Clinical manifestations of pulmonary embolism and pulmonary infarction

1. Dyspnea and shortness of breath are the most common symptoms of pulmonary embolism, mild cases of paroxysmal hyperventilation and shortness of breath after activity, severe cases of persistent dyspnea, shallow and rapid breathing, up to 40 50 beats per minute.

2. Chest pain includes pleuritic chest pain, which is manifested as aggravation of chest pain during breathing and coughing, indicating small peripheral pulmonary vascular embolism or pulmonary infarction; or colic-like pain in the heart of the nucleus, manifested by retrosternal asymmetric compression, which may radiate to the scapula and neck, suggesting acute dilation of the pulmonary arteries and coronary ischemia due to macrovascular embolism.

3. Syncope is also one of the symptoms of pulmonary embolism, and the reason why pulmonary embolism occurs is caused by cerebral ischemia caused by a sharp decrease in cardiac output, suggesting acute embolism of large vessels, which can be the only or first symptom of pulmonary embolism.

4. Pulmonary embolism is characterized by hemoptysis, usually a small amount of hemoptysis, and large hemoptysis is rare, bright red, and becomes dark red after a few days, indicating pulmonary infarction.

5. Patients with pulmonary embolism will have symptoms such as dyspnea and chest pain, and patients will inevitably feel irritability, emotional agitation, and even panic and death because of these symptoms.

6. The type of shock is extracardiac obstructive shock, in which a large emboli blocks the pulmonary vascular bed, coupled with strong pulmonary vasospasm, causing a sharp drop in cardiac output, a drop in blood pressure, and the patient often sweats profusely, is anxious, and in severe cases, sudden death. The incidence of group loss is about 10%.

7 About 43% of patients with pulmonary embolism have fever, often low-grade. Individual patients may have a temperature of 39 or higher. It can last for about 1 week. Causes may be related to pulmonary infarction, pulmonary hemorrhage, vasculitis, atelectasis, or infection.

The clinical manifestations of pulmonary embolism include: 1) dyspnea and shortness of breath, chest pain, syncope of chain clearing, hemoptysis, shock, and others such as supraventricular tachycardia, sudden onset or aggravation of congestive call heart failure, hyperventilation, etc. Signs include answers:

Pulmonary signs, cardiac signs, and thrombophlebitis in some patients.

Dyspnea is the main symptom of pulmonary embolism. Due to the blockage of the swollen artery, the proportion of ventilated blood flow is lost, and the alveoli are ventilated, but gas exchange is not possible.

Dyspnea, chest tightness, shortness of breath, syncope, cough, nausea, vomiting, hemoptysis, palpitations, these are the first symptoms of pulmonary embolism.

Clinical manifestations include cough, chest pain, dyspnea, cold sweats, paleness, syncope, and even hemoptysis, as well as tachycardia, shock, cyanosis, jugular venous distension and other signs. If you have such symptoms, be sure to go to the hospital for a check-up in time!

It will be very uncomfortable, and there will be chest pain and shortness of breath, and it will be very difficult to breathe, and the body will be very weak, and the body will become weaker and weaker, and the resistance will also decrease.

Dyspnea, fainting, shock, dizziness, heavy bleeding, chest tightness, shortness of breath, and in severe cases, sudden death.

There may be difficulty breathing, severe chest pain, coughing, coughing up blood, and abdominal pain.

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.
