About this study

Peripheral blood and blood following a pulmonary wedge pressure will be obtained from patients undergoing right heart catheterizations.

Read the detailed description

It is well known that left sided heart disease can lead to pulmonary hypertension via a number of proposed mechanisms. The purpose in this study is to identify biomarkers in pulmonary hypertension to further understand the pathophysiology of this disease in patients with heart disease.Patients are recruited in the cardiac catheterization lab, which are undergoing right heart catheterization as per their plan of care established by their primary cardiologist. During the procedure, we will ask the performing cardiologist to obtain a blood sample of 40-50 milliliters from the catheter that they are using during the procedure. These blood samples will be sent for analysis of biomarkers. The patient will then have an echocardiogram done 1 year from their heart catheterization.

Questions about this trial

What is this clinical trial studying?

An observational study of Diastolic Heart Failure and Pulmonary Hypertension, run by University of Toledo Health Science Campus at 1 site in United States.

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 4 inclusion and 13 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 18 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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 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?

Mortality (time frame: 1 year). 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 18 Sep 2019.
