Case Study

A 67-year-old man comes to your office for a regularly scheduled visit. He has type 2 diabetes mellitus and a 40-pack-year smoking history, but he quit smoking two years ago. He takes lisinopril and atorvastatin (Lipitor); his blood pressure today is normal. His A1C and lipid panel at his last visit were within normal limits. He says that he feels well and has no neurologic complaints or any other symptoms. His father had a stroke at 68 years of age and was told it was caused by a blocked artery in his neck. The patient asks whether he should be screened for the same kind of blockage.

  • C. He should be screened for carotid artery stenosis because he is older than 65 years and has a history of cigarette smoking.

  • D. He should not be screened for carotid artery stenosis because he has no personal history of transient ischemic attack, stroke, or neurologic symptoms.

  • E. He should be screened for carotid artery stenosis with carotid duplex ultrasonography, magnetic resonance angiography, or computed tomography angiography.

2. Which of the following factors increase this patient's risk of carotid artery stenosis?

  • A. Male sex.
