Why the study?
Accurate risk stratification is needed to prevent adverse outcomes and optimize healthcare resources until an optimal and well-validated risk score for syncope is available.
Current clinical decision rules for syncope require further validation, making adherence to ESC guideline-based initial assessment essential for accurate risk stratification.
ESC guideline-based assessment should guide syncope risk stratification; leaves open need for well-validated decision rules.
Syncope is a common clinical presentation defined as a transient loss of consciousness (TLOC) due to cerebral hypoperfusion, characterized by a rapid onset, short duration, and spontaneous complete recovery. Different clinical decision rules (CDRs) and risk stratification scores have been developed to predict short- and long-term risks for adverse outcomes after syncope. The central theme of these prediction systems is consistent with the ESC syncope guidelines. Initial assessment according to the ESC guideline is essential until an optimal and well-validated risk score is available. The focus should be accurate risk stratification to allow prevention of adverse outcomes and optimize the use of limited healthcare resources. In this review article, we summarize and critically appraise the evidence regarding the CDRs for patients presenting with syncope.
