BACKGROUND
To investigate the role of pregnancy-associated plasma protein A (PAPP-A) in the outcome of ischemic cerebrovascular disease.
METHODS
We analyzed the levels of PAPP-A in the transient ischemic attack (TIA) patients, ischemic stroke (IS) patients and normal control, and followed up the outcome of the patients in the following 2 years. Blood samples were drawn at admission, prior to treatment with heparins.
RESULTS
The levels of PAPP-A in TIA patients, IS patients and normal control were 4.91 (2.11, 6.48) mIU/L, 6.77 (3.31, 10.23) mIU/L and 4.25 (1.76, 5.22) mIU/L, respectively. The follow-up results of TIA patients and IS patients indicated the PAPP-A concentration in the poor prognosis group were higher than those in the good prognosis group (5.90 vs 4.46 mIU/L, P<.05, 10.06 vs 5.12 mIU/L, P<.05, respectively). Serum PAPP-A concentration emerged as a predictor of risk stratification with an OR of 1.41 and 1.25 (P<.05, P<.05).
CONCLUSIONS
Higher PAPP-A concentration has a forecasting value on prognosis in ischemic cerebrovascular disease.
背景
探讨妊娠相关血浆蛋白A（PAPP-A）在缺血性脑血管病预后中的作用。
方法
分析短暂性脑缺血发作（TIA）患者、缺血性卒中（IS）患者及正常对照者的PAPP-A水平，并对患者进行为期2年的预后随访。在入院时、肝素治疗前采集血样。
结果
TIA患者、IS患者及正常对照者的PAPP-A水平分别为4.91（2.11，6.48）mIU/L、6.77（3.31，10.23）mIU/L和4.25（1.76，5.22）mIU/L。TIA患者和IS患者的随访结果显示，预后不良组的PAPP-A浓度高于预后良好组（分别为5.90 vs 4.46 mIU/L，P<0.05；10.06 vs 5.12 mIU/L，P<0.05）。血清PAPP-A浓度可作为风险分层的预测指标，OR值分别为1.41和1.25（P<0.05，P<0.05）。
结论
较高的PAPP-A浓度对缺血性脑血管病的预后具有预测价值。
