Study Description
Brief Summary:
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.

Condition or disease Intervention/treatment
Heart Diseases Other: Survey

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.
