    摘要:

    目的 探讨早期血压变异性(BPV)预测急性缺血性卒中(AIS)静脉溶栓(IVT)后发生症状性颅内出血(sICH)风险的价值。方法 纳入2012至2016年的发病4.5 h内行重组组织型纤溶酶原激活剂IVT且临床资料完整的AIS患者。依据溶栓治疗后48 h内头颅CT或MRI结果及NIHSS评分变化分为sICH组(22例)和非sICH组(157例)。采用单因素t、χ2检验和多因素Logistic回归分析2组sICH危险因素的差异性。进一步分别将24 h收缩压标准差(24hSBPsd)和24h舒张压标准差(24hDBPsd)以四分位数分为4组,以最低四分位组为参照组,其余组分别与参照组比较。结果 单因素分析表明,sICH组年龄、纤维蛋白原(FIB)、吸烟史、24hSBPsd、24hDBPsd均高于非sICH组(均P<0.05)。多因素Logistic回归分析表明,sICH组年龄(OR 3.7,5%CI 1.089~8.920)、吸烟史(OR 2.3,5%CI 1.042~8.257)及24hSBPsd(OR 4.5,5%CI 1.397~12.237)均仍高于非sICH组(均P<0.05),而2组之间FIB、24hDBPsd比较,差异无统计学意义(P>0.05)。校正年龄、吸烟史危险因素后,最高四分组24hSBPsd、24hDBPsd发生sICH风险分别是最低四分位组的10.882倍(95%CI 2.088~56.717)、6.025倍(95%CI 1.550~23.417),差异均有统计学意义(P<0.05)。结论 早期BPV越大,发生IVT后sICH风险越高,以收缩压变异性的影响更明显。

    Abstract:

    Aim To explore the value of early blood pressure variability (BPV) in predicting the risk of symptomatic intracerebral hemorrhage (sICH) after intravenous thrombolysis (IVT) in acute ischemic stroke (AIS). Methods AIS patients were collected who received recombinant tissue plasminogen activator IVT within 4.5 hours of onset from 2012 to 2016 with complete clinical data. According to skull CT or MRI findings and NIHSS scores within 48 hours after IVT therapy, the patients were divided into sICH group (22 cases) and non-sICH group (157 cases). The differences of sICH risk factors between the two groups were analyzed by single factor t test, χ2 test and multivariate Logistic regression analysis. The 24-hour systolic blood pressure standard deviation (24hSBPsd) and 24-hour diastolic blood pressure standard deviation (24hDBPsd) were further divided into four groups in quartiles, with the lowest quartile group as the reference group, and the rest groups were compared with the reference group, respectively. Results Univariate analysis showed that age, fibrinogen (FIB), smoking history, 24hSBPsd and 24hDBPsd in sICH group were higher than those in non-sICH group (all P<0.05). Multivariate Logistic regression analysis showed that age (OR 3.7,5% CI 1.089-8.920), smoking history (OR 2.3,5% CI 1.042-8.257) and 24hSBPsd (OR 4.5,5% CI 1.397-12.237) in sICH group were still higher than those in non-sICH group (all P<0.05); There was no significant difference in FIB and 24hDBPsd between the two groups (P>0.05). After adjusting for risk factors of age and smoking history, the risks of sICH in 24hSBPsd and 24hDBPsd of the highest quartile group were 10.882 times (95%CI 2.088-56.717) and 6.025 times (95%CI 1.550-23.417) higher than those of the lowest quartile group, respectively, and the differences were statistically sigificant (P<0.05). Conclusion The higher the early BPV, the higher the risk of sICH after IVT, and the more obvious the influence of systolic blood pressure variability.
