    Atrial fibrillation. It can cause cerebral infarction, how is the thrombus formed? Blood circulationDisorders form blood clotsFor example, the systolic function of the heart is abnormal, common with atrial fibrillation, the heart loses its normal beating rhythm, the heart beats fast and slow disorders, the heart contraction is incomplete, the blood may form a vortex in the atrium, and a thrombosis may be formed.

    When our blood vessels are damaged, it will arouse the coagulation reaction of our body, causing various endogenous and exogenous coagulation, and activating a bunch of clotting factors.

    The liver is the chemical factory of our body, it breaks down toxins and kills germs, so that there is a normal and healthy (clean) blood supply. Our blood vessels are divided into arterial blood vessels and venous blood vessels, arteries and veins may form thrombosis, and our common arterial thrombosis is the myocardial infarction we just mentioned.

    cerebral infarction and so on. A common venous thrombosis is a blood clot in the veins of the lower extremities, after the vein of the lower extremity has broken off, or when it runs to the pulmonary blood vessels to block the pulmonary blood vessels.

    <>We often say "atherosclerosis."

    thrombosis", that's because atherosclerosis is the most common cause of arterial thrombosis. Atherosclerosis is more likely to form blood clots because the walls of the arteries are no longer smooth and intact. Some exogenous factors, such as major surgery, severe trauma, postpartum, etc., will cause the activation of the coagulation mechanism, resulting in easier aggregation of blood cells, therefore, after major surgery, in the case of severe trauma, etc., thrombosis prevention should be carried out**.

    Once a blood clot is formed, it will block the passages of blood vessels in various parts of the body like a plug, resulting in no blood in related organs**, resulting in sudden death. When a blood clot blocks a blood vessel in the brain, it leads to a cerebral infarction. in the coronary arteries.

    A myocardial infarction is formed.

    Blockage to the lungs is called "pulmonary embolism."

    The degree of blood stickiness, such as slow blood flow, etc., is difficult to avoid when we get older, and all we can do is to minimize the risk of thrombosis.

    Arteriosclerosis occlusion of the lower extremities refers to the narrowing and occlusion of the lumen of the arteries of the lower limbs, causing ischemic diseases of the feet of the lower limbs. The main cause is arteriosclerosis, which is caused by lifestyle factors such as high blood pressure, abnormal metabolism, smoking, sedentary lifestyle, obesity, and lack of exercise. In addition, age, gender, and genetic factors will also have a certain impact on the onset of arteriosclerosis obliterans of the lower extremities.

    To prevent and control arteriosclerosis occlusive disease of the lower limbs, physical exercise should be strengthened, smoking should be stopped, alcohol should be limited, blood pressure, blood lipids and blood sugar levels should be controlled, a healthy weight should be maintained, and regular physical examinations should be conducted. If you have symptoms such as numbness, pain, and muscle atrophy in the lower limbs, you should seek medical attention in time to avoid seriously affecting the quality of life.

    Atrial fibrillation can cause cerebral infarction, what is the cause of blood clots?

    The normal sinus rhythm frequency is 60-100 beats, and the two atria contract in harmony with each other, making it difficult to form blood clots. In atrial fibrillation, the frequency of atrial electrical activity reaches 350-600 minutes, the speed is relatively fast, and the contraction of the two atria is uncoordinated, that is, part of the atrial contraction and part of the atrial relaxation, so that the entire atrium is in a peristaltic state (also called atrial fibrillation), which will lead to slowing down of blood flow and thrombosis. The left atrium also has an ear called the left atrial appendage.

    During a normal heartbeat, blood flow to the left atrial appendage is also regular. In the case of atrial fibrillation, the atria itself is in a state of peristalsis, and the left atrial appendage is closer to rest. It was like a pocket that contained a portion of the blood flow, which quickly formed a blood clot.

    the relationship between atrial fibrillation and cerebral infarction; Eighty-five percent of embolic events caused by atrial fibrillation are cerebral infarctions. According to the American Heart Rhythm Association's guidelines for the management of atrial fibrillation, patients with atrial fibrillation have five times the incidence of cerebral infarction compared with healthy people. The risk of cerebral infarction increases with age, and cerebral infarction associated with atrial fibrillation is more severe than that associated with non-atrial fibrillation.

    The 30-day mortality rate is 27% 57% higher than that of patients without atrial fibrillation, the disability rate is doubled, and the mortality rate and ** rate within 1 year are twice that of patients without atrial fibrillation.

    If atrial fibrillation is diagnosed, it is important to take anticoagulants to prevent thrombosis. Traditional anticoagulants mainly include heparin-based anticoagulants, such as low molecular weight heparin, fondaparinux, and vitamin K antagonists (such as warfarin). Newer anticoagulants mainly include intravenous or oral thrombin inhibitors and activated factor inhibitors.

    Although the new anticoagulant has many advantages, it cannot completely replace the traditional anticoagulant at present.

    Although anticoagulants carry a risk of bleeding, it is necessary to monitor blood clotting indicators, pay attention to a healthy and stable lifestyle, and even try to ensure that the overall habits of eating vegetables do not change much, but the cost of these preventive measures is overestimated compared to cerebral infarction caused by atrial fibrillation! At the same time, patients with atrial fibrillation are often complicated by other heart diseases, and they need to be comprehensively treated under the guidance of specialists** in order to be at ease! In addition, atrial fibrillation may also often be complicated by heart disease such as high blood pressure, and it is necessary to take relevant drugs to control the three highs, and at the same time, ** heart disease.

    It is because the cerebral blood supply is insufficient, the blood vessels are blocked, and the body hormones rise due to agitation, so blood clots will form.

    The formation of thrombosis refers to the formation of cerebral arterial wall thrombosis in the case of slow blood flow, changes in blood composition or increased blood viscosity on the basis of atherosclerotic pathological changes in the arterial blood vessel wall of the brain inside and outside the brain, which narrows the cerebral vascular lumen or blocks the thrombosis, and eventually leads to cerebral blood circulation disorders, cerebral ischemia or infarction. Thrombosis has a dual effect, if the size of the thrombus is relatively small, it can play a role in stopping bleeding, if the volume is relatively large, it will block the blood vessels, resulting in poor blood circulation, which may cause infarction for a long time. The body's blood has clotting and anticoagulation mechanisms, which can also lead to the formation of blood clots if it is disrupted.

    It should be that there is a problem with the cardiovascular surface, so it causes a blood clot, and the problem of blood clot is sometimes sudden, and it also needs special care and maintenance.

    Because it is a symptom caused by abnormal discharge of the coronary arteries, it is prone to ischemia and hypoxia, so it is easy to cause cerebral infarction. Thromboembolism is generally caused by thick blood or high blood pressure, coronary heart disease, diabetes, not liking exercise, and long-term sedentary, which will lead to thromboembolism.

    Atrial fibrillation is a type of heart disease, atrial fibrillation can lead to insufficient blood supply to the brain, which can cause cerebral infarction, thrombosis is the blood entering the circulatory arteries, and the blood vessels are urgently blocked or severely narrowed.

    First of all, because the human blood is not smooth and blocked for a long time, the blood cannot circulate smoothly, which will lead to thrombosis in the long run.
