MedicalResearch.com: What is the background for this study?
Response: Syncope is a common symptom that occurs in one in four people during their lifetime. Pulmonary embolism (PE) has long been recognized as an important and serious cause of syncope. PE has always been estimated a rare cause of syncope, present in less than 1.5% of patients. A recent study (PESIT), aiming at evaluating PE prevalence using a standardized algorithm in hospitalized patients after a first syncope episode, found a prevalence of PE as high as 17% in hospitalized patients. This means that patients with a first episode of syncope should be investigated with a standard diagnostic algorithm to exclude PE.
However, many patients might go through useless and potentially harmful tests, such as computed tomography pulmonary angiogram.
