- Abstract
Objective: The aim of the study was to define predictors of syncope recurrence in children and adolescents with vasovagal syncope and to determine the value of tilt test. Methods: A retrospective observational study performed of prospective cohort of 150 patients aged between 8-18 years who were referred to our clinic because of fainting or who underwent tilt test with the pre-diagnosis of vasovagal syncope. The progress updated by telephone or face-to-face interview. Unpaired t-test, Mann-Whitney U test used for normal and non-normal distributed variables. Logistic regression analysis was used to determine the predictors of recurrence. Results: Tilt test was positive in 97 and negative in 53 patients. Forty-eight patients had mixed, 34 had vasodepressor and 15 had cardioinhibi-tory type syncope. Recurrence found significantly higher in patients who had syncope in the first 20 minutes of the test (p=0.012). The number of the episodes decreased after the test; 3.86±4.75vs 0.73±0.44, pcO.OOl). The recurrence was higher in patients who had more than 4 episodes. The recurrence was similar between positive and negative tilt groups. Age of syncope (OR 1.01, 95% CI 1.002, p=0.027) positive family history (OR 4.47, 95% C11.071-1.389, p=0.001) and the number of previous syncopal episodes (OR 1.22, 95% CI 1.882-10.623, p=0.003) were identified as risk factors for recurrence of vasovagal syncope. Conclusion: Age of syncope, positive family history and the number of previous syncopes are the predictors of recurrence of vasovagal syn-cope in children and adolescents. The number of recurrent episodes decreased after the test independently from Head-up tilt test results.
