Recently, the news of the sudden death of Ding Yun, the vice chairman of the board of supervisors of Huawei, has been popular. Ding Yun loves marathons, even to the extent of obsession. He also practiced half a marathon with his colleagues the day before his sudden death and ran a long distance28km, so many people attribute Ding Yun's sudden death to running.
In recent years, there are more and more cases of sudden death from running. Not long ago, Dr. Sun Jian, chief scientist of Kuangsi and president of Kuangsi Research Institute, also ranHe died of a sudden illness 10 kilometers later at the age of 46.
However, it is also reported that Ding Yun died of sudden pulmonary embolism after drinking. Drinking is the main cause of sudden death(Ps: information comes from the network). This news still has some credibility, because Ding Yun didn't die suddenly while running, but ran in the daytime and died in the morning the next day.
Speaking of sudden death, most people think it is a heart problem. What about sudden death from pulmonary embolism?
Pulmonary embolism, known asThe "King of Sudden Death" is a disease that makes physicians, surgeons, orthopedics, oncologists and other department doctors feel scared and mad. If the rescue is not timely, it will be fatal every minute and extremely dangerous.
As the name suggests, pulmonary embolism, like cerebral embolism, is that the blood vessels of the lung are blocked by thrombus, resulting in the blood flow of the pulmonary vessels.
Because there are many blood vessels in the lung, it should not be a problem to block a blood vessel according to common sense, but this is not the case in fact. Generally, after pulmonary embolism, it will cause extensive spasm of blood vessels in the lung, so that the blood in the heart cannot pass, and the following symptoms will occur:
1. Dyspnea and shortness of breath
The degree and duration of dyspnea may be related to the size of thrombus, and the symptoms may be mild or severe. When the thrombus is large, dyspnea is serious and lasts for a long time; The scope of embolism is small, with only temporary dyspnea or only lasting for a few minutes. Some patients have recurrent small embolism, which can cause sudden dyspnea for many times.
Dyspnea is characterized by shallow and fast breathing and laborious breathing.
2. Chest pain
It includes pleurisy chest pain and angina pectoris like chest pain, of which pleurisy chest pain accounts for the majority and is manifested in unilateral or bilateral flank pain. The pain is caused by the cellulitis of the pleura involved by the distal pulmonary artery embolism. The pain is manifested in acute pain, which is aggravated when breathing or coughing. The change of body position during activity can also aggravate the pain;
However, angina pectoris is in the minority. The pain is caused by pulmonary hypertension caused by pulmonary embolism, which reduces the amount of blood returning to the left ventricle and the corresponding amount of blood ejected. It can not guarantee the blood supply of the systemic circulation, which leads to hypotension, and reduces the blood supply of the coronary artery supplying the heart. At the same time, coronary artery spasm is also one of the reasons for angina pectoris. Angina pectoris can be expressed as squeezing sensation and suffocation behind sternum, or as needle-like sharp pain in precordial area, and can radiate to scapula and neck, which has no obvious relationship with respiration and cough.
3. Syncope
It can be the first or only symptom of pulmonary embolism, can indicate the existence of large pulmonary embolism, and can be accompanied by cerebral blood insufficiency during the attack, which should be differentiated from central nervous system disease.
4. Palpitation and near-death feeling
The incidence rate is high, which is a common symptom of pulmonary embolism, mainly caused by severe dyspnea and severe chest pain. Due to the severity of the disease, the severity of such symptoms varies greatly, and the symptoms develop with the development of the disease.
5. Hemoptysis
That is, coughing and bleeding when coughing, not vomiting and bleeding when vomiting, usually small amount of hemoptysis, and large hemoptysis is rare. Because the bleeding site is in the alveolus, the blood and sputum are mixed evenly and have the same color, which is bright red in the early stage and dark red after a few days.
The incidence of hemoptysis in patients with pulmonary embolism is not high. The main causes of hemoptysis are pulmonary infarction and hemorrhagic atelectasis, more of which are caused by the latter. In acute pulmonary embolism, hemoptysis mainly reflects the bloody exudation of local alveoli, which does not mean that the disease is serious. On the contrary, because pulmonary infarction is mostly caused by obstruction of pulmonary artery, the prognosis may be better.
6. Cough
Most of them are dry cough, which can also be accompanied by a little white sputum or wheezing. The cough of patients with pulmonary thromboembolism may be caused by the inflammatory reaction caused by pulmonary embolism that stimulates the respiratory tract, or by the increase of exudates in the alveolus that stimulates the cough reflex, which may appear soon after embolism.
Once the above occursFor the six symptoms, we must go to the hospital for examination as soon as possible, and never take it lightly.
