Cost Effectiveness and Utility of Computed Tomography Angiography (CTA) and Cardiac Cath
This is a research study to determine patient preferences between two different diagnostic tests; a CT angiogram (CTA) and a catheter angiogram, both of which are used at the University to screen for and detect heart disease.
|Study Design:||Observational Model: Case Control
Time Perspective: Prospective
|Official Title:||Cost Effectiveness and Utility of Coronary Artery Computed Tomography Angiography (CTA) in Screening for Coronary Artery Disease|
- Utility of CT and catheter angiography [ Time Frame: Within 6 months of testing with CT and catheter angiography ] [ Designated as safety issue: No ]Utility of CT and catheter angiography was compared within patients who had both tests performed.
|Study Start Date:||October 2006|
|Study Completion Date:||November 2012|
|Primary Completion Date:||October 2012 (Final data collection date for primary outcome measure)|
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.
