Utility of Noninvasive Testing Before Invasive Coronary Angiography in the Assessment for Revascularization.

ABSTRACT:

Objective

To examine the role of noninvasive testing (NIT) before invasive coronary angiography (ICA) by evaluating the association between a positive myocardial perfusion imaging (MPI) or computed tomography angiography (CTA) result and the decision to perform coronary revascularization.

Patients and methods

We screened all patients who received ICA between August 1, 2015, and July 31, 2019, and identified those who received MPI or CTA within the preceding 12 months. We considered MPI to be a positive result if it found moderate or severe ischemia in a specific coronary territory and CTA to be a positive result if it identified a stenosis greater than 50% in any major coronary artery.

Results

Of the 17,181 individual procedures, 2183 were included. Positive CTA had a
