About this study

Official title: Omics in Valvular Disease: Biomarkers of Cardiac Remodeling, Left Ventricular Function, Intensive Care Unit Outcome, and Doppler Echocardiography (OVERLOAD)

The aim of our study is to investigate the effects of impaired left ventricular remodeling on the short- and long-term prognosis in AS partecipants undergoing extracorporeal circulation during valve repair surgery and in partecipants undergoing implantation transcatheter. For the achievement of these purposes, markers obtained from will be considered cardiovascular imaging methods, such as color Doppler echocardiography and isolated biomarkers from peripheral blood and heart tissue.

Read the detailed description

Participation in this study includes, following enrollment, a visit of follow up (6/12 months) on the occasion of a concomitant medical check-up scheduled according to normal clinical practice. During these visits venous and contextual blood samples will be taken echocardiographic examination for re-evaluation of ejection fraction, as per normal practice clinic. The only variant will be the withdrawal of an additional aliquot of blood during the sampling standard blood.

All enrolled partecipants will undergo the optimal medical treatment provided by current and more recent guidelines for the treatment of heart valve disease. Joining this study will not result any modification of the current therapy, which will be established by the attending physician according to the correct one clinical practice.

What is being measured

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

  1. Description of the two serum biomarkers of mitochondrial dysfunction

    Description of the two serum biomarkers of mitochondrial dysfunction Myeloperoxidase (MPO) and Lactoferrin (LF) and the indices of myocardial performance, systolic and diastolic function of the left ventricle in patients undergoing invasive (SAVR) or non-invasive (TAVR) monitoring.

    Measured: 1 year

Secondary outcomes (2)
  1. Evaluation of the correlation between the two serum biomarkers of mitochondrial dysfunction

    The two serum biomarkers and the myocardial performance indices, of the left ventricular systolic and diastolic function , evaluated in patients undergoing invasive (SAVR) or non-invasive monitoring (TAVR).

    Measured: 6 months

  2. Evaluation of gene expression of molecular pathways involved in ventricular remodeling and correlation with echocardiographic parameters of left ventricular performance.

    The gene expression of the molecular pathways involved in ventricular remodeling and the correlation with echocardiographic parameters of left ventricular performance, will be evaluated through methods:

    • peripheral blood sampling
    • immunochemical analysis
    • evaluation of the oxidant and anti-oxidant capacity in vitro

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Stenosis, Aortic, run by Fondazione Policlinico Universitario Agostino Gemelli IRCCS at 1 site in Italy.

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 1 inclusion and 7 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: status not confirmed, as of the sponsor's last update on 20 Mar 2023. 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 Italy. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Liuzzo LG Giovanna (+39 06/30154187, giovanna.liuzzo@policlinicogemelli.it), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Description of the two serum biomarkers of mitochondrial dysfunction (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 20 Mar 2023.
