血压变异性与急性脑梗死牛津郡社区卒中项目分型的关系

目的探讨血压变异性（blood pressure variability，BPV）与急性脑梗死牛津郡社区卒中项目（OCSP）分型的关系。方法选择2011年9月．2012年8月唐山市协和医院的急性脑梗死患者236例．按OCSP分割分为完全前循环梗死（TACI）组26例、部分前循环梗死（PACI）组76例、后循环梗死（POCI）组42例和腔隙性梗死（LACI）组92例进行动态血压监测，观察各组血压昼夜节律．结果①TACI组、POCI组日间收缩压标准筹（dSSD）（13．17±1．63）、（13．40±1．29）mmHg]、舒张压标准差（dDSD）（8．76±1．41）、（8．98±1．48）mmHg]、夜间收缩压标准差（nSSD）I（11．68±1．65）、（I1．85±1．00）mmHg]高于LACI组（12．03±1．91）、（7．94±1．55）、（10．52±1．51）mmHg]，差肄仃统计学意义（P〈0．05）；舒张压标准差（nDSD）组间筹异无统计学意义（P〉0．05）。②各组亚型之间收缩胝、舒张爪懵使肖律比例差异有统计学意义（P〈0．05）。进行分割X^2检验，TACI组、POCI组收缩压杓型’仃律栉比例1192％（5／26）、23．8％（10／42）1均低于LACI组44．6％（41／92）]差异有统计学意义（X^2=9．33、8．57，P〈0．05）；TACI组、POCI细舒张乐杓型节律者比例119．2％（5／26）、21．4％（9／42）1低于LACI组42．4％（39／92）]差异均有统计学意义（X^2=9．71、9．66，P〈0．05）结论血压变异性与急性腑梗死OCSP分型中TACI、POCI、IE型行天。

Relationship between blood pressure variability and the OCSP typing of acute cerebral infarction

Objective rFo analyze the relationship between blood pressure variability and the Oxforshire Community Stroke Project （OCSP） typing of acute cerebral infarction. Methods 236 patients with acute cerebral infarction from September 2011 to Augusl 2012 in Xiehe Hospital of Tangshan City were selected and classified into total anterior eirculation infarct （TACI, n = 26）, partial anterior circulation infaretion （PACI, n = 76）, posterior circulation inlarction （POCI, n = 42） and Lacunar cerebral infarction （LACI, n = 92） according to OCSP criteria, Dynamic blood pressure was monitored; circadian rhythm of blood pressure was observed. Results ①dSSD, dDSD, nSSD in TACI group （ 13.17± 1.63）, （8.76± 1.41 ）, （1 1.68± 1.65）mmHg] and POCI group （13.40± 1.29）, （8.98± 1.48）, （11.85± 1.00）ram Hg] were higher than those in I,ACI group （12.03±1.91）, （7.94±1.55）, （10.52±1.51） mm Hg], the differences were statistically significant （P 〈 0.05）： the difference of nDSD in the 4 groups was not statistically significant （P 〉 0.05）. ②The differenee of circadian rhythm of systolic pressure and diastolic pressure in hypotypes of 4 groups was statistically significant （P 〈 0.05）. The ratio of dipper rhythm type of systolic pressure in TACI group and POCI group 19.2% （5/ 26）, 23.8%,4 （10/42）1 were lower than those in LACI group 44.6% （41/92）], the differences were statistieally significant （X^2 = 9.33, 8.57, P 〈 0.05）; the ratio of dipper rhythm type of diastolic pressre in TACI group and POCI group l19.2% （5/26）, 21.4% （9/42）] were lower than those in LACI group 42.4% （39/92）], he differences wen, statistically significant （X^2 = 9.71, 9.66, P 〈 0.05）. Conclusion Blood pressure variability has relationship with subtypes TACI and POCI of OCSP in acute cerebral infarction.
