Brief Summary

Acutely decompensated heart failure (ADHF) is highly prevalent and has a high (financial) burden on the health care system. Treatment often consists of the administration of IV decongestive agents. Adequate dosing is difficult due to varying diuretic resistance and inadequate parameters to evaluate the response. Urine sodium is a promising biomarker to evaluate the diuretic response. It is hypothesized that a tailored, urine sodium guided diuretic algorithm will result in faster and more complete decongestion and therefore lead to better survival (in terms of mortality and heart failure events) while being non-inferior in terms of safety (mainly regression of kidney function).

Detailed Description

Rationale: Acutely decompensated heart failure is a highly prevalent diagnosis with a high burden on resources and a high risk of mortality and re-hospitalization. The prescription of diuretics to relieve congestion has been the cornerstone of treatment for years, but evidence about diuretic response and adequate dosing is still lacking. Inadequate diuretic response (and insufficient decongestion) has a negative influence on outcome but is often not timely addressed. Urinary sodium (Ur-Na) is a promising biomarker in the prediction of diuretic response to the prescribed dose. It is hypothesized that an Ur-Na based, intensified algorithm can help tailor diuretics in an individual way, but sufficient evidence to support its implementation is lacking.

Objective: Investigate if a tailored diuretic algorithm based on Ur-Na has a positive effect on a primary endpoint of reduction in a combined endpoint of death, heart failure events and change in the Kansas City questionnaire total symptom score (KCCQ-TSS) versus standard clinical care in patients hospitalized with AHF, without imposing safety concerns (e.g. worsening renal function).

Study design: Prospective, Single-Blinded, Randomized, Blinded-endpoint trial

Study population: Patients admitted with acutely decompensated heart failure (diagnosed according to the 2021 ESC (European Society of Cardiology) guidelines) who are 18 year or older.

Intervention: Arm I: Tailored, Ur-Na based, intensified diuretic strategy; Arm II: Usual care

Main study parameters/endpoints: Hierarchical composite endpoint of all-cause death, heart failure events and a 4-point or greater difference in Kansas City questionnaire total symptom score (KCCQ-TSS); assessed using a win-ratio approach.

Primary Outcome Measures
NameTimeMethod
Hierarchical composite of all-cause mortality, heart failure events and delta quality of life at 90 days follow-up.90 days after inclusion

The primary endpoint is a hierarchical composite calculated using a win-ratio approach of:

i) Mortality (all-cause) at 90 days after hospitalization; ii) Heart failure events at 90 days after hospitalization (1. a \>2 times increase in oral loop diuretic dose, 2. the need for iv administration of loop diuretics, 3. an emergency department visit or hospitalization for HF), wherein a single event or hospitalization will be sufficient to reach the combined endpoint; iii) Delta in quality of life measured using the Kansas City Cardiomyopathy Questionnaire total symptom score (KCCQ-TSS) from baseline to 90 days after hospitalization
