First, the causes of symptoms
1, cardiovascular endothelial cell injury
The injury of cardiovascular endothelial cells is the most important and common cause of thrombosis. It is more common in rheumatic and infectious endocarditis, endocardium in myocardial infarction area, severe atherosclerotic plaque ulcer, arteriovenous trauma or inflammatory injury. Hypoxia, shock, sepsis and bacterial endotoxin can cause extensive endothelial damage, activate coagulation process, cause disseminated intravascular coagulation, and form thrombus in systemic microcirculation.
2. Abnormal blood flow
Mainly refers to the slow blood flow, blood vortex, which is conducive to the formation of thrombosis. Vena is more prone to thrombosis than artery, which often occurs in patients with heart failure, chronic diseases and bedridden after operation. Although the blood flow in the heart and artery is fast, it is not easy to form thrombus, but the blood flow in the left atrium, aneurysm or vascular branch is slow, and it is easy to form thrombus when vortex appears.
How to prevent thrombosis?
1, primary disease treatment: actively treat diseases that may lead to thrombosis, such as hypertension, hyperglycemia, hyperlipidemia, cor pulmonale, infection, etc.
2, adjust the diet structure: pay attention to a reasonable diet, so as to achieve a low-salt, low-fat, low-cholesterol diet. In the usual diet, we should put less salt, eat some fresh fruits and vegetables in moderation, and avoid eating fat, squid and spicy food. These foods can easily lead to plaque formation in blood vessels. Minimizing and avoiding eating these foods will help prevent thrombosis to some extent.
3. Strengthen exercise: such as swimming, brisk walking, jogging, playing basketball, practicing Tai Ji Chuan, etc. By properly strengthening exercise, it is beneficial to accelerate the metabolism of the body and prevent excessive accumulation of fat to a certain extent, thus preventing thrombosis. 4. Change posture regularly: If the patient stays in bed for a long time after operation, he should get out of bed as early as possible according to the doctor's advice to reduce the occurrence of deep venous thrombosis.
5, the use of anti-thrombotic elastic socks: those with high-risk factors should follow the doctor's advice to apply anti-thrombotic elastic socks to reduce the occurrence of thrombosis.
