【摘要】:短暂性脑缺血发作(Transient ischemic attack,TIA)是缺血性脑卒中的早期预警信号,临床上分为前循环(颈内动脉系统)TIA及后循环(椎基底动脉系统)TIA。ABCD3评分是目前对TIA进行相关风险评估应用较为广泛的一种量化指标,但ABCD3评分并不能预测出所有的脑卒中患者。血浆低密度脂蛋白胆固醇(Low Density Lipoprotein Cholesterol, LDL-C)水平是动脉粥样硬化(Atherosclerosis,AS)的一个主要危险因素。本研究主要探讨ABCD3评分联合LDL-C水平评估TIA后卒中风险是否优于单纯应用ABCD3评分,旨在为基层医院找到一种经济实惠、便捷有效的客观指标,对TIA临床治疗提供依据。 目的 探讨ABCD3评分联合LDL-C水平对TIA后卒中风险的预测价值,并与ABCD3评分进行比较,旨在为基层医院提供一种便捷有效的评估TIA后早期卒中风险的方法,便于制定个体化的二级预防策略。 方法 以2010年9月至2013年9月在三门峡市中心医院神经内科住院治疗的TIA患者268例为研究对象,前瞻性收集其所有临床资料。所有入选患者均符合WHO的TIA定义,亦经过影像学(头颅MRI+DWI,颈部血管B超,头颈联合MRA,头颈联合CTA,DSA等)检查,观察TIA后第2天,第7天是否发生卒中。所有患者均进行ABCD3评分,并进行风险分层,低危组(0-3分),中危组(4-6分),高危组(≥7分),并于住院第二日清晨抽取静脉血测定其血浆LDL-C水平。用ABCD3评分法和ABCD3+LDL-C评分法分别测定268例TIA患者的评分,并观察TIA后2天及7天内脑梗死的发生率,并计算各自ROC曲线下面积,比较2种方法对TIA后早期脑梗死预测能力。应用卡方检验针对ABCD3L评分法各危险分层间的2天、7天脑梗死发生率进行比较,判断各危险分层间脑梗死发生的差异,指导临床治疗,P<0.05有统计学意义。 结果 纳入TIA患者268例,其中男性159例(59.3%),女性109例(40.7%),,患者年龄29-82岁,平均年龄(61.13±15.67)岁。2天内脑梗死19例(7.1%),7天内脑梗死28例(10.4%)。随着评分的增加,缺血性脑卒中风险增加。2天、7天的ABCD3评分系统AUROC分别为0.785(95%CI=0.675-0.892,P0.001)、0.832(95%CI=0.751-0.913,P0.001);ABCD3L评分系统AUROC分别为0.852(95%CI=0.762-0.943,P0.001)、0.879(95%CI=0.811-0.956,P0.001);两者均以ABCD3L评分系统曲线下面积最大(P<0.001)。按ABCD3L评分分级,高危组(7-10分)、中危组(4-6分)、低危组(0-3分)2天内脑梗死风险分别为20.2%、1.6%、0%(P<0.001);7天内脑梗死风险分别为27.4%、3.9%、0%(P<0.001)。ABCD3L评分为7-10分的TIA患者2天、7天梗死率分别为评分0-6分患者的12倍、7倍。 结论 将ABCD3评分与血浆LDL-C水平相结合可以更好地评估TIA患者发作后早期卒中风险。
[Abstract]:Transient ischemic attackTIA is an early warning signal for ischemic stroke. Clinical classification into anterior circulation (internal carotid artery system TIA and posterior circulation) (vertebrobasilar artery system TIA. ABCD3 score is currently used to assess the risk of TIA is a relatively wide range of quantitative indicators, but ABCD3 score can not predict all stroke patients. Plasma low density lipoprotein cholesterol low density lipoprotein Cholesteroll (LDL-C) is a major risk factor for atherosclerosis. The purpose of this study was to explore whether ABCD3 score combined with LDL-C in assessing stroke risk after TIA is superior to ABCD3 score alone in order to find an economical, convenient and effective objective index for basic hospitals and to provide evidence for clinical treatment of TIA. Objective to explore the predictive value of ABCD3 score combined with LDL-C in predicting the risk of post-TIA stroke and compare it with ABCD3 score in order to provide a convenient and effective method for assessing the risk of early post-TIA stroke in primary hospitals. Facilitate the formulation of individualized secondary prevention strategies. Methods from September 2010 to September 2013, 268 patients with TIA who were hospitalized in Department of Neurology, Sanmenxia Central Hospital, were studied and all clinical data were collected prospectively. All the patients were in accordance with WHO definition of TIA, and underwent imaging examination (head MRI DWI, cervical vascular B ultrasound, head and neck combined MRAs, head and neck combined with CTA DSA, etc.) to observe whether stroke occurred on the 2nd and 7th day after TIA. All patients were assessed with ABCD3 score and risk stratification. The low risk group was 0-3 minutes, the middle risk group was 4-6 minutes, the high risk group (鈮
