[摘要] 意图 评论血清超敏C反响蛋白(hs-CRP)水平与冠状动脉慢血流现象(SCF)的相关性。 办法 挑选冠状动脉造影查看提示SCF的患者31例为SCF组以及冠状动脉造影查看示冠状动脉无狭隘且血流正常者36例为对照组,比较两组的血清hs-CRP水平,并以计算学处理剖析hs-CRP与SCF的联系。 成果 SCF组的血清hs-CRP水平显着高于对照组(P<0.05),且与均匀TIMI血流帧数呈正相关(r=0.476,P<0.01)。 定论 hs-CRP与SCF的构成进程密切相关。

冠状动脉慢血流现象(slow coronary flow,SCF)是指在外溶栓医治后、冠状动脉成形术后、冠状动脉扩张、冠状动脉痉挛、心肌病、瓣膜病等要素,惯例行冠状动脉造影查看后未发现冠状动脉显着病变,却呈现冠状动脉灌注推迟的现象。SCF临床表现为高血压、心绞痛、心肌梗死乃至猝死等[1-2]。这一现象由Tambe等于1972年初次提出。Rifai等[3]报导称有7%置疑有冠心病的患者进行冠状动脉造影有SCF发作。本研讨经过测定血清hs-CRP水平拟发现其与SCF发病的联系,然后能有用避免SCF的发作。

1 材料与办法

1.1 一般材料

选取冠状动脉造影查看示SCF的患者31例为SCF组,其间男18例,女13例,年纪(57±11.5)岁,兼并糖尿病4例,高脂血症9例,高血压17例。冠状动脉造影查看示冠状动脉无狭隘且血流正常者36例为正常对照组,其间男21例,女15例,年纪(55.0±12.1)岁,兼并糖尿病5例,高脂血症11例,高血压20例。两组的一般材料比较,差异无计算学含义(P>0.05)。以TIMI血流计帧法[1]为计量目标:以30帧/s的速度收集图画,计数造影剂从进入某支冠状动脉并占满近端整个宽度,终究一帧为造影剂抵达各支冠状动脉的远端符号,其间前降支为远端分叉处,通常在心尖部,回旋支为最远端的分叉,右冠状动脉为后降支宣布后的第1个分支。一般公认的正常冠状动脉的血流速度(30帧/s的记载速度下)在前降支为(36.2±2.6)帧,左旋支为(22.2±4.1)帧,右冠状动脉为(20.4±3.0)帧,均匀为(21.0±3.1)帧。将TIMI帧数大于冠状动脉正常血流速度的两个标准差界说为SCF。均匀TIMI血流帧数为该患者3支血管的均匀值。

1.2 办法

一切受检者经桡动脉或股动脉途径使用Judkins法行冠状动脉造影,在冠状动脉造影的第2天清晨空腹抽取静脉血送检,hs-CRP、空腹血糖、肝功用、肾功用、血脂全套选用日立7600-020全自动生化剖析仪测定,其间hs-CRP正常值<10 mg/L。

1.3 计算学处理

数据使用SPSS 16.0计算软件包进行计算学处理,计量材料以x±s标明,选用t查验,相关性选用Pearson线性相关剖析,以P<0.05为差异有计算学含义。

2 成果

SCF组的冠状动脉TIMI血流帧数显着大于对照组(P<0.01)(表1)。SCF组的血清hs-CRP水平为(16.8±3.9)mg/L,显着高于对照组的(7.2±2.8)mg/L(P<0.05)。以3支冠脉血流的均匀帧数与hs-CRP进行Pearson线性相关性剖析,成果显现均匀血流帧数与hs-CRP水平呈正相关(r=0.476,P<0.01)。

3 评论

CRP是一种炎症反响的时相蛋白,由细胞因子诱导肝脏发作,在正常人血液中含量极低,绝大多数正常人血清hs-CRP浓度<10 mg/L。国内外研讨早已标明血清hs-CRP水平对冠心病患者心血管不良事情风险具有重要的猜测价值。SCF的首要原因传统上被认为是微血管内皮功用失调[4],其依据来源于心肌安排病理活检[5-6],而导致微血管内皮功用失调的要害物质是内源性一氧化氮(NO),NO是一种内皮开释的血管舒张因子,是现在已知的调理血管张力的首要物质,内皮功用首要是指内皮开释NO的功用,标明慢血流患者内皮开释NO的功用受到了损害。国外体内实验研讨中发现,CRP经过内皮型一氧化氮合酶脱耦联效果引起NO水平下降,然后终究导致血管内皮功用不良[7]。本研讨成果显现,SCF组的血清hs-CRP水平较对照组显着升高,进一步证明了hs-CRP水平与SCF的发作密切相关,提示hs-CRP水平升高激活血管内皮炎症反响以及导致NO削减等效果参加了SCF的病理、生理进程,进一步估测hs-CRP水平升高是SCF发作的风险因子之一,下降hs-CRP应能够改进血管内皮功用,然后削减SCF的发作。别的,本研讨发现两组患者的均匀血流帧数与血清hs-CRP水平呈正相关,与Madak等[8]的研讨成果类似,提示炎症反响的参加与冠状动脉血流形式存在相互联系[9-10]。现在已有多位学者研讨他汀等药物关于SCF的医治效果[11-12],假以时日,必然会对有用防治SCF发作深远的影响。
