Coronary Atherosclerosis
Coronary atherosclerosis, a leading cause of cardiovascular disease, is a complex condition influenced by multiple risk factors. While its exact cause remains incompletely understood, extensive research has identified key contributors to its development and progression.

Key Points
- Coronary atherosclerosis is influenced by a combination of modifiable and non-modifiable risk factors.
- Early atherosclerotic lesions can begin in childhood, highlighting the importance of prevention.
- Lifestyle changes and risk factor management are critical for reducing disease incidence.
Risk Factors
Non-Modifiable Risk Factors
- Age and gender:
- More common in individuals over 40 years old, with rapid progression after age 49.
- Lower incidence in women compared to men, but increases after menopause.
- Heredity:
- Family history of coronary atherosclerosis increases susceptibility.
Modifiable Risk Factors
- Occupation:
- Sedentary jobs, intense mental activity, and chronic stress increase risk.
- Diet:
- High consumption of animal fats, cholesterol, sugar, and salt is associated with higher risk.
- Blood lipids:
- Hyperlipidemia significantly contributes to disease development.
- Blood pressure:
- Hypertension increases prevalence by four times compared to normal blood pressure.
- Smoking:
- Smoking elevates both incidence and mortality rates.
- Obesity:
- Obese individuals are at higher risk, even if their weight is within a normal range.
- Diabetes:
- Diabetes patients have a higher incidence rate than non-diabetic individuals.
Emerging Risk Factors
- Dietary antioxidants:
- Lack of antioxidants in the diet may contribute to disease progression.
- Iron storage:
- Increased iron levels in the body are associated with higher risk.
- Insulin resistance:
- A key factor in metabolic syndrome and atherosclerosis.
- Genetic factors:
- Overexpression of the angiotensin-converting enzyme (ACE) gene.
- Coagulation factors:
- Elevated levels of certain coagulation factors in the blood.
- Homocysteine levels:
- High homocysteine levels are linked to vascular damage and atherosclerosis.
Implications for Prevention
- Lifestyle modifications:
- Adopting a heart-healthy diet, regular physical activity, and stress management.
- Medical management:
- Controlling blood pressure, cholesterol, and blood sugar levels.
- Public education:
- Raising awareness of risk factors and promoting early intervention.
Challenges and Future Directions
- Challenges:
- Identifying and addressing emerging risk factors.
- Encouraging widespread adoption of preventive measures.
- Future directions:
- Advances in genetic research to identify high-risk individuals.
- Development of targeted therapies to mitigate specific risk factors.
Coronary atherosclerosis remains a significant global health challenge. By understanding its risk factors and implementing effective prevention strategies, we can reduce its impact and improve cardiovascular health outcomes.
