Current Controversies and Challenges in Brugada Syndrome

Area of Science:

• Cardiology
• Genetics
• Electrophysiology

Background:

• Brugada syndrome, first described in 1993, is an inherited cardiac arrhythmia associated with an increased risk of sudden cardiac death.
• Despite extensive research, significant controversies persist regarding its diagnosis, risk assessment, and management.

Purpose of the Study:

• To provide a comprehensive overview of the current challenges in Brugada syndrome.
• To critically evaluate diagnostic criteria, risk stratification methods, and therapeutic interventions.
• To summarize the latest insights into the pathophysiology of Brugada syndrome.

Main Methods:

• This review synthesizes existing literature on Brugada syndrome.
• It analyzes current diagnostic guidelines and risk stratification scores.
• It examines pharmacological and interventional treatment options and pathophysiological mechanisms.

Main Results:

• Diagnostic criteria for Brugada syndrome remain debated, impacting accurate identification.
• Risk stratification of asymptomatic patients is challenging, with limited consensus on optimal strategies.
• Current management focuses on risk reduction through lifestyle modifications, medications, and device implantation, though evidence is evolving.
• Pathophysiological understanding continues to advance, implicating genetic and molecular factors.

Conclusions:

• Brugada syndrome diagnosis and management require a multidisciplinary approach.
• Further research is needed to refine diagnostic criteria and risk stratification tools.
• Personalized therapeutic strategies are essential for improving outcomes in Brugada syndrome patients.
