Update on the diagnosis and management of pulmonary embolism

Abstract

Pulmonary embolism (PE) is a common and often fatal disease. In the US, an estimated 40-53 people per 100 000 are diagnosed with PE annually and approximately 60 000 die from the disease. Diagnosis is difficult because symptoms are non-specific; however, a quick and accurate diagnosis is critical because, with appropriate therapy, the risk of recurrent (and potentially fatal) PE can be greatly reduced. Recent publication of prediction rules and improved non-invasive diagnostic tools have simplified diagnostic algorithms for PE. The efficacy of the standard treatment for PE, initial administration of continuous i.v. unfractionated heparin overlapped with long-term oral anticoagulation, is well established. However, newer treatment options such as low-molecular-weight heparins and the pentasaccharides may offer similar efficacy with improved convenience. © 2005 Blackwell Publishing Ltd.
