Arrhythmias and ion channelopathies causing sudden cardiac death in Hispanic/Latino and Indigenous populations

Area of Science:

• Cardiology
• Genetics
• Public Health

Background:

• Limited research exists on cardiac ion channelopathies and sudden cardiac death in Hispanic/Latino and Indigenous populations.
• These groups are often underrepresented in healthcare studies, leading to knowledge gaps.
• Existing literature points to healthcare disparities and unique risk factors within these demographics.

Purpose of the Study:

• To comprehensively review existing literature on cardiac ion channelopathies and sudden cardiac death in Hispanic/Latino and Indigenous populations.
• To examine genetic variants, epidemiology, etiologies, and clinical risk factors associated with arrhythmias in these underrepresented groups.
• To highlight the need for further research addressing health disparities and improving cardiovascular outcomes.

Main Methods:

• Systematic literature review of studies focusing on cardiac electrophysiology.
• Analysis of research concerning genetic variants, epidemiology, and risk factors for arrhythmias.
• Inclusion of studies addressing the Hispanic paradox and healthcare disparities in Indigenous populations.

Main Results:

• Identified a significant gap in research concerning cardiac ion channelopathies and sudden cardiac death in Hispanic/Latino and Indigenous populations.
• Highlighted the influence of socioeconomic factors (Hispanic paradox) and healthcare quality disparities on cardiovascular health in these groups.
• Confirmed the need for population-specific research to characterize genetic variants and risk factors.

Conclusions:

• There is a critical need for expanded research on cardiac ion channelopathies and sudden cardiac death in Hispanic/Latino and Indigenous populations.
• Further studies are essential to characterize pathogenic genetic variants and identify population-specific risk factors.
• Addressing health disparities is crucial for improving the detection, prevention, and management of arrhythmias and sudden cardiac death in these demographics.
