妊娠期高血压疾病凝血指标变化

目的 探讨妊娠期高血压疾病患者凝血指标变化的意义.方法 收集66例妊娠期高血压疾病患者(妊娠期高血压组)及70例正常妊娠晚期孕妇(对照组),行血小板计数(PC)、平均血小板体积(MPV)、凝血酶原时间(PT)、部分凝血活酶时间(APTT)、纤维蛋白原(FIB)、D-二聚体(D-D)检测.结果妊娠期高血压组与对照组比较,PC(178.32±51.08) × 10~9/L比(186.17±40.02)× 10~9/L]、PT(10.54±0.54)s比(11.07±0.49)s]、APTT(26.23±3.12)s比(28.08±4.31)s]显著下降(P<0.05或<0.01);FIB(5.34±0.68)g/L比(4.02±0.73)g/L]、MPV(11.10±2.31)fl比(8.95±1.37)fl]、D-D(0.46±0.27)mg/L比(0.18±0.19)mg/L]显著增加(P<0.01).重度子痫前期患者与轻度子痫前期患者比较,FIB、D-D显著增加(P<0.01).早发型子痫前期患者与晚发型子痫前期患者比较,PT明显缩短(P<0.05),FIB、D-D明显增加(P<0.05或<0.01).结论 妊娠期高血压疾病呈明显高凝状态;早发型子痫前期患者较晚发型子痫前期患者高凝状态和凝血功能障碍更严重.

Changes of coagulation function of pregnancy induced hypertension

Objective To investigate the changes of the hemostatie coagulation markers in pregnancy induced hypertension (PIH)and significance.Methods The blood samples were collected from 70 normal pregnant women (control group) and 66 pregnant women with PIH (PIH group).Platelet count (PC), mean platelet volume ( MPV ), prothrombin lime (PT), partial thromboplastin time (AFIT), fibrinogen (FIB),D-dimmer (D-D)were measured.Results Compared with the control group,the level of PC,PT, APTT in the PIH group were significantly decreased (178.32±51.08) × 10~9/L vs (186.17±40.02) × 10~9/L, (10.54±0.34) s vs(11.07±0.49) s, (26.23±3.12) s vs(28.08±4.31) s](P<0.05 or <0.01), while those of FIB,MPV,D-D were significantly increased (5.34±0.68) g/L vs (4.02±0.73) g/L, (11.10 ± 2.31 ) fl vs (8.95 ± 1.37) fl, (0.46 ± 0.27) mg/L vs (0.18 ± 0.19) mg/L](P < 0.01 ).The levels of FIB and D-D were significantly increased in severe preeclampsia (34 cases) than those in mild preeclampsia (32 cases) (P < 0.01 ).The level of PT was lower and FIB, D-D were increased in early onset preeclampsia ( 31 cases ) than those in late onset preeclampsia (35 cases) (P < 0.05 or < 0.01 ).Conclusions There is hypercoagulative state in pregnant women with PIH.The disorders of coagulation function may be more severe in early onset preeelampsia than those in late onset preeclampsia.
