Retrograde coronary blood flow during cardiopulmonary resuscitation in swine: intracoronary Doppler evaluation.

abstract：BACKGROUND:Several non-vitamin K antagonist oral anticoagulant (NOAC) alternatives to warfarin are available for stroke prevention in atrial fibrillation (AF). We aimed to describe the factors associated with selection of NOACs versus warfarin in patients with new onset AF. METHODS:The ORBIT-AF II study is a national,...
