About this study

Official title: Characterization of Factors Influencing the Occurrence of Cognitive Decline in Patients With Coronary Artery Disease and Undergoing Cardiac Surgery and Coronary Angioplasty

The real impact of cardiac surgery and coronary angioplasty remains to be clarified and, where appropriate, the influencing factors in a way beneficial or deleterious remain to be identified.

The identification of such factors could make even faster screening, prevention and therefore open therapeutic prospects for those patients.

The objective of the study is to constitute a prospective cohort to assess the occurrence of cognitive decline after cardiac surgery (200 patients) and coronary angioplasty (200 patients) using the scale Dementia rating scale (DRS) of Mattis. In addition, the investigators will identify factors that influence positively or negatively, the occurrence of such a cognitive decline. The study based on a systematic monitoring of clinical, biological, imaging and pharmacological factors and, to correlate the respective influence of these factors on the incidence of cognitive decline.

Read the detailed description

Cardiovascular invasive interventions (surgery and angioplasty) save thousands of lives every year, but questions remain about the neurological complications and in particular cognitive deficit. Indeed, cardiac surgery has been associated with cognitive decline in 50 to 70% of patients in the first postoperative week and in 20 to 40% of patients 6 months to one year after surgery.

The study will be based on a prospective monitoring during 1 year of a cohort of 400 patients who will receive either a cardiac surgery or coronary angioplasty. At inclusion, will be collected medical history, risk factors, treatment history, clinical and etiological data (imaging, cardiac and vascular balance).

The results of routine tests performed complementary to hospitalization will be recorded (echo-doppler vessels of the neck, cardiac ultrasound trans-thoracic and/or transesophageal a holter cardiac).

In recruiting, we will apply a method of matching based on age (on 5 years) between 2 groups in order to compare 2 homogeneous groups.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Cardiac surgeryProcedure or surgery

    A study-certified cardiothoracic surgeon must deem a patient, who otherwise fulfills all inclusion and exclusion criteria for any cardiac surgery (conventional, off-pump cardiac surgery). The procedure must be performed as soon as possible.

Study groups in NCT00946959
Study groupRoleWhat they receive
cardiac surgeryExperimentalThis arm will include patients older than 18 years and candidate to cardiac surgery.
Receives: Procedure: Cardiac surgery
cardiac angiographyNo interventionPatients older than 18 years who undergo coronary angiogram. This arm will include patients with coronary revascularization and patients without coronary revascularization.

What is being measured

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

  1. Compare cognitive disorders using the scale Dementia rating scale (DRS) of Mattis in 2 groups

    Measured: Before intervention and 12 month after intervention

Secondary outcomes (3)
  1. Blood biomarkers: inflammation, coagulation, protein

    Measured: Before intervention, 3 weeks (no biology), 6 months (no MRI and biology) and 12 month after intervention (no biology)

  2. Neuropsychological evaluation: global cognitive function using MMSE, memory, attention

    Measured: Before intervention, 3 weeks (no biology), 6 months (no MRI and biology) and 12 month after intervention (no biology)

  3. Imaging parameters (MRI): abnormalities of white matter, ischemic lesions, hippocampus volume

    Measured: Before intervention, 3 weeks (no biology), 6 months (no MRI and biology) and 12 month after intervention (no biology)

Questions about this trial

What is this clinical trial studying?

A study testing Cardiac surgery in people with Coronary Artery Disease, run by University Hospital, Lille at 1 site in France.

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 2 inclusion and 1 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 9 Nov 2016. 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 France. 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?

Compare cognitive disorders using the scale Dementia rating scale (DRS) of Mattis in 2 groups (time frame: Before intervention and 12 month after intervention). 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 9 Nov 2016.
