Coronary calcium scoring can be trusted to guide cardiac test selection

Coronary artery calcium scanning predicts the risk of myocardial infarction and sudden death accurately enough to guide the selection of diagnostic tests for symptomatic patients, according to a multicenter prospective study. The Early Identification of Subclinical Atherosclerosis by Noninvasive Imaging Research (EISNER) study, led by Leslee J. Shaw, Ph.D., at Emory University in Atlanta, also indicates the multislice CT-based calcium tests can be used without triggering unnecessary exams or expense. Researchers at Cedars-Sinai Medical Center and Harbor-UCLA Medical Center, both in Los Angeles, St. Luke’s-Roosevelt Hospital and Weill Cornell Medical College, both in New York City, and the University of California at Irvine participated in the study. Findings appeared in the Sept. 29 issue of the Journal of the American College of Cardiology.
