[Abstract] Objective To investigate the effect of different doses rosuvastatin on plasma level of sOX40L and myocardial damage in acute myocardial infarction patients undergoing primary PCI. Methods 66 cases of acute myocardial infarction patients underwent primary PCI were enrolled.These patients were divided into two groups:A group(rosuvastatin 20 mg for pre-operation 12 h and rosuvastatin 20 mg, 1 times a night,for 7 days in post-operation),B group(placebo for pre-operation and rosuvastatin 10 mg,1 times a night,for 7 days in post-operation).The difference plasma level of sOX40L and hs-CRP were examined in designed time points between the two groups were observed. Results The differences of sOX40L and hs-CRP between the two groups were not obviously different before PCI(P>0.05),which with the levels of hs-CRP was(18.40±2.64),(17.95±2.72)mg/L,the levels of sOX40L was(30.24±18.14),(30.83±18.68)pg/ml.Between two groups,the level of sOX40L and hs-CRP were increased more distinctly at 24 hours after PCI as compared with before PCI(P<0.05),which with the levels of hs-CRP was(27.64±2.75),(28.18±2.91)mg/L,the levels of sOX40L was(38.71±17.36),(41.93±17.71)pg/ml.In the post-operation for 48 hours and 1 week,the level of sOX40L and hs-CRP were decreased more significantly in A group than those of B group(P<0.05). Conclusion PCI can increases the level of sOX40L and hs-CRP.For acute myocardial infarction patients undergoing primary PCI,treatments with high-dose rosuvastatin can decline inflammatory reaction,improve the stability of vulnerable plaque.

急性心肌梗死(acute myocardial infarction,AMI)急性期病死率约为30%,预后较差。现在经皮冠状动脉介入术(percutaneous coronary intervention,PCI)被广泛使用于AMI患者的心肌血流重建中,急性期行介入术医治使既往30%左右的住院逝世率下降至4%左右[1],证明其有助于改进预后,但另一方面现在以为PCI亦可诱导和加剧部分炎症反响,导致术后再狭隘或血栓构成以及缺血事情的再发作,构成心肌损害[2]。有研讨标明,安稳型心疼痛患者成功施行择期PCI后,约70%的患者呈现术后心肌坏死标志物的升高,与炎症因子联系密切。OX40L是冠心病新的促炎症介质,与急性冠状动脉事情发作率呈正相关;他汀类药物具有抗炎症、安稳斑块的作用,可下降缺血事情的发作。本项目针对AMI患者不同剂量瑞舒伐他汀对急诊PCI血浆sOX40L的影响进行了研讨。
1 材料与办法
1.1 一般材料
