The role of tilt training in preventing recurrent syncope in patients with vasovagal syncope: a prospective and randomized study.

Full Abstract

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.
