Abstract:
Objective To explore the guiding value of bioimpedance vector analysis (BIVA) in the hy-dration of the patients undergoing coronary angiography (CAG) in order to provide the practical and strongly operable objective indicators for clinical practice reducing the occurrence of contrast agent-related acute renal injury (CI-AKI).Methods The convenience sampling method was used to select 72 inpatients with coronary heart disease who underwent CAG for the first time in the department of cardiovascular medicine in this hos-pital from August to October 2023.The basic information of the patients was collected,the blood biochemistry and N-terminal pro-brain natriuretic peptide (NT-ProBNP) were collected,and the preoperative body moisture situation was obtained by BIVA.The laboratory data and contrast agent dosage were extracted from LIS sys-tem and nursing document system.The SPSS27.0 software was used to analyze the correlation between pre-operative body water and postoperative creatinine level,glomerular filtration rate (eGFR),CI-AKI.The rec-ommended range of total body water in this study was calculated by the formula (90% probability).Results The total body moisture measured before operation in the patients with CAG had weakly positive correlation with eGFR on postoperative 1 d (r=0.19,P=0.02).The total body moisture had weakly negative correlation with creatinine on postoperative 1 d (r=-0.23,P<0.01),slightly negative correlation with cre-atinine on postoperative 3 d (r=-0.24,P=0.04),and moderately negative correlation with postoperative CI-AKI occurrence (r=-0.35,P<0.01);the proportion of body water had slightly positive correlation with eGFR on postoperative 3 d (r=0.22,P=0.01).With the no occurrence of CI-AKI in the patients with CAG as the target,according to the formula calculation,it is suggested that the total body moisture range (90% probability) of this study should not be less than 33.25 L.Conclusion BIVA is of guiding significance for the hydration of the patients with CAG.
