Beware of “silent killer” — pulmonary embolism（PE）

With the development of medicine and people's attention to health, many diseases can be effectively controlled and even cured. However, there are also cases where some patients who seem to be in stable condition or who have no obvious disease inducement die suddenly. What is the reason?

In addition to the risk factors such as myocardial infarction and stroke, there is another risk factor called "pulmonary embolism", which is called "silent killer" by the medical community.

Pulmonary embolism, together with myocardial infarction and stroke, is one of the three major fatal cardiovascular diseases, with high mortality and disability rate. Moreover, its incidence is generally sudden and hidden, which is not easy to be found. The clinical symptoms and signs are also lack of specificity, which is easy to be misdiagnosed and missed, and the patients themselves do not know and pay attention to it. Therefore, pulmonary embolism is like a "silent killer", quietly lurking around us.

Only when we know ourselves and the enemy can we be invincible. How to prevent and drive away this "killer", let's first understand what is pulmonary embolism.

Pulmonary embolism is a series of pathophysiological changes that lead to respiratory and circulatory dysfunction and even sudden death after thrombus in deep vein falls off and reaches the pulmonary artery with blood circulation and blocks the pulmonary artery. Among them, long-term bedridden, tumor, obesity, heart and lung disease, even fracture, trauma, surgery and other patients are high-risk factors for the occurrence of pulmonary embolism. Therefore, patients with various diseases and even healthy people should prevent the occurrence of venous thrombosis.

Its main manifestations are:

Sudden onset of cough, chest pain, chest tightness, dyspnea, hemoptysis, syncope, fever, etc., of which dyspnea is the most common (80% - 90%), mostly sudden onset or sudden aggravation; It can also change from asymptomatic to decreased blood pressure or even sudden death; There are also some patients with hemoptysis and syncope as the first symptoms.
