Plasma lipoprotein cholesterol in India in healthy persons and those with coronary heart disease
Insights
Indian subjects show higher HDL cholesterol, a key factor in preventing heart disease. This finding may explain the lower incidence of coronary heart disease (CHD) in India compared to Western nations.
Area of Science:
- Cardiovascular Science
- Lipid Metabolism
- Public Health
Background:
- Coronary heart disease (CHD) remains a significant global health concern.
- Understanding population-specific lipid profiles is crucial for assessing cardiovascular risk.
- Previous studies suggest variations in lipid levels across different ethnicities and geographical regions.
Purpose of the Study:
- To compare plasma lipid and lipoprotein cholesterol levels between healthy Indian subjects and patients with coronary heart disease (CHD).
- To investigate the influence of age and sex on lipid profiles in the Indian population.
- To explore the relationship between HDL cholesterol levels and CHD incidence in India.
Main Methods:
- Analysis of plasma total cholesterol and lipoprotein cholesterol levels.
- Data collected from 186 healthy Indian individuals and 213 Indian patients diagnosed with CHD.
- Statistical comparison of lipid profiles based on age, sex, and disease status.
Main Results:
- Plasma lipid and lipoprotein concentrations demonstrated variations with age.
- Men exhibited higher total cholesterol and LDL cholesterol compared to women.
- Women aged 20-49 years showed the highest HDL cholesterol levels.
- Significantly higher HDL cholesterol levels were observed in the Indian cohort compared to Western populations.
- HDL cholesterol levels were found to be negatively associated with CHD.
Conclusions:
- Elevated HDL cholesterol levels in the Indian population may contribute to a lower incidence of coronary heart disease (CHD).
- Age and sex are important determinants of lipid profiles in Indians.
- Further research is warranted to elucidate the protective mechanisms of high HDL cholesterol in preventing CHD within the Indian context.
Abstract:
The plasma total cholesterol and lipoprotein cholesterol levels are presented for 186 healthy Indian subjects and 213 patients with coronary heart disease (CHD). Plasma lipid and lipoprotein concentrations vary with age. Higher total cholesterol and LDL cholesterol were noted in men compared with women. HDL cholesterol is highest in women in the age group 20-49 years. HDL cholesterol levels (negatively associated with CHD) are significantly higher in India compared with western countries. It is suggested that the high level of HDL cholesterol may be responsible for the relatively low incidence of CHD in India.
