BACKGROUND:We aimed to observe the dynamic changes in glucose metabolic reprogramming-related parameters and their ability to predict neurological prognosis and all-cause mortality in cardiac arrest patients after the restoration of spontaneous circulation(ROSC). METHODS:Adult cardiac arrest patients after ROSC who were admitted to the emergency or cardiac intensive care unit of the First Affiliated Hospital of Dalian Medical University from August 1,2017,to May 30,2021,were enrolled.According to 28-day survival,the patients were divided into a non-survival group(n=82)and a survival group(n=38).Healthy adult volunteers(n=40)of similar ages and sexes were selected as controls.The serum levels of glucose metabolic reprogramming-related parameters(lactate dehydrogenase[LDH],lactate and pyruvate),neuron-specific enolase(NSE)and interleukin 6(IL-6)were measured on days 1,3,and 7 after ROSC.The Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ)score and Sequential Organ Failure Assessment(SOFA)score were calculated.The Cerebral Performance Category(CPC)score was recorded on day 28 after ROSC. RESULTS:Following ROSC,the serum LDH(607.0 U/L vs.286.5 U/L),lactate(5.0 mmol/L vs.2.0 mmol/L),pyruvate(178.0 μmol/L vs.70.9 μmol/L),and lactate/pyruvate ratio(34.1 vs.22.1)significantly increased and were higher in the non-survivors than in the survivors on admission(all P＜0.05).Moreover,the serum LDH,pyruvate,IL-6,APACHE Ⅱ score,and SOFA score on days 1,3 and 7 after ROSC were significantly associated with 28-day poor neurological prognosis and 28-day all-cause mortality(all P＜0.05).The serum LDH concentration on day 1 after ROSC had an area under the receiver operating characteristic curve(AUC)of 0.904[95％confidence interval[95％CI]:0.851-0.957])with 96.8％specificity for predicting 28-day neurological prognosis and an AUC of 0.950(95％CI:0.911-0.989)with 94.7％specificity for predicting 28-day all-cause mortality,which was the highest among the glucose metabolic reprogramming-related parameters tested. CONCLUSION:Serum parameters related to glucose metabolic reprogramming were significantly increased after ROSC.Increased serum LDH and pyruvate levels,and lactate/pyruvate ratio may be associated with 28-day poor neurological prognosis and all-cause mortality after ROSC,and the predictive efficacy of LDH during the first week was superior to others.
