much as possible

      If car accident injuries or fall injuries, these forces can cause extensive tearing of the aortic endometrium in the injured locally and distantly, causing one or more clefts of the aortic dissection.

      5

      attention to physical examination

      Hand color ultrasound and flat X-ray films help to early detection of the aortic dissection, enhance CT and MRI to make clear diagnosis.

      

      People with hypertension, frequent staying up late, high psychological pressure, long-term smoking and alcoholism should focus on chest X-ray examinations and ultrasound during the physical examination. If there is any abnormality, please seek medical treatment in time, don’t be careless. ▲
