Background: Management of syncope in accordance with a guidelines-based algorithm has recently been shown to improve the rate of diagnosis. This algorithm is not yet widely used in Japan, however. This report describes comprehensive risk stratification by means of a guidelines-based algorithm in current clinical practice in Japan, and an attempt to clarify the frequency of cardiac syncope.
Methods: Data on consecutive patients presenting with syncope between April 2012 and March 2014 were retrospectively reviewed and clinical characteristics analyzed. Our syncope management strategy is based on guidelines published by the Japanese Circulation Society and European Society of Cardiology.
Results: A total of 210 patients were included in the analysis. Risk factors for cardiac syncope were defined by the guidelines. Cardiac syncope was diagnosed in 25％ of the patients following guidelines-based evaluation. Cardiac syncope was more frequent in patients with at least one risk factor in this Japanese population. The rate of recurrence of syncope in patients in whom management was completed in accordance with the guidelines was lower than that in those it was not.
Conclusion: A syncope unit and management in accordance with current guidelines are useful in improving the rate of diagnosis and preventing recurrence.
