Optimizing HFrEF Patients Using BaroStim and CardioMems
What this study is about
The goal of this study is to utilize CardioMems (measurement of pulmonary artery diastolic pressure) to assess BaroStim. At the time of CardioMems insertion, patients will be screened for candidacy to receive a BaroStim device. Patients will be followed for 3 months after the CardioMems insertion before undergoing insertion of a Barostim.
View original scientific description
The goal of this study is to utilize CardioMems (measurement of pulmonary artery diastolic pressure) to assess BaroStim. At the time of CardioMems insertion, patients will be screened for candidacy to receive a BaroStim device. Patients will be followed for 3 months after the CardioMems insertion before undergoing insertion of a Barostim. Patients who have undergone a CardioMems, will be eligible for enrollment after 3 months of medication management and optimization. Patients will be followed for 1 year after insertion of Barostim.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Provision of signed and dated informed consent form
- Stated willingness to comply with all study procedures and availability for the duration of the study
- Male or female, ages 18-80 years
- Diagnosed with NYHA Class III Heart Failure with LVEF\<35%
- Able to tolerate oral medications for guideline directed medical therapy titration period
- Have undergone insertion of CardioMems and BaroStim devices per standard of care.
- It is a standard of care to recommend that females of reproductive potential use highly effective contraception, because of the teratogenic potential of many medications used to treat HFrEF. In addition, withdrawal of GDMT during pregnancy may reverse the positive remodeling and lead to life threatening worsening of heart failure. Women of child-bearing age need to agree to use such a method during study participation and indefinitely after the end of the study.
Exclusion criteria
- Individuals ineligible for either CardioMems or BaroStim devices.
- NT-proBNP \>1600 mg/dL
- Indicated for CRT-D device (left bundle branch block)
- Initial 6-minute walk test distance less than 140 m
- Left ventricular assist device (LVAD)
- History of carotid vascular procedure (carotid endarterectomy)
- Pregnancy or lactation
- Known allergic reactions to components of the BaroStim or CardioMems insertion or guideline directed medical therapy for heart failure
- Febrile illness within 30 days of study enrollment
- Treatment with another investigational drug or other intervention within 1 year
- Current smoker or tobacco use within 1 year
- Enrolled in any other CVRx funded study, including investigator-initiated research, registries, or other pre- or post-market studies.
- Vulnerable individuals as outlined below
Where
- Riverhead, New York
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
