BACKGROUND: Predicting fluid volume that needs to be removed in @entity712 ( @entity712 ) @entity1 remains challenging. Thoracic admittance (TA), the reciprocal of thoracic impedance measured by bioelectrical impedance, reflects the amount of fluid in the thorax. Abdominal organs play an important role in @entity712 as systemic fluid reservoirs. We investigated the relationship between @entity1661 ( @entity1661 ) at the time of admission for @entity712 and net @entity393 (NFL) during hospitalization. METHODS: Sixty-two consecutive @entity1 hospitalized for @entity712 [age 71  10 years, @entity1002 ( @entity1002 ) 39  17%] were studied. The admittance values, i.e. the reciprocals of the impedance values, were derived using a BioZ(  ) (CardioDynamics, San Diego, CA, USA). The change in weight from admission to discharge was used as a surrogate of amount of NFL. RESULTS: At the time of admission, a significant correlation was detected between TA and @entity1661 (r=0.46, p=0.0001). TA at admission was significantly correlated with the LV structural variables (end-diastolic dimension and end-systolic dimension), and serum @entity1372 level. @entity1661 at admission was significantly correlated with New York Heart Association (NYHA) class and plasma BNP, and also correlated with @entity1002 and variables related to systemic congestion [minimal inferior vena cava (IVC) diameter and tricuspid regurgitation grade]. Neither TA nor @entity1661 values were significantly correlated with weight at admission. During hospitalization, TA and @entity1661 declined from 44  8k  (-1) to 36  6k  (-1) (p<0.0001) and from 74  25k  (-1) to 56  17k  (-1) (p<0.0001), respectively. Weight fell from 60.1  10.8kg to 54.5  9.4kg (p<0.0001), while NFL was 5.8kg (range, 0.1-17.5kg). In univariate analyses, the admission NYHA class, TA, @entity1661 , weight, and IVC diameter correlated with NFL. Multivariate analysis demonstrated that only admission weight [standardized partial regression coefficient (SPRC)=0.596], @entity1661 (SPRC=0.529), and NYHA class (SPRC=0.277) were independent predictors of NFL. CONCLUSION: Abdominal admittance measurement helps to predict the amount of fluid volume to be removed in @entity1 with @entity712 .

Abdominal admittance helps to predict the amount of fluid accumulation in XXXX with @entity712 .
