急性脑梗死多模态MRI表现及脂蛋白相关磷脂酶A2、胱抑素C与短期预后的相关性研究

Multimodal MRI manifestations and correlation between lipoprotein-associated phospholipase A2,cystatin C and short-term prognosis in acute cerebral infarction

目的探索急性脑梗死(ACI)磁共振成像(MRI)表现及脂蛋白相关磷脂酶A2(Lp-PLA2)、胱抑素C(Cys C)与短期预后的相关性。方法选取2022年1月1日至2023年1月1日我院神经内科收治的110例ACI患者为研究对象,收集患者的临床资料、多模态MRI图像,检测患者血清Lp-PLA2、Cys C水平。根据患者自发病后90 d的改良Rankin量表(mRS)评分将其分为预后良好组及预后不良组,分析MRI表现及Lp-PLA2、Cys C水平对短期预后不良的预测价值。结果预后良好组及预后不良组患者在发病至入院时间、入院时美国国立卫生院卒中量表(NIHSS)评分、高血压或糖尿病、冠心病或心房颤动方面差异具有统计学意义(P<0.05)。预后不良组缺血半暗带、HV阳性、皮质-皮质下梗死、大穿通支梗死、小穿通支梗死、双侧前循环梗死、后循环梗死、前-后循环梗死、大脑中动脉(MCA)狭窄或闭塞、颈内动脉(ICA)和MCA均狭窄或闭塞、大脑后动脉(PCA)或椎动脉(VA)狭窄或闭塞及出血转化的患者比例均显著高于预后良好组(P<0.05)。预后不良组患者Lp-PLA2、Cys C水平高于预后良好组(P<0.05)。小穿通支梗死、后循环梗死、前-后循环梗死、MCA狭窄或闭塞、ICA和MCA均狭窄或闭塞、出血转化、血清Lp-PLA2及Cys C对患者发生短期预后不良均具有一定预测价值(P<0.05)。结论ACI患者的MRI表现(缺血半暗带、HV阳性、不同类型的脑梗死及血管狭窄情况)以及血清Lp-PLA2和Cys C水平可以预测其短期预后,为临床治疗方案的制定提供重要的参考依据。

Objective To explore the magnetic resonance imaging(MRI)manifestations of acute cerebral infarction(ACI)and the correlation between lipoprotein-associated phospholipase A2(Lp-PLA2),cystatin C(Cys C)and short-term prognosis.Methods A total of 110 ACI patients admitted to the department of neurology in our hospital from January 1,2022 to January 1,2023 were selected as the study objects.The clinical data and multimodal MRI were collected,and the serum Lp-PLA2 and Cys C levels of patients were detected.The patients were divided into the good prognosis group and the poor prognosis group according to the modified Rankin scale(mRS)score 90 days after onset.The predictive value of MRI manifestations and Lp-PLA2 and Cys C levels for short-term poor prognosis was analyzed.Results There were statistically significant differences in the time from onset to admission,National Institute of Health Stroke Scale(NIHSS)score on admission,hypertension or diabetes,coronary heart disease or atrial fibrillation of patients between the good prognosis group and the poor prognosis group(P<0.05).The proportions of patients with ischemic penumbra,HV positive,cortical-subcortical infarction,large perforating branch infarction,small perforating branch infarction,bilateral anterior circulation infarction,posterior circulation infarction,anterior-posterior circulation infarction,middle cerebral artery(MCA)stenosis or occlusion,both internal carotid artery(ICA)and MCA stenosis or occlusion,posterior cerebral artery(PCA)or vertebral artery(VA)stenosis or occlusion and hemorrhage transformation in the poor prognosis group were significantly higher than those in the good prognosis group(P<0.05).The Lp-PLA2 and Cys C levels of patients in the poor prognosis group were significantly higher than those in the good prognosis group(P<0.05).Small penetrating branch infarction,posterior circulation infarction,anterior-posterior circulation infarction,MCA stenosis or occlusion,both ICA and MCA stenosis or occlusion,hemorrhage transformation,serum Lp-PLA2 and Cys C had certain predictive value for patients with short-term poor prognosis(P<0.05).Conclusion MRI manifestations(ischemic penumbra,HV positivity,different types of cerebral infarction,and vascular stenosis)and serum Lp-PLA2 and Cys C levels can predict the short-term prognosis of ACI patients and provide important reference for the formulation of clinical treatment plans.
