About this trial

The K-PROSE study is a randomized clinical investigation evaluating strategies to prevent contrast-induced acute kidney injury (CI-AKI) in patients hospitalized with acute heart failure and moderate renal dysfunction (eGFR 30-75 mL/min/1.73 m²). Patients requiring contrast-enhanced CT imaging are randomized to either standard intravenous saline hydration or a furosemide-based decongestion strategy. Renal function is assessed using serial measurements of creatinine and cystatin C, before and after contrast exposure. By comparing renal outcomes, congestion status, and safety profiles, this study aims to determine whether a decongestion-focused approach provides superior renal protection compared with conventional hydration in high-risk acute heart failure patients.

Disqualifiers

Requirement for vasopressor therapy

Requirement for renal replacement therapy (dialysis)

Known allergy or hypersensitivity to furosemide

Ongoing acute coronary syndrome
