What is a key symptom of pulmonary embolism?

Chest pain that worsens with breathing is a key symptom of pulmonary embolism due to the condition's impact on the lungs and the pleura. When a blood clot travels to the lungs, it can cause a blockage in the pulmonary arteries, leading to respiratory distress and resulting in sharp, sudden chest pain. This pain often intensifies with deep breathing, coughing, or movements, which is characteristic of pleuritic pain—pain that originates from the lungs or pleura being inflamed or irritated.

The presence of this symptom is quite significant, as it can help distinguish pulmonary embolism from other medical conditions that might present with similar symptoms. In addition to chest pain, patients may also experience other symptoms such as shortness of breath, rapid heart rate, and sometimes coughing up blood. Recognizing chest pain that worsens with respiratory movements is crucial for timely diagnosis and treatment of pulmonary embolism, potentially preventing severe complications or death.
