Diuretic Use in Heart Failure

Area of Science:

• Cardiology
• Nephrology
• Pharmacology

Background:

• Heart failure (HF) is a leading cause of morbidity and mortality globally.
• HF involves neurohumoral activation and salt/water retention, worsening congestion.
• Diuretics are essential for managing HF by inducing natriuresis and alleviating symptoms.

Purpose of the Study:

• To review diuretic classes, mechanisms of action, and clinical applications in HF management.
• To discuss strategies for optimizing diuretic therapy in outpatient and inpatient settings.
• To address challenges in HF management, including chronic kidney disease and diuretic resistance.

Main Methods:

• Review of current literature on diuretics in heart failure.
• Discussion of pathophysiological mechanisms of HF and fluid retention.
• Analysis of clinical practice guidelines and evidence for diuretic use.

Main Results:

• Diuretics effectively reduce volume overload and improve HF symptoms.
• Different diuretic classes have varying potencies and sites of action.
• Optimal use requires monitoring electrolytes, renal function, and patient weight.

Conclusions:

• Diuretics are indispensable in HF management across all stages.
• Tailored diuretic strategies are necessary, especially in patients with CKD.
• Emerging technologies like remote monitoring may enhance HF care.
