Conclusion
The exploration of cardiac ion channelopathies and SCD across diverse populations has illuminated significant disparities in healthcare access, treatment effectiveness, and genetic understanding. Studies focusing on AA and Asian populations have revealed underrepresentation in clinical trials and socioeconomic factors contributing to increased SCD risk. Similarly, the dearth of research in Hispanic/Latino and Indigenous populations underscores the urgent need for comprehensive studies to address genetic risk factors and socioeconomic disparities affecting SCD susceptibility. Despite the challenges, recent investigations have shed light on the prevalence and risk factors of arrhythmias in Hispanic/Latino and Indigenous communities, offering valuable insights into potential cardioprotective factors and genetic variants associated with these conditions. Moving forward, collaborative efforts involving international and inter-institutional studies are essential to establish consensus on genetic influences and develop targeted interventions tailored to various ethnic subgroups. By prioritizing research in these underserved populations, significant progress towards bridging healthcare disparities and improving outcomes for individuals affected by cardiac ion channelopathies across diverse ethnicities can be achieved.
