Though the diagnostic properties of Age/Sex/Gene Expression Score (ASGES) or Corus CAD have been evaluated in previous observational studies, there are limited data regarding how primary care clinicians are using the results of the test in the care and management of patients with symptoms suggestive of angina in the African-America patient population. This retrospective study is designed to examine the relationship between the Corus CAD score and patterns of care regarding cardiology referral or further cardiac diagnostic testing in an African-American patient population single-center site.
