Overall, the algorithm has “considerably high” discriminatory power for ruling out obstructive CAD, the authors wrote. When tested on the 126 patient group, it produced 73 true negatives, zero false negatives, 20 true positives and 33 false positives.
This, Glowacki et al. argued, allows clinicians to understand which patients should be sent on to receive CCTA exams. And in the current analysis, the algorithm would have prevented 73 unnecessary scans, sparing patients unneeded radiation and a risk of contrast-induced renal failure, the team concluded.
The full study was published last month in Academic Radiology.
