About this study

Official title: The Efficacy of PAP Therapy on Reducing AF Recurrence in Patients With Morbidity of OSA: a Clinical Randomized Control Trial

This study aims to test the effectiveness of positive airway pressure therapy on reducing clinical failure after rhythm control treatment and restoring with regular heart beat in atrial fibrillation patients with obstructive sleep apnea.

Read the detailed description

This study aims to test the effectiveness of positive airway pressure therapy on reducing clinical failure after rhythm control treatment and restoring with regular heart beat in atrial fibrillation patients with obstructive sleep apnea. The study is designed as a multi-center randomized control trial, which plans to recruit 129 atrial fibrillation patients with obstructive sleep apnea (86 in the intervention group with atrial fibrillation standard care and positive airway pressure therapy, 43 in the control group with atrial fibrillation standard care but no positive airway pressure therapy). The subjects will in total visit the hospital 4 times during their 6 months follow-up period, at baseline, 1st, 3rd, and 6th month. Subjects will undergo questionnaire surveys and medical examinations at each visit. The primary objective is to compare after 6months, the clinical failure rate between the group with positive airway pressure therapy and the group with no positive airway pressure therapy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PAP therapy with telemonitoringDevice

    This study intends to investigate effect of PAP therapy on reducing AF recurrence rate in the patients in co-morbidity of OSA. The study will use 2 investigational devices: Philips DreamStation and Philips EncoreAnywhere. Philips DreamStation is used as the PAP therapy device to provide PAP therapy on the study subjects; Philips EncoreAnywhere is used as a telemonitoring service to provide monitoring by physicians that ensure good adherence to PAP. In addition, subjects in the intervention group will also receive AFib standard management and OSA general care.

  • AF standard management and OSA general careOther

    Subjects in the control group will receive AF standard management and OSA general care. The treatment, medical care, and AF management for the subjects will be performed at the study hospitals following the newly updated Chinese AF management guideline 'Current knowledge and management recommendations of atrial fibrillation: 2018'.All subjects including the intervention group and the control group will receive the education materials to understand the disease, risk, and management of OSA. All subjects will also receive the general intervention for OSA, including suggestions for body weight control, smoking cessation, alcohol limiting, lateral position sleep, etc.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of participants with documented AFib recurrence

    The primary outcome is number of participants with documented clinical failure. The documented clinical failure is defined as fulfilling any one of the following situations: documented recurrence of atrial fibrillation, atrial flutter or atrial tachycardia (lasting more than 30 seconds), new prescription of antiarrhythmic drugs (class I or III), repeat ablation (for patients underwent ablation at baseline) or new ablation (for patients used antiarrhythmic drugs for rhythm control at baseline).

    Measured: From baseline to the event occurs, up to 6 months.

Secondary outcomes (5)
  1. Change from baseline in atrial fibrillation burden at 6 months

    Atrial fibrillation burden from baseline to 6 months will be tested by single-lead ECG, calculated by total time in AF divided by the total time in sinus rhythm

    Measured: Baseline, the 6th month.

  2. Changes from baseline in self-rated AF symptoms at 1 month, 3 months and 6 months.

    Self-rated AF symptoms will be tested with the modified EHRA Symptom Scale

    Measured: Baseline, the 1st month, 3rd month and 6th month.

  3. Changes from baseline in quality of life at 3 months and 6 months.

    Quality of life will be tested with EQ-5D questionnaire

    Measured: Baseline, the 3rd month and 6th month.

  4. Changes from baseline in daytime sleepiness at 1 month, 3 months and 6 months.

    Sleepiness will be tested with the Epworth Sleepiness Scale (ESS).

    Measured: The 1st month, 3rd month and 6th month.

  5. Other cardiovascular events

    Other cardiovascular events will be diagnosed and recorded by physicians.

    Measured: From baseline to the event occurs, up to 6 months.

The record lists 2 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: Sponsor and investigators aligned to terminate this study.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of participants with documented AFib recurrence (time frame: From baseline to the event occurs, up to 6 months.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04519489, which also lists 14 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Sep 2025.
