Abstract/OtherAbstract:
Management of acute pulmonary embolism (PE) has advanced considerably in the past year, and progress is expected to continue in 2013. To help determine the optimal management strategy for normotensive patients with intermediate-risk PE, the Pulmonary Embolism Thrombolysis (PEITHO) study completed enrolment of 1006 patients with evidence of right ventricular dysfunction (by echocardiography or computed tomography) plus a positive troponin test. Patients have been randomised to thrombolytic treatment with tenecteplase versus placebo, and the effects on clinical end points (death or haemodynamic collapse) assessed at 7 and 30 days. The results are expected in spring 2013; long-term follow-up is also being performed. The results of a randomised trial on ultrasound-enhanced low-dose catheter-delivered thrombolysis will also become available soon. While optimisation of treatment with vitamin K antagonists incorporating pharmacogenetic testing is still being pursued, new oral anticoagulants are entering the field of PE treatment and secondary prophylaxis. Following the successful use of rivaroxaban as single oral drug therapy in the EINSTEIN-PE trial, the approval of this drug has recently been extended to cover, apart from deep vein thrombosis, PE as well. The apixaban (AMPLIFY) and edoxaban (HOKUSAI) trials have finished recruitment of PE patients, and their results will become available shortly. In the meantime, the AMPLIFY-EXT trial showed that both the therapeutic (5 mg twice daily) and the prophylactic dose (2.5 mg twice daily) of apixaban are effective and safe for long-term secondary prophylaxis after PE. For the extended prophylaxis (after the reommended initial anticoagulation period) of the (few) patients who are unable to tolerate any form of anticoagulation, low-dose asprin may be a safe albeit moderately efficacious option, as indicated by two recent investigator-initiated trials with a total of 1224 patients.
