Objective To explore the predictive value of neutrophil to lymphocyte ratio(NLR)for nosocomial cardiogenic shock(CS)after acute myocardial infarction(AMI).Methods The clinical data of 100 patients with AMI in Longyan People's Hospital from January 2021 to October 2023 were retrospectively analyzed.The 55 patients with in-hospital CS after infarction were included in shock group,and 45 patients without CS were included in non-shock group.According to shock index(SI),the patients in shock group were divided into mild shock group(30 cases)and moderate-severe shock group(25 cases).The levels of neutrophil count(NEU)and lymphocyte count(LYM)were detected using fully automated blood cell analyzer,and NLR was calculated.The levels of above indicators in each group were compared.The receiver operator characteristic curve(ROC curve)was drawn and area under ROC curve(AUC)was calculated to examine the predictive value of NLR for in-hospital CS after AMI.Results The levels of NEU and NLR in shock group were higher than those in non-shock group,while the level of LYM was lower than that in non-shock group[NEU(×109/L):10.35±3.13 vs.5.23±2.11;NLR:8.84±6.07 vs.4.04±3.43;LYM(×109/L):1.45±0.52 vs.1.86±0.75;all P<0.05].The level of NLR in moderate-severe shock group was higher than that in mild shock group(12.16±7.49 vs.6.08±2.18,P<0.05).ROC curve showed that AUC,cut-off value,sensitivity,specificity and accuracy of NLR for predicting nosocomial CS after AMI were 0.848,6.055,74.54%,86.67%and 80.00%,respectively.Conclusion NLR has certain predictive value for nosocomial CS after AMI.
