Pulmonary embolism is generally caused by the detachment of deep vein thrombosis. Once detached, the clot travels through the bloodstream to the pulmonary artery, where it can cause blockage and lead to pulmonary embolism—this is the primary cause of the condition. Severe cases may result in difficulty breathing, respiratory failure, and pose significant risks. Patients often experience obvious symptoms such as chest tightness, shortness of breath, and chest pain. Prompt diagnosis and treatment are essential, as the condition can be life-threatening if left untreated.
