Abstract:
Objective To explore the predictive value of orthostatic intolerance( OI) symptoms in children and adolescents to the head-up tilt test( HUTT) results. Methods A total of 274 children or adoles-cents complaining with the following symptoms were chosen:unexplained syncope,dizziness,headache,chest tightness,chest pain,sigh,and so on. The 274 cases included 141 males and 133 females aging from 5 to 18 years old with a mean age of (11. 8 ± 2. 7) years. All the cases in this study came from the syncope special-ized clinic or inpatient department of the Second Xiangya Hospital,Central South University,from July 2016 to March 2017. All the patients had been asked in detail about the history, physical examination, routine 12-lead electrocardiogram,chest X-ray,echocardiogram,electroencephalogram,head computer tomography or magnetic resonance imaging,blood and a series of checks to exclude organic heart,brain,lung diseases. Each patient was asked to finish OI questionnaire and HUTT. Results All 274 patients were divided into HUTT negative group(n=151) and HUTT positive group(n=123). Dizziness(65. 3％) was the most common OI symptom,followed by syncope(50. 7％),blurred vision or amaurosis(45. 6％) and fatigue(43. 4％). There were significant differences in the prevalence of palpitation,headache,profuse perspiration,blurred vision or amaurosis,chest tightness,dizziness,gastrointestinal symptoms( nausea,vomiting,abdominal pain,abdominal distension) and syncope between HUTT positive and HUTT negative groups ( P<0. 05 ) . According to the multivariate Logistic regression analysis,these eight OI symptoms could affect the results of HUTT to some extent(odds ratio>1). Conclusion The symptoms of palpitation,headache,profuse perspiration,blurred vi-sion,chest discomfort,dizziness,gastrointestinal symptoms( nausea,vomiting,abdominal pain,abdominal dis-tension) and syncope can impact the positive results of HUTT.
