What this trial is about
Systemic venous congestion is the primary therapeutic target of intravenous loop diuretics in patients admitted for acute heart failure (AHF). Despite their utility, a significant proportion of AHF patients are discharged with persistent clinical symptoms of congestion (residual congestion). Therefore, in recent years, there has been a growing focus on the use of tools (biomarkers, clinical ultrasound) that allow us to optimize diuretic treatment and thereby improve the prognosis of AHF patients. The objective is to analyze whether the strategy of guiding intravenous loop diuretic dosing based on intra-abdominal pressure(IAP) measurements and clinical ultrasound is superior to the conventional strategy employed in daily clinical practice. This study is a randomized, multicenter clinical trial involving consecutive patients admitted with a diagnosis of AHF in the Internal Medicine and Cardiology departments. Patients who meet the inclusion criteria, after signing informed consent, will be randomized into two groups: 1) Diuretic treatment guided by usual clinical practice and 2) Treatment guided by intra-abdominal pressure levels and clinical ultrasound (inferior vena cava and portal Doppler). This strategy will be maintained during the first 72 hours of admission, with a thorough analysis of congestion and diuretic response being conducted.
