目的

探讨大血管闭塞性急性缺血性脑卒中(AIS-LVO)患者机械取栓术后早期血压变异性(BPV)与90 d功能预后的关系,并评估BPV对90 d良好预后的预测价值。

方法

回顾性收集2023年10月至2024年6月首都医科大学附属北京朝阳医院接受机械取栓术的100例AIS-LVO患者的临床资料,并根据术后24 h BPV中位数将患者分为低BPV组(n=72)和高BPV组(n=28)。比较2组患者的人口学和临床资料。采用皮尔逊相关系数(r)与斯皮尔曼秩相关系数(ρ)分析BPV与90 d改良Rankin量表(mRS)评分的相关性。采用多元Logistic回归分析确定BPV对90 d良好预后(90 d mRS评分≤2分)的独立预测价值,绘制受试者操作特征(ROC)曲线,评估BPV预测90 d良好预后的能力。

结果

BPV与90 d mRS评分呈显著正相关(r=0.782,ρ=0.719,P<0.001)。多元Logistic回归分析结果显示:BPV(OR=0.504,95%CI:0.360~0.694,P<0.001)和术前美国国立卫生研究院卒中量表(NIHSS)评分(OR=0.950,95%CI:0.910~0.994,P=0.035)均为90 d良好预后(mRS评分≤2分)的独立预测因素,其中,BPV升高与90 d良好预后呈显著负相关。ROC曲线分析结果显示:BPV预测90 d良好预后的曲线下面积(AUC)为0.865,敏感度为85.7%,特异度为75.0%。

结论

机械取栓术后早期BPV升高与AIS-LVO患者90 d功能预后不良密切相关。BPV可作为90 d良好预后的独立预测因子,且术后早期的BPV管理可能有助于改善患者的远期神经功能恢复。

Objective

To investigate the association between early blood pressure variability (BPV) and 90-day functional outcome in patients with acute ischemic stroke with large vessel occlusion (AIS-LVO) after mechanical thrombectomy, and to evaluate the predictive value of BPV for 90-day favorable outcome.

Methods

This retrospective study analyzed 100 AIS-LVO patients who underwent mechanical thrombectomy at Beijing Chaoyang Hospital, Capital Medical University from October 2023 to June 2024. Patients were divided into a low-BPV group (n=72) and a high-BPV group (n=28) according to the median BPV within the first 24 hours postoperatively. Demographic and clinical characteristics were compared between groups. The correlations between BPV and the 90-day modified Rankin scale (mRS) score were assessed by Pearson correlation coefficient (r) and Spearman rank correlation coefficient (ρ). Multivariable Logistic regression was used to determine the independent predictive value of BPV for a 90-day favorable outcome (90-day mRS score ≤2). Receiver operating characteristic (ROC) curve analysis was performed to evaluate the discriminative ability of BPV.

Results

BPV showed a significant positive correlation with the 90-day mRS score (r=0.782, ρ=0.719, P<0.001). Multivariable Logistic regression identified that BPV (OR=0.504, 95%CI: 0.360 – 0.694, P<0.001) and preoperative National Institutes of Health stroke scale (NIHSS) score (OR=0.950, 95%CI: 0.910 – 0.994, P=0.035) were independent predictors of a favorable outcome at 90 days, with higher BPV showing a significant negative correlation with good prognosis. ROC curve analysis demonstrated that BPV predicted 90-day favorable outcome with an area under the curve (AUC) of 0.865, a sensitivity of 85.7%, and a specificity of 75.0%.

Conclusion

Elevated early BPV after mechanical thrombectomy is closely associated with poor 90-day functional outcome in AIS-LVO patients. BPV can serve as an independent predictor of a favorable prognosis, and early postoperative BPV management may improve long-term neurological recovery.
