Pulmonary embolism '''Incorrect:''' Pulmonary embolism refers to the blockage of the pulmonary vasculature by a substance from elsewhere in the body, most commonly a blood clot. Pulmonary embolism is associated with sudden onset chest pain, tachycardia, and shortness of breath. Risk factors for pulmonary embolism include immobility, a past thromboembolic event, and any other causes of hypercoagulable state.
