Rcadia COR Analyzer(R) System Demonstrates Potential in Emergency Department Triage of Chest Pain Patients at Low to Moderate Risk of Coronary Artery Disease
Date:11/30/2009

CHICAGO, Nov. 30 /PRNewswire/ -- Physicians at Beth Israel Deaconess Medical Center (Boston) reported today on results of a study demonstrating the potential for automated analysis of coronary CT angiography (cCTA) by Rcadia's COR Analyzer System® to assist in rapidly ruling out coronary artery stenosis in hospital emergency department (ED ) patients with chest pain. The ability of the automated system to enhance the use of cCTA has potential to significantly reduce unnecessary utilization of coronary observation beds in the low to moderate probability coronary artery disease (CAD) patient. The study, which describes the initial experience of the FDA-cleared system in analyzing cCTA images from ED patients, was presented in Chicago at the Radiological Society of North America (RSNA) Scientific Assembly and Annual Meeting.

Although an estimated six million patients enter the ED in the U.S. each year with chest pain, significant coronary disease is eventually ruled out in the vast majority. There are significant clinical and economic needs to improve this triage process for chest pain patients at low or moderate risk of CAD. Because current diagnostic techniques are often equivocal, an estimated two million, primarily low risk patients, are admitted to the hospital for further testing at an annual cost of $10-$13 billion. In an estimated 85 percent of these patients, acute coronary event is subsequently ruled out.

"In recent years, cCTA has proven to be an effective, non-invasive procedure for coronary artery analysis," said Girish Tyagi, MD, the study's principal investigator, radiologist at the medical center and Instructor at Harvard Medical School. "However, coronary CT angiography is under-utilized in the ED because the procedure relies on expert readers who may not be immediately available during 'off hours'. In our study, we asked whether this fully automated software tool could assist in patient triage by comparing
