Abstract

Abstract:

Objective To analyze the risk factors of progressive motor dysfunction (PMD) in patients with cerebral infarction due to perforating artery disease (PAD). Methods Patients with PAD cerebral infarction diagnosed by MRI were divided into PMD group and non-PMD Group. The demographic data, vascular risk factors, lesions characteristics, laboratory test result, prognosis and stroke recurrence at 3 and 6 months were compared between the two groups. Multivariate analysis was used to determine the independent risk factors for PMD. Results A total of 287 patients with PAD were enrolled in this study, including 95 patients with PMD and 192 patients with non-PMD. The males (P =0.03), smoking (P =0.04), the glycated hemoglobin (P <0.001), homocysteine (P =0.02), D-dimer (P =0.01) and infarct diameter (P <0.001) were all significantly higher in PMD group than that in non-PMD Group. There was no significant difference in the NIHSS scores at admission between the two groups, but the NIHSS scores at discharge in PMD group was higher than that in non-PMD group (7.69±1.87 vs 2.13±0.49, P <0.001). The rate of good prognosis at 3 months in PMD group was lower than that in non-PMD Group (55.7% vs 70.8%, P =0.01), while the two groups had no statistical difference at 6 months. There were no significant difference in recurrent cerebral infarction at 3 and 6 months between the two groups. Multivariate analysis showed that high glycated hemoglobin level (OR 1.083, 95%CI 1.062-1.105, P =0.03) and large infarct diameter (OR 1.051, 95%CI 1.030-1.073, P =0.01) were independent risk factors for PMD. Conclusions Of patients with cerebral infarction due to PAD, the patients occurring PMD had more severe neurological function deficit and worse prognosis at 3 months. Glycated hemoglobin and infarct diameter can be used as predictors for PMD.

摘要：

目的分析穿支动脉疾病（penetrating artery disease，PAD）型脑梗死出现进展性运动障碍（progressive motor deficits，PMD）的相关危险因素及患者预后。方法连续入组经头颅MRI确诊的PAD型脑梗死病例，按是否出现PMD分为PMD组与非PMD组例，比较两组的人口学资料、血管危险因素、病灶特点、实验室指标、3个月和6个月预后良好（mRS评分 0～2分）率及脑梗死复发情况。进一步对PMD的可能影响因素进行多因素分析，判断其独立危险因素。结果研究共入组287例PAD型脑梗死患者，其中PMD组95例，非PMD组192例。与非PMD组相比， PMD组男性患者（P =0.03）、吸烟（P =0.04）、糖化血红蛋白（P <0.001）、Hcy（P =0.02）和D-二聚体（P =0.01）水平较高，脑梗死灶直径较大（P <0.001）。两组患者入院时NIHSS评分差异无统计学意义，但出院时PMD组NIHSS评分高于非PMD组（7.69±1.87分 vs 2.13±0.49分，P <0.001）；3个月随访PMD组预后良好率较低（55.7% vs 70.8%，P =0.01），6个月随访两组预后无显著差异；两组3个月及6个月脑梗死复发率差异无统计学意义。多因素分析显示高糖化血红蛋白水平（OR 1.083，95%CI 1.062～1.105， P =0.03）和较大的脑梗死灶直径（OR 1.051，95%CI 1.030～1.073，P =0.01）是PMD的独立危险因素。结论 PAD型脑梗死患者中，出现PMD者早期神经功能缺损较重，3个月预后较差。糖化血红蛋白水平及脑梗死灶直径可作为PAD型脑梗死患者PMD的预测指标。

者的神经功能预后一般较好[29]。本研究发现

PMD患者3个月及6个月复发率相对较高，早

期（发病3个月）神经功能损害虽较重，但远

期（发病6个月）预后较好，与未出现病情进展

的患者预后相似。国内的氯吡格雷用于急性非

致残性缺血性脑血管病事件高危人群的疗效

（Clopidogrel in High-risk Patients With

Event s，CHANCE）研究显示，早期联合使

用氯吡格雷和阿司匹林21 d可减少轻型卒中

（NIHSS评分≤3分）患者90 d内卒中复发率[30]。

而PAD型脑梗死多数症状相对较轻，属于轻

型卒中，因此CHANCE研究的结果也为PAD型

脑梗死的临床治疗和研究提供了新的思路。

虽然通过常规手段检出穿支动脉的狭窄

及硬化存在一定困难，但目前高分辨率磁共振

成像（high resolution magnetic resonance

imaging，HR-MRI）的应用使检测PAD有了可

能。HR-MRI虽然不能直接判定穿支动脉的狭

窄情况，但可以检测出穿支动脉上游载体动脉

的病变，因此可间接反映穿支动脉病变[31]。本

研究未进行HR-MRI检查以了解此类患者更详

细的病变影像学特点，随着技术的进步，针对

PAD及其所致脑梗死的后续研究中，会利用更

先进的影像学技术来进行此类患者影像学标志、

影像学与临床特点和预后关系的研究。另外，

本研究为单中心，相对样本量较小的研究，也可

能会造成一定的结果偏移，在后续研究中也会

相应调整，进行更长期、更大样本量的研究。
