Advanced CT scans accurately assess coronary blockages
Date:8/28/2012

An ultra-fast, 320-detector computed tomography (CT) scanner can accurately sort out which people with chest pain need or don't need an invasive procedure such as cardiac angioplasty or bypass surgery to restore blood flow to the heart, according to an international study. Results of the study, which involved 381 patients at 16 hospitals in eight countries, are scheduled to be presented at the European Society of Cardiology Congress in Munich, Germany, on August 28.

"The CORE 320 study is the first prospective, multicenter study to examine the diagnostic accuracy of CT for assessing blockages in blood vessels and determining which of those blockages may be preventing the heart from getting adequate blood flow," says Joao A. C. Lima, M.D., senior author of the study and professor of medicine and radiology at the Johns Hopkins University School of Medicine. "We found an excellent correlation in results when we compared the 320-detector CT testing with the traditional means of assessment using a stress test with imaging and cardiac catheterization."

The study findings, says Lima, would apply to people who have chest pain but are not having a heart attack. Many people in that situation are sent to a cardiac catheterization laboratory for further evaluation with angiography, an invasive test to look for blockages in the coronary arteries using dye and special X-rays. About 30 percent of people who have such catheterization are found to have minimal disease or no blockage requiring an intervention to open or bypass the vessel.

Lima explains that a nuclear medicine stress test with imaging, known as SPECT, shows reduced blood flow to the heart without indicating the number or specific location of blockages.

The 381 patients who completed the study had traditional SPECT tests and invasive angiography. They also had two types of tests with a non-invasive 320-detector CT scanner. In the first CT test, the scanner was used to se
