What Is Coronary Artery Disease?

Understanding Coronary Artery Disease

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Coronary Artery Disease (CAD), also known as coronary heart disease, is a condition characterized by the narrowing and hardening of the coronary arteries, which supply blood to the heart. This occurs due to the buildup of plaque and cholesterol within the arterial walls, a process known as atherosclerosis5. The progression of atherosclerosis can lead to reduced blood flow, resulting in ischemia, injury, or infarction of the heart muscle5. Major risk factors for CAD include smoking, hypertension, high LDL cholesterol levels, diabetes mellitus, age, male gender, family history, obesity, unhealthy diet, and stress5.

Risk Factors and Demographics

Diabetes mellitus is a significant risk factor for CAD, contributing to increased mortality and morbidity among diabetic patients2. Diabetic individuals often present with more severe and extensive CAD compared to non-diabetics, with a higher prevalence of multi-vessel disease8. Additionally, sex differences have been observed in CAD, with women experiencing more frequent angina and less severe ischemia compared to men, despite having less extensive CAD4.

Diagnosis and Evaluation

The evaluation of CAD can be conducted using various diagnostic modalities, including exercise ECG and coronary computed tomography angiography (CTA)5. While exercise ECG has limitations such as musculoskeletal conditions and obesity, CTA offers a more accurate assessment of coronary artery stenosis5. Clinical risk factors alone are often inadequate for predicting significant CAD, highlighting the importance of imaging techniques like CTA for accurate diagnosis3.

Treatment and Management

Management of CAD involves lifestyle modifications, pharmacological interventions, and in some cases, surgical procedures. The combination of rivaroxaban and aspirin has been shown to reduce major vascular events in patients with stable CAD, although it increases the risk of major bleeding1. Physical activity is also crucial, with higher levels of leisure time physical activity associated with improved cardiorespiratory fitness and regression of coronary atherosclerotic lesions7.

Conclusion

Coronary Artery Disease is a prevalent and serious condition influenced by various risk factors, including diabetes and lifestyle choices. Accurate diagnosis through advanced imaging techniques and effective management strategies, such as medication and physical activity, are essential in reducing the morbidity and mortality associated with CAD. Understanding the complex interplay of risk factors and treatment options is vital for improving patient outcomes.
