Key result
FFR-CT guidance is linked to fewer invasive angiograms showing no obstructive CAD versus usual care.
Why the study?
Does a fractional flow reserve by computed tomographic angiography (FFRCT)-guided diagnostic strategy reduce the rate of invasive angiography showing no obstructive CAD compared to usual care in patients with suspected coronary artery disease?
Does a fractional flow reserve by computed tomographic angiography (FFRCT)-guided diagnostic strategy reduce the rate of invasive angiography showing no obstructive CAD compared to usual care in patients with suspected coronary artery disease?
An FFRCT-guided diagnostic strategy safely reduces the rate of unnecessary invasive coronary angiograms that show no obstructive CAD in patients with suspected disease.
FFRCT may reduce unnecessary invasive angiography; leaves open whether RCTs confirm benefit in suspected CAD.
Computed tomographic angiography/fractional flow reserve by CTA was a feasible and safe alternative to ICA and was associated with a significantly lower rate of invasive angiography showing no obstructive CAD.
