NCT05172362

Brief Summary

Adults with coronary artery disease (250 patients) undergoing cardiac surgery participated in the study. The aim is to investigate short-term and long-term cognitive outcomes and the patterns of organization of functional brain systems in ischemic brain damage using high-resolution electroencephalography, domain-specific assessment of cognitive status and analysis of markers of a neurovascular unit (neuron-specific enolase, brain neurotrophic factor).

Outcome Measures

Primary Outcomes (1)

  • Postoperative cognitive dysfunction

    Postoperative cognitive dysfunction (POCD) is a decline in cognitive functions following surgery and anesthesia, characterized by impairment of attention, concentration, and memory that may have long-term implications. The cognitive status assessment includes extended neuropsychological testing (the assessment of psychomotor and executive function, attention, and short-term memory from the neuropsychological test battery of the psychophysiological complex software "Status PF" (Rospatent № 2001610233).

    up to 5-7 years after surgery

Secondary Outcomes (3)

  • Basic cognitive status as measured by the Mini-Mental State Examination (MMSE) scale

    up to 5-7 years after surgery

  • Basic cognitive status as measured by the Frontal Assessment Battery (FAB)

    up to 5-7 years after surgery

  • Basic cognitive status as measured by the Montreal Cognitive Assessment (MoCA)

    up to 5-7 years after surgery
