急性肺血栓栓塞患者血清心肌酶的变化

目的 比较急性大面积、次大面积、非大面积肺血栓栓塞症(PIE)患者治疗前与治疗后各时间段心肌酶的变化,及其与估测肺动脉压力、右心功能及预后的关系.方法 519例PIE患者来自北京24家医院参与的国家"十五"科技攻关课题--肺栓塞规范化诊治方法的研究.根据2001年5月中华医学会呼吸病学分会制定的<肺血栓栓塞症的诊断与治疗指南(草案)>的诊断标准确定大面积、次大面积、非大面积肺栓塞患者.大面积、次大面积患者采用溶栓治疗,非大面积肺栓塞患者采用抗凝治疗.按中心随机方法将患者分组,应用尿激酶和重组组织型纤溶酶原激活剂及普通肝素和低分子肝素.结果 (1)大面积PTE患者治疗前血清CPK、LDH水平明显高于次大面积、非大面积PTE患者(P<0.01);(2)3组间及各组治疗前、后血清CK-MB水平差异无统计学意义;(3)519例PIE患者45例估测肺动脉压≥80 mmHg者,血清LDH升高24例(54.4%),P<0.01;169例治疗前存在右心运动功能减弱者,血清LDH升高者68例(40.2%),P=0.049;48例预后不良者血清LDH升高者15例(30.8%),P=0.039.结论 ①急性PTE患者可出现血清CPK、LDH水平升高,不伴有血清CK-MB的异常.②血清LDH水平与患者估测肺动脉压力、右心功能及预后密切相关.

Changes of the serum myocardial enzymes in patients with acute pulmonary thromboembolism

Objective To explore the changes of the serurn cardiac enzymes in patients with acute massive pulmonary thromboembolosm(PIE),sub-massive PTE and non-massive FIE between pre-therapy and past-therapy and its relationship.Method The prospective multi-centres trial included 519 patients with confirmed PTE from 24 joint hospitals in Beijing,consisting of 54 massive FIE,195 sub-massive PTE and 270 non-massive PIE.Thrombolytic treatment was used in massive and sub-massive PTE patients with employment of urokinase and recombinant tissue plasminogen activator(rt-PA),and anti-coagulative therapy with unfractionated heparin and low molecular heparin was used in non-massive PTE.Results(1)The values of serum CPK and LDH in massive PTE patients before therapeutical intervention were obfiously higher than those in sub-massive and non-massive PTE patients(P<0.01);(2)Of 45 patients with high pulmonary pressure,24(54.4%)patients had high serum LDH(P<0.01).Of 169 patients with right ventrieular dysfunction,68(40.2%)ones has high serum LDH(P=0.049).Of 48 patients suffered from poor prognosis,15(30.8%)ones had high serum.LDH(P=0.039).Conclusions ①The vMues of serum CPK and LDH in acute PTE patients increase without elevation of CK-MB.②Serum LDH associates with pulmonary presure,right ventrieular function and prognosis.
