Coronary artery disease: an overview of risk factors
1Department of Laboratory Medicine and Pathology, University of Minnesota Medical School, Minneapolis 55455.
Insights
Coronary artery disease (CAD) poses a global health challenge, with South Asians exhibiting a higher risk due to specific metabolic factors. Understanding these unique risk factors is crucial for targeted prevention and management strategies.
Area of Science:
- Cardiovascular Medicine
- Public Health
- Epidemiology
Background:
- Coronary artery disease (CAD) is a leading cause of death globally, affecting both industrialized and developing nations.
- Identified risk factors for CAD include cholesterol, smoking, hypertension, obesity, diabetes, stress, and physical inactivity.
- South Asian populations demonstrate a disproportionately higher risk for coronary heart disease.
Purpose of the Study:
- To review existing data on CAD and its pathogenesis.
- To emphasize the specific risk factors and challenges unique to South Asian populations.
Main Methods:
- Literature review of available data on CAD.
- Analysis of epidemiological studies focusing on South Asian immigrants.
Main Results:
- South Asians exhibit a higher prevalence of CAD risk factors compared to other ethnic groups.
- Specific risk factors in South Asians include higher rates of diabetes, hypertension, insulin resistance, dyslipidemia (low HDL, high LDL, high triglycerides), and obesity.
- These factors contribute significantly to the increased burden of CAD in this population.
Conclusions:
- CAD is a significant health concern with unique risk profiles in South Asian populations.
- Addressing the specific risk factors prevalent in South Asians is essential for effective CAD prevention and management.
- Further research into the unique pathogenesis of CAD in South Asians is warranted.
Abstract:
Coronary artery disease (CAD) is an important cause of morbidity and mortality in most industrialized nations, and is gaining in importance as a major disease in developing countries as well. Several risk factors, such as cholesterol, smoking, hypertension, obesity, diabetes, stress and physical activity, have been identified as contributors to the pathogenesis of this disease. Studies done in many countries on South Asian immigrants clearly demonstrate the increased risk for coronary heart disease in this population compared to that of local ethnic groups. Higher prevalence of diabetes, blood pressure, glucose intolerance, insulin resistance, low levels of HDL-cholesterol, high levels of LDL-cholesterol, increased plasma triglycerides and obesity are some of the risk factors identified as contributing to CAD in South Asians. The present report will review briefly the available data on CAD and its pathogenesis with particular emphasis on the problems unique to South Asians.
