Abstract: Objective To analyze the prediction value of serum levels of soluble tumor necrosis factor like weak inducer of apoptosis(sTWEAK) and tissue kallikrein 1(KLK1) for the prognosis of the elderly patients with acute non-ST segment elevation myocardial infarction(NSTEMI) after emergency percutaneous coronary intervention(PCI). Methods The data of 117 elderly patients with NSTEMI receiving emergency PCI in our hospital from April 2018 to December 2019 were retrospectively analyzed. The serum levels of sTWEAK, KLK1, cardiac troponin T(cTnT)and creatine kinase MB(CK-MB) at admission and 1 d after PCI were observed and compared. Aceording to the prognosis 1 year after PCI, the patients were divided into the good prognosis group and the poor prognosis group, and the serum levels of sTWEAK and KLK1 were compared between the two groups.The prediction value of serum sTWEAK and KLK1 was analyzed. Results The levels of sTWEAK, cTnT and CK-MB were significantly lower and the level of KLK1 was higher in 117 elderly patients with NSTEMI 1 day after PCI than those at admission(P<0.05). After 1 year of follow-up, there was 32 cases (27.35%)showing poor prognosis, and the level of sTWEAK in the poor prognosis group was higher and the level of KLK1 was lower than that in the good prognosis group(P<0.05).Logistic regression analysis showed that the over expression of sTWEAK (OR=1.167,95%CI: 1.095-1.243)and low expression of KLK1(OR=0.526, 95%CI: 0.402-0.688) might be risk factors for poor prognosis of emergency PCI in the elderly NSTEMI patients(P<0.05). Receiver operating characteristic curve(ROC) curve was drawn and showed that the AUC of serum sTWEAK and KLK1 or combination in predicting the prognosis of emergency PCI in the elderly NSTEMI patients was 0.814, 0.895 and 0.907 respectively. Conclusions The poor prognosis may be related to the over expression of sTWEAK and the low expression of KLK1. Early detection of sTWEAK and KLK1 levels at admission has certain predictive value for the prognosis in the elderly NSTEMI patients after the emergency PCI.
