Table 3, HAS-BLED Score to Estimate Bleeding Risk in Anticoagulated Patients With Atrial Fibrillation16.
| Risk Factor | Number of Points |
|---|---|
| Hypertension (uncontrolled, >160 mm Hg systolic) | 1 |
| Renal disease (Cr level >2.26 mg/dL, dialysis or transplant) | 1 |
| Liver disease (cirrhosis or bilirubin >2x ULN with AST/ALT/AP >3x ULN) | 1 |
| Stroke history | 1 |
| Prior major bleeding or predisposition to bleeding | 1 |
| Labile INR (unstable INR, time in therapeutic range <60%) | 1 |
| Elderly (age >65 years) | 1 |
| Drugs (predisposing to bleeding [aspirin, clopidogrel, NSAIDS]) | 1 |
| Alcohol (≥8 drinks/week) | 1 |
ALT = alanine aminotransferase; AP = alkaline phosphatase; AST = aspartate aminotransferase; Cr = creatinine; HAS-BLED = hypertension, abnormal liver/renal function, stroke, bleeding tendency/predisposition, labile INR, elderly (>65 years), drugs/alcohol concomitantly; INR = international normalized ratio; NSAIDs = nonsteroidal anti-inflammatory drugs; ULN = upper limits of normal.
