Comments on “A simple and easily implemented risk model to predict 1-year ischemic stroke and systemic embolism in Chinese patients with atrial fibrillation”

Risk stratification for ischemic stroke is essential for patients with atrial fibrillation(AF)before the consideration of anticoagulation therapy.According to current AF management guidelines,about 90%of AF patients should receive anticoagulation therapy,and risk of stroke death in AF patients was around 68%.It is thus of importance to precisely define the patients who are in urgent need of anticoagulation therapy.In this context,study results from Ma et al[1]published in this issue could be helpful to precisely define the AF patients who are at real risk of stroke.The study aims to develop an accurate and easy-to-use predictive model for the 1-year risk of thromboembolic events(TEs),including ischemic stroke and systemic embolic events,in Chinese patients with AF.
