Case Study

A 65-year-old man presents to your office for a pre-employment physical examination. He has no concerning symptoms; his medical history reveals type 2 diabetes mellitus, which he controls through diet. He works in an office and rides his bicycle to work. He is single, an occasional smoker, and drinks alcohol socially. His family history is positive for type 2 diabetes and peripheral artery disease (PAD).

Case Study Questions

1. Which of the patient’s characteristics are important risk factors for PAD?

  • A. Type 2 diabetes.

  • B. Current smoking.

  • C. Age.

  • D. Family history of PAD.

2. The U.S. Preventive Services Task Force (USPSTF) recommendation on screening for PAD and assessing cardiovascular disease (CVD) risk with the ankle-brachial index (ABI) applies to which one of the following populations?

  • A. All asymptomatic adults and adolescents.

  • B. Adults at high risk for PAD or CVD.

  • C. Asymptomatic adults without a diagnosis of PAD, CVD, or severe chronic kidney disease.

  • D. Asymptomatic men 60 years and older.

  • E. Asymptomatic women 75 years and older.

3. Which one of the following statements accurately summarizes the USPSTF’s findings on screening for and treatment of PAD and assessing CVD risk with the ABI?

  • A. The USPSTF found adequate evidence that use of ABI in asymptomatic patients is accurate.

  • B. The USPSTF found inadequate evidence that early detection of PAD leads to clinically important benefits.

  • C. The USPSTF found adequate evidence that the direct harms of screening with the ABI are moderate.

  • D. The USPSTF found adequate evidence that the direct harms of treatment of PAD or CVD are significant.

  • E. The USPSTF found inadequate evidence that treatment of PAD leads to clinically important benefits.

Answers

1. The correct answers are A, B, and C. Important risk factors for PAD include older age, current smoking, high blood pressure, high cholesterol levels, type 2 diabetes, obesity, and physical inactivity. Current smoking and type 2 diabetes have the strongest association.
