Analysis of characteristics of transcranial Doppler combined with upright tilt test in patients with vasovagal syncope and anxiety
Objective To analyze the characteristics of transcranial Doppler combined with upright tilt test in patients with vasovagal syncope(VVS)accompanied by anxiety.Methods Ninety patients who were diagnosed and treated in our hospital from July 2021 to July 2023 were selected.The patients were divided into a VVS anxiety group,a VVS anxiety-free group,and an anxiety VVS-free group based on different symptoms,30 in each group.During the same period,30 healthy individuals underwent physical examinations were taken as a control group.The general information was collected.The head up tilt test(HUTT),hemodynamics andtranscranial Doppler(TCD)cerebral blood flow were compared.The relationship between TCD and recurrence in VVS patients with anxiety before and after treatment was analyzed.Results Among the four groups,the VVS anxiety group showed the least increase in ventricular rate,TCD blood flow velocity was decreased significantly during systole and diastole and the pulsatile index and resistance index were most increased when HUTT upright position compared to supine position(P＜0.01).After treatment,the VVS anxiety group had a high recurrence rate without TCD improvement(P＜0.05).Conclusions Patients with VVS accompanied by anxiety have abnormal autonomic nervous system function.The use of TCD for prediction of recurrence rate after treatment has a clinical value.
