Rate-control or rhythm-control: where do we stand?

Area of Science:

• Cardiology
• Internal Medicine

Background:

• Atrial fibrillation is the most common sustained heart rhythm disturbance, with increasing global prevalence due to population aging.
• Current guidelines address acute symptomatic atrial fibrillation but lack consensus on the optimal long-term strategy for first or recurrent cases.
• Long-term management decisions impact quality of life, hospitalization risk, and severe complications like stroke and death.

Purpose of the Study:

• To review current knowledge on the long-term management of atrial fibrillation.
• To summarize evidence and identify areas requiring further clarification in atrial fibrillation treatment strategies.

Main Methods:

• This study is a literature review.
• It synthesizes existing evidence on two primary long-term management approaches for atrial fibrillation: rhythm control versus rate control.

Main Results:

• Rhythm control aims to restore sinus rhythm, potentially reducing the need for long-term antithrombotic therapy and associated bleeding risks (e.g., intracranial hemorrhage).
• Rate control, coupled with appropriate antithrombotic prophylaxis, may mitigate cardiovascular and non-cardiovascular side effects associated with antiarrhythmic drugs.
• The optimal long-term strategy remains debated, with ongoing considerations for quality of life and complication risks.

Conclusions:

• The best long-term approach for atrial fibrillation is not definitively established.
• Balancing the risks of bleeding from antithrombotics against the side effects of antiarrhythmic drugs is a key challenge.
• Further research is essential to clarify optimal management strategies for atrial fibrillation to improve patient outcomes.
