A Personalized Approach to the Management of Congestion in Acute Heart Failure

Area of Science:

• Cardiology
• Nephrology
• Pharmacology

Background:

• Heart failure (HF) involves neurohumoral pathway hyperactivation.
• Cardiorenal interactions are critical in HF progression.
• Diuretics are essential for managing hypervolemia in acute decompensated heart failure (ADHF).

Purpose of the Study:

• To clarify the complex management of congestion in ADHF.
• To emphasize the importance of understanding cardiorenal interactions in ADHF.
• To guide the effective use of diuretics and post-discharge care.

Main Methods:

• Review of cardiorenal interactions in ADHF.
• Analysis of diuretic use and impact on renal function.
• Assessment of volemia and guideline-directed medical therapy (GDMT).

Main Results:

• Congestion can impair renal function and requires aggressive treatment.
• Transient serum creatinine elevations during decongestion do not predict worse outcomes.
• Maintaining diuretics in hypervolemic patients is recommended.
• Urinary sodium monitoring can personalize diuretic therapy.
• Adequate volemia assessment and GDMT titration are vital before discharge.

Conclusions:

• Aggressive decongestion is necessary in ADHF, even with temporary creatinine increases.
• Personalized diuretic management, including urinary sodium monitoring, improves response.
• Comprehensive pre-discharge assessment and early post-discharge follow-up are crucial to prevent readmissions.