挑选2012年8月~2013年11月在我院心内科住院的AMI患者66例,一切当选患者均行急诊PCI。依据临床及冠状动脉造影成果确诊为AMI,其确诊规范参照中华医学会心血管病学分会、中华心血管病杂志修改委员会引荐和制定的AMI确诊和医治攻略。依据医治办法的不同将患者随机分为A组和B组。A组34例,其间,男性 18例,女人 16例;年纪51~77岁,均匀(65.7±8.4)岁。B组32例,其间,男性 17例,女人15例;年纪51~77岁,均匀(62.6±6.8)岁。扫除规范:兼并风湿性心脏病及扩张型心肌病等其他心脏疾病、感染性疾病、肿瘤及免疫性疾病、严峻心功用及肝肾功用不全、血液系统疾病、神经系统疾病、外周血管疾病、他汀类药物禁忌证、入院前调脂药物服药史。两组患者的性别、年纪等一般材料比较,差异均无统计学含义(P>0.05),具有可比性。
1.2 医治办法
A组:急诊PCI术前12 h内给予瑞舒伐他汀20 mg,术后20 mg口服,每晚1次,口服7 d。B组:术前口服安慰剂,PCI术后瑞舒伐他汀10 mg,每晚1次,口服7 d。两组患者支架置入数量、抗凝药物、硝酸酯药物、ACEI或ARB、β-受体阻滞剂的使用状况差异均无统计学含义(P>0.05)。
1.3 检测办法
一切患者分别在术前、术后24 h、48 h、7 d收集肘静脉血3 ml,置入EDTA抗凝管,3000 r/min离心15 min,别离上清血浆,在-80℃环境下保存。
1.3.1 血浆sOX40L的测定 严厉依照说明书操作。使用酶联免疫吸附法(ELISA)测定血浆sOX40L。向预先包被sOX40L抗体的包被微孔中,顺次参加标本、规范品、辣根过氧化物酶(HRP)符号的检测抗体。用封板膜封住反响孔,37℃恒温箱温育60 min。洗板机洗板5次。每孔参加底物TMB显色,37℃避光温育15 min,显蓝色后,每孔参加停止液。在450 nm波利益测定各孔OD值,经过规范曲线得到标本sOX40L浓度值。
1.3.2 高敏C反响蛋白(hs-CRP)的测定 使用免疫荧光双抗体夹心法。严厉依照说明书操作。
1.4 统计学办法
选用SPSS 14.0统计学软件对相关数据进行剖析,计量材料以均数±规范差(x±s)标明,两组间均数的比较选用t查验,以P<0.05为差异有统计学含义。
2 成果
两组间PCI术前sOX40L和hs-CRP水平比较,差异无统计学含义(P>0.05);PCI术后24 h两组患者sOX40L和hs-CRP水均匀较术前显着增高(P<0.05);PCI术后48 h及7 d,与B组比较,A组患者的sOX40L和hs-CRP水平显着下降(P<0.05)(表1)。
3 评论
急诊PCI是医治AMI的有用办法,但术后前期再发心肌缺血、心力衰竭、猝死等严峻不良心血管事情率仍较高,这些不良事情的发作与急性或亚急性支架内血栓构成、血管边支阻塞、支架再狭隘和心肌重构等多种要素有关,其病理生理机制或许与PCI诱导和加剧部分炎症反响、炎症因子介导心肌损害有关[3-4]。PCI时支架作为异物对部分安排发作影响,促进炎症因子开释;球囊扩张及支架置入机械损害构成血管内皮损害、斑块决裂激活炎症因子的表达[5]。Karaca等[6]发现PCI术后患者体内存在有一种被激活的、扩大的炎症反响,且与预后不良密切相关。sOX40L是血浆可溶性OX40L,属TNF宗族成员,是与急性冠状动脉综合征密切相关的新式炎症因子,在动脉粥样硬化构成及其临床结局中起到重要作用[7]。Wang等[8]研讨标明,简直在动脉粥样硬化斑块处的一切细胞中均可检测到OX40L的表达,但是在坏死的斑块中心及正常血管壁中简直检测不出。Ria等[9]研讨发现,在AMI人群中,编码OX40L基因序列中的一个变异基因呈现频率显着性增高,提示OX40L与AMI密切相关。OX4OL经过与OX4O结合,在按捺细胞的凋亡,添加CD4+T细胞的数量及功用,多种炎症因子开释及后续扩大的炎症免疫反响中均发挥极为重要的作用[10]。激活的T细胞是参加动脉粥样硬化进程的重要炎性致病要素[11]。hs-CRP是炎症的标志性因子,心血管疾病独立的风险因子[12],对猜测斑块易损性具有较高的准确度和灵敏度[13]。
他汀类药物独立于调脂的多效性已日益遭到重视,因其可以全面改进内皮的功用、减低炎症反响、抗氧化、安稳易损斑块,削减不良心脏缺血事情的发作。据文献报导,现在试验研讨中证明瑞舒伐他汀是第一个可以安稳反转动脉粥样硬化斑块、缩小斑块体积的他汀类调脂药物[14];ACS患者内行冠状动脉介入术前强化瑞舒伐他汀医治1年后首要不良心源性结尾事情(心源性逝世、非致死性心肌梗死等)相对安慰剂组下降显着[15]。本研讨成果标明,两组间PCI术前sOX40L和hs-CRP水平比较,差异无统计学含义(P>0.05);PCI术后24 h两组患者sOX40L和hs-CRP水均匀较术前显着增高(P<0.05),提示PCI或许诱发和加剧冠状动脉病变部分炎症反响;与B组比较,A组患者PCI术后48 h和7 d的sOX40L和hs-CRP水平显着下降(P<0.05),这一成果提示他汀类药物可有用地操控PCI术后炎症反响,且有剂量依赖性,前期使用较大剂量瑞舒伐他汀具有更强的按捺炎症作用,这或许是改进PCI术后不良冠状动脉事情发作的机制之一。
本研讨使用不同剂量瑞舒伐他汀对AMI行PCI患者进行干涉医治,调查血浆sOX40L与hs-CRP的改变状况,为改进AMI患者PCI术后的近、远期作用,下降炎症供给了科学依据。
