Atrial fibrillation in patients with systolic heart failure: pathophysiology mechanisms and management

Area of Science:

• Cardiology
• Internal Medicine

Background:

• Heart failure (HF) and atrial fibrillation (AF) prevalence is rising globally, particularly in aging populations.
• HF and AF share common risk factors and pathophysiological pathways, leading to a complex interrelationship.
• AF can worsen HF by impairing cardiac function, while HF structural changes increase AF risk.

Purpose of the Study:

• To explore the intricate relationship between heart failure and atrial fibrillation.
• To discuss the impact of the temporal relationship between HF and AF on clinical management.
• To highlight current and future therapeutic strategies for managing concomitant HF and AF.

Main Methods:

• Review of existing literature on the pathophysiology and clinical management of HF and AF.
• Analysis of how the interplay between these conditions influences diagnostic and therapeutic approaches.
• Consideration of advancements in genetic profiling for improved understanding.

Main Results:

• The co-existence of HF and AF necessitates tailored treatment plans focusing on rate/rhythm control and thromboembolism prophylaxis.
• The temporal sequence of HF and AF development impacts prognosis and management strategies.
• Emerging research in pathophysiological interdependence and genetic profiling offers new diagnostic and preventive avenues.

Conclusions:

• Effective management of co-existing HF and AF requires addressing both conditions comprehensively.
• Further research into their pathophysiological links and genetic underpinnings is vital for advancing patient care.
• Personalized treatment strategies hold promise for improving outcomes in patients with HF and AF.
