Multicenter StudyRelationships of Overt and Silent Brain Lesions With Cognitive Function in Patients With Atrial Fibrillation.
Patients with atrial fibrillation (AF) have an increased risk of cognitive decline, potentially resulting from clinically unrecognized vascular brain lesions. ⋯ Patients with AF have a high burden of LNCCIs and other brain lesions on systematic brain MRI screening, and most of these lesions are clinically silent. LNCCIs were associated with worse cognitive function, even among patients with clinically silent infarcts. Our findings raise the question of MRI screening in patients with AF.

Randomized Controlled Trial Multicenter StudyInterval From Initiation of Prasugrel to Coronary Angiography in Patients With Non-ST-Segment Elevation Myocardial Infarction.
In the ACCOAST (A Comparison of Prasugrel at PCI or Time of Diagnosis of Non-ST Elevation Myocardial Infarction) trial, the prasugrel pre-treatment strategy versus placebo was associated with excess bleeding complications and no improved ischemic outcome in non-ST-segment elevation myocardial infarction (MI). Whether patients with the longest pre-treatment duration had an ischemic benefit is unknown. ⋯ In non-ST-segment elevation MI patients, the excess risk of bleeding and the absence of ischemic benefit were consistent across the quartiles of increasing duration of prasugrel pre-treatment. (A Comparison of Prasugrel at PCI or Time of Diagnosis of Non-ST Elevation Myocardial Infarction [ACCOAST]; NCT01015287).
