More sophisticated healthcare brings higher costs, and today physicians are responsible for both high-quality and fiscally responsible care. Cardiologist Andrew Waxler, MD, FACC, believes that finding the right test for the right patient is one way to do both.

He cites the example of the Corus® CAD test, an inexpensive blood-based gene expression test that that can help physicians rule out obstructive coronary artery disease (CAD) in patients presenting with symptoms suggestive of CAD. With a negative predictive value of 96%, this decision tool can help avoid unnecessary and costly procedures such as cardiac catheterization and guide physicians toward the next steps in patient management.
