Abstract
BACKGROUND: Sudden cardiac death (SCD) is an uncommon but significant cause of death in the young. Citywide cardiac screening of school-aged children has been performed in Taipei since 1989. In this study, we investigate the efficacy of this screening method for identifying those at high risk of SCD. METHODS: This study analyzed the data from the results of cardiac screening for school-aged children in Taipei from 2003 to 2014. The cardiac screening included: Stage I, questionnaire surveys, simplified phonocardiography test and simplified electrocardiography (ECG) test; Stage II, physical examination and auscultation by a pediatric cardiologist for all children who had abnormal findings in stage I screening; Stage III, referral to a pediatric cardiologist for further examinations. Logistic regression and decision tree analyses were performed. RESULTS: A total of 566,447 students were screened, of whom 685 were identified as being at high risk of SCD. The most common causes of being at high risk of SCD included Wolff-Parkinson-White syndrome, long QT syndrome, cardiomyopathy and Marfan's syndrome. Using logistic regression analysis, the simplified ECG test was identified as being the most effective tool (odds ratio = 16.4, p < 0.001) and past history as the second most crucial factor (odds ratio = 3.95, p < 0.001) for detecting a high risk of SCD. Decision tree analysis showed that serial studies with a past history and the simplified ECG test could accurately identify those at high risk of SCD. CONCLUSIONS: Questionnaire survey and simplified electrocardiography test-based cardiovascular screening in school-aged children can identify those at high risk of SCD.
