EP: 8.Role of Diuretics in Heart Failure Management

Diuretics serve as essential but symptomatic therapy in heart failure management, functioning primarily as a “bailout strategy” for volume management rather than as disease-modifying treatment. While necessary for managing congestion in many patients, escalating diuretic requirements often signal the need to optimize other guideline-directed medical therapies that provide more comprehensive disease modification. The relationship between effective guideline-directed medical therapy and reduced diuretic needs has become increasingly apparent, with therapies like SGLT2 inhibitors and glucagon-like peptide-1 receptor agonists demonstrating decongestive properties that can reduce diuretic requirements.

Clinical management of diuretics has become more sophisticated, incorporating urinalysis to assess diuretic effectiveness beyond simple volume assessment. Understanding urinary composition and response patterns can guide more nuanced diuretic strategies and help identify patients who might benefit from alternative approaches. Loop diuretics remain the cornerstone, often augmented by thiazides to enhance effectiveness, though clinicians must remain vigilant about hyperkalemia risks with combination therapy.

Innovation in diuretic delivery includes emerging formulations such as subcutaneous and intranasal preparations, though their precise role in clinical practice remains to be defined. While these novel formulations may offer improved tolerability or effectiveness for select patients, their integration into standard care requires careful consideration. The potential for high-dose chronic diuretic therapy to cause deleterious effects including renal dysfunction and neurohormonal activation underscores the importance of optimizing other heart failure therapies to minimize diuretic dependence while maintaining effective volume management.
