摘要(Abstract):
目的通过测定不同类型冠心病患者血浆白三烯-B4(LT-B4)的水平,探讨其与冠心病(CHD)及冠状动脉病变的关系。方法入选400例患者,冠心病组310例,其中急性冠状动脉综合征(ACS)组217例,稳定性心绞痛(SAP)组93例,对照组90例。检测患者外周血浆LT-B4浓度。同时经选择性冠状动脉造影检查,明确冠状动脉病变情况。CHD组中85例患者接受64层螺旋CT冠状动脉成像检查,对冠状动脉内的主要斑块进行评价。结果冠心病组LT-B4水平明显高于对照组(t=12.365,P<0.05),ACS组LT-B4水平又明显高于SAP组(t=7.664,P<0.05)。随冠状动脉病变类型和冠状动脉病变程度的加重,LT-B4浓度逐渐升高;CHD患者的软斑块组、纤维斑块组较钙化斑块组血浆LT-B4浓度明显升高,差异有统计学意义;逐步回归分析表明LT-B4浓度与冠状动脉病变Gensini评分有显著相关性。结论 ACS患者白三烯-B4水平增高,并与冠脉病变的严重性明显正相关,血浆白三烯-B4检测结合64层螺旋CT测定能否提高判断ACS患者冠状动脉斑块性质的准确性,对ACS的诊断及对冠脉病变的判断有一定的预测作用。
