Validation of Different Risk Assessment Strategies in Normotensive Pulmonary Embolism

A risk stratification in hemodynamically stable patients with acute pulmonary embolism (PE) is deemed necessary to guide patient management. With the aim to improve the positive predictive value (PPV) for PE-related adverse events in in normotensive patients, a number of scores combining multiple risk-factors have been published. In addition, an algorithm for the risk-stratification of patients with PE has been proposed by the European society of cardiology. None but one of these scores underwent external and prospective validation. The aim of this study is to externally and prospectively validate the PPV for PE-related adverse events of the Bova score and modified FAST score in a large multicenter cohort.
