Abstract 263: The Use of a Blood-Based Age/Sex/Gene Expression Test Helped Define Symptomatic Patients Unlikely to Benefit From Additional Anatomic or Functional Cardiac Testing: A Case Series Analysis in the Outpatient Cardiology Setting
Abstract:Background:
More effective tactics are needed to evaluate patients with suspected symptomatic obstructive coronary artery disease (CAD). Results from recent studies such as PROMISE demonstrated that < 10% of these patients had a cardiac cause for their symptoms. A previously validated blood-based test, incorporating age, sex, and gene expression levels, demonstrated a 96% negative predictive value among symptomatic, non-diabetic patients in the evaluation of obstructive CAD at a threshold score … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
