Why does hyperlipidemia cause pulmonary embolism?

The disease is mainly due to various reasons, resulting in little movement of the limbs, resulting in thrombosis of the lower limbs or deep veins, when the blood flow slows down, the detached embolus can flow down the blood into the lungs, forming an acute pulmonary embolism.

Pulmonary embolism is generally considered to have a high incidence in the West, for example, 630,000 people in the United States occur every year, accounting for the third cardiovascular incidence, of which 50,000 people die due to untimely death, and the mortality rate is second only to tumor and myocardial infarction. The reason why there are few discoveries in China may be related to our lack of understanding of this disease and backward examination methods, and there is a possibility of missing the diagnosis.

The vast majority of embolisms are deep vein thrombosis, and the basic causes of deep vein thrombosis are slow blood flow, damage to blood vessel walls, atherosclerosis, etc.

It is common in obese people, the elderly (especially those with hyperlipidemia), long-term bed rest, quiet sitting (such as in front of the computer, mahjong night battles, long-distance planes, trains, ships, etc.) and inactive. Pelvic vein thrombosis is easy to occur due to pelvic vascular compression in pregnancy, and varicose veins of the lower limbs are also prone to formation in various long-standing professions (such as surgeons and barbers), and varicose veins are easy to form thrombosis. Trauma, surgery, chronic heart and lung disease, oral contraceptives, and certain blood disorders can cause deep vein thrombosis, increasing the risk of embolism.

Pulmonary embolism is due to endogenous or extrinsic emboli, blocking the main trunk and branches of the pulmonary artery, resulting in the interruption of blood flow in the pulmonary artery, causing a series of clinical manifestations, pulmonary embolism is a very critical disease, and the mortality rate of acute pulmonary embolism is not inferior to that of myocardial infarction in clinical observation.

In clinical practice, it is found that most of the pulmonary embolism is caused by venous thrombosis of the lower limbs, varicose veins of the lower limbs, trauma or sedentary lifestyle, will cause thrombosis in the veins of the lower limbs, this blood stasis, slow blood flow and the destruction of the endothelium make the veins of the lower limbs form thrombosis, the thrombus of this vein will reflux with the venous blood, reflux to the right atrium, right ventricle, through the pulmonary valve to the pulmonary artery, if this thrombus also along with the venous blood, to the pulmonary artery and the main trunk and its branches, This can lead to pulmonary embolism. If the pulmonary embolism is severe, it will affect the circulation, causing circulatory disorders, and this acute circulatory disorder can even be life-threatening, so pulmonary embolism, especially acute pulmonary embolism, should be vigilant.

Acute pulmonary embolism is possible if diagnosed promptly. Pulmonary hypertension usually does not occur. Most patients with embolic pulmonary hypertension are bent by not receiving timely diagnosis and treatment.

For your condition, you can have a semi-annual heart ultrasound to know if you have pulmonary hypertension.

Disease analysis: high blood lipids can cause atherosclerosis and then cause cerebral thrombosisOpinion suggestion: diet.

1) Limit fat intake The daily diet should reduce the total amount of fat, increase polyunsaturated fatty acids, reduce animal fat, and make the ratio of ps to the above, so as to reduce the synthesis of endogenous cholesterol by the liver. When cooking, do not use animal oil, but use vegetable oil, such as soybean oil, peanut oil, corn oil, etc., the dosage is 25 grams per person per day, and it is advisable to use less than 750 grams per month. To limit cholesterol in foods, you should eat less than 300 mg per person per day, that is, you can eat 3 egg yolks per week.

2) Control the total calories.

3) Increase protein in moderation.

4) Limit refined sugars and sugary sweets.
