Assessing stable coronary artery disease

[摘要] To the Editor: The article by Nagaraja and Lincoff1 is an excellent review of the International Study of Comparative Health Effectiveness With Medical and Invasive Approaches trial. It highlights the continuing evolution of patient-centered approaches in the management of stable coronary artery disease. Their algorithm contains the phrase “cardiac computed tomography to assess calcium score and exclude left main disease.” Are the authors referring to the coronary artery calcium score (CACS) or coronary computed tomography angiography (CCTA)? I believe they mean the latter, but as both are computed tomographic modalities of the heart and the difference may not be readily appreciated by a general medicine audience, it may be helpful to clarify.
