摘要:
目的 探讨动态检测基质金属蛋白酶(MMP)1、MMP9在经皮冠脉介入术后再狭窄的意义。方法 对206例经皮冠脉介入(PCI)术后患者进行造影及冠脉血管内超声(IVUS)检查随访,造影证实再狭窄组32例,共38处病变;无再狭窄组174例,共229处病变。测量并比较两组外弹力膜横截面积、斑块面积、最小管腔面积及内膜增生面积;术前及随访时均行MMP检测,比较两组PCI前后MMP1、MMP9变化;按最小管腔面积(MLA)分为MLA > 5 mm2、MLA 3 ~ 5 mm2及MLA < 3 mm2组,比较3组的MMP1、MMP9水平。结果  与无再狭窄组比较,再狭窄组有更大的斑块面积、内膜增生面积及更少的最小管腔面积;两组患者术前及术后的MMP1水平无明显差异,无再狭窄组PCI前后MMP9水平无明显差异,再狭窄组术后MMP9明显升高,手术前后分别为(2.03 ± 0.56)ng/ml 比 (2.89 ± 0.33)ng/ml(P < 0.05);MMP1水平与MLA面积无关;MMP9水平在MLA > 5 mm2组明显低于MLA 3 ~ 5 mm2及MLA < 3 mm2,各为(1.45 ± 0.32)ng/ml、(2.93 ± 0.45)ng/ml 和 (3.09 ± 0.65)ng/ml,三组间差异有统计学意义(P < 0.05);后两组比较差异无明显统计学意义(P > 0.05)。结论  PCI后支架内再狭窄患者MMP9水平较术前升高,但与再狭窄程度无关。
