目的

探讨血浆D-二聚体(D-D)和血清氧化低密度脂蛋白(ox-LDL)与急性脑梗死(ACI)患者急性卒中Org 10172治疗试验(trial of org 10172 in acute stroke treatment,TOAST)分型、疾病严重程度及短期预后的关系。

方法

选取2021年10月至2024年10月铜川矿务局中心医院收治的146例ACI患者作为研究对象,其中男性86例,女性60例;年龄25~76岁[(52.94±7.45)岁]。根据TOAST分型分为大动脉粥样硬化型(LAA)、心源性栓塞型(CE)、小动脉闭塞型(SAO)、其他明确病因型(SOE)和不明原因型(SUE)5型,比较不同TOAST分型患者血浆D-D和血清ox-LDL水平的差异。依据美国国立卫生研究院卒中量表(NIHSS)对患者疾病严重程度进行评估,分为轻度组(51例)、中度组(67例)及重度组(28例)。采用改良RANKIN量表(mRS)对患者治疗3个月后的预后情况进行评分,根据分值的高低对患者进行预后分组。以Spearman分析血浆D-D、血清ox-LDL与ACI患者疾病严重程度、短期预后的相关性。

结果

CE型患者血浆D-D水平最高,其次为LAA型,SAO型最低(P<0.05),SAO与SUE型患者血浆D-D水平比较差异无统计学意义(P>0.05);LAA型患者血清ox-LDL水平最高,其次为SAO型,CE型次之,SUE型最低(P<0.05)。D-D、ox-LDL水平随疾病严重程度的增加而升高,D-D、ox-LDL水平与疾病严重程度均呈正相关(r=0.713、0.679,P<0.05)。D-D、ox-LDL水平随患者短期预后评分的增加而升高,D-D、ox-LDL水平与短期预后评分均呈正相关(r=0.802、0.749,P<0.05)。

结论

不同TOAST分型患者的血浆D-D、血清ox-LDL水平具有差异性,且血浆D-D、血清ox-LDL水平与ACI疾病严重程度、短期预后均有相关性。

Objective

To investigate the correlation of plasma D-dimer (D-D) and serum oxidized low-density lipoprotein (ox-LDL) with the Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification, disease severity and short-term prognosis in patients with acute cerebral infarction (ACI).

Methods

A total of 146 patients with ACI admitted to Tongchuan Mining Bureau Central Hospital from October 2021 to October 2024 were enrolled, including 86 males and 60 females, aged 25~76 years [(52.94±7.45) years]. According to the TOAST clssification, patients were divided into five subtypes: large-artery atherosclerosis (LAA), cardioembolism (CE), small-artery occlusion (SAO), stoke of other determined etiology (SOE), and stoke of undetermined etiology (SUE). Plasma D-D and serum ox-LDL levels were compared among different TOAST subtypes. Disease severity was assessed using the National Institutes of Health Stroke Scale (NIHSS), and patients were divided into mild (n=51), moderate (n=67), and severe (n=28) groups. The modified Rankin Scale (mRS) was used to evaluate prognosis at 3 months after treatment, and patients were grouped according to their mRS scores. Spearman correlation analysis was performed to analyze the correlations of plasma D-D and serum ox-LDL with disease severity and short-term prognosis in ACI patients.

Results

Plasma D-D level was the highest in the CE subtype, followed by LAA subtype, and the lowest in SAO subtype (P<0.05). No significant difference in D-D level was found between SAO and SUE subtypes patients (P>0.05). Serum ox-LDL level was the highest in LAA subtype, followed by the SAO subtype, then the CE subtype, and the lowest in SUE subtype (P<0.05). Plasma D-D and serum ox-LDL levels increased with the severity of the disease, and both were positively correlated with NIHSS scores (r=0.713 and 0.679, both P<0.05). D-D and ox-LDL levels increased with higher mRS scores, and both were positively correlated with short-term prognosis scores (r=0.802 and 0.749, both P<0.05).

Conclusion

Plasma D-D and serum ox-LDL levels differ among patients with different TOAST subtypes, and both are correlated with disease severity and short-term prognosis in ACI patients..
