【摘要】:目的:探討與非溶栓性急性腦梗死出血性轉(zhuǎn)化(hemorrhagic transformation,HT)相關(guān)的危險因素,并評估總膽固醇水平和低密度脂蛋白膽固醇水平對急性缺血性腦卒中出血性轉(zhuǎn)化的影響。 方法:回顧性分析2011年1月到2012年12月期間沈陽軍區(qū)總院神經(jīng)內(nèi)科確診為急性腦梗死住院治療的非溶栓患者240例,根據(jù)有無繼發(fā)出血分為出血性轉(zhuǎn)化組(HT組,41例)及非出血性轉(zhuǎn)化組(NHT組,199例);此外,根據(jù)國內(nèi)腦血管病患者血脂異常治療的目標(biāo)值(總膽固醇,TC<5.2mmol/L;低密度脂蛋白膽固醇,LDL-C<2.58mmol/L),把TC和LDL-C水平分別分成2組,即TC:1組<5.2mmol/l(134例),2組≥5.2mmol/l(106例);LDLC:1組<2.58mmol/l(103例),2組≥2.58mmol/l(127例)。對患者的一般資料:性別、年齡、高血壓病、糖尿病、吸煙、飲酒史及既往心房纖顫、冠心。òL(fēng)濕性心臟病、二尖瓣關(guān)閉不全);生化指標(biāo):入院時空腹血糖、血清總膽固醇、甘油三酯、低密度脂蛋白膽固醇、高密度脂蛋白膽固醇、脂蛋白a、梗死面積、尿蛋白定性等臨床資料進(jìn)行單因素分析,再對單因素中有統(tǒng)計學(xué)差異的因素采用非條件Logistic回歸分析,對總膽固醇和低密度脂蛋白膽固醇不同水平組與HT間的關(guān)系也分別用OR值的卡方檢驗進(jìn)行統(tǒng)計學(xué)分析比較。 結(jié)果:共納入240例急性缺血性腦卒中病例中,含有HT41例(血腫型11例,,非血腫型30例),NHT組199例,HT的發(fā)生率為17.1%;t檢驗中HT組總膽固醇水平、低密度脂蛋白(LDL-C)水平低于NHT組, HT組高密度脂蛋白水平高于NHT組,均有統(tǒng)計學(xué)意義(P<0.05)。OR值的卡方檢驗中,TC兩組比較x2=0.147,P=0.702>0.05;LDLC兩組比較x2=3.834,P=0.04960.05, OR=1.971,95%CI [0.991-3.918],兩組之間有統(tǒng)計學(xué)差異,說明是否發(fā)生出血性轉(zhuǎn)化與LDL-C的水平高低有關(guān),1組發(fā)生出血性轉(zhuǎn)化的危險度是2組的1.971倍,即LDL-C<2.58mmol/L組更易發(fā)生出血性轉(zhuǎn)化。此外,單因素分析中入院時空腹血糖、房顫、梗塞面積、收縮壓水平在HT和NHT兩組中存在明顯差異,具有顯著統(tǒng)計學(xué)意義(P<0.01)。多元回歸分析發(fā)現(xiàn)梗死面積(OR=0.086,95%CI0.033-0.221,P=0.000)、房顫(OR=4.038,95%CI1.502-10.857,P=0.006)、收縮壓水平(OR=1.023,95%CI1.012-2.355,P=0.011)、入院時空腹血糖(OR=0.791,95%CI0.664-0.941,P=0.008)、LDL-C (OR=2.984,95%CI1.462-6.091,P=0.003)。 結(jié)論:1. HT是在多因素相互作用下形成的一個復(fù)雜的病理過程,房顫、梗死面積、入院時空腹血糖水平、收縮壓水平及低密度脂蛋白膽固醇是HT發(fā)生的獨立危險因素。 2.隨著患者空腹血清低密度脂蛋白膽固醇水平的降低,HT發(fā)生的危險性增高,低水平低密度脂蛋白膽固醇可使出血性轉(zhuǎn)化發(fā)生的風(fēng)險升高。
[Abstract]:Objective: to investigate the risk factors associated with hemorrhagic transformation (hemorrhagic transformation,HT) of non-thrombolytic acute cerebral infarction and to evaluate the effects of total cholesterol and low density lipoprotein cholesterol on hemorrhagic transformation in acute ischemic stroke. Methods: from January 2011 to December 2012, 240 non-thrombolytic patients with acute cerebral infarction diagnosed by Department of Neurology, Shenyang military region General Hospital, were retrospectively analyzed. The patients were divided into hemorrhagic conversion group (HT group, 41 cases) and non-hemorrhagic transformation group (NHT group, 199cases), in addition, according to the target value (total cholesterol, TC < 5.2 mmol / L) of the patients with cerebrovascular disease, the patients with cerebral vascular disease were divided into hemorrhagic conversion group (HT group, 41 cases) and non-hemorrhagic transformation group (NHT group, 199 cases). Low density lipoprotein cholesterol (LDL-C < 2.58mmol/L), TC and LDL-C were divided into two groups: TC:1 group < 5.2mmol/l group (134 cases), LDLC:1 group < 2.58mmol/l group (103 cases) and LDLC:1 group 鈮
