Ethnicity, lipids and cardiovascular disease

Area of Science:

• Cardiovascular Medicine
• Genetics
• Epidemiology

Background:

• Cardiovascular disease (CVD) prevalence varies significantly across ethnic groups and geographic regions.
• Sub-Saharan African, Chinese, and Southeast Asian populations are projected to experience the largest increase in CVD mortality.
• Ethnic disparities in CVD prevalence are linked to differences in risk factors, including plasma cholesterol levels.

Purpose of the Study:

• To review recent evidence on ethnic variations in ischemic heart disease (IHD).
• To examine the correlation between IHD and genetic/acquired differences in plasma lipid and lipoprotein levels.
• To discuss ethnic differences in plasma lipid levels, apolipoprotein L1, and lipoprotein(a) [Lp(a)], and the impact of lipid-lowering therapy.

Main Methods:

• Literature review of recent evidence on ethnic differences in IHD and lipid profiles.
• Analysis of genetic and acquired factors influencing plasma lipid and lipoprotein levels.
• Discussion of current lipid-lowering therapies and implementation challenges.

Main Results:

• Ethnic variations exist in high-density lipoprotein-cholesterol (HDL-C), triglyceride levels, and Lp(a).
• These lipid differences may contribute to ethnic disparities in IHD risk.
• Residual cardiovascular risk may be higher in certain ethnic groups during lipid-lowering therapy.

Conclusions:

• Ethnic differences in HDL-C, triglycerides, and Lp(a) impact CVD risk and residual risk.
• Increased use of statins is recommended globally, with studies needed on diverse ethnic backgrounds.
• Further research is required to optimize lipid-lowering strategies for all ethnic groups.
