56% of those who passed then flunked scan for hardening of arteries

TUESDAY, Aug. 17 (HealthDayNews) -- Standard exercise stress tests may not detect latent hardening of the arteries, says a Cedars-Sinai Medical Center study in the Aug. 18 issue of the Journal of the American College of Cardiology.
The results suggest that additional screening for coronary calcium using X-ray computed tomography (CT) scanning could prove useful even when patients have normal stress test results. As deposits of calcium rise in heart arteries, so too do risks for heart attack.
"A relatively high number of patients who had normal readings on their stress tests had a calcium score of greater than 100, a score that is accepted as implying the need for aggressive medical treatment," Dr. Daniel Berman, director of cardiac imaging at the S. Mark Taper Foundation Imaging Center at Cedars-Sinai, said in a prepared statement.
