The most common cause of pulmonary infarction

The main cause of pulmonary infarction is thrombosis and cardiopulmonary disease. In our life, when varicose veins occur, we should relieve them through massage, otherwise it will cause symptoms of pulmonary infarction. There are many causes of pulmonary infarction. You can read the content introduced in the article, correctly treat the causes of pulmonary infarction, and then choose the correct treatment method.

1. Blood clots

In clinical practice, the pathological change of thrombosis and pulmonary embolism is often a complication of venous thrombosis in the human body. Emboli usually originate from the deep veins of the lower limbs and pelvis, and can cause embolism by circulating to the pulmonary artery. But generally speaking, this type of thrombus rarely originates from tissues such as the upper limbs, head and neck veins. Blood stasis in the human body, increased blood coagulability and varying degrees of venous endothelial damage are factors that promote thrombosis in clinical practice. Therefore, this means that the human body is prone to venous thrombosis after being troubled by adverse factors such as trauma, intravenous catheterization, pelvic and hip surgery, long-term bed rest, varicose veins, obesity, diabetes, contraceptives, or other reasons for hypercoagulation.

2. Cardiopulmonary Disease

Chronic cardiopulmonary disease is the main risk factor for pulmonary thromboembolism. Many patients with pulmonary embolism often have cardiopulmonary disease after the onset of the disease. Patients with cardiovascular disease may also have atrial fibrillation, heart failure and subacute bacterial endocarditis.

3. Tumor

This type of cause is mainly some difficult and common diseases such as lung cancer, digestive system tumors, choriocarcinoma, leukemia, etc. After the onset of malignant tumors, only about one-third of pulmonary embolism is caused by tumor thrombus, while the rest of the patients have blood clots. In addition, studies have found that the reason why patients with malignant tumors are prone to pulmonary embolism may be related to abnormal coagulation mechanism in the human body.

IV. Pregnancy and Childbirth

The incidence of pulmonary embolism is highest in two stages: after delivery and after cesarean section. This is mainly because the intra-abdominal pressure of women increases during pregnancy. At the same time, hormones relax vascular smooth muscles, pelvic veins are compressed, etc., which can cause the body's venous blood flow to slow down and change the blood rheology properties, thus aggravating venous thrombosis. In clinical practice, amniotic fluid embolism is also a serious complication during delivery.

The above is an introduction to the causes of pulmonary embolism. I believe that the questions in the patients’ minds have been answered after reading it. In order to prevent the occurrence of difficult diseases such as pulmonary embolism, we must pay attention to establishing a healthy lifestyle and actively exercising in our daily lives. We must seek early treatment after the primary disease occurs to stay away from the harm of this disease.
