Clinical Trial Summary

Major cardiovascular surgery is associated with postoperative cognitive decline (POCD), with a deterioration in memory, attention and speed of information processing. A multifactorial pathophysiology is presumed but this study focuses on the role of (neuro)inflammation in the development of POCD after coronary artery bypass grafting (CABG) surgery.


Clinical Trial Description

Systemic inflammation can activate the innate immune cells of the brain inducing neuroinflammation, which plays an important role in the pathogenesis of neurodegenerative disease. Major cardiovascular surgery induces a severe systemic inflammatory response.There is growing support that neuroinflammation is a pivotal factor in the development of postoperative cognitive decline (POCD) due to surgery-related systemic inflammation. Although the neuroinflammatory hypothesis is scientifically accepted, in vivo human data supporting the role of neuroinflammation in severe systemic inflammation such as major surgery are still lacking. In the last decades, several nuclear imaging tracers have been developed that can quantitatively measure microglial and astrocytic activation in vivo, by targeting the mitochondrial 18kDa translocator protein (TSPO). The investigators hypothesize that cardiac surgery induces a neuroinflammatory response and that its presence is related to acute and long term brain dysfunction postoperatively. This will be studied by pre- and postoperative PET brain imaging using a 18F-DPA-714 tracer targeting TSPO, combined with longitudinal neuropsychological examinations. Structural changes in the brain will be recorded on MRI prior to and after cardiac surgery to enable us to correct for the potentially confounding effects of neurovascular events on cognitive outcomes after CABG surgery. ;
