HAS-BLED
- a tool to guide the decision to initiate anticoagulation in patients with Afib
- always compare the risk for major bleeding (calculated by the HAS-BLED score) with the risk of thromboembolic events (calculated by the CHA2DS2-VASc score) ⇒ does the benefit of anticoagulation outweigh the risk of bleeding?
- a study comparing HEMORR2HAGES, ATRIA and HAS-BLED showed superior performance of the HAS-BLED score compared to the other two scores
HAS-BLED score | ||
Hypertension |
uncontrolled BP, >160 mmHg SBP
|
1 |
Abnormal liver/renal function |
renal disease – dialysis, transplant, Cr >2.26 mg/dL or >200 µmol/L
liver disease – cirrhosis or bilirubin >2x normal or AST/ALT/AP >3x normal |

Stroke | previous stroke |

Bleeding |
prior major bleeding or predisposition to bleeding
|
1 |
Labile INR | unstable INR, time in therapeutic range <60% | 1 |
Elderly | age ≥ 65 years |
1 |
Drugs/alcohol |
medication use that predisposes to bleeding – aspirin, clopidogrel, NSAIDs
heavy alcohol use |
1 1 |
A score ≥ 3 is associated with an increased risk of major bleeding. Frequent monitoring, DOAC use, or alternatives to anticoagulation are recommended.
SMASH-U
Etiologic Classification of Intracerebral Hemorrhage – SMASH-U [Meretoja, 2012] | ||
incidence | mortality at 3 months |
|
Structural lesions (cavernous malformation, AVM) | 5% | 4 % |
Medication (warfarin, DOAC, antiplatelet therapy) | 14% | 54 % |
Cerebral Amyloid Angiopathy (CAA) |
20% | 22 % |
Systemic disease (liver, kidney disease, thrombocytopenia/thrombocytopathies) | 5% | 44 % |
Hypertension | 35% | 33 % |
Undetermined | 21% | 30% |
ABC
- in addition to clinical factors, the ABC-bleeding risk score also incorporates the biomarkers: high-sensitivity troponin T, growth differentiation factor–15, and hemoglobin
ORBIT
- ORBIT bleeding risk score has a better ability to predict major bleeding in AFib patients when compared to HAS-BLED and ATRIA risk scores. The ORBIT risk score may provide a simple, easy-to-remember tool to aid in clinical decision making [O´Brian, 2015] [Hilkens, 2017]
Older age ( >75 y) | 1 |
Reduced hemoglobin/Hct/anemia (men <13 g/dL and Hct < 40%, women < 12 g/dL and Hct < 36% ) | 2 |
Bleeding | 2 |
Insufficient kidney function (GFR < 60 mL/min/1.73 m2) | 1 |
Treatment with antiplatelets | 1 |
Maximum score | 7 |
score 0–2 – low risk ~ 2.4% / y
score 3 – medium risk ~ 4.7% / y
score ≥ 4 – high risk ~ 8.1% / y

Spetzler-Martin
- The Spetzler-Martin arteriovenous malformation (AVM) grading system assigns points for various angiographic features to predict the morbidity/mortality risk of surgery

HEMORR2HAGES
- HEMORR2HAGES score is used to stratify patients’ risk of bleeding after anticoagulation for atrial fibrillation (Afib) in conjunction with situation-specific risks
- a systemic review comparing the performance of HAS-BLED, ATRIA, and HEMORR2HAGES recommended HAS-BLED for the assessment of major bleeding risk in Afib patients
- HEMORR2HAGES had a higher diagnostic accuracy but was considered more difficult to use due to its complexity
