To the Editor The study by Dr Muhlestein and colleagues1 showed that routine screening for coronary artery disease (CAD) using coronary computed tomography angiography (CCTA) among asymptomatic patients with type 1 or type 2 diabetes did not reduce all-cause mortality or major ischemic cardiovascular events during the 4-year follow-up. The Detection of Ischemia in Asymptomatic Diabetics (DIAD) study already has shown similar results using adenosine-stress radionuclide myocardial perfusion imaging.2 The DIAD study did not mandate any specific treatment plan for patients with abnormal screening test results.
