64排螺旋CT冠脉成像对冠心病心绞痛患者冠脉狭窄及斑块状态的评估价值

Evaluation value of 64 row spiral CT coronary imaging for coronary stenosis and plaque status in patients with coronary heart disease and angina pectoris

摘要:

目的 探讨分析64排螺旋CT冠脉成像对冠心病心绞痛患者冠脉狭窄及斑块状态的评估价值。方法 选取2020年10月至2023年10月洛阳市第三人民医院收治的116例冠心病心绞痛患者，所有患者均接受64排螺旋CT冠脉成像检查，并经冠脉造影检查确诊，对照分析64排螺旋CT冠脉成像的价值。结果 冠脉造影检出冠脉狭窄病变205处，64排螺旋CT冠脉成像检出198处。64排螺旋CT冠脉成像检查冠脉狭窄的灵敏度为95.61％，特异度为99.67％，符合率为98.65％，与冠脉造影检查结果比较，差异无统计学意义（P>0.05）。冠脉造影检出轻度狭窄率为20.00％，中度狭窄率为37.56％，重度狭窄率为42.44％；64排螺旋CT冠脉成像分别检出17.17％、34.85％、47.98％，与冠脉造影检查结果比较，差异无统计学意义（P>0.05）。64排螺旋CT冠脉成像检查显示，稳定型心绞痛与不稳定型心绞痛患者狭窄程度、斑块状态比较，差异有统计学意义（P<0.05）。结论 64排螺旋CT冠脉成像诊断评估冠心病心绞痛患者冠脉狭窄及斑块状态效果确切，能有效检出冠脉狭窄病变及狭窄程度、斑块性质，值得推广。

Abstract:

Objective To explore and analyze the value of 64 slice spiral CT coronary imaging in evaluating coronary stenosis and plaque status in patients with coronary heart disease and angina pectoris.Methods From October 2020 to October 2023, 116 patients with coronary heart disease and angina pectoris were admitted. All patients underwent 64 slice spiral CT coronary imaging examination and were confirmed by coronary angiography. The value of 64 slice spiral CT coronary imaging was compared and analyzed.Results Coronary angiography detected 205 coronary stenosis lesions, and 64 slice spiral CT coronary imaging detected 198 lesions. The sensitivity, specificity, and accuracy of 64 slice spiral CT coronary angiography for detecting coronary stenosis were 95.61%, 99.67%, and 98.65%, respectively. There was no significant difference compared with the results of coronary angiography (P>0.05). The rate of mild stenosis detected by coronary angiography was 20.00%, the rate of moderate stenosis was 37.56%, and the rate of severe stenosis was 42.44%; 64 slice spiral CT coronary imaging detected 17.17%, 34.85%, and 47.98%, respectively, with no significant difference compared with the results of coronary angiography (P>0.05). Sixty-four row spiral CT coronary imaging examination showed significant differences in the degree of stenosis and plaque status between patients with stable and unstable angina pectoris (P<0.05).Conclusion Sixty-four slice spiral CT coronary imaging is effective in diagnosing and evaluating coronary artery stenosis and plaque status in patients with coronary heart disease and angina pectoris. It can effectively detect coronary artery stenosis lesions, the degree of stenosis, and the nature of plaque, and is worth promoting.
