| 摘 要： | 目的:探讨定量经静脉心肌声学造影(MCE)对冠脉非闭塞性病变经皮冠状动脉介入术(PCI)前后心肌灌注水平的评价。方法:以我科收治的29例行选择性冠状动脉造影术的患者为研究对象,根据造影结果分为A组:血管正常(对照组);B组:血管狭窄程度为75%～90%;C组:血管狭窄程度>90%。所有患者造影前1～3天行MCE检查,19例成功进行PCI治疗患者术后3～5天再行MCE检查。结果:PCI后MCE定量分析显示:B组的各参数值与A组比较均无明显差异;C组中β值和α×β值较A组明显降低(P<0.05)。同组PCI前后心肌灌注的比较:术后B组α值、β值与术前比较无明显差异,但α×β值较术前明显增加(P<0.05);C组的3个参数值α、β和α×β值与术前比较均无明显差异。结论:血管狭窄程度>90%的病变即使在成功PCI后局部心肌灌注水平仍较正常者低,而血管狭窄程度较轻组在成功实施PCI后心肌灌注良好。成功PCI后狭窄程度较轻组心肌灌注水平较术前有一定程度的改善,而狭窄程度较重组心肌灌注水平较术前改善不明显。

| Abstract: | Objective:The aim of this study was to evaluate myocardial reperfusion level in patients with coronary artery disease with coronary artery partial occlusion before and after percutaneous coronary intervention(PCI) using quantitative intravenous myocardial contrast echocardiography(MCE).Methods:The 29 patients who had undergone selective coronary angiography in our department were studied.According to the results of coronary angiography,the patients were divided into 3 groups:A,normal artery (control group);... |
