Last Updated: 2017-04-06

Results Overview

Collect short and long term clinical data on safety of the remede system implanted in daily practice. This outcome measure was intended to be collected up to 5 years, but at time of early study termination the data were only monitored until 24 months for 1 patient.

Recruitment status

TERMINATED

Target enrollment

31 participants

Primary outcome timeframe

From implant up to 5 years (collected until 24 month FU)

Measure
CSA Patients NOT Implanted With remedē System
For all patients diagnosed with CSA who will not move forward with remedē® system therapy, the intention is to obtain information on their alternate therapy, if any, and safety information, including all cause mortality and all cause hospitalizations during phone calls at 6, 12 and 24 months after enrollment.
CSA Patients With remedē System
For all patients diagnosed with CSA and referred for implant / or have already been implanted with remedē system, information from the implant procedure will be collected. Patients will be asked to complete quality of life questionnaires at baseline and during follow-up visits. Patients will be evaluated at the time of therapy activation which may be followed by one or more titration visits. Patient follow-ups will be programmed at 6 and 12 months, and yearly, up to 5 years post-implant, until the last patients reach their 2-year follow-up. Echocardiogram for patients with reduced ejection fraction (≤ 45%) and follow-up respiratory polygraphy are considered standard of care, however, to ensure sufficient data, related to the study objectives, are being collected, baseline and 12-months echocardiogram for a subgroup of patients and respiratory polygraphy at 12-month follow-up for all patients must be done when participating in this study:

PRIMARY outcome

Timeframe: From implant up to 5 years (collected until 24 month FU)

Population: Viewing the limited amount of data at early study termination, the data should be interpreted with caution.

Collect short and long term clinical data on safety of the remede system implanted in daily practice. This outcome measure was intended to be collected up to 5 years, but at time of early study termination the data were only monitored until 24 months for 1 patient.

SECONDARY outcome

Timeframe: 12 months post-implant

Population: A complete dataset is only available for 1 patient and due to confidentiality reasons for this 1 patient we prefer not to present this data.

Evaluate changes in sleep study results at 12 months compared to baseline

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Up to 5 years post-implant

Population: No data available on Quality of Life questionnaires; no patient completed the questionnaires at baseline AND at the 12M/24M follow-up at the time of premature study stop.

Evaluate impact on Quality of Life by using a general questionnaire, a sleep-specific questionnaire and a questionnaire specific for heart failure patients

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 12 months post implant

Population: No data available; no patient had completed a 12 months echo prior to the premature study stop

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Up to 2 years (collected until 6M FU)

Population: No conclusion can be drawn on all-cause mortality and all-cause hospitalization rates for this group of patients;only 3 subjects diagnosed with CSA (not implanted) reached the 6M FU at the time of study termination. No deaths and/or hospitalizations had been reported in this subject group at the time of study termination.No 12M data is available.

Collect site reported safety data on all patients diagnosed with central sleep apnea and not treated with the remede system
