Abstract
Heart failure is a clinical syndrome, resulting in increased intracardiac pressure and/or decreased cardiac output under rest or stress. In acute decompensated heart failure, volume assessment is essential for clinical diagnosis and management. More and more evidence shows the advantages of bioimpedance vector analysis in this issue. Here, we critically present a brief review of bioimpedance vector analysis in the prediction and management of heart failure to give a reference to clinical physicians and guideline makers.
Highlights
Heart failure (HF) is a clinical syndrome characterized by signs and symptoms associated with abnormal cardiac function and/or structure, resulting in increased intracardiac pressure and/or decreased cardiac output under rest or stress [1, 2]
bioimpedance vector analysis (BIVA) was more accurate than brain natriuretic peptide (BNP) in detecting peripheral congestion in acute HF (AHF) (the area under the curve (AUC) was 0.88 vs. 0.57 respectively; P < 0.001) [25]
BIVA was more accurate than BNP in detecting peripheral congestion in chronic HF (CHF) (AUC was 0.89 vs. 0.68, respectively; P < 0.001) [25]
Summary
Heart failure (HF) is a clinical syndrome characterized by signs and symptoms associated with abnormal cardiac function and/or structure, resulting in increased intracardiac pressure and/or decreased cardiac output under rest or stress [1, 2]. There are many kinds of electrical circuits to describe the behavior of biologics, the most common and simplest are series connection and parallel connection (Figure 1C) Both resistance and capacitive reactance can be measured at the same frequency [mostly 50 kHz [24], Figure 1D]. The hydration state measured by BIVA in the AHF group was significantly decreased 72 h after diuretic medication treatment and at discharge [28]. Routine laboratory testing, such as brain natriuretic peptide (BNP)/N-terminal pro BNP (NT-pro BNP) [2, 40], is of great clinical significance for the reaction of peripheral fluid accumulation. No changes in CIEDs were found at 0.5 and 1 year of follow-up [31], suggesting that BIVA performance
