Four DOACs, four dosing schemes, and low adherence complicate stroke prevention. Dr. Barnes reviews dose-reduction criteria and the discontinuation rates that clinicians must address.

The move from warfarin to DOACs reduced monitoring burden and expanded treatment, but it also reduced patient contact with the health care team. Dr. Barnes weighs the trade-offs.

Cardioembolic stroke produces more severe strokes, greater disability, higher mortality, and frequent recurrence than other subtypes. Dr. Barnes reviews the outcome data that make prevention a clinical priority.

Welcome back to another AJMC Insights series. In "Cardioembolic Stroke in AFib: Defining the Subtype and Its Mechanism," Dr. Barnes joins us to open the series on cardioembolic stroke in atrial fibrillation.

This study found that switching from a conventional troponin assay to a high-sensitivity troponin assay resulted in changes to diagnosis patterns and stress testing trends.
