Abstract:
Direct oral anticoagulants (DOACs) are being increasingly used in the clinical setting for patients at risk of venous thromboembolism (VTE) and/or stroke. These medications offer valued benefits for long-term use, including a fast onset of anticoagulation, fixed anticoagulation profile (and consequent prescription of specified doses) and no requirement for routine monitoring. Apixaban is a selective factor Xa inhibitor, approved for use in the prevention of stroke in patients with nonvalvular atrial fibrillation and in the prevention and treatment of acute VTE. Like many of the DOACs, it has a fast onset of action and works to deliver predictable coagulation results. Multiple randomized controlled trials including ARISTOTLE and AMPLIFY have shown apixaban to be noninferior to vitamin K antagonists in the prevention of stroke and VTE, with a good safety profile. This article aims to review the use of apixaban for the prevention and treatment of thromboembolic disease, highlighting the key study results that have led to its current licensing and use.

Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
