What You Need to Know about Undiagnosed Atrial Fibrillation, an Under-Recognized Stroke Risk Factor

Saturday, 11/17 – 11:00am – 12:20pm


While early diagnosis of atrial fibrillation (AFib) can prevent cardiovascular complications, detecting it can be very challenging. Because stroke risk-assessment scores are seldom calculated in real-world settings, clinicians are often unfamiliar with their use or have insufficient time to determine a patient’s score. Nearly 30% of patients with a CHADS2 score of 3 or greater, but no diagnosed AFib, were later found to experience AFib episodes. Routine electrocardiogram (ECG) screening can help diagnose AFib, but such screening won’t detect sporadic and infrequent events that are often silent or asymptomatic. Various ECG self-monitoring apps have been shown to increase the yield of AFib detection.

What You Need to Know about Undiagnosed Atrial Fibrillation, an Under-Recognized Stroke Risk Factor will improve the early detection of AFib through use of stroke risk-assessment scores and appropriate long-term monitoring via ECG apps. Participants will also explore the possibilities for oral anticoagulation in patients with diagnosed AFib or high risk scores.

Learning Objectives

  • Identify patients who have high stroke-associated risk using novel approaches for monitoring and diagnosis
  • Use the CHA2DS2-VASc risk assessment score as a tool to determine the appropriate course of action to manage diagnosed AFib
  • Consider appropriate oral anticoagulation for patients with newly diagnosed AFib and various degrees of disease burden/stroke risk

Target Audience

This activity is intended for primary care physicians and other healthcare professionals who treat patients who have stroke-associated risk factors and may also have AFib.
