[Influence of cardiopulmonary bypass on cognitive functions in patients with ischemic heart disease]
Insights
Coronary artery bypass graft surgery can cause cognitive deficits. Tracilol administration during surgery significantly reduced these deficits by inhibiting inflammation, suggesting a neuroprotective effect.
Area of Science:
- Cardiology
- Neurology
- Immunology
Context:
- Ischemic heart disease patients undergoing coronary artery bypass graft surgery (CABGS) with cardiopulmonary bypass are at risk for cognitive dysfunction.
- Neuropsychological deficits, including impaired attention, memory, and praxis, are observed post-CABGS.
Purpose:
- To evaluate the presence and severity of cognitive deficits after CABGS under cardiopulmonary bypass.
- To assess the intraoperative effect of tracilol on cognitive deficit expression.
Summary:
- Forty patients with ischemic heart disease undergoing CABGS were studied.
- Neuropsychological testing and analysis of inflammatory markers (chemokines and cytokines) were performed.
- Tracilol administration during surgery demonstrated significant neuroprotection, inhibiting systemic inflammation and preventing clinically significant cognitive deficits in the early postoperative period.
Impact:
- Tracilol exhibits a pronounced neuroprotective action, mitigating cognitive impairment following CABGS.
- This finding suggests tracilol as a potential therapeutic agent to improve neurological outcomes in cardiac surgery patients.
Abstract:
Forty patients with ischemic heart disease subjected to coronary artery bypass graft surgery (CABGS) have been studied in conditions of cardiopulmonary bypass. All the patients underwent neuropsychological testing and enzyme immunoassay of chemokines (IL-8, IP-10, MCP-1, MCP-3, MIP-1, SDF-1alpha) and cytokines (TNF-alpha and IL-10). The study aimed at evaluation of the presence and severity of cognitive deficit developing after the surgery in conditions of cardiopulmonary bypass as well as of intrasurgery effect of tracilol on its expression. On day 9 after CABGS, there was an impairment of attention, audio-speech and memory and dynamic praxis. Tracilol exerted a pronounced neuroprotective action by inhibiting systemic inflammation response. Patients on intrasurgery treatment with tracilol did not demonstrate clinically significant cognitive deficit in the early postoperative period.
