The score for patients with atrial fibrillation includes the embolism score and the bleeding score. The embolism score is the CHA2DS2 score, which is defined as 1 if the patient has heart failure, hypertension, is older than 65 years old, or has had a previous stroke, or has symptoms of diabetes mellitus, and 2 if the patient has had a stroke. The HAS-BLED score refers to the bleeding score of patients with heart failure and atrial fibrillation, if they have hypertension or poor coagulation, or combined with renal insufficiency, and have previous bleeding, each month is counted as 1 point, which corresponds to the risk of bleeding and the risk of embolism. It should be judged by the doctor’s comprehensive judgment, not the patient himself taking anticoagulant drugs.
