Pulmonary embolism is a potentially life-threatening condition in which a blood clot forms in a deep vein, typically in the legs, and travels to the lungs where it blocks blood flow. This can lead to serious complications such as difficulty breathing, chest pain, and even death if not treated promptly. Research in the area of pulmonary embolism focuses on improving diagnostic methods, developing new treatments, and identifying risk factors for the condition. This research is important for improving outcomes and reducing mortality rates associated with pulmonary embolism.
