高同型半胱氨酸型高血压与急性脑梗死的相关性分析

目的探讨高同型半胱氨酸型高血压（H型高血压）与急性脑梗死的相关性。方法连续纳入经头部MRI确诊的急性脑梗死患者220例。将同期入院的120例短暂性脑缺血发作（TIA）患者作为对照组。记录患者的年龄、高血压、糖尿病、高脂血症和家族史等危险因素。于发病第2、3天空腹抽取所有受试者的静脉血,采用高效液相色谱法测定血清同型半胱氨酸（Hcy）水平。以Hcy≥10μmol/L作为高同型半胱氨酸血症（HHcy）的标准,高血压伴HHcy者为H型高血压。仅Hcy升高者为单纯HHcy组,仅血压升高者为单纯高血压组。结果①脑梗死组患者Hcy水平高于TIA组（19.7±8.3）μmol/L比（13.3±3.5）μmol/L;]高血压、HHcy、H型高血压的发生率高于TIA组,差异均有统计学意义,均P〈0.01。②340例患者中,高血压患者的脑梗死发生率高于血压正常者（70.0%比51.6%;χ2=10.290,P〈0.01）;HHcy患者的脑梗死发生率高于Hcy正常者（70.2%比31.3%;χ2=27.396,P〈0.01）。H型高血压组的脑梗死发生率（73.3%）高于单纯高血压组（42.3%）、单纯HHcy（61.3%）及血压和Hcy均正常组（18.2%）,差异均有统计学意义（P〈0.01,P〈0.05）。③多因素Logistic回归显示,急性脑梗死的独立危险因素为H型高血压（OR=3.34,95%CI：1.59～7.02）和HHcy（OR=1.969,5%CI：1.15～3.36）。结论急性脑梗死患者Hcy水平高于TIA组的患者。H型高血压脑梗死的发生率较高,H型高血压可能是导致卒中事件的独立危险因素。

Correlative analysis of H-type hypertension and acute cerebral infarction

Objective To investigate the correlation between H-type hypertension and acute cerebral infarction.Methods A total of 220 consecutive patients with acute cerebral infarction diagnosed by head MRI were included in the study.At the same period,120 hospitalized patients with transient ischemic attack(TIA) whose cerebral infarction were excluded with head MRI were used as the control group.The age,hypertension,diabetes,hyperlipidemia,family history and other risk factors of the patients were documented.The fast...
