Prognostic Value of CT Angiography in Patients With Inconclusive Functional Stress Tests

Objectives We attempted to determine the prognostic value of coronary computed tomographic angiography (CTA) in patients with inconclusive functional stress tests. Background Patients with suspected coronary artery disease (CAD) and inconclusive noninvasive cardiac stress tests represent a frequent...

Zusammenfassung:	Objectives We attempted to determine the prognostic value of coronary computed tomographic angiography (CTA) in patients with inconclusive functional stress tests. Background Patients with suspected coronary artery disease (CAD) and inconclusive noninvasive cardiac stress tests represent a frequent management challenge. Methods We examined 529 consecutive patients with suspected CAD and prior inconclusive functional stress tests. All patients underwent a coronary CTA scan using a 64-slice multidetector row scanner. CAD severity by coronary CTA was categorized as: 1) no evidence of CAD; 2) nonobstructive coronary plaques (
