Abstract:
Objective To explore the prognostic value of plasma sST2 in the population of coronary heart disease(CHD)complicated with chronic kidney disease(CKD).Methods A total of 326 elderly patients with CHD or CKD undergoing physical examination in the Second Medical Center of Chinese PLA General Hospital from April 2021 to July 2022 were continuously enrolled,and according to whether having CHD or CKD,they were divided into a CHD-CKD comorbidity group(n=117),a CHD group(n=124),and a CKD group(n=85).Their baseline data were compared,and the plasma concentration of sST2 was detected using chemiluminescence assay.Multiple linear regression analysis was used to identify the relevant factors of sST2.Kaplan-Meier survival curve and Cox proportional hazards regression analyses were applied to determine the impact of plasma sST2 on all-cause mortality and major adverse cardiovascular events(MACE).Results There were significant differences among the three groups in terms of age,sST2 and NT-proBNP levels,Log(NT-proBNP),eGFR,ratios of hyperuricemia,cerebral infarction,tumors,and using anti-platelet drugs and statins,PR interval,LVEF,and TC,TG,HDL-C and Hb levels(P<0.05,P<0.01).Multiple linear regression analysis showed that the sST2 level was positively correlated with logNT-proBNP and negatively with Hb level in the comorbidity group(t=2.266,P=0.025;t=-2.235,P=0.021).Kaplan-Meier survival curve analysis indicated that during a median fol-low-up of 31.5(22.0,32.2)months,the comorbidity group had a lower survival rate than the two single-disease groups(P<0.05,P<0.01),and higher incidence of MACEs than the CKD group(P<0.01).ROC curve analysis suggests that the AUC value of sST2 in predicting all-cause mor-tality in the comorbid group was 0.692.Cox proportional hazards regression model revealed that after adjustment for cofounders,sST2 was still an independent risk factor for all-cause mortality in the comorbid patients(HR=4.461,95%CI:1.640-8.399,P=0.024),although this prognos-tic value may be influenced by NT-proBNP.Conclusion sST2 can independently predict the risk of mortality in elderly patients with CHD-CKD comorbidity.
