Condition: Atrial Fibrillation (AF) · Stroke · Hemorrhage · Sponsor: Guangdong Provincial People's Hospital
Atrial fibrillation (AF) is the most common arrhythmia, significantly increasing the risk of stroke, heart failure, hospitalization and death in patients. Studies have shown that standardized anticoagulation can effectively reduce the risk of stroke by 64% and the risk of death by 26% in AF patients. Therefore, both European and American guidelines recommend standardized oral anticoagulation (OAC) as an important treatment strategy for stroke prevention in AF patients. However, the use of OAC may also increase the risk of bleeding in patients. Results from large AF anticoagulation randomized trials show that the annual risk of anticoagulation-related bleeding mortality is 2% to 3%. Therefore, according to the guidelines recommendations, assessing the bleeding risk is necessary in patients with anticoagulant indications. Percutaneous left atrial appendage occlusion (LAAO) is a device-based therapy that aims to prevent ischemic stroke in patients with AF. For patients with contraindications to long-term anticoagulation therapy, LAAO can be considered as an alternative strategy to oral anticoagulation (Class II B recommendation) to prevent ischemic stroke and thromboembolism. Multiple studies have shown that LAAO is non-inferior to warfarin and novel oral anticoagulants in stroke prevention for non-valvular AF patients. Age is not only a risk factor for stroke but also an important risk factor for bleeding. In the elderly population, especially those with frailty, the risk fact…
