Correlation of SOZO BIS Measures With CardioMEMS PA Pressure

July 5, 2019 updated by: ImpediMed Limited

Correlation of Bioimpedance Measurements From the SOZO Device With Pulmonary Arterial Pressure Measurements From the CardioMEMS HF System

This study aims to establish the degree to which change in the ratio of ECF to TBW measured using the SOZO BIS device correlates with change in end-expiratory end-diastolic PAP measured using the CardioMEMS HF System (St. Jude Medical).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a prospective, single-arm, observational, non-randomized clinical study that will enroll patients with heart failure who have had a CardioMEMS™ device implanted to monitor their diastolic pulmonary artery pressure. The study will recruit and enroll thirty participants. Participants will be monitored daily at home for a period of 30 days. Each day, the patient's diastolic pulmonary artery pressure will be measured by CardioMEMS™ and the ImpediMed's BIS technology. Participant's weight will also be taken each day.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Single-arm
All subjects enrolled will undergo measurements with the SOZO device daily for 30 days.
Device: SOZO
The SOZO device is a bioimpedance spectroscopy device that measures bioimpedance parameters.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in the ratio of whole body ECF/TBW measured using the SOZO BIS device
Time Frame: From baseline through study completion, an average of 30 days
Changes of body fluid levels in heart failure patients
From baseline through study completion, an average of 30 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in the ratio of thoracic ECF/TBW
Time Frame: From baseline through study completion, an average of 30 days
Changes of thoracic fluid levels in heart failure patients
From baseline through study completion, an average of 30 days
Change in the ratio of lower extremity ECF/TBW
Time Frame: From baseline through study completion, an average of 30 days
Changes of lower limb fluid levels in heart failure patients
From baseline through study completion, an average of 30 days

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
