发布时间:2019-06-11 14:28
【摘要】:目的:探讨影响急性脑梗死患者血压变异性的因素及血压变异性是否与急性脑梗死发病3个月末、6个月末的预后有关。方法:前瞻性登记2012年1月1日到2012年9月31日因急性缺血性脑卒中连续入四川省人民医院神经内科的患者。详细登记患者的基本情况,收集患者可能影响血压变异性(blood pressure variability,BPV)及预后的相关病史和生活史。根据我院的动态血压机型和参考国内外文献,选择24小时收缩压标准差(24hours systemic blood pressurestandard deviation,24hSBP SD),24小时舒张压标准差(24hoursdiastolic blood pressure standard deviation,24hDBP SD)代表BPV,研究影响急性脑梗死患者BPV的因素。随访发病3个月末和6个月末的结局,研究BPV与预后的关系。采用改良Rankin量表评分(Modified Rankin Scale,MRS)评估预后,MRS≤2分为非残疾,MRS3-5分为残疾[1],MRS=6分为死亡,主要采用电话随访及门诊随访。统计方法:计量资料采用均数±标准差(x±s)或中位数描述。两组计量资料比较,若数据服从正态分布,采用t检验;若非正态分布,采用秩和检验。计数资料采用百分比描述。两组计数资料比较,采用卡方检验。1.对各危险因素进行单因素分析,P<0.05的自变量[2],进入Binary Logistic回归分析,明确急性脑梗死患者BPV的独立影响因素。2.对有可能影响预后的风险因素进行单因素分析,P0.05的进入Binary Logistic回归分析,明确预后的独立影响因素,探讨BPV对脑梗死预后有无影响。结果:本研究纳入254例研究对象,包括男性175(68.8%)例,女性79(31.1%)例,年龄范围30-98岁,,平均年龄66.93±10.43岁,住院期间死亡22例(8.66%),3个月末死亡26例(10.24%),6个月末死亡29例(11.4%),3个月末死亡/残疾91例(35.82%),6个月末死亡/残疾79例(31.1%)。通过多因素分析发现1.高血压(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)、年龄(OR1.069,95%CI1.033-1.107)是24hSBP SD的独立影响因素。2.高血压(OR2.048,95%CI1.198-3.501)、吸烟(OR1.845,95%CI1.002-3.396)、男性(OR1.819,95%CI1.007-3.286)是影响24hDBP SD的独立影响因素。3.入院时NIHSS评分是患者在住院期间,3个月末和6个月末死亡的独立影响因素,OR值和95%可信区间分别是(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)、糖尿病(OR2.434,95%CI1.201-4.933)、NIHSS(OR1.207,95%CI1.143-1.275)是影响3个月末预后的独立影响因素。5.24hDBP SD(OR1.232,95%CI1.000-1.518)、糖尿病(OR2.17,95%CI1.043-4.516)、NIHSS(OR1.122,95%CI1.155-1.292)是影响6个月末预后的独立影响因素。结论:1.急性脑梗死患者的BPV水平受高血压、糖尿病、性别、吸烟、年龄影响,控制好血压、血糖及戒烟可以降低异常血压变异性,改善患者预后。2.24hDBP SD可以成为判断急性脑梗死患者预后的一项指标,24hDBP SD越大,患者出现不良结局(残疾或死亡)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
