Coronary CTA a cost-effective alternative to cardiac catheterization for the evaluation of CAD
Date:4/21/2010

PHILADELPHIA According to a study conducted at Thomas Jefferson University (TJU), non-invasive coronary computed tomography angiography (CTA) is a cost-effective alternative to invasive cardiac catheterization in the care of patients who have positive stress test results but a less than 50 percent chance of actually having significant coronary artery disease (CAD). The study will be published in the May issue of the American Journal of Roentgenology (www.ajronline.org). CAD is a narrowing of the blood vessels that supply blood and oxygen to the heart. If left untreated, it can lead to a heart attack.

"Patients with positive stress test results but no heart-related symptoms, as well as patients with a positive stress test with atypical chest pain often receive referrals for cardiac catheterization for the evaluation of CAD," said the study's lead author, Ethan J. Halpern, M.D., professor, Department of Radiology at Jefferson Medical College, and director, Cardiac CT at Thomas Jefferson University Hospital. "Coronary CTA is an alternative, non-invasive diagnostic imaging test that can be used to effectively triage these patients."

The study compared the false-negative rates, false-positive rates, costs, and radiation exposure of direct referral of patients for cardiac catheterization with the values associated with performing coronary CTA before catheterization.

"At a 50 percent prevalence of CAD, we found that performing coronary CTA before cardiac catheterization results in an average cost saving of $789 per patient with a false-negative rate of 2.5 percent and average additional radiation exposure of 1-2 mSv, which is minimal," said Dr. Halpern.

According to the study results, when a patient with an expected CAD prevalence less than 85 percent is found to have a positive stress test result, coronary CTA is a less expensive alternative to direct performance of cardiac cat
