Primary Outcome Measures:
  • Utility of CT and catheter angiography [ Time Frame: Within 6 months of testing with CT and catheter angiography ]
    Utility of CT and catheter angiography was compared within patients who had both tests performed.

Enrollment: 31
Study Start Date: October 2006
Study Completion Date: November 2012
Primary Completion Date: October 2012 (Final data collection date for primary outcome measure)
Intervention Details:
    Other: Survey
    To determine patient preference for the two tests CT angiography (CTA) and catheter coronary angiography (CCA).
Detailed Description:
This is a single site study that will retrospectively and prospectively identify and enroll 100 subjects, both male and female, 18 years of age and older who undergo both coronary angiography and coronary artery computed tomography (CT), using the electronic radiology and cardiology databases. The purpose is to conduct a survey to assess their preference for either test to diagnose coronary artery disease. Subjects should be within six months of having the tests to avoid memory and recall problems.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
