VExUS in Patients With Acute Heart Failure

Congestion Assessment Using Venous Excess Ultrasound Score (VExUS) in Patients With Acute Heart Failure

The importance of assessing venous congestion in heart failure patients is widely acknowledged, but its study is hampered by the lack of a practical evaluation tool. Venous excess ultrasound score (VExUS) is a promising noninvasive ultrasound-guided modality that can detect and objectify clinically significant organ congestion. VExUS congestion grading score was still not formally validated in patients with AHF, as there is limited data on its clinical application in this group of patients.

Study Overview

Detailed Description

It is currently unknown whether changes in systemic venous congestion, assessed by venous excess ultrasound score (VExUS), are associated with worsening renal function, reduced diuretic and natriuretic response, and poor prognosis in patients with acute decompensation of heart failure (AHF).

This prospective, observational, single-center study included patients admitted to the intensive care unit with AHF. At admission all patients undergo bedside Doppler ultrasound of inferior vena cava, hepatic, portal and renal veins to determine blood flow patterns. Congestion was graded with the VExUS score (grade 0, grade 1, grade 2, grade 3). Sodium concentration in a spot urine sample was assessed in 1 hour after first standard intravenous loop diuretic administration. The primary endpoint was the development of acute kidney injury (AKI), defined as oligoanuria (diuresis rate <0.5 ml/kg/hour for 6 hours) and an increase of serum creatinine >26 µmol/l within a 48-hour period or 50% from baseline creatinine within a week. The secondary endpoints were in-hospital mortality, change in spot urine sodium content <50 mmol/l and development of diuretics resistance (defined as the need to double starting dose of intravenous furosemide in 6 hours without adding a different class of diuretic agents).

Study Population

The study involved patients over 18 years of age admitted to the hospital with AHF and requiring intravenous administration of loop diuretics. Diagnosis was based on the European Society of Cardiology (ESC) HF guidelines, with patients presenting with dyspnoea at rest or with minimal exertion and signs and symptoms of congestion (rales on chest auscultation, peripheral oedema, swelling of the cervical veins, hepatomegaly, ascites, hepatojugular reflux) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) >1000 pg/ml.

Intervention / Treatment
Patients with acute decompensated heart failure
The study involved patients over 18 years of age admitted to the hospital with acute heart failure and requiring intravenous administration of loop diuretics. Diagnosis was based on the European Society of Cardiology (ESC) heart failure guidelines, with patients presenting with dyspnoea at rest or with minimal exertion and signs and symptoms of congestion (rales on chest auscultation, peripheral oedema, swelling of the cervical veins, hepatomegaly, ascites, hepatojugular reflux) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) >1000 pg/ml.
All patients upon admission undergo ultrasound assessment of diameter and collapsibility of the inferior vena cava, hepatic vein Doppler, portal vein Doppler, intra-renal venous Doppler.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Development of acute kidney injury (AKI)
Time Frame: During 7 days of hospital stay
Assessment of patient's serum creatinine at admission, in 48 hours, at day 7, and calculation of the amount of urine output in the first 6 h after the administration of a loop diuretic.
During 7 days of hospital stay

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
In-hospital mortality
Time Frame: During patient's hospital stay (up to 14 days)
Death from any cause, whichever came first
During patient's hospital stay (up to 14 days)
Development of diuretics resistance (defined as the need to double initial dose of intravenous furosemide in 6 hours without adding a different class of diuretic agents)
Time Frame: 6 hours after first intravenous furosemide administration
Assessment of diuretic response: patient's urine output (ml/kg/hour) in the first 6 hours and patient's medical record with doses of administered diuretics.
6 hours after first intravenous furosemide administration
Change in spot urine sodium content <50 mmol/l
Time Frame: 1 hour after first standard intravenous loop diuretic administration after patient's admission.
Sodium concentration in a spot urine sample is assessed in 1 hour after first intravenous loop diuretic administration. Reduction of natriuretic response in the face of congestion with volume overload with spot urine sodium content <50 mEq/L generally identifies a patient with an insufficient diuretic response.
1 hour after first standard intravenous loop diuretic administration after patient's admission.
