Comparative study and application choice of coronary angiography and coronary CTA in the diagnosis of coronary artery stenosis
冠状动脉血管造影与冠脉CTA在冠脉狭窄诊断中的对比研究及应用选择

摘要

目的 随着冠心病发病率的持续上升，冠脉狭窄的精准诊断成为临床治疗的关键环节，因此本文探析冠状动脉血管造影与冠脉CTA在冠脉狭窄诊断中的应用及价值。方法 对我院心内科就诊的疑似冠心病患者分别采取冠状动脉血管造影与冠脉CTA检查，以冠状动脉血管造影为冠脉狭窄诊断的金标准，对比冠脉CTA检查准确率。结果 冠脉CTA检查准确率、狭窄检出情况和狭窄程度与冠脉造影无明显差距，P＞0.05说明差异无统计学意义。结论 两种检查方法各具特色，临床实践中应遵循“阶梯式”应用原则，初筛阶段优先采用CTA排除明显异常，对可疑病例再行冠状动脉血管造影确诊。

Abstract

Objective With the continuous increase of the incidence rate of coronary heart disease, the accurate diagnosis of coronary stenosis has become a key link in clinical treatment. Therefore, this article explores the application and value of coronary angiography and coronary CTA in the diagnosis of coronary stenosis.
Methods Coronary angiography and coronary CTA were performed on suspected coronary heart disease patients who visited our cardiology department. Coronary angiography was used as the gold standard for diagnosing coronary stenosis, and the accuracy of coronary CTA was compared.
Results There was no significant difference in the accuracy, stenosis detection, and degree of stenosis between coronary CTA examination and coronary angiography, with P>0.05 indicating no comparative significance.
Conclusion   Both examination methods have their own characteristics, and in clinical practice, the “step-by-step” application principle should be followed. CTA should be prioritized in the initial screening stage to exclude obvious abnormalities, and coronary angiography should be performed to confirm suspicious cases.
