What is a common risk factor for coronary artery disease?

• A. Regular exercise
• B. High cholesterol levels
• C. Balanced diet
• D. Low stress levels

Answer: (B)

High cholesterol levels are indeed a common risk factor for coronary artery disease (CAD). Cholesterol is a type of fat found in the blood, and while the body needs it to some extent for various functions, elevated levels—especially of low-density lipoprotein (LDL) cholesterol—can lead to the buildup of plaque in the arteries. This buildup constricts blood flow and can eventually lead to the development of CAD, which can result in chest pain, heart attacks, and other serious cardiovascular issues.

It's important to maintain a balanced range of cholesterol levels through lifestyle choices such as diet and exercise. In contrast, regular exercise, a balanced diet, and low stress levels are protective factors that can help reduce the risk of CAD, highlighting the importance of lifestyle management in cardiovascular health.
