Abstract:
Objective:To analyze the changes in serum levels of neurofilament light chain(NFL),binding protein S100 β(S100 β),and C-reactive protein(CRP)in patients with cognitive impairment after cardiac surgery,and to analyze the correlation between these indicators and patient prognosis.Methods:124 patients with heart disease who underwent surgical treatment from January 2022 to January 2025 were selected.One week after surgery,the patients were evaluated using the Montreal Cognitive Assessment Scale(MoCA).60 patients with MoCA scores<26 were divided into the cognitive impairment group,and 64 patients with MoCA scores ≥ 26 were divided into the non cognitive impairment group.Compare the general information of two groups,including changes in serum NFL,S100 β,and CRP levels before and after surgery.Using logistic regression to analyze the influencing factors of cognitive impairment after cardiac surgery.Following a 4-month postoperative follow-up,the cognitive impairment group was assessed using the MoCA score.Patients with a MoCA score<26 were categorized as having a poor prognosis,while the remaining patients were classified as having a good prognosis.The NfL,S100β,and CRP levels in both groups were compared,and the ROC curve was used to evaluate the predictive value of serum NFL,S100β,and CRP for poor prognosis in patients with postoperative cognitive impairment.Results:There was no significant difference in gender,BMI,education level,comorbidities(hypertension,diabetes),disease type,ASA classification,intraoperative blood loss,intraoperative fluid replacement,and cardiopulmonary bypass time between cognitive impairment group and non-cognitive impairment group(P>0.05).The cognitive impairment group had a higher incidence of age,anesthesia maintenance time during surgery,no analgesia after operation and agitation during awakening than the non-cognitive impairment group(P<0.05);There was no significant difference in the levels of serum NFL,S100β,and CRP between the two groups of patients before surgery(P>0.05).On postoperative day 3,the levels of serum NFL,S100β,and CRP increased in both groups,with the cognitive impairment group being higher than the non cognitive impairment group(P<0.05);Using cognitive impairment(occurrence=1,no occurrence=0)as the dependent variable,logistic regression analysis showed that age,intraoperative anesthesia maintenance time,agitation during the recovery period,postoperative 3-day NFL,S100 β,CRP were independent influencing factors of cognitive impairment after cardiac surgery(P<0.05);The serum levels of NFL,S100β,and CRP in the good prognosis group and poor prognosis group were higher than those before surgery,and the NFL,S100 β,and CRP levels in the poor prognosis group were higher than those in the good prognosis group before and after surgery(P<0.05);Using poor prognosis as positive samples and good prognosis as negative samples,a ROC curve was plotted.The results showed that the sensitivity and specificity of the combined prediction of three indicators before and after surgery for poor prognosis of cognitive impairment in cardiac surgery were higher than those of a single indicator(P<0.05).Conclusion:The serum levels of NFL,S100β,and CRP are significantly elevated in patients with cognitive impairment after cardiac surgery,and the early postoperative elevation of NFL,S100β,and CRP is a contributing factor to the occurrence of cognitive impairment.Preoperative and early postoperative detection of these indicators can predict the prognosis of patients with cognitive impairment after cardiac surgery.
