Time-to-Decongestion Following Heart Failure Hospitalization as Measured by Extracellular Fluid Nadir Using Bioimpedance Spectroscopy
The time required to achieve clinical decongestion is highly variable and often takes longer than may be anticipated; in our study it took an average of 16.9 days. Our results show that ECF is more sensitive than weight when tracking post-discharge decongestion. Noninvasive BIS measurements may assist clinicians with tracking fluid status in HF patients. ECF monitoring during the weeks following heart failure hospitalization may provide a more accurate measure of fluid status than weight alone.
