Is cerebral infarction caused by atrial fibrillation scary?

The most obvious manifestation of atrial fibrillation is arrhythmia, which is especially serious in exciting situations. The incidence of this disease has been very high in recent years, second only to hypertension and coronary heart disease. This disease is a common cause of cerebral infarction, and once it occurs, it can be very scary. In mild cases, cerebral ischemia will occur, and in severe cases, sudden brain death may occur, and even life-threatening.

1. A set of data

Speaking of atrial fibrillation, I believe most readers will feel unfamiliar and distant. However, the following set of numbers may give you some understanding of atrial fibrillation. 8 million - There are currently about 8 million patients with atrial fibrillation in my country, which is a common cardiovascular disease after hypertension and coronary heart disease. 39% - 39% of people with hypertension are prone to atrial fibrillation, and patients with poorly controlled blood pressure are more likely to develop it. 5 times - Atrial fibrillation is a high-risk factor for cerebral infarction. The risk of cerebral infarction in patients with atrial fibrillation is 5 times higher than that of ordinary people.

2. How does atrial fibrillation cause cerebral infarction?

Atrial fibrillation is a common heart rhythm disorder. The risk of stroke in patients with atrial fibrillation is five times that of ordinary people. Once a stroke occurs, the mortality and disability rates are very high and the consequences are disastrous. How does atrial fibrillation cause cerebral infarction? Under normal circumstances, the contraction and relaxation of the heart are coordinated. When atrial fibrillation occurs, the irregular beating of the atria can cause blood flow disorder in the left atrium, especially blood congestion in the left atrial appendage, which can easily lead to thrombosis. After a blood clot breaks off, it will flow with the blood. Wherever it stops, it may cause blockage of the blood vessels in the corresponding part.

Once the left atrial appendage thrombus caused by atrial fibrillation breaks off, more than 90% of it runs into the brain. The thrombus blocks a certain place, and the ischemia there causes cerebral infarction, which we often call cerebral ischemia or stroke. Because the brain is one of the most important organs in the human body, different areas have different functions. Some areas are responsible for language, and if the thrombus blocks there, people will not be able to speak or will not be able to express themselves clearly. Some areas are responsible for vision, and if the thrombus blocks there, people will not be able to see.

3. Cerebral infarction

Cerebral infarction has become the leading cause of death among Chinese residents. Not only is the incidence rate, mortality and disability rate high, but the recurrence rate is also high, which brings a heavy burden to the family of every cerebral infarction patient. In our country, one person suffers from cerebral infarction every 12 seconds, one person dies from cerebral infarction every 21 seconds, and one in six people will suffer from cerebral infarction in their lifetime.
