Time Trends of Aspirin and Warfarin Use on Stroke and Bleeding Events in Chinese Patients With New-Onset Atrial Fibrillation

Aspirin use increased among Chinese patients newly diagnosed with AF, with no relationship to the patient's stroke or bleeding risk. Warfarin use was very low. Given the health-care burden of AF and its complications, our study has major implications for health-care systems in non-Western countries, given the global burden of this common arrhythmia.
