Abstract:
Objective To compare the application effect of different doses of rivaroxaban on anticoagulation therapy in patients with pulmonary thromboembolism(PTE)during maintenance period,and to evaluate its benefit-risk.Methods The patients with PTE were divided into conventional-dose group and low-dose group according to the cohort method.Conventional-dose group were given of rivaroxaban 15 mg,twice a day and changed to 20 mg once a day after 3 weeks;low-dose group were given rivaroxaban 10 mg twice a day and changed to 15 mg once a day after 3 weeks,and the anticoagulation treatment time in both groups was ≥ 3 months.The clinical efficacy in the two groups was recorded.Serum indicators[D-dimer(D-D),N-terminal pro-brain natriuretic peptide(NT-proBNP),cardiac troponin Ⅰ(cTn Ⅰ)]and liver-kidney function[glutamic-pyruvic transaminase(GPT),glutamic-oxaloacetic transaminase(GOT),blood urea nitrogen(BUN),creatinine(Cr)]were compared before treatment and after 3 months of treatment.The patients were followed up for 3 months after treatment,and the endpoint events such as PTE recurrence and death and the bleeding events were recorded in the two groups.Results There were 42 cases in conventional-dose group,44 cases in low-dose group.After 3 months of treatment,the total effective rates in low-dose group and conventional-dose group were both 100.00%,with no significant difference(P>0.05).After 3 months of treatment,serum D-D levels in low-dose group and conventional-dose group were(0.31±0.08)and(0.29±0.07)mg·L-1,NT-proBNP levels were(125.49±24.16)and(121.39±22.08)ng·L-1,cTn Ⅰ levels were(0.02±0.00)and(0.02±0.00)μg·L-1,all with significant differences(all P>0.05).There were no significant changes in GPT,GOT,BUN and Cr in the two groups before and after treatment(all P>0.05),and there were no statistically significant differences between the two groups(all P>0.05).The total incidences of bleeding events during follow-up was 6.82%in low-dose group and was 23.81%in conventional-dose group(P<0.05).Conclusion Compared with conventional-dose rivaroxaban,low-dose rivaroxaban has similar anticoagulant effect,but the latter one can better reduce the risk of bleeding events in patients with PTE.
