Brief summary

By the re-analysis, in the BIOTOOL-CHF DISCO study, of a previously enrolled cohort of patients, a Biological Congestion Score (BCS) was newly developed. The BCS integrates four congestion-related biomarkers with key clinical variables. The BIOTOOL-CHF VALID trial is designed to prospectively evaluate whether a BCS-assisted strategy for diuretic management improves clinical outcomes and quality of life in patients with chronic Heart Failure (HF) compared with standard care.

Detailed description

This prospective randomised study is part of a wider project that has been funded within the Horizon program by the call HORIZON-HLTH-2022-TOOL-11-01, project # 101095653, BIOTOOL-CHF. Herein the study will compare the outcomes of patients with chronic HF managed according to current usual clinical practice vs. patients in which therapy will be managed following the calculation of the BCS. In the BIOTOOL-CHF DISCO study, the BCS showed high accuracy in detecting congestion and better performance than clinical assessment in predicting outcomes, so it was hypothesized that, by providing a more accurate estimate of congestion in patients with chronic heart failure, the BCS may assist clinicians in managing diuretic therapy more accurately than the usual clinical assessment. The primary objective will be the comparison of standard-of-care management of chronic heart failure with a BCS-assisted strategy for guiding diuretic therapy, assessing the impact on a hierarchical composite clinical outcome at 3 months.

Interventions

OTHERIntervention: diuretic therapy guided by the Biological Congestion Score (BCS) using a predefined treatment nomogram

In patients randomized to the intervention arm, clinical variables and biomarker results will be entered into the score calculator. The calculator will provide to the clinician an estimate of the degree of congestion by the BCS, and the probability of cardiovascular hospitalization or death within the subsequent 3 months. Discrepancies will be recorded in the electronic Case Report Form (eCRF). Final decisions and eventual therapy adjustments will remain at the discretion of the caring physicians.

Win Ratio of Participants in Hierarchical Composite Endpoint (All-Cause Death, Heart Failure Events, and KCCQ-TSS Change) at 3 Months3 monthsTitle: Win Ratio of Hierarchical Composite Endpoint (All-Cause Death, Heart Failure Events, and Change in KCCQ-TSS) at 3 Months Description: To compare BCS-guided management vs. standard of care in chronic heart failure. The hierarchical composite endpoint is assessed using the win ratio method, combining in priority order: (1) time to all-cause death (days), (2) number of heart failure events (HF hospitalizations, emergency visits, or unplanned parenteral HF therapy; count), and (3) change from baseline in Kansas City Cardiomyopathy Questionnaire Total Symptom Score (KCCQ-TSS; range 0-100 points, higher scores indicate better health status). The three components are combined into a single win ratio value via the hierarchical win ratio method; no separate unit applies to each component independently. Unit of Measure: Win Ratio
