摘  要:目的 探讨伴高同型半胱氨酸血症的高血压(H型高血压)患者血栓前状态的特点以及高同型半胱氨酸对高血压患者远期血栓事件的影响.方法 研究纳入2003年10月至2009年11月华山医院宝山分院门诊或住院的高血压2级患者220例,其中H型高血压患者110例即为H型高血压组,单纯型高血压患者110例即为单纯型高血压组.检测两组患者血栓前状态的实验室指标,包括纤维蛋白原定量(FIB)、血浆黏度、血栓调节蛋白(TM)、血小板颗粒膜糖蛋白(GMP-140)、凝血酶原片段1 +2(F1+2)、D-二聚体(D-Dimer)、抗凝血酶原Ⅲ(AT-Ⅲ).多元线性逐步回归分析高同型半胱氨酸与血栓前状态实验室指标的相关性.对所有患者进行长期随访,终点包括动脉血栓事件和静脉血栓事件.采用Cox比例风险模型对可能影响血栓事件的指标进行多因素回归分析,采用Kaplan-Meier生存曲线计算无血栓事件生存率,生存分析采用Log-rank检验.结果 H型高血压组患者TM、GMP-140和F1+2均明显高于单纯型高血压组[分别为(4.8±1.2) μg/L比(4.5±1.0)μg/L(P=0.045)、(18.8±3.2) μg/L比(17.1 ±4.3) μg/L(P=0.001)和(1.2±0.4)nmol/L比(1.0±0.6)nmol/L(P =0.004)],而AT-Ⅲ则明显低于单纯型高血压组[(95.3±10.4)%比(98.6±10.6)%,P =0.021].两组间FIB、血浆黏度、D-Dimer差异无统计学意义.多元线性逐步回归分析显示血浆同型半胱氨酸水平与年龄、女性、TM呈正相关(分别为β=0.217、P=0.04,β=5.667、P=0.001,β=2.341、P=0.003),与AT-Ⅲ呈负相关(β=-0.199、P=0.011).经远期随访(中位随访时间为85个月),多因素Cox比例风险分析显示高龄、高同型半胱氨酸是高血压患者发生血栓事件的独立危险因素(分别为OR 1.046、95%CI1.013 ~ 1.082,OR 1.052、95%CI1.027 ~1.078).Log-rank检验H型高血压组和单纯型高血压组间无血栓事件生存率差异有�Objective To evaluate the association between homocysteine level and prethrombotic status and long-term thromboembolic events in patients with primary hypertension.Methods Results between 110 hypertensive patients with elevated homocysteine (HCY) level were compared with 110 hypertensive patients with normal HCY level,which were enrolled from October 2003 to November 2009.Fibrinogen (FIB),viscosity,thrombomodulin (TM),granule membrane protein (GMP-140),prethrombin F1 +2 fragment (F1 +2),D-dimer fragment (D-Dimer) and antithrombin Ⅲ (AT-Ⅲ) were measured and correlated to HCY and prethrombotic state.The endpoints of the study were arterial and venous thromboembolic events.The variables linked with arterial and venous thromboembolic events were included in Cox proportional hazard models.The event-free survival was illustrated with Kaplan-Meier survival curves and compared by the Log-rank test.Results The patients were followed up for 8-122 months (median follow-up time was 85 months).Compared with hypertensive patients with normal HCY,the plasma level of TM ((4.8 ± 1.2) μg/L vs.(4.5 ± 1.0) μg/L,P =0.045),GMP-140((18.8 ±3.2) μg/L vs.(17.1 ±4.3) μg/L,P =0.001),F1+2 ((1.2 ±0.4) nmol/L vs.(1.0 ±0.6) nmol/L,P =0.004) were significantly higher while the plasma level of AT-Ⅲ ((95.3 ± 10.4) % vs.(98.6 ± 10.6) %,P =0.021)was significantly lower in hypertensive patients with elevated HCY level.FIB,viscosity of plasma and D-dimer were similar between the two groups.Multiple regression analyses indicated that HCY level was negatively correlated with AT-Ⅲ(3 =-0.199,P =0.011) and positively correlated with age (3 =0.217,P =0.04),female gender (β =5.667,P =0.001) and TM (β =2.341,P =0.003).Cox multivariate analysis revealed that age and HCY level were independent prognostic risk factors of thromboembolic events (OR 1.046,95% CI 1.013-1.082,OR 1.052,95% CI 1.027-1.078,respectively) (all P 〈 0.05).Kap
