Assessing Neuroinflammation and Oxidative Stress After Cardiac Surgery: Unveiling Molecular Dynamics and Clinical Outcomes

The prospective observational study delves into the complex relationship between neuroinflammation and oxidative stress in post-cardiac surgery complications, focusing on postoperative cognitive dysfunction.

Study Overview

Status

Status

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

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

The prospective observational study meticulously examines the interplay between neuroinflammation and oxidative stress in the realm of post-cardiac surgery complications, specifically targeting postoperative cognitive dysfunction. Its primary objective is to comprehensively assess the sustained influence of these intricate processes on cognitive function and overall well-being, extending beyond the immediate aftermath of surgery. The research endeavors to probe deeply into the molecular mechanisms and clinical ramifications associated with neuroinflammation and oxidative stress, centering on their pivotal role in shaping the onset and trajectory of postoperative cognitive dysfunction.

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.
Experimental group 1
Patients scheduled for elective cardiac surgery, such as coronary artery bypass grafting (CABG) or valve replacement, involving extracorporeal circulation (ECC) with a duration less than 60 minutes.
Other: extracorporeal circulation
extracorporeal circulation during cardiosurgical operation
Experimental group 2
Patients undergoing scheduled cardiac procedures, including coronary artery bypass grafting (CABG) or valve replacement, requiring extracorporeal circulation (ECC) for more than 60 minutes.
Other: extracorporeal circulation
extracorporeal circulation during cardiosurgical operation
Control group:
Patients scheduled for cardiac surgical procedures such as coronary artery bypass grafting (CABG) without extracorporeal circulation, and for carotid endarterectomy in neurologically asymptomatic patients prior to the procedure.

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
Number and type of early complications after surgery
Time Frame: 1 month
Estimating of postoperative complications
1 month
Number and type of postoperative complications
Time Frame: 6 months
Estimating of postoperative complications
6 months

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
Estimating biochemical parameters
Time Frame: 1 hour
Pro-inflammatory interleukins parameters (e.g. IL-8, IL-6, MIP-1a, MMP-2, MMP-9, SIRT 1, SIRT 2)

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 Major Dates

Study Start (Estimated)

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.
April 30, 2024

Primary Completion (Estimated)

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.

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
