A consecutive series of 67 patients with suspected VVS underwent HUT: 45 patients had a positive HUT, 22 negative. They were evaluated by means of observer- and self-rated measures.
Of the total sample, 95.5 % had at least one Diagnostic and Statistical Manual of Mental Disorders diagnosis or one psychosomatic syndrome, such as specific and social phobias, illness denial and demoralization. Comparing VVS and US patients, no statistical differences on diagnoses' frequencies were found. However, the US group had significantly poorer health habits, lower levels of well-being and higher psychological distress. They also reported to be more anxious, depressed and hostile. VVS patients were significantly more blood and social phobic than US patients.
Despite similar and remarkable observer-rated psychopathology, US patients reported higher self-perceived psychological distress than VVS patients. Psychological evaluation of patients undergoing HUT should incorporate both clinical and subclinical methods to better address syncope management.
