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.
