The Difference

<p>The aim of this meta-analysis was to systematically evaluate the efficacy and safety of novel oral anticoagulants and vitamin K antagonists in the treatment of venous thromboembolism. A total of 6 studies met the inclusion criteria and a total of 19,350 patients with venous thromboembolism were included. Among them, rivaroxaban (3 RCTs, n=90/3,449/4,832); dabigatran (2 RCTs, n=200/2,539); edoxaban (1 RCT, n=8,240). The results of meta-analysis showed that the total bleeding rate after treatment with the vitamin K antagonist group was higher than with the new oral anticoagulant group (OR=0.82, 95% confidence interval 0.75-0.90, p&lt;0.0001), and the difference was highly statistically significant. Overall, new oral anticoagulants are compara-ble to vitamin K antagonists, but new oral anticoagulants can reduce the occurrence of bleeding events and the safety was superior to vitamin K antagonists.</p>

Acute Venous Thromboembolism

Abstract Background New direct oral anticoagulants (NOACs), as a preferable treatment option for acute venous thromboembolism (VTE) have been recommended with practical advantages as compared to Vitamin K antagonists (VKAs) in clinical practice. Purpose In our study, we performed a meta-analysis to determine the efficacy and safety of NOACs vs. VKAs in patients with different age, sex and renal function for the treatment of VTE. Methods Electronic databases (accessed October 2019) were systematically searched to identify RCTs evaluating apixaban, dabigatran, edoxaban, and rivaroxaban versus VKAs for the treatment of acute venous thromboembolism. Results NOACs was associated with a borderline higher efficacy in female (OR 0.79, 95% CI 0.62–1.02), and a significantly higher efficacy in patients with age more than 75 (OR 0.51, 95% CI 0.32–0.80) and creatinine clearance less than 50 mL/min (OR 0.57, 95% CI 0.32–0.99). NOACs also show advantage in terms of major or clinically relevant non-major bleeding in male (OR 0.72, 95% CI 0.60–0.86), and patients with creatinine clearance more than 50 mL/min (OR 0.75, 95% CI 0.67–0.84). Conclusions NOACs have exhibited clinical preference among patients with acute VTE as compared to VKA with significantly decreased thrombosis events and lower bleeding complications, especially in patients with age more than 75 and creatinine clearance less than 50 mL/min.
