Clinical Application of Phase Angle and BIVA Z-Score Analyses in Patients Admitted to an Emergency Department with Acute Heart Failure

The scope of this research is to demonstrate the clinical applicability of the phase angle by bioelectrical impedance analysis and C-corp analysis within the emergency department, and how phase angle can be a predictive marker for death or readmission at 90 days after discharge. Recent research has been focused on studying the role of face angle congestion and reduced body cell mass by biological appearance, bacteria analysis as predictors of poor prognosis in patients with acute heart failure. We have found that the detection of subclinical congestion by bioelectrical impedance bacteria analysis has been predicting outcomes such as mortality, readmissions, and unplanned emergency department visits.

Having a quick, accurate and reliable method to assess congestion status and estimate body cell mass at the bedside can aid physicians in making medical decisions to improve a patient’s prognosis. Bioelectrical impedance spectral analysis C score can be used to assess congestion and detect changes in nutritional and nutritional status in patients with acute and current heart failure during hospitalization. It can compliment other diagnostic tests and serve as a monitoring tool.

Begin by removing the shoe and sock from the patient’s right foot. Also remove all metal objects in contact with the patient’s skin, such as bracelets, watches, rings, and chains. Position the patient’s supine or semi fowler position with their legs and arms spread at approximately 45 degrees.

To measure BIA, clean the surfaces using a 70%alcohol pad and allow them to dry completely before placing the electrodes. Download the BIVA tolerance software by Piccoli. Open the reference population sheet.

Copy the appropriate reference population based on the patient’s characteristics and paste it in the first yellow row. Click on the Z-score sheet. Insert the reference population and enter the medical record number of each patient into the subject ID field.

Next, input a number between one and 10 in the group code field. Insert the resistance value obtained with BIA and adjust it by height and meters into the resistance divided by height, subject field, and the reactance value into the reactance divided by height subject field. Then input one in the drawing option field to generate a plot.

Navigate to the spreadsheet program menu. Select the add-ins tab and click the calculate button. Click on the Z graph sheet within the spreadsheet program.

Navigate to the add-ins tab. Click the new graph button. Then proceed with conducting BIVA Z-score and phase angle analyses.
