The purpose of this project is to examine the effectiveness of computed tomographic angiography (CTA) in patients with non-ST elevation acute coronary syndrome (NSTE-ACS). People who are hospitalized with this situation often require an angiogram to assess the heart and its arteries.
Recent advancements in technology have enabled CTA to clearly define coronary artery anatomy with great accuracy and to guide treatment strategies in select patient populations. We are investigating that CTA may be used, as an alternative to conventional angiograms, for the risk stratification of patients with high risk NSTE-ACS.
Patients eligible for the study will be high risk NSTE-ACS and awaiting an angiogram. Enrolled patients will undergo CTA prior to the angiogram. With each CTA the patient will be injected with a small dose of an X-ray dye and will be asked to lie still on the "scanning bed" for a period of 5-10 minutes.

Procedure: Computed Tomographic Angiography
- Operating Characteristics of CTA [ Time Frame: 1 month ]
- To compare the accuracy of CTA to CICA in predicting the mode of revascularization (PCI versus CABG) in NSTE-ACS patients. [ Time Frame: 1 month ]
- To determine the number of "avoidable" CICA (i.e. those accurately designated to medical therapy or surgery with CTA). [ Time Frame: 1 month ]
