Brief summary
objectives: The primary aim of APIXBRAIN-HF Trial is to explore the effects of apixaban on brain protection in patients with sinus rhythm and heart failure Primary / Secondary Endpoint 1. New occurrence of brain pathology 1) Cortical cerebral microinfarcts 2) Silent lacunar infarction 3)Progression of white matter hyperintensities 2. Secondary endpoint 1) The change of cognitive function evaluated by MMSE-2 2) Individual variable of primary endpoint 3. Safety Endpoint Evaluation 1) Cerebral microbleeds on imaging
Detailed description
This study is a double-blind, parallel-group, and randomization study. The investigators will enroll the patients with heart failure who demonstrated LV systolic dysfunction (LVEF ≤ 40%) and sinus rhythm with a CHA2DS2-VASc score ≥ 3. All patients would be randomly assigned to either the apixaban group or placebo group. Patients assigned to the apixaban group will receive 5mg bid or 2.5mg bid (patients with at least 2 of the following characteristics: aged≥80-year, bodyweight ≤60kg, serum creatinine 1.5 ml/dL) and patients in the placebo group will receive a placebo of apixaban. Both drugs will be maintained for 6 months. During the study period, all patients will be carefully monitored for thromboembolic events, including stroke. At the beginning of the study and 6 months after randomization, 3T Brain MRI and MMSE-2 test will be performed to identify changes in brain structure and cognitive function.
Interventions
