Aortic dissection: a more frightening form of chest pain than acute myocardial infarction!

Everyone knows that cardiovascular and cerebrovascular diseases such as myocardial infarction and infarction are life-threatening, but few people know that aortic dissection is more dangerous than these diseases. Many celebrities died of aortic diseases such as Einstein, Lincoln, and Li Siguang. The American volleyball star Hyman and the Chinese men’s volleyball player Zhu Gang died of aortic dissection.

Patients with acute aortic dissection can die suddenly or die within hours or days without leaving any opportunity for treatment. Studies have shown that 50% of patients with aortic dissection will die within 48 hours, 70% will die within 1 week, and 90% of patients will die within 3 months. It can be said that the aortic dissection is dead for nine lifetimes.

The aorta is the body’s thickest main blood vessel. It is sent directly from the heart and is under strong pressure from the heart pumping blood. Internal blood flow is huge. Due to the great pressure and blood flow of the aorta, once the wall of the aortic blood vessel is torn, the chance of major bleeding is very high and the mortality rate is extremely high.

How does the aorta clip the layer?

Aortic dissection refers to aortic intima tearing under a series of external causes (hypertension, trauma, etc.). Blood has an intimal tear that enters the middle of the aorta, causing aortic medial dissection and thus the arterial tube. The cavity presents a true or false lumen.

What are the symptoms of aortic dissection?

1. Typical symptoms of aortic dissection are often sudden, severe, chest-back and tear-like pain. Serious can be manifested as heart failure, syncope, or even sudden death.

2. Long-term presence of most patients with aortic dissection failed to control hypertension.

3, in addition to the above symptoms and history, with the accumulation of different organs in the aorta, there may be left recurrent laryngeal nerve compression and paralysis occurs, dissection through the trachea or esophagus can occur hemoptysis and vomiting blood, oppression of the trachea can have difficulty breathing, oppression Pulmonary arteries may have pulmonary embolism. Involvement of the mesentery and renal arteries may present with paralysis and kidney infarction.

Once the diagnosis of acute aortic dissection is suspected, the confirmed diagnosis mainly includes aortic angiography, CT-enhanced angiography (CTA), and magnetic resonance angiography (MRA).

Who is most likely to suffer from aortic dissection?

1, high blood pressure crowd

Almost all patients with aortic dissection have a history of hypertension. It can be said that the most common cause of aortic dissection is hypertension. At the same time, it is pointed out that most of these patients with aortic dissection will have poor aortic dissection with poor blood pressure control. The incidence of aortic dissection in patients with hypertension with good blood pressure control is low.

2, pregnancy

Pregnancy is another high risk factor for aortic dissection, which is related to changes in hemodynamics of pregnant women during pregnancy. Studies have shown that 50% of patients who had an aortic dissection before age 40 occurred during pregnancy.

3, other factors

Common causes of aortic dissection include: Marfan syndrome, congenital cardiovascular malformations, multiple arteritis, aortic atherosclerosis, idiopathic aortic medial degeneration and so on.
