About this study

Official title: Brain Protection and Neurological Prognosis in Patients With Heart Valve Disease Undergoing Cardiopulmonary Bypass Operation

The purpose of this study is to clarify the changes of neurocognitive function of patients undergoing cardiac valve disease before and after surgical treatment under cardiopulmonary bypass operation, and to predict the neurological prognosis of such patients through combined imaging technology, so as to improve and avoid the occurrence of postoperative neurological dysfunction in such patients.

Read the detailed description

This study focuses on brain protection in patients with heart disease. The preoperative brain imaging and consciousness and cognition evaluation results, intraoperative brain monitoring indicators, adverse events of neurological function, brain imaging and consciousness and cognition evaluation results during the postoperative and follow-up periods were recorded. At the same time, serum markers related to perioperative neurological function were obtained to explore the relevant factors affecting neurocognitive function during the perioperative period. The research objectives to investigate the perioperative changes of neurocognitive function in patients undergoing heart valve surgery under cardiopulmonary bypass and the related factors affecting the prognosis of neurocognitive function.

What is being measured

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

  1. Change of brain volume before and after operation

    The change of brain volume (mm3) are evaluated by structural 3DT1 weighted MRI. Freesurfer software is used to get the measured value of the volume.

    Measured: before operation; 7-10 Days after operation; 1 month; 6-12months

  2. Change of brain function connectivity before and after operation

    The change of brain functional connectivity intensity are evaluated by rest stage functional MRI. DPABI software based on MATLAB is used to get the measured the matrix value of functional connectivity.

    Measured: before operation; 7-10 Days after operation; 1 month; 6-12months

Secondary outcomes (10)
  1. Change of brain evaluate basic cognition before and after operation

    The change of basic cognition is evaluated by Mini-mental State Examination. The minimum value is 0 , and the maximum value is 30. The higher scores mean a better outcome.

    Measured: before operation; 7-10 Days after operation; 1 month; 6-12months

  2. Change of executive functions before and after operation evaluated by Trail-Making Test Part A

    The change of executive functions are first evaluated by Trail-Making Test Part A test. The minimum value is 0 , and the maximum value is 30. This test has no clear maximum and minimum values. If the test completion time exceeds 79 seconds, it means the outcome is abnormal. The higher scores mean a worse outcome.

    Measured: before operation; 7-10 Days after operation; 1 month; 6-12months

  3. Change of executive functions before and after operation evaluated by Digit Symbol Coding score

    The change of executive functions are second evaluated by Digit Symbol Coding score. The minimum value is 0 , and the maximum value is not clear. The normal range of results is 56.53 ± 20.17. The higher scores mean a better outcome.

    Measured: before operation; 7-10 Days after operation; 1 month; 6-12months

  4. Change of working memory before and after operation evaluated by Forward Digit Span

    The change of working memory is first evaluated by Forward Digit Span. The minimum value is 0 , and the maximum value is not clear. The normal range of results is 7.75±1.47. The higher scores mean a better outcome.

    Measured: before operation; 7-10 Days after operation; 1 month; 6-12months

  5. Change of working memory before and after operation evaluated by Backward Digit Span

    The change of working memory is second evaluated by Backward Digit Span. The minimum value is 0 , and the maximum value is not clear. The normal range of results is 5.36±1.91. The higher scores mean a better outcome.

    Measured: before operation; 7-10 Days after operation; 1 month; 6-12months

  6. Change of language ability before and after operation

    The change of language ability is evaluated by Chinese Version Verbal Fluency Test. The minimum value is 0 , and the maximum value is not clear. The normal range of results is 19.43±4.81. The higher scores mean a better outcome.

    Measured: before operation; 7-10 Days after operation; 1 month; 6-12months

  7. Preliminary judge whether delirium occurs after operation

    Delirium is preliminary evaluate using confusion assessment method(CAM). The minimum value is 0 , and the maximum value is 4. The higher scores mean a worse outcome.

    Measured: Witnin 96 hours after operation

  8. Fine judge whether delirium occurs after operation

    Delirium is fine evaluated using Delirium Rating Scale(DRS-R-98). The minimum value is 0 , and the maximum value is 39. The higher scores mean a worse outcome.

    Measured: Witnin 96 hours after operation

  9. Change of plasma marker concentration before and after operation

    The change of plasma marker concentration is evaluated by neurofilament light chain(NFL) protein extracted from plasma.

    Measured: before operation; immediately after operation; 1,2,3,4 Days after operation

  10. Change of serum marker concentration before and after operation

    The change of serum marker concentration is evaluated by inflammatory cytokine.

    Measured: before operation; immediately after operation; 1,2,3,4 Days after operation

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 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 14 Sep 2022. 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 China. 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 Nengrui Guo (0086-17635599999, 657040251@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change of brain volume before and after operation (time frame: before operation; 7-10 Days after operation; 1 month; 6-12months). The study lists 2 primary outcomes in all. 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?
