What is the target level of LDL cholesterol for reducing coronary artery disease risk?

• A. Less than 160 mg/dL
• B. Less than 130 mg/dL
• C. Less than 100 mg/dL
• D. Less than 200 mg/dL

Answer: (C)

The target level of LDL (low-density lipoprotein) cholesterol for reducing the risk of coronary artery disease is set at less than 100 mg/dL. This threshold has been established based on extensive research demonstrating that lower levels of LDL cholesterol significantly decrease the likelihood of plaque buildup in the arteries, which can lead to atherosclerosis and other cardiovascular diseases.

Maintaining LDL cholesterol at or below this level is particularly important for individuals with existing cardiovascular risk factors, as high levels of LDL can contribute to the development of heart disease. The rationale behind targeting this specific level is that it not only provides a preventive measure against heart problems but also improves overall cardiovascular health.

Other levels presented, such as less than 130 mg/dL or less than 160 mg/dL, may be considered acceptable or intermediate goals, but they do not offer the same level of protection against coronary artery disease as aiming for less than 100 mg/dL does. This is why the value of less than 100 mg/dL is recommended as the optimal target in clinical settings aimed at risk reduction for coronary artery disease.
