Instructions

For each question, please circle the best response on the answer key provided on page S84. A statement of credit will be mailed to those who successfully complete the examination with a minimum score of 75%.

1. The prevalence of atrial fibrillation (AF) in patients aged 80 years or older is:

  • 2%
  • 20%

2. The relative reduction in the risk of ischemic stroke with the oral vitamin K antagonist, warfarin, compared with aspirin is approximately:

  • 68%
  • 52%

3. Which of the following IS NOT generally considered an independent risk factor for stroke in patients with AF?

  • Hypertension
  • Older age

4. In which patients with AF will warfarin therapy be least likely to be cost-effective?

  • Recent congestive heart failure
  • Hypertension

5. Which of the following statements about anticoagulation management is/are true?

  • The majority of patients on warfarin are maintained in the therapeutic range of international normalized ratios (INRs) (2.0-3.0).
  • A and B

6. Which of the following statements about patient preferences for antithrombotic therapy are true?

  • Patients with AF who are at high risk of stroke should use warfarin regardless of their preferences.
  • A and C

7. Anticoagulation with the oral vitamin K antagonist, warfarin, is more effective than aspirin or no antithrombotic therapy to prevent ischemic stroke in patients with AF considered at moderate-to-high risk for stroke.

  • False

8. Dosing of vitamin K antagonists can be problematic and often requires coagulation monitoring. All of the following have been linked to complications EXCEPT:

  • Multiple drugs
  • Dietary vitamin K in various amounts

9. Which of the following conditions IS NOT most commonly associated with AF?

The Next Era of Anticoagulation Therapy

GOAL

To provide current information on anticoagulation therapy for the treatment of atrial fibrillation.

TARGET AUDIENCE

EDUCATIONAL OBJECTIVES

After participating in this activity, participants should be better able to:

Explain the epidemiology and initial management of new-onset atrial fibrillation.

  • Discuss the randomized trial evidence for the efficacy and safety of anticoagulants.

Describe the impact of anticoagulation therapy on costs, stroke risk, and quality of life.

  • Identify the new antithrombotic drugs currently under study and review their impact on treating atrial fibrillation.
