Which of the following is NOT a risk factor for coronary artery disease (CAD)?

Regular exercise is recognized as a protective factor against coronary artery disease rather than a risk factor. Engaging in physical activity helps to improve cardiovascular health, reduces the likelihood of developing risk factors such as hypertension and high cholesterol, and contributes to weight management. Exercise can strengthen the heart muscle, improve circulation, and enhance overall well-being.

In contrast, hypertension and high cholesterol are well-established risk factors for CAD, as they can lead to the buildup of plaque in the arteries, narrowing them and increasing the chance of heart-related issues. Additionally, having a family history of cardiovascular disease, particularly when it occurs in relatives under the age of 55, indicates a genetic predisposition that can elevate an individual’s risk for CAD.
