Brief Summary

Coronary CT angiography (CCTA) offers great promise as a risk stratification tool in patients with suspected CAD. It has been demonstrated in a multitude of accuracy studies to have a negative predictive value averaging over 95%. This leads to the hypothesis that a negative CCTA may preclude the need for invasive testing. The purpose of this randomized controlled study is to prospectively evaluate the role of CCTA on the management of patients with inconclusive or indeterminate stress test results.CCTA is able to provide not only information on presence and extent of coronary artery calcification, but detailed coronary anatomy as well. SPECIFIC AIM # 1: To evaluate the diagnostic and prognostic performance of CCTA in patients with equivocal / intermediate stress test results as compared to conventional invasive coronary angiography. SPECIFIC AIM # 2: To evaluate the utility of CCTA in prediction of major adverse cardiac events (MACE) compared to invasive coronary angiography at 30 days, 1 year, 3 years and 5 years.
