CT Scans Can Spot Heart Trouble Fast
Date:3/26/2012

ful to screen low- to moderate-risk patients, Fonarow said.

"However, further studies are needed to evaluate the cost-effectiveness of this strategy and how it compares to protocols using high-sensitivity troponin tests," he added.

A troponin test measures the levels of one of two proteins, troponin T or troponin I, in blood, Fonarow explained. These proteins are released when the heart has been damaged, such as during a heart attack. However, this test is usually repeated over 12 to 16 hours, so the results do not come back as quickly as a CT scan.
