Contemporary indications and therapeutic implications for digoxin use.

Area of Science:

• Cardiology
• Pharmacology

Background:

• Heart failure (HF) significantly contributes to morbidity and mortality.
• Standard HF therapies include ACE inhibitors and beta-blockers, but digoxin's role is debated.
• Digoxin is recommended for symptomatic HF and atrial fibrillation rate control.

Purpose of the Study:

• To conduct a systematic literature review on current indications for digoxin.
• To highlight clinical settings where digoxin is indicated, despite its underuse.
• To emphasize digoxin's continued relevance in acute and chronic cardiac conditions.

Main Methods:

• Systematic literature search for current digoxin indications.
• Review of existing research and safety data on digoxin.
• Analysis of clinical settings where digoxin is recommended.

Main Results:

• Digoxin is prescribed 20 million times annually in the US.
• The drug exhibits favorable hemodynamic effects in HF and atrial tachyarrhythmias.
• Despite evidence, digoxin is suggested to be underused in clinical practice.

Conclusions:

• Digoxin is indicated for symptomatic HF patients and atrial fibrillation rate control.
• Challenges exist in prospective studies for acute HF, yet digoxin's role persists.
• Digoxin is crucial for optimizing care in specific acute and chronic cardiac conditions.
