For individuals over 40 years old, there is MODERATE risk of developing coronary heart disease when cholesterol is greater than ____ mg/dL.

Total cholesterol levels help estimate coronary heart disease risk because higher circulating cholesterol promotes atherosclerotic plaque in the arteries. As the total cholesterol rises, risk categories shift toward greater risk. The commonly used cutoffs are: under 200 mg/dL is desirable, 200–239 mg/dL is borderline, and 240 mg/dL or higher indicates a higher risk category. For individuals over 40, crossing the 240 mg/dL threshold signals that CHD risk is elevated to a moderate level, which is why 240 mg/dL is the key value. Values around 200 or 220 fall into border‑line ranges, while 260 mg/dL would suggest even higher risk and typically prompt more aggressive management.
