The findings offer a potential route for more patients with suspected coronary artery disease (CAD) to receive functional assessment of lesions without the need for a guidewire or hyperemic agents.

Fearon, MD, with Stanford University School of Medicine, and colleagues assessed 319 vessels from 301 patients with stable angina, unstable angina or non-ST elevation myocardial infarction. They performed both conventional angiography and pressure-wire based FFR and analyzed how well the angiography-derived FFR—using the proprietary software—matched the more invasive FFR measurements.

But uptake of guidewire-based FFR has lagged, Fearon and colleagues noted.
