A 52-year-old man requests a coronary-artery calcium (CAC) scan for assessment of his risk of coronary events after seeing an advertisement from a local facility that offers the test. He has no symptoms of cardiac disease, has never smoked, and is not overweight, but he does not exercise regularly. His father, who was a heavy smoker, had a fatal myocardial infarction at 45 years of age. The patient's blood pressure is 130/85 mm Hg. His total cholesterol level is 220 mg per deciliter (5.7 mmol per liter), and his low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol levels are 160 mg per deciliter (4.1 mmol per liter) and 38 mg per deciliter (1.0 mmol per liter), respectively. His fasting blood glucose level is 92 mg per deciliter (5.1 mmol per liter). What would you advise regarding CAC scanning?
