What is a common risk factor for developing coronary artery disease?

High LDL cholesterol levels are recognized as a significant risk factor for developing coronary artery disease (CAD). Low-density lipoprotein (LDL) cholesterol is often referred to as "bad" cholesterol because it can build up in the walls of arteries, leading to atherosclerosis—a condition characterized by the narrowing of arteries due to plaque formation. This narrowing increases the risk of heart-related issues, including heart attacks and other forms of cardiovascular disease.

In contrast, low blood pressure is typically considered a positive cardiovascular health indicator and does not contribute to the development of CAD. Regular physical exercise is associated with a lower risk of heart disease, as it helps maintain healthy cholesterol levels, manage weight, and improve overall vascular health. High vitamin D levels are not established as a risk factor for CAD; rather, they may have various health benefits, but their relationship to heart disease is still being studied.

Understanding these factors helps emphasize the importance of monitoring cholesterol levels as part of cardiovascular risk assessment and management strategies.
