Explore Pulmonary Embolism
Signs and symptoms of pulmonary embolism (PE) include unexplained shortness of breath, problems breathing, chest pain, coughing, or coughing up blood. An arrhythmia (irregular heartbeat) also may suggest that you have PE.
Sometimes the only signs and symptoms are related to deep vein thrombosis (DVT). These include swelling of the leg or along a vein in the leg, pain or tenderness in the leg, a feeling of increased warmth in the area of the leg that's swollen or tender, and red or discolored skin on the affected leg.
See your doctor right away if you have any signs or symptoms of PE or DVT. It's also possible to have PE and not have any signs or symptoms.
Some people who have PE have feelings of anxiety or dread, light-headedness or fainting, rapid breathing, sweating, or an increased heart rate.
Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans. To find clinical trials that are currently underway for Pulmonary Embolism, visit www.clinicaltrials.gov.
