Which of the following is a risk factor for developing coronary artery disease?

High cholesterol levels are a significant risk factor for developing coronary artery disease (CAD). When cholesterol accumulates in the arteries, it can lead to the formation of plaques, resulting in atherosclerosis, which narrows and hardens the arterial walls. This process can restrict blood flow to the heart and increase the chance of heart attacks and other cardiovascular events. Maintaining healthy cholesterol levels is crucial for reducing the risk of CAD and promoting overall heart health.

Regular exercise, low blood pressure, and non-smoking are generally considered protective factors against coronary artery disease. In contrast to high cholesterol, these lifestyle choices and conditions contribute to cardiovascular well-being and reduction of disease risk. Regular exercise helps improve heart function and cholesterol levels, while maintaining low blood pressure and not smoking significantly lowers the likelihood of developing heart-related issues.
