Clinical Value of Coronary Computed Tomographic Angiography in Patients With Stable Angina.

Over the past decades, great strides have been made to establish coronary computed tomographic (CT) angiography within the field of cardiovascular medicine. The diagnostic accuracy of CT in comparison with invasive angiography was demonstrated in numerous singleand multicenter studies. From large registry data, an understanding developed of how cardiac CT could affect therapeutic management within different clinical contexts. Most recent clinical practice guidelines support the use of cardiac CT as a primary or secondary diagnostic option for patients with stable chest pain symptoms. As a last step toward full recognition, several randomized clinical trials were conducted to investigate the effect of cardiac CT on clinical outcome in comparison with established noninvasive strategies.
