By a News Reporter-Staff News Editor at Health & Medicine Week -- Investigators publish new report on Hematologic Diseases and Conditions - Post-Thrombotic Syndrome. According to news reporting from Oslo, Norway, by NewsRx journalists, research stated, “Despite treatment of acute deep vein thrombosis (DVT) with low molecular weight heparin and warfarin, up to 50% of patients develop post-thrombotic syndrome (PTS). Our aims were to assess whether treatment of DVT with rivaroxaban would reduce the rate of subsequent PTS and improve health-related quality of life (HRQoL) as compared to conventional anticoagulation with low molecular weight heparin (LMWH)/warfarin.”

The news correspondents obtained a quote from the research from the University of Oslo, “Consecutive patients with an objectively confirmed DVT diagnosed between 2011 and 2014 and treated with either rivaroxaban or warfarin were included in this study 24 (+/- 6) months after DVT. PTS was assessed using the Patient Reported Villalta scale. HRQoL was assessed using the EQ-5D-3L and VEINES-QOL/Sym questionnaires. Total 309 patients were included, 161 (52%) treated with rivaroxaban and 148 (48%) with warfarin. Rivaroxaban-treated patients had a lower rate of PTS (45%: 95% confidence interval [CI] 37 to 52) compared to those treated with warfarin (59%: 95% CI 51 to 66, absolute risk difference 14%: 95% CI 3 to 25, odds ratio (OR) 0.6, P=. 01). The adjusted OR for development of PTS was 0.5 (95% CI: 0.3 to 0.8, P=. 01) in patients treated with rivaroxaban. HRQoL was significantly better in the rivaroxaban-treated patients. HRQoL measured by EQ-VAS (P=. 002) and VEINES-QOL/Sym (P=. 005/P=. 003) remained significantly better after adjustment. Patients treated with rivaroxaban had lower rate of PTS and better HRQoL after DVT compared to patients treated with warfarin.”

According to the news reporters, the research concluded: “However, these results should be interpreted with caution due to the limitation imposed by study design.”
