A high HAS-BLED score is not a reason to withhold anticoagulation. Also, when compared to HAS-BLED, other bleeding risk scores that did not consider 'labile INR' would significantly underperform in predicting bleeding on warfarin, and would often inappropriately categorise many patients who sustained bleeds as 'low risk'. [38]
Side effects may include bleeding, most commonly from the nose, gastrointestinal tract (GI) or genitourinary system. [2] Compared to the risk of bleeding with warfarin use, direct factor Xa inhibitors have a higher risk of GI bleeding, but lower risk of bleeding in the brain. [2]
Bleeding risk may be increased in people on hemodialysis. [49] Another score used to assess bleeding risk on anticoagulation, specifically Warfarin or Coumadin, is the ATRIA score, which uses a weighted additive scale of clinical findings to determine bleeding risk stratification. [50]
In a newly diagnosed non-anticoagulated AF patient, the physician may avoid a ‘trial of warfarin’ (which may expose patients to increased stroke risk during the initial inception phase, with suboptimal anticoagulation control [9]) and make an informed decision between patients likely to do well on a VKA (SAMe-TT 2 R 2 score 0–2) or where ...
Tecarfarin is a vitamin K antagonist under development for use as an anticoagulant. [2] A Phase II/III clinical trial in 607 people, comparing it to the established vitamin K antagonist warfarin, found no difference in quality of anticoagulation or side effects between the two drugs in the overall population. [3]
Mixed evidence exist on the comparison between GARFIELD-AF bleeding score over the HAS-BLED. [ 5 ] [ 6 ] 2020 ESC guidelines on atrial fibrillation recommend assessment of bleeding risk in AF using the HAS-BLED bleeding risk schema as a simple, easy calculation, [ 7 ] whereby a score of ≥3 indicates "high risk" and some caution and regular ...
[106] [107] For dental procedures with a higher risk of bleeding complications (i.e. complex extractions, adjacent extractions leading to a large wound, or more than three extractions), the recommended practice is for the patient to miss or delay a dose of their DOAC before such procedures to minimize the effect on bleeding risk. [108]
The normal range for a healthy person not using warfarin is 0.8–1.2, and for people on warfarin therapy an INR of 2.0–3.0 is usually targeted, although the target INR may be higher in particular situations, such as for those with a mechanical heart valve. If the INR is outside the target range, a high INR indicates a higher risk of bleeding ...
