Background: The American College of Physicians (ACP) and the American College of Emergency Physicians (ACEP) recently published practice guidelines and recommendations for evaluation of patients with syncope based on historical, physical, and ECG findings. The objective of the present study was to determine if risk stratification using these practice resources is valid in a series of Japanese patients. Methods and Results: A total of 912 consecutive patients brought to our emergency department between 1988 and 1997 because of syncope were identified. Follow-up information about mortality was obtained for 707 patients by means of mailed questionnaires and from medical records, and the mortality data were analyzed by the actuarial life-table method. A total of 187 patients who fulfilled the admission criteria according to the ACP guidelines were found to have higher overall and cardiac mortality than the other 520 patients (P < 0.0001), and 153 patients who fulfilled the admission criteria according to the ACEP recommendations also had higher overall and cardiac mortality than the other 554 patients (P < 0.0001). Conclusions: The recent American practice recommendations can be used for risk stratification of syncope patients in Japan. Historical, physical, and ECG findings available on presentation can be used to stratify the risk of mortality in patients brought to Japanese emergency departments because of syncope.
