Syncope is experienced by a third of the population, and in the absence of cardiac pathology is most commonly of vasovagal (VVS) or unexplained origin (US). Psychiatric morbidity has been observed in up to 81% of patients with US but findings with VVS are contradictory. Little is known regarding the chronicity of their psychiatric morbidity. Objective: To determine the psychological profile of patients with recurrent syncope prior to and following diagnostic head-up tilt testing (HUT), and whether it predicts syncope recurrence. Method: Seventy-three women and 43 men (mean age=48±16.6) were recruited from all consenting patients referred for HUT. Psychological status (Psychiatric Symptom Index, Anxiety Sensitivity Index (ASI), Fear of Blood Injury Subscale) and presence of mood/anxiety disorders (Primary Care Evaluation of Mental Disorders) were evaluated 1 month prior to and 6 months following HUT. Follow-up data were collected for 83 patients (mean age=48±17.34). Results: At baseline, clinically significant levels of distress were observed in 60% of patients. Those with US (negative HUT) had a fivefold greater risk of suffering from a depressive or anxiety disorder compared to VVS (positive HUT) after controlling for significant covariates. There was no significant change in distress level over follow-up, although psychiatric morbidity dropped from 33% to 22% (P=.049). Syncope recurrence was predicted by elevations in baseline psychological distress (OR=1.544, P=.013) independently of lifetime number of syncopes. Conclusions: Patients exhibited high levels of psychological distress and psychiatric morbidity despite reassurance and education received after HUT. Improved screening for and treatment of psychological distress in these patients is critical.
Psychiatric traits in patients with vasovagal and unexplained syncope
International Journal of General Medicine
Purpose: Syncope is a common condition affecting almost one-third of the general population. The present study measures the prevalence of psychiatric traits in patients presenting with syncope (unexplained and vasovagal) and whether recurrent attacks have an impact on psychiatric profiles. Patients and methods: This is a case-control study in a tertiary hospital enrolling all patients aged ≥12 years with single or recurrent syncopal attacks. A self-reporting psychometric questionnaire (The Symptoms Checklist-90-Revised) was used to screen for depression, anxiety, somatization disorder, and phobia. Crude comparisons of average scores were done. Further, multiple logistic regression analyses were carried out to measure the impact of syncope on each psychiatric domain. The control group were matched for age, gender, and chronic illnesses with a ratio of 1:3. Results: There were 43 cases and 129 control subjects, with predominance of females (67.4%) and an average age of 33.8 years (standard deviation = 16). There were no significant differences in average scores of depression (13 vs 14.53, P = 0.31), anxiety (11.3 vs 10.4, P = 0.51), or phobia (5.4 vs 5.2, P = 0.88). However, the syncope group had a higher average score for somatization disorder (18.53 vs 13.66, P = 0.002). Binary logistic regression model showed that the association between syncope and somatization disorder was independent of competing confounders (odds ratio = 3.75, 95% confidence interval: 1.72, 8.15, P = 0.001). A sub-analysis of the case group showed that patients with multiple syncopal attacks (six or more) had higher average scores of depression, anxiety, phobia, and somatization disorder compared to those who had less than six attacks. Conclusion: Syncope was independently associated with somatization disorder traits. Further, recurrent syncope resulted in greater deterioration of patients' psychiatric profiles. Thus, taking into account the psychiatric status in the management of such patients is crucial.

Studies to assess the value of clinical symptoms to predict the head-up tilt test (HUT) outcome in patients with suspicion of vasovagal syncope have shown controversial results. We undertook this study to compare the frequency of symptoms between subjects with and without history of syncope, its association with syncopal spells in those with a history of syncope and positive or negative HUT, and to identify clinical predictors of HUT outcome. Sixty seven subjects with a history of unexplained syncope and 26 subjects without a history of syncope were interviewed using a structured questionnaire before undergoing HUT, which was performed first in a passive phase and, if negative, was repeated with pharmacological challenge using 5 mg of sublingual isosorbide. Questionnaire included the 16 symptoms most frequently reported in previous studies. Only five symptoms were reported more frequently by subjects with history of syncope in comparison with subjects without it: visual blurring, dysesthesia, sighing dyspnea, tremor in fingers, and diaphoresis. Comparison of symptom frequency between patients with history of syncope and positive or negative HUT revealed that only two were significantly different: nausea and hot flashes. However, a detailed analysis of the data indicates that only hot flashes occurring just before the syncope were more common in those with a positive HUT. Although some symptoms were found more frequently in patients with a history of syncope than in those without it, the use of a structured questionnaire in the group of patients failed to predict the outcome of the HUT.

Health-related quality of life (QoL) is reduced in patients with recurrent vasovagal (VVS) or unexplained (US) syncope. Little is known regarding these patients' QoL as pertains to their capacity to attain their life goals. Factors influencing QoL, such as sex, syncope type and illness representations have not been studied. Our objective is to examine the relationship between illness representations and QoL, as well as possible sex and syncope type differences. One hundred and Applied Research Quality Life (
Long-term outcome of patients with vasovagal syncope
American Heart Journal, 2004
Background After abnormal head-up tilt test (HUT), several trials have evaluated treatment strategies for vasovagal syncope (VVS). However, few unequivocal results have been obtained. The aim of the study was to prospectively analyze the natural history of patients with VVS who did not undergo specific treatment but received education for avoiding syncope after an abnormal HUT.

Background: Recurrent vasovagal syncope (VVS) can be a severely disabling disorder that may lead to an important deterioration of quality of life because of the severity and recurrence of episodes. This study sought to investigate the effectiveness of repeated orthostatic self-training in preventing syncope in patients with recurrent VVS.Methods: Eighty-two consecutive patients (mean age 41 ± 4 years, 37 males) with recurrent VVS episodes and positive head-up tilt testing (HUT) were enrolled in this study. The patients were then randomized (1:1) to conventional therapy or conventional therapy plus additional tilt training sessions. The patients were followed for spontaneous syncope for one year. Primary end-points were the recurrence of syncope, the number of episodes, and the interval of time to the first recurrence.Results: There were no significant differences of baseline clinical characteristics and parameters of HUT between the tilt training and control groups. The patients had 4 ± 2/year syncopal episodes prior to the HUT. The mean follow-up after randomization was 12 ± 2 months. Spontaneous syncope recurrence during follow-up was 56% (23 patients) versus 37% (15 patients) in the control and tilt training groups, respectively (P = 0.1). Time to first recurrence was also similar in both groups (70 ± 20 days vs 50 ± 15 days, P = 0.09). The frequency of recurrent syncopes was similar in all types of VVSs while the rate of episodes was significantly higher in control group in patients with vasodepressor type during follow-up period (32% vs 10%, P = 0.04). The mean number of recurrent syncope episodes was also similar in both groups (3 ± 1 vs 2 ± 1, P = 0.4).Conclusions: Tilt training was unable to influence the spontaneous syncope recurrence for recurrent VVS except for vasodepressor type.
