Brief Summary
This is a prospective, multi-center study to capture information on sensitivity and specificity of CADence using coronary angiogram as the gold standard, on subjects who are already scheduled for coronary angiography.

Outcome Measures
Primary Outcomes (1)
Percent of Participants With Positive Agreement of CADence Device Under Normal Use Conditions as Compared to Coronary Angiograms as Accurate and Appropriate
Angiographically significant stenosis was defined as 70% or greater stenosis in any major coronary artery. Percent of Participants with Positive Agreement of CADence Device Under Normal Use Conditions as Compared to Coronary Angiograms as accurate and appropriate. The study is used to determine two conditions. CADence = Positive for 70% or greater stenosis and CADence = Negative for less than 70% stenosis. The pre-specified intent of this Outcome Measure was to assess all study participants combined, irrespective of whether or not they participated in the Ambience main study or the repeatability and reproducibility sub-study.
24 hours or discharge from hospital, whichever is sooner
Secondary Outcomes (1)
Number of Participants With CADence-related Adverse Events
24 hours or discharge from hospital, whichever is sooner
Study Arms (2)
AMBIENCE
CADence System testing followed by coronary angiogram
AMBIENCE plus R&R Substudy
CADence System testing for repeatibility and reproducibility (4x by 2 operators) followed by coronary angiogram
