What is one of the primary risk factors for coronary artery disease?

High cholesterol is indeed one of the primary risk factors for coronary artery disease (CAD). Elevated levels of cholesterol, particularly low-density lipoprotein (LDL) cholesterol, can lead to the buildup of plaques in the coronary arteries, a condition known as atherosclerosis. This buildup narrows the arteries, restricts blood flow to the heart, and increases the risk of heart attacks and other cardiovascular events. The management of cholesterol levels through diet, exercise, and medication is a crucial aspect of preventing CAD and promoting heart health.

On the other hand, low blood pressure is generally not associated with increased risk for coronary artery disease; in fact, it is often considered beneficial for cardiovascular health. Increased calcium levels can be associated with other health issues, but they are not a primary risk factor for CAD. A high-fiber diet is generally encouraged as it supports heart health and can help lower cholesterol levels, but it does not increase the risk of coronary artery disease.
