COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

The Cardiac Interventions, Surgery and Cognitive Outcome (CISCO) Study
Scientific title
The prospective observational CISCO (Cardiac Interventions, Surgery and Cognitive Outcome) study will document the preoperative neuropsychological status of patients presenting for coronary angiography (CA) and relate this to cognitive outcomes over the succeeding three months, taking into account their management (medical; Percutaneous Coronary Intervention (PCI); or Coronary Artery Bypass Graft (CABG) surgery).

Description of intervention(s) / exposure
To test whether Mild Cognitive Impairment (MCI) prior to CA is associated with an increased risk of PPCD (Post Procedural Cognitive Dysfunction) and to compare cognitive changes between management techniques (medical; PCI; CABG surgery). Patients will complete a battery of conventional and computerised neuropsychological tests preoperatively. They will then complete the computerised test battery at 24 hours, 6 days and 3 months post intervention to identify changes in cognitive function. The tests takes about 1 hour to complete. Quality of Life (QoL), mood, Activities of Daily Living (ADL) and Clinical Dementia Rating (CDR) will be assessed preoperatively and at 3 months post intervention.

Eligibility
Key inclusion criteria
Scheduled for elective CA who do not have neurological (as opposed to neuropsychological) deficit or any contraindication to undergoing neuropsychological testing, and have given informed consent. The patients must reside in accessible proximity to the hospital to enable investigators to administer neuropsychological testing at home.
Minimum age
50 Years
Maximum age
Not stated
Gender
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
i. Pre-existing neurological or clinically evident neurovascular disease (e.g. TIA, stroke);ii. Dementia: a score less than 26 on the Mini Mental State Examination (MMSE) or CDR > 1;iii. Anticipated difficulty with neuropsychological assessment such as: English not being the prime language; blindness; deafness;iv. Geographical remoteness or medical co-morbidity that may lead to complications and loss to follow-up.

Summary
Brief summary
The CISCO (Cardiac Interventions, Surgery and Cognitive Outcome) Study is a prospective observational cohort study of the preoperative neuropsychological status of patients presenting for CA (Coronary Angiography) and the relationship of this state with cognitive outcomes following medical, PCI (Percutaneous Coronary Intervention) or CABG (Coronary Artery Bypass Graft) surgery management of their disease.
