Etiology of Modifiable and Non-Modifiable Risk Factors for Atherosclerosis and Ischemic Heart Disease

Introduction

Atherosclerosis and ischemic heart disease (IHD) are major global health concerns, leading to significant morbidity and mortality. Understanding the risk factors can help in prevention and management.

Modifiable Risk Factors

Impact of Diet

Poor dietary habits contribute to the development of atherosclerosis. Diets high in saturated fats, trans fats, and refined carbohydrates increase LDL cholesterol and promote plaque formation.

Smoking

Smoking accelerates atherosclerosis by damaging endothelial cells, increasing inflammation, and promoting thrombogenesis.

Exercise

Regular physical activity helps regulate lipid metabolism, lower blood pressure, and improve endothelial function, reducing the risk of IHD.

Lifestyle Choices

Stress, sedentary behavior, and excessive alcohol consumption can exacerbate cardiovascular risk factors, leading to disease progression.

Non-Modifiable Risk Factors

Genetics

Family history and genetic predisposition significantly influence susceptibility to atherosclerosis and IHD.

Age

Advancing age increases arterial stiffness and plaque accumulation.

Gender

Men are at higher risk for IHD compared to premenopausal women, but postmenopausal women have an increased risk.

Conclusion

Understanding risk factors—both modifiable and non-modifiable—allows for targeted interventions to reduce disease burden and improve cardiovascular health.
