【摘要】:目的:探討影響急性腦梗死患者血壓變異性的因素及血壓變異性是否與急性腦梗死發(fā)病3個月末、6個月末的預后有關。方法:前瞻性登記2012年1月1日到2012年9月31日因急性缺血性腦卒中連續(xù)入四川省人民醫(yī)院神經(jīng)內(nèi)科的患者。詳細登記患者的基本情況,收集患者可能影響血壓變異性(blood pressure variability,BPV)及預后的相關病史和生活史。根據(jù)我院的動態(tài)血壓機型和參考國內(nèi)外文獻,選擇24小時收縮壓標準差(24hours systemic blood pressurestandard deviation,24hSBP SD),24小時舒張壓標準差(24hoursdiastolic blood pressure standard deviation,24hDBP SD)代表BPV,研究影響急性腦梗死患者BPV的因素。隨訪發(fā)病3個月末和6個月末的結(jié)局,研究BPV與預后的關系。采用改良Rankin量表評分(Modified Rankin Scale,MRS)評估預后,MRS≤2分為非殘疾,MRS3-5分為殘疾[1],MRS=6分為死亡,主要采用電話隨訪及門診隨訪。統(tǒng)計方法:計量資料采用均數(shù)±標準差(x±s)或中位數(shù)描述。兩組計量資料比較,若數(shù)據(jù)服從正態(tài)分布,采用t檢驗;若非正態(tài)分布,采用秩和檢驗。計數(shù)資料采用百分比描述。兩組計數(shù)資料比較,采用卡方檢驗。1.對各危險因素進行單因素分析,P<0.05的自變量[2],進入Binary Logistic回歸分析,明確急性腦梗死患者BPV的獨立影響因素。2.對有可能影響預后的風險因素進行單因素分析,P0.05的進入Binary Logistic回歸分析,明確預后的獨立影響因素,探討B(tài)PV對腦梗死預后有無影響。結(jié)果:本研究納入254例研究對象,包括男性175(68.8%)例,女性79(31.1%)例,年齡范圍30-98歲,,平均年齡66.93±10.43歲,住院期間死亡22例(8.66%),3個月末死亡26例(10.24%),6個月末死亡29例(11.4%),3個月末死亡/殘疾91例(35.82%),6個月末死亡/殘疾79例(31.1%)。通過多因素分析發(fā)現(xiàn)1.高血壓(OR3.207,95%CI1.739-5.914)、糖尿病(OR2.074,95%CI1.103-3.899)、男性(OR2.778,95%CI1.429-5.339)、年齡(OR1.069,95%CI1.033-1.107)是24hSBP SD的獨立影響因素。2.高血壓(OR2.048,95%CI1.198-3.501)、吸煙(OR1.845,95%CI1.002-3.396)、男性(OR1.819,95%CI1.007-3.286)是影響24hDBP SD的獨立影響因素。3.入院時NIHSS評分是患者在住院期間,3個月末和6個月末死亡的獨立影響因素,OR值和95%可信區(qū)間分別是(OR2.01,95%CI1.416-2.853),(OR1.467,95%CI1.255-1.713),(OR1.345,95%CI1.212-1.491)。4.24hDBP SD(OR1.268,95%CI1.03-1.562)、糖尿。∣R2.434,95%CI1.201-4.933)、NIHSS(OR1.207,95%CI1.143-1.275)是影響3個月末預后的獨立影響因素。5.24hDBP SD(OR1.232,95%CI1.000-1.518)、糖尿。∣R2.17,95%CI1.043-4.516)、NIHSS(OR1.122,95%CI1.155-1.292)是影響6個月末預后的獨立影響因素。結(jié)論:1.急性腦梗死患者的BPV水平受高血壓、糖尿病、性別、吸煙、年齡影響,控制好血壓、血糖及戒煙可以降低異常血壓變異性,改善患者預后。2.24hDBP SD可以成為判斷急性腦梗死患者預后的一項指標,24hDBP SD越大,患者出現(xiàn)不良結(jié)局(殘疾或死亡)的可能性越大。
[Abstract]:Objective: to investigate the factors affecting blood pressure variability in patients with acute cerebral infarction and whether blood pressure variability is related to the prognosis of acute cerebral infarction at the end of 3 months and 6 months. Methods: from January 1, 2012 to September 31, 2012, patients with acute ischemic stroke were enrolled in the Department of Neurology, Sichuan people's Hospital. The basic situation of the patients was registered in detail, and the related medical history and life history of the patients who might affect the blood pressure variability (blood pressure variability,BPV) and prognosis were collected. According to the ambulatory blood pressure model of our hospital and reference to the literature at home and abroad, the 24-hour systolic blood pressure standard deviation (24hours systemic blood pressurestandard deviation,24hSBP SD), 24-hour diastolic blood pressure standard deviation (24hoursdiastolic blood pressurestandard deviation,24hDBP SD) is selected to represent BPV,. To study the factors affecting BPV in patients with acute cerebral infarction. The outcomes at the end of 3 months and 6 months were followed up to study the relationship between BPV and prognosis. The prognosis was evaluated by modified Rankin scale score (Modified Rankin Scale,MRS). MRS 鈮
