Using computed tomographic angiography as a screening tool for low-risk, asymptomatic heart patients does not offer much benefit, according to a study of 2,000 patients in the May 23 Archives of Internal Medicine (link).

The testing did reveal plaque buildup in the heart vessels of 21% of patients, who were much likelier than patients who were not tested to be prescribed statins, receive cardiac catheterization or be sent for stress tests. However, after 18 months there was no difference between the two groups of patients on outcomes such as heart attacks and cardiac death.

"Our data are consistent with current guidelines by the American Heart Assn. that screening CT angiography should not play a role for low-risk patients who do not have symptoms," said Roger Blumenthal, MD, co-author of the study and director of the Johns Hopkins Ciccarone Center for the Prevention of Heart Disease in Baltimore.
