Trial summary

Heart Failure (HF) is one of the most frequent diagnoses upon hospitalization and is a major cause of death. Cardiac resynchronization therapy (CRT) using an implantable device for synchronous bi-ventricular stimulation leads to improvement of hemodynamic parameters, physical capacity and quality of life.

About this study

Heart Failure (HF) is one of the most frequent diagnoses upon hospitalization and is a major cause of death. Cardiac resynchronization therapy (CRT) using an implantable device for synchronous bi-ventricular stimulation leads to improvement of hemodynamic parameters, physical capacity and quality of life. A continuous measurement of the left-ventricular volume would provide information about heart performance and could be used for both heart failure monitoring and optimization of CRT-therapy.

What is being measured

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

  1. Intra-indivudual correlation coefficient r between stroke volume (SV) and stroke impedance (SZ).

    SV will be assessed using Echo Doppler Ao-VTI (Aortic velocity time integral). SZ will be measured in parallel using intracardiac impedance measurement. The parameters will be assessed during a sequential measurement being conducted in month 2 of the observational period. Hemodynamic changes will be actively provoked using the CRT-D system for overdrive-pacing.

    Measured: Month 2

Secondary outcomes (1)
  1. Intra-individual correlation coefficient r between left-ventricular end-systolic volume (LVESV) and left-ventricular end-systolic impedance (LVESZ).

    LVESV will be assessed using echo Biplane Simpson's method. LVESZ will be measured using the intracardiac impedance measurement. The parameters will be assessed during a sequential measurement being conducted in month 2 of the observational period. Hemodynamic changes will be actively provoked using the CRT-D system for overdrive-pacing.

    Measured: Month 2

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Intracardiac Impedance Measurement Algorithm (integrated in CRT-D device) in people with Heart Failure, run by Biotronik SE & Co. KG at 22 sites in 5 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Jul 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 22 sites in Germany, Denmark, Netherlands, Italy, Switzerland. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Intra-indivudual correlation coefficient r between stroke volume (SV) and stroke impedance (SZ). (time frame: Month 2). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 15 Jul 2015.
