Objective To explore the evaluation value of serum levels of positive pentameric protein 3(PTX3)and creatine kinase isoenzyme MB(CK-MB)on volume load in patients with chronic decompensated heart failure(CDHF).Methods A total of 300 CDHF patients who visited the Xingtai Central Hospital from July 2019 to July 2022 were selected and divided into a capacity overload group(n=182)and a non capacity overload group(n=118)based on their capacity balance level.Two clinical data sets were compared and analyzed.The receiver operating characteristic(ROC)curve was used to analyze the evaluation value of serum PTX3 and CK-MB levels on the volume load of CDHF patients.The clinical disease characteristics of the two groups of patients were analyzed using univariate analysis,and the influencing factors of volume load of CDHF patients were analyzed using logistic regression.A column chart model was constructed and validated.Results The body mass index(BMI),waist circumference,systolic blood pressure,diastolic blood pressure,fasting blood glucose(FBG),glycosylated hemoglobin(HbA1c),C-reactive protein(CRP),uric acid(UA),homeostasis model assessment of insulin resistance(HOMA-IR)of patients in the capacity overload group were higher than those in the non-capacity overload group,and the differences were statistically significant(all P＜0.05).The PTX3,CK-MB,pulmonary capillary wedge pressure(PCWP),and CVP levels of patients in the capacity overload group were higher than those in the non-capacity overload group,while albumin,hemoglobin,and hematocrit were lower than those in the non-capacity overload group,and the differences were statistically significant(all P＜0.05).The ROC curve showed that the area under the curve(AUC)of PTX3 and CK-MB for predicting capacity overload in CDHF patients are 0.795 and 0.718,with sensitivity of 86.2％and 83.7％,specificity of 65.4％and 68.6％,respectively,indicating high predictive accuracy;The AUC of the two joint predictions is 0.817,the sensitivity was 92.5％,and the specificity was 70.6％.The prediction accuracy was higher than PTX3(Z=3.812,P＜0.05)and CK-MB(Z=3.365,P＜0.05).PTX3,CK-MB,albumin,hemoglobin,hematocrit,PCWP,and central venous pressure(CVP)were all influencing factors of volume load status in CDHF patients(all P＜0.05).The column chart risk prediction model established based on these factors had high accuracy and strong applicability in clinical treatment.Conclusions Serum PTX3 and CK-MB levels are influencing factors for volume overload in CDHF patients.A column chart model constructed in combination with indicators such as albumin,hemoglobin,hematocrit,PCWP,and CVP has high predictive value for the volume overload status of CDHF.
