The effect of thrombolysis combined with prostaglandin E1 in the treatment of patients with acute pulmonary thromboembolism

Abstract

Objective To evaluate the clinical effect of thrombolysis combined with prostaglandin El (PGE1) in the treatment of patients with acute pulmonary thromboembolism (APTE).Methods According to the digital table,88 patients with APTE corresponding to thrombolytic therapy were randomly divided into the simply thrombolytic group(49 cases) and the joint PGE1 group(39 cases).The simply thrombolytic group were given conventional thrombolysis,and the joint PGE1 group were given thrombolysis combined PGE1 therapy.The levels of PaO2,PaCO2,pulmonary artery systolic pressure(PAsP),cardiac troponin I(cTNI),B-type natriuretic peptide(BNP) were monitored,and the clinical efficacy was evaluated.Results After the treatment,the levels of PAsP,cTNI,BNP of the joint PGE1 group were better than those of the simply thrombolytic group(t =2.173,2.349,2.495,all P ＜0.05).The clinical effective rate of the joint PGE1 group was 82.1％,which was significantly higher than that of the simply thrombolytic group (59.2 ％) (χ2 =5.339,P ＜ 0.05).The critical event occurrence of the joint PGE 1 group was 7.7 ％,which was significant lower than that of the simply thrombolytic group (24.5 ％) (χ2 =4.333,P ＜ 0.05).Conclusion Thrombolysis combined PGEI therapy may be more effective in reducing pulmonary artery pressure,protecting myocardia,improving the right heart function than only thrombolysis,and thus improve clinical symptoms and short-term prognosis in the APTE patients.
