摘    要:目的:探讨心源性大脑中动脉栓塞导致的大面积脑梗死患者出血性转化(hemorrhagic transformation, HT)与各项血压变异性(blood pressure variability, BPV)参数之间的关系。方法选择发病后24 h内入院的单侧心源性大脑中动脉栓塞导致的大面积脑梗死患者,对入院时头颅 MRI 未发现 HT 的患者进行回顾性分析。根据发病7 d内 MRI 复查结果分为 HT 组和非 HT 组,对2组之间的各项 BPV 参数进行比较和分析,具体包括收缩压(systolic blood pressure, SBP)和舒张压(diastolic blood pressure, DBP)的初始值(initial)、平均值(mean)、最大值(max)、最小值(min)、极差(max-min)、标准差(sd)、连续变异性参数(successive variation, sv)以及 sv 的最大值(svmax)。结果共146例患者纳入分析,其中77例(52.7%)在发病7 d内发生 HT。将所有血压参数通过四分位数进行分组,多变量logistic 回归分析显示,在校正患者年龄、入院时间、基线美国国立卫生研究院卒中量表评分、充血性心力衰竭、抗血小板治疗、初始血糖、凝血酶原时间和国际标准化比率后,SBPmin、SBPmax-min、SBPsv、SBPsvmax、DBPinitial、DBPsd、DBPmax、DBPmax-min、DBPsv和 DBPsvmax与 HT 存在显著独立相关性(趋势拟然比检验 P 均<0.05)。结论较高的血压水平及变异性会增高心源性大脑中动脉栓塞后大面积脑梗死患者的 HT 风险,对于这类患者可能需要平稳和缓慢的降压治疗。

Correlation between blood pressure variability and hemorrhagic transformation in patients with cardioembolic middle cerebral artery occlusion
Abstract:Objective To investigate the correlation between hemorrhagic transformation (HT) and each parameter of blood pressure variability (BPV) in patients with massive cerebral infarction caused by cardioembolic middle cerebral artery occlusion. Methods The patients with massive cerebral infarction caused by unilateral cardioembolic middle cerebral artery occlusion admitted to hospital within 24 h after onset were selected. For patients without revealing HT with head MRI on admission were analyzed retrospectively. According to the results of MRI rescan within 7 days after onset, they were divided into either a HT group or a non-HT group. Al specific parameters of blood pressure were compared and analyzed between the 2 groups, specificaly including initial value (initial), mean value ( mean), maximum value (max), minimum value (min), maximum-minimum difference (max-min), standard deviation (sd), successive variation (sv), and maximum value of sv (svmax) of systolic blood pressure (SBP) and diastolic blood pressure (DBP). Results A total of 146 patients were enroled in the analysis, and 77 (52. 7% ) had HT within 7 d after onset. Al the blood pressure parameters were grouped by quartiles. Multivariate logistic regression analysis showed that after adjusting for age, admission time, baseline National Institutes of Health Stroke Scale score, congestive heart failure, antiplatelet therapy, initial blood glucose, prothrombin time, and international normalized ratio of the patients, SBPmin , SBPmax-min , SBPsv , SBPsvmax , DBPinitial, DBPsd , DBPmax , DBPmax-min , DBPsv , and DBPsvmax had significant independent association with and HT (likelihood ratio test of trend, al P < 0. 05). Conclusions Higher BP level and variability may increase the risk of HT in patients with massive cerebral infarction after cardioembolic middle cerebral artery occlusion. A smooth and slow antihypertensive treatment may need for these patients.
