Using genetic testing to guide warfarin dosing can lower the risk of combined adverse events (AEs) after elective orthopedic surgery, results of the GIFT trial suggest. In this trial, investigators found that genotype-guided warfarin dosing was associated with a lower risk... [Read Article]

Study supports use of rivaroxaban to prevent VTE recurrence

Rivaroxaban (Xarelto)
Results of the EINSTEIN CHOICE study suggest rivaroxaban is more effective than, and just as safe as, aspirin for long-term anticoagulation in patients with venous thromboembolism (VTE). In this phase 3 study, patients who had completed 6 to 12 months of anticoagulant therapy were randomized to receive rivaroxaban or aspirin.... [Read Article]

Apixaban bests warfarin in real-world analysis

Warfarin tablets
An analysis of real-world data suggests elderly patients with non-valvular atrial fibrillation (NVAF) have a lower risk of stroke or systemic embolism and a lower risk of major bleeding if they receive apixaban rather than warfarin. The study also indicates that elderly NVAF patients who receive dabigatran have a similar... [Read Article]

Results from the RE-CIRCUIT trial suggest that uninterrupted dabigatran poses a lower risk of major bleeding than uninterrupted warfarin in patients with non-valvular atrial fibrillation (NVAF) who are undergoing catheter ablation. Patients who received dabigatran also had fewer serious and severe adverse events (AEs). ... [Read Article]

Results of a phase 2 trial suggest rivaroxaban and aspirin have similar safety profiles in patients with acute coronary syndrome (ACS) who are also taking a P2Y12 inhibitor. Researchers found that, overall, the risk of bleeding was similar whether patients received aspirin or rivaroxaban. ... [Read Article]

New research suggests US patients with pulmonary embolism (PE) rarely receive catheter-directed thrombolysis (CDT) or systemic thrombolysis (ST). Investigators analyzed data from more than 100,000 patients who were hospitalized for PE and found that roughly 2% received CDT or ST. ... [Read Article]
