Coronary heart disease risks in Asian Indians

Area of Science:

• Cardiology
• Public Health
• Genetics

Background:

• Asian Indian populations exhibit a disproportionately high prevalence of coronary heart disease (CHD).
• This includes both native populations and the significant diaspora residing in countries like the UK and US.
• Pathogenic factors contributing to CHD in this demographic have garnered substantial research interest.

Purpose of the Study:

• To investigate the underlying causes of accelerated atherosclerosis and CHD in Asian Indians.
• To highlight the role of genetic predisposition combined with lifestyle changes.
• To emphasize the need for early intervention and prevention strategies.

Main Methods:

• Review of documented risk factors including insulin resistance, central obesity, and dyslipidemia (high triglycerides, low HDL, high lipoprotein(a)).
• Analysis of the impact of lifestyle changes, termed 'westernization', on CHD prevalence.
• Comparison of CHD prevalence between urban and rural populations within India.

Main Results:

• Identified key metabolic risk factors: insulin resistance, central obesity, high triglycerides, low HDL, and high lipoprotein(a).
• Demonstrated that genetic predisposition is exacerbated by westernized lifestyles, leading to accelerated atherosclerosis.
• Observed increased CHD prevalence linked to lifestyle changes, with variations noted between urban and rural Indian settings.

Conclusions:

• Asian Indians possess a genetic predisposition to CHD, significantly worsened by westernized lifestyles.
• Early detection of risk factors and the implementation of preventive measures are essential.
• The findings underscore the importance of tailored public health strategies for this population.
