Which cholesterol level is considered at risk for heart disease?

• A. Less than 150 mg/dL
• B. 200-239 mg/dL
• C. 240 mg/dL or higher
• D. All of the above

Answer: (C)

A cholesterol level of 240 mg/dL or higher is identified as a risk factor for heart disease. At this level, individuals are categorized as having high cholesterol, which increases the likelihood of developing cardiovascular problems. Higher levels of cholesterol can lead to the buildup of plaque in arteries, narrowing them, and making it more difficult for blood to flow. This can ultimately result in heart attacks or strokes.

In contrast, levels below 200 mg/dL are generally considered desirable. While the range from 200-239 mg/dL indicates borderline high cholesterol, it does not classify someone as at-risk to the same degree as the 240 mg/dL threshold. Thus, maintaining cholesterol levels below 200 mg/dL is essential for heart health, and those with levels of 240 mg/dL or higher are advised to take appropriate measures to reduce it and therefore lower their risk for heart disease.
