Abstract: South Asians (SAs), people from the Indian subcontinent (e.g., India, Pakistan,
Bangladesh, Sri Lanka, and Nepal) have a higher prevalence of cardiovascular disease (CVD) and
suffer from a greater risk of CVD-associated mortality compared to other global populations. These
problems are compounded by the alterations in lifestyles due to urbanization and changing cultural,
social, economic, and political environments. Current methods of CV risk prediction are
based on white populations that under-estimate the CVD risk in SAs. Prospective studies are required
to obtain actual CVD morbidity/mortality rates so that comparisons between predicted CVD
risk can be made with actual events. Overwhelming data support a strong influence of genetic factors.
Genome-Wide Association Studies (GWAS) serve as a starting point for future genetic and
functional studies since the mechanisms of action by which these associated loci influence CVD is
still unclear. It is difficult to predict the potential implication of these findings in clinical settings.
This review provides a systematic assessment of the risk factors, genetics, and environmental causes
of CV health disparity in SAs, and highlights progress made in clinical and genomics discoveries
in the rapidly evolving field, which has the potential to show clinical relevance in the near future.
