Analysis of risk factors for vasovagal syncope in children

  Objective  To analyze the related factors of the onset of vasovagal syncope (VVS) in children, and to provide basis for the early prevention, early diagnosis and early treatment of VVS.  Methods  A total of 126 children with syncope admitted to Department of Pediatric Cardiology, Second Hospital of Lanzhou University from October 2018 to September 2019 were invited in the study. Totally 73 cases of children diagnosed with VVS by HUTT were selected as VVS group, and 53 HUTT-negative children were selected as control group. Related factors were retrospectively investigated, and risk factors for VVS were analyzed by univariate and multivariate regression.  Results  The VVS group showed statistically significant difference in age distribution with the control group (χ2=19.22, P<0.05). The VVS group showed statistically significant differences of proportion in family history, syncope history, prolonged standing, electrocardiogram abnormalities, and vitamin D deficiency (43.84%, 31.51%, 47.95%, 34.25%, 30.14%) compared with the control group (15.09%, 13.21%, 20.75%, 15.09%, 9.43%) (χ2=11.71, 5.67, 9.79, 5.83, 7.82, P<0.05). Multivariate Logistic regression analysis showed that age and family historywere risk factors for VVS(χ2=3.13, 11.06, P<0.05).  Conclusion  Age and family history may be risk factors for the onset of VVS. Active attention should be paid to the high-risk factors of child patient, early identification and diagnosis can prevent the occurrence and development of VVS in children.
