Need for anticoagulation and use of direct oral anticoagulants in lung transplant recipients

Limited information is available about use of direct oral anticoagulants (DOACs) in lung transplant recipients (LTRs). The purpose of this study is to describe the indications and use of long-term anticoagulation, including the safety and tolerability of DOACs, in LTRs. This was a single-center retrospective study. LTRs who received therapeutic anticoagulation were identified. Patient characteristics, indications for treatment, and complications of therapy were obtained. A total of 203 patients underwent lung transplantation of which 118 patients (58.1%) had an indication for anticoagulation. Patients with an indication for anticoagulation were older than those without (59 ± 14 years versus 48 ± 17 years, p < 0.001) and were more likely to be male (72.0% versus 50.6%, p = 0.002). Of the patients with indication for anticoagulation, 74 (62.7%) received it. Fifty-one (68.9%) of patients receiving anticoagulation were treated with DOACs. In the patients receiving anticoagulation, there were 14 major bleeding events in 13 patients, of which 3 were receiving DOACs and the remainder were receiving heparin or warfarin. The need for anticoagulation is common in LTRs for both atrial arrhythmias and venous thromboembolism. However, many patients with atrial arrhythmias do not receive anticoagulation. The use of DOACs is well tolerated and safe in LTRs.
