NCT04294524

Brief Summary

This is a multi-centre, registry-based study whose primary objective is to evaluate the effect of treatment for sleep apnoea syndrome (SAS) on the number of syncope/malaise episodes in a population suffering from both idiopathic, recurrent vasovagal syncope/malaises and SAS.

Outcome Measures

Primary Outcomes (1)

  • Change in 6-month syncope rate

    Day 0 refers to the initiation of sleep apnea treatment. The baseline syncope rate refers to syncope events occurring between month -6 and day 0 (S\_before). The post-treatment syncope rate refers to syncope events occurring between months +6 and +12(S\_after). The change is rates is S\_before minus S\_after.

    Month -6 to Day 0 versus Months +6 to +12

Secondary Outcomes (41)

  • Syncope/malaise dates

    Day 0 to Month 12

  • Patient-reported syncope/malaise frequency

    Baseline (Day 0)

  • Patient-reported syncope/malaise frequency

    Yearly visit (month 12)

  • Patient-reported position of syncopes/malaises

    Baseline (Day 0)

  • Patient-reported position of syncopes/malaises

    Yearly visit (month 12)

  • +36 more secondary outcomes

Other Outcomes (20)

  • The presence/absence of retrognathia

    Baseline (Day 0)

  • The presence/absence of archival palate

    Baseline (Day 0)

  • Mallampati score

    Baseline (Day 0)

  • +17 more other outcomes

Interventions

Sleep apnea treatment as decided according to routine practice. This may be Continuous positive airway pressure (CPAP) or wearing a mandibular advancement device (MAD).

Study Population

The targeted study population consists of consecutive patients with both vasovagal syncope and sleep apnea syndrome with an indication for treatment.

You may qualify if:

  • Obstructive sleep apnoea syndrome (\>15 respiratory micro awakenings per hour of sleep) with an indication for treatment
  • Recurring vasovagal syncope episodes defined as follows: at least three vasovagal syncopes during the last two years - OR- symptoms of orthostatic intolerance occurring in the last 6 months (Symptoms are triggered by orthostatism and can include malaises without loss of consciousness, asthenia, dizziness, visual disturbances, tinnitus, palpitations, headache, limitations of physical activity)

You may not qualify if:

  • Pathology that may explain syncope symptoms
  • Cardiopathy
  • Known disautonomia
  • Hypotension of known origin
  • Adrenal insufficiency
  • Thyroid disorder
  • History of sudden death in a first degree family member
