In this episode, Dr. Valentin Fuster discusses the Garter AF trial, which evaluates the impact of screening for undiagnosed atrial fibrillation (AF) in older adults using a 14-day ECG monitor to reduce stroke risk. While the study found a marginal increase in AF diagnoses, it suggests that AI could play a crucial role in identifying high-risk patients who would benefit most from such screenings, highlighting the need for a more targeted approach in future trials.
