IVC collapse <30%, >5 pulmonary B lines, and NTproBNP >2000 pg/ml were associated with increased risk of HF death or admission, with NTproBNP having the best area under the curve.

Does assessment of volume status using IVC ultrasound, lung ultrasound, BIA, or NT-proBNP predict death or hospitalization in outpatients with chronic heart failure?
NT-proBNP, IVC ultrasound, and lung ultrasound are useful for evaluating congestion and identifying outpatients with chronic heart failure at high risk of hospitalization or death.
BACKGROUND: Heart failure (HF) is an important healthcare problem. Knowing volume status in outpatients with chronic HF to adjust treatment and to avoid decompensations is a challenge. The aim of this study is comparing the usefulness of inferior vena cava (IVC) ultrasound, lung ultrasound, bioelectrical impedance analysis (BIA), and natriuretic peptides in the follow-up of outpatients with chronic HF. METHODS: This was a prospective cohort study. Ninety-nine patients with chronic HF were included consecutively as they attended scheduled medical visits. The different techniques were performed on the day of the clinic visit, and the result was hidden from the patients and the responsible medical team. Follow-up time was 1 year. Outcome events checked were a combination of death or hospitalization, due to HF. RESULTS: Thirty-six patients (36.4%) died or were hospitalized for HF. They had a significantly lower IVC collapse, and a greater number of lung B-lines and higher NTproBNP levels compared to patients who remained stable. There were no differences in the BIA parameters. After multivariable analysis, cut-off points of IVC collapse <30%, number of pulmonary B lines greater than 5, and NTproBNP levels greater than 2000 pg/ml were associated with increased risk of HF death or admission. NTproBNP had the best area under the curve. CONCLUSION: Evaluation of congestion in outpatients with chronic HF may be based on NTproBNP, IVC ultrasound, or lung ultrasound; they are useful in identifying patients at high risk of hospitalization or death due to HF.
Curbelo et al. (Thu,) conducted a cohort in chronic heart failure (n=99). Inferior vena cava ultrasound, lung ultrasound, bioelectrical impedance analysis, and natriuretic peptides was evaluated on Combination of death or hospitalization due to HF. IVC collapse <30%, >5 pulmonary B lines, and NTproBNP >2000 pg/ml were associated with increased risk of HF death or admission, with NTproBNP having the best area under the curve.
