入院时血压对急性心肌梗死患者的影响

The influence of admission blood pressure on patients of acute myocardial infarction

目的探讨入院时血压对急性心肌梗死(AMI)患者的影响。方法将442例AMI患者按入院时血压高低分为3组:A组283例血压正常,<140/90 mmHg;B组86例为高血压1级,血压≥140～159/90～99 mmHg;C组73例为高血压2～3级,血压≥160/100 mmHg。并分析3组临床特点。结果①方差分析和多组间比较显示,3组在心率、胆固醇(TC)、载脂蛋白B(apo B)、前壁梗死、多壁梗死、心梗复发、高血压病史的差别有显著性意义(P<0.05～P<0.01)。②与A组比较,B组心率、TC、低密度脂蛋白胆固醇(LDL-C)、前壁梗死、高血压病史高,多壁梗死比例低;C组TCa、po B、心梗复发高,多壁梗死和再通低,差别有显著性意义(P<0.05～P<0.01)。③与B组比较,C组心率低,差别有显著性意义(P<0.05)。结论入院时血压高的AMI患者血脂紊乱明显,高血压病史、前壁梗死和心梗复发比例高,多壁梗死和再通比例低。

Objective To investigate the influence of admission blood pressure on patients of acute myocardial infarction（AMI）.Methods The study was performed in 442 patients who suffered from AMI.According to admission blood pressure,these patients were divided into three groups.A group1（n=283） was without hypertension（140/90 mmHg）.B group（n=86） was hypertension 1 grade（140~159/90~99 mmHg）.C group（n=73） was hypertension 2~3 grade（≥160/100 mmHg）.The clinic characteristics were analzed.Results One way analysis of variance and group comparison shown that there was significant difference in heart rate,cholesterol（TC）,apolipoprotein B（apo B）,anterior infarcts,multi-wall infarcts,infarcts recurrence,and hypertension history among three groupv（P 0.05~P0.01）.Compared with A group,heart rate,TC,LDL-C,anterior infarctus,and hypertension history was increased,and multi-wall infarcts was decreased in B group;TC,apo B and infarcts recurrence was increased,multi-wall infarcts and recanalization was decreased in C group（P0.05~P0.01）.Compared with B group,heart rate was decreased in C group（P0.05）.Conclusion AMI patients with admission hypertension have more blood lipid disorder,hypertension history,anterior infarcts,and infarctus recurrence,have less multi-wall infarctus and recanalization.
