Hypertension: systolic blood pressure >160 mm Hg; Abnormal renal function: presence of chronic dialysis or renal transplantation or serum creatinine ≥200 μmol/L; abnormal hepatic function: chronic hepatic disease or biochemical evidence of significant hepatic derangement (eg, bilirubin >2× upper limit of normal, in association with aspartate aminotransferase/alanine aminotransferase/alkaline phosphatase >3× upper limit of normal, etc); ‘Bleeding’ refers to previous bleeding history and/or predisposition to bleeding (eg, bleeding diathesis, anemia); ‘Labile INRs’ refer to unstable/high INRs or poor time in therapeutic range (eg, <60%); Drugs/alcohol use refers to concomitant use of drugs, such as antiplatelet agents, nonsteroidal anti-inflammatory drugs, alcohol abuse, etc.
