Study gives bleeding risk estimates for VTE patients on anticoagulants



The analysis indicates that there is “a clinically meaningful difference in long-term risk for anticoagulant-related major bleeding among patients with a first unprovoked VTE stratified according to presence or absence of the following risk factors: age older than 65 years, creatinine clearance less than 50 mL/min, history of bleeding, concomitant use of antiplatelet therapy, and hemoglobin level less than 100 g/L,” the authors said.

For example, the researchers found that the incidence of major bleeding was higher among those older than 65 years, compared with younger patients (incidence rate ratio, 1.84 with VKAs and 2.92 with DOACs), and among those with creatinine clearance less than 50 mL/min (IRR, 2.83 with VKAs and 3.71 with DOACs).

The case-fatality rate of major bleeding was 8.3% with VKAs and 9.7% with DOACs.

The study received funding from the Canadian Institutes of Health Research. Some of the coauthors are employees of or have financial ties to pharmaceutical companies. Mr. Khan, Dr. Rodger, and Dr. Fang had no relevant disclosures.
