摘要
报道了高血压脑梗塞患者190例,其中老年人134例,占70.5％。研究表明患者过去最高血压(平均动脉压18.0l±2.62kPa)与脑梗塞数目(2.47±1.18)和面积(1.37±0.89cm)之间呈显著正相关(分别γ=0.4180,γ=0.4086;p<0.01)。而入院时血压水平(平均动脉压15.02±2.10kpa)与其梗塞面呈显著负相关(γ=-0.2398,P<O.01),60～69岁组、>70岁组与<60岁组,其梗塞数目与面积相关也显著(γ=0.3524,γ=0.3662,γ=0.3295;p<0.01)。梗塞以基底节区和侧脑部位最多,分别为43.41％(201/463个);23.33％(108/463个),均较其余两组有显著差别,(t=3.29,t=2.28;P<0.01)。脑腔隙性梗塞26.84％(51/190例),非腔隙型71.16％(139/190例);有症状者较无症状者多见。结果表明:过去最高血压与脑梗塞部位和范围关系密切,入院时血压水平可能是诱发脑梗塞的直接原因之一,各组梗塞数目与面积趋向一致;基底节区、侧脑是老年高血压性脑梗塞多发部位。
We studied 190 patients with hypertensive cerebral infarcts ,among them 134 senile cases(70.5%). The results showed that there were motable differences in the mean arterial pressure (MAP) among three groups. The patient's highest MAP(18.01±2.62 kPa) in the past was quite closely related to the numbers (2.47 ±1.18) and the size (1.37 + 0.89 cm) of the infarct loci(γ 0.4180 ,γ 0.4086 respectively;P<0. 01) ,while MAPU5.02±2.10kPa)of patients on admission seemed to be negative relation to the size of infarcts in all patients (γ= - 0. 2398 ,P<0. 01). In the 3 senile groups ,there were also remarked correlations between BP and the numbers and size of the infarcts (γ=0. 3524 , γ=0. 3662 , γ= 0. 3295 ;P>0. 01). Most of infarct loci appeared in the basal ganglia and the lateral brain (43. 41% , 201/463; 23. 33% ,108/463). In addition , lacunar and non-lacunar cerebral infarctions are 26. 84%(51/190 cases) ,71. 16%(139/190 cases) ,respectively ,the symptomatic are more common than the asymptomatic. Hence , it seems to reveal that the close relation between the highest MAP of patients before admission and the infarct loci and sizes. The levelof blood presssure on admission might be one of the direct causes to induce the infarct. The basal ganglia and the lateral brain are the loci where most of infarcts occur in senile patients.
