Tech in Check: Navigating the Latest AFib Diagnostic Tools-1. Tech in Check

Video Summary

Dr. Jose Hoglar discusses the latest in atrial fibrillation (AF) diagnostic tools and management, focusing on device-detected AF and anticoagulation. The distinction between clinical and subclinical AF is blurred due to wearable tech and continuous monitoring, but remains valuable since treatment guidelines are based on clinical AF. Subclinical AF is prevalent in patients with pacemakers or ICDs, even without symptoms, and poses a varying stroke risk depending on AF duration. Short episodes pose less risk, while longer episodes may indicate a higher stroke risk. The ASSERT study highlighted that subclinical AF of greater than 24 hours is notably riskier. The guidelines now recommend anticoagulation based on absolute thromboembolic risk rather than solely CHAS-VASc score, using a nuanced approach to balance stroke risk and anticoagulation bleeding risks. Finally, anticoagulation recommendations for subclinical AF have a lower class than for clinical AF due to a generally lower stroke risk.
