Pulmonary embolism may be a clinical syndrome caused by the blockage of the pulmonary artery and its branches by emboli such as amniotic fluid, fat, air, and blood clots, and patients may experience symptoms such as dyspnea, chest pain, fainting, and hemoptysis.
1. Difficulty in breathing: after the pulmonary artery is blocked by the embolus, the blood supply to the lungs will be insufficient and the lung function will be reduced, so the patient will have the symptom of dyspnea, and in severe cases, the patient will have a sense of near death.
2. Chest pain: pulmonary embolism will lead to a decrease in blood supply and oxygen to the heart, angina pectoris induced by ischemia and hypoxia of cardiomyocytes, and pleuritic chest pain after the emergence of pleural effusion.
3. syncope: pulmonary embolism leads to cerebral ischemia and hypoxia, patients will experience transient loss of consciousness, inducing syncope, shock-induced syncope may lead to sudden death.
4. Hemoptysis: when the condition is more serious and causes pulmonary infarction, it will lead to hemorrhagic pulmonary atelectasis, resulting in hemoptysis, and the amount of bleeding is usually small.
It is recommended that the patient go to the hospital in time, and carry out the relevant treatment under the guidance of the physician.
