【摘要】:短暫性腦缺血發(fā)作(Transient ischemic attack,TIA)是缺血性腦卒中的早期預警信號,臨床上分為前循環(huán)(頸內(nèi)動脈系統(tǒng))TIA及后循環(huán)(椎基底動脈系統(tǒng))TIA。ABCD3評分是目前對TIA進行相關(guān)風險評估應用較為廣泛的一種量化指標,但ABCD3評分并不能預測出所有的腦卒中患者。血漿低密度脂蛋白膽固醇(Low Density Lipoprotein Cholesterol, LDL-C)水平是動脈粥樣硬化(Atherosclerosis,AS)的一個主要危險因素。本研究主要探討ABCD3評分聯(lián)合LDL-C水平評估TIA后卒中風險是否優(yōu)于單純應用ABCD3評分,旨在為基層醫(yī)院找到一種經(jīng)濟實惠、便捷有效的客觀指標,對TIA臨床治療提供依據(jù)。 目的 探討ABCD3評分聯(lián)合LDL-C水平對TIA后卒中風險的預測價值,并與ABCD3評分進行比較,旨在為基層醫(yī)院提供一種便捷有效的評估TIA后早期卒中風險的方法,便于制定個體化的二級預防策略。 方法 以2010年9月至2013年9月在三門峽市中心醫(yī)院神經(jīng)內(nèi)科住院治療的TIA患者268例為研究對象,前瞻性收集其所有臨床資料。所有入選患者均符合WHO的TIA定義,亦經(jīng)過影像學(頭顱MRI+DWI,頸部血管B超,頭頸聯(lián)合MRA,頭頸聯(lián)合CTA,DSA等)檢查,觀察TIA后第2天,第7天是否發(fā)生卒中。所有患者均進行ABCD3評分,并進行風險分層,低危組(0-3分),中危組(4-6分),高危組(≥7分),并于住院第二日清晨抽取靜脈血測定其血漿LDL-C水平。用ABCD3評分法和ABCD3+LDL-C評分法分別測定268例TIA患者的評分,并觀察TIA后2天及7天內(nèi)腦梗死的發(fā)生率,并計算各自ROC曲線下面積,比較2種方法對TIA后早期腦梗死預測能力。應用卡方檢驗針對ABCD3L評分法各危險分層間的2天、7天腦梗死發(fā)生率進行比較,判斷各危險分層間腦梗死發(fā)生的差異,指導臨床治療,P<0.05有統(tǒng)計學意義。 結(jié)果 納入TIA患者268例,其中男性159例(59.3%),女性109例(40.7%),,患者年齡29-82歲,平均年齡(61.13±15.67)歲。2天內(nèi)腦梗死19例(7.1%),7天內(nèi)腦梗死28例(10.4%)。隨著評分的增加,缺血性腦卒中風險增加。2天、7天的ABCD3評分系統(tǒng)AUROC分別為0.785(95%CI=0.675-0.892,P0.001)、0.832(95%CI=0.751-0.913,P0.001);ABCD3L評分系統(tǒng)AUROC分別為0.852(95%CI=0.762-0.943,P0.001)、0.879(95%CI=0.811-0.956,P0.001);兩者均以ABCD3L評分系統(tǒng)曲線下面積最大(P<0.001)。按ABCD3L評分分級,高危組(7-10分)、中危組(4-6分)、低危組(0-3分)2天內(nèi)腦梗死風險分別為20.2%、1.6%、0%(P<0.001);7天內(nèi)腦梗死風險分別為27.4%、3.9%、0%(P<0.001)。ABCD3L評分為7-10分的TIA患者2天、7天梗死率分別為評分0-6分患者的12倍、7倍。 結(jié)論 將ABCD3評分與血漿LDL-C水平相結(jié)合可以更好地評估TIA患者發(fā)作后早期卒中風險。
[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
