【摘要】：目的探討慢性穩(wěn)定性心絞痛患者冠狀動(dòng)脈臨界病變血管內(nèi)超聲斑塊影像學(xué)特征。方法對(duì)慢性穩(wěn)定性心絞痛患者行冠狀動(dòng)脈造影檢查,對(duì)冠狀動(dòng)脈造影顯示為臨界病變者,行血管內(nèi)超聲檢查,評(píng)估斑塊特征。結(jié)果 163例冠狀動(dòng)脈臨界病變患者中薄帽纖維粥樣硬化斑塊(TCFA)、厚帽纖維粥樣硬化斑塊(ThCFA)患者分別為37、50例。TCFA、ThCFA患者臨床特征、冠狀動(dòng)脈分布情況差異無統(tǒng)計(jì)學(xué)意義;超過50%的臨界病變血管在左冠狀動(dòng)脈前降支;ThCFA患者平均斑塊負(fù)荷、斑塊面積高于TCFA患者;ThCFA及TCFA患者斑塊成分以纖維組織最多,其次為纖維脂肪組織和壞死核心成分,高密度鈣化面積最低。TCFA患者最小管腔面積≤4.0mm2者占18.92%(7/37),顯著高于ThCFA患者。結(jié)論慢性穩(wěn)定性心絞痛冠狀動(dòng)脈臨界病變ThCFA患者斑塊負(fù)荷更重,管腔面積更大。TCFA患者最小管腔面積≤4.0mm2比例更高。
[Abstract]:Objective to investigate the imaging features of intravascular ultrasound plaque in patients with chronic stable angina pectoris. Methods Coronary angiography was performed in patients with chronic stable angina pectoris. Results among the 163 patients with critical coronary artery disease, the clinical characteristics of thin cap atherosclerotic plaque (TCFA), thick cap atherosclerotic plaque (ThCFA) were 37 / 50, respectively. There was no significant difference in the distribution of coronary artery. More than 50% of critical diseased vessels had average plaque load in patients with left anterior descending branch of coronary artery, and the plaque area was higher than that in TCFA patients and TCFA patients, followed by fibrous adipose tissue and necrotic core components. The minimum lumen area 鈮，
