Racial and Ethnic Disparities in Stroke Prevention for Atrial Fibrillation

Area of Science:

• Cardiology
• Public Health
• Pharmacogenomics

Background:

• Racial and ethnic disparities in healthcare are significant but often overlooked.
• Underrepresented ethnic groups with atrial fibrillation may face higher stroke risks and severity.
• Anticoagulant therapy is complex due to non-uniform bleeding risks and pharmacogenetic influences.

Purpose of the Study:

• To review the challenges in stroke prevention for underrepresented ethnic groups with atrial fibrillation.
• To highlight the interplay of stroke risk, bleeding complications, and pharmacogenetics in these populations.
• To inform clinical practice and research regarding equitable stroke prevention strategies.

Main Methods:

• This study is a narrative review.
• Literature search on racial/ethnic disparities in atrial fibrillation, stroke, bleeding, and anticoagulation.
• Synthesis of existing evidence on pharmacogenetics and treatment outcomes.

Main Results:

• Evidence suggests increased stroke risk and severity in certain ethnic minority populations with atrial fibrillation.
• Pharmacogenetic variations can influence anticoagulant efficacy and bleeding risk.
• Current guidelines may not fully address the specific needs of diverse patient groups.

Conclusions:

• Addressing disparities in stroke prevention for atrial fibrillation requires a nuanced approach.
• Personalized anticoagulant therapy considering pharmacogenetics is crucial for underrepresented ethnic groups.
• Further research is needed to optimize stroke prevention and reduce health inequities in diverse atrial fibrillation patients.
