Clinical Trial Summary

The purpose of this study is to investigate the efficacy and safety of non-vitamin K antagonist oral anticoagulants (NOAC) in atrial fibrillation patients with intermediate stroke risk (CHA2DS2-VASc score 1 for male, 2 for female). A. Major safety results include major bleeding and clinically relevant non-major bleeding. B. Major efficacy results include strokes, systemic embolism and mortality. C. Other results include myocardial infarction, pulmonary embolism, transient ischemic attack, hospitalization, drug compliance, quality of life questionnaire (AFEQT), cognitive function (KDSQ), aging questionnaire(K-Frail) and hand grip strength.

Secondary Stroke )Ischemic stroke specifically refers to central nervous system infarction (brain, spinal cord, or retinal cell death attributable to ischemia) accompanied by overt symptoms, while silent infarction by definition causes no known symptoms. Stroke also broadly includes intracerebral hemorrhage and subarachnoid hemorrhage. Baseline

Secondary Clinically Relivant Non-Major Bleeding (CRNMB) 1. Any sign or symptom of hemorrhage (e.g., more bleeding than would be expected for a clinical circumstance, including bleeding found by imaging alone) that does not fit the criteria for the ISTH definition of major bleeding but does meet at least one of the following criteria: i. requiring medical intervention by a healthcare professional ii. leading to hospitalization or increased level of care iii. prompting a face to face (i.e., not just a telephone or electronic communication) evaluation 2. ISTH major bleeding in non-surgical patients is defined as having a symptomatic presentation and 1: i. Fatal bleeding, and/or ii.
