Novel Anticoagulant Treatment for Pulmonary Embolism with Direct Oral Anticoagulants Phase 3 Trials and Clinical Practice.

Anticoagulant therapy is the cornerstone of therapeutic management in acute venous thromboembolism (VTE), consisting of pulmonary embolism and deep vein thrombosis. Direct oral anticoagulants (DOACs) have become the standard of care because of their good safety profile and ease of use in clinical practice. Indeed, phase 3 randomized trials (AMPLIFY, EINSTEIN, RECOVER, and HOKUSAI studies) showed that DOACs provided a similar efficacy and a better safety than conventional treatment with parenteral heparin with overlapping loading dose of vitamin K antagonists in acute VTE therapeutic management. The results of published data from real-world registries confirm the safety and efficacy of DOACs demonstrated in the phase 3 trials.
