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

According to the analysis of the control group (AF patients who did not receive anticoagulation) at that time, some risk factors of stroke in patients with non-valvular AF were obtained, and CHADS2 scoring system was first introduced by Gage in 2001, which was considered to be a good predictor of stroke risk in these patients. Patients with a score of 0 could be treated with aspirin instead of anticoagulation, and those with a score of 1 or 2 should start anticoagulation therapy. [...]an important feature of the CAS scoring system is the ability to screen out AF patients with true high risk of TEs, who should be recommended with anticoagulation therapy immediately. According to several previous registration studies, although the situation has somehow improved in recent years, the overall anticoagulation treatment rate in China is still very low. [...]this study did not incorporate biomarkers, left atrial morphology and function, or AF load into the risk prediction model, future studies are warranted to investigate the incremental predicting efficacy for TEs risk of these factors.
