Why the study?
FFR improves outcomes and lowers cost in elective coronary angiography, but nationwide surveys show low usage, prompting investigation into actual usage among elderly patients.
What is the utilization rate of fractional flow reserve during elective coronary angiography among elderly patients in the US?
What is the utilization rate of fractional flow reserve during elective coronary angiography among elderly patients in the US?
Despite known benefits, FFR utilization remains low at 6.3% among elderly patients undergoing elective coronary angiography in the US.
Answers are grounded in this paper and cite their sources.
FFR remains underused in elderly elective angiography patients; confirms nationwide low adoption and leaves open barriers to uptake.
Fractional flow reserve (FFR) is a physiologic measurement of coronary artery perfusion. Studies have demonstrated its benefit in lowering cost and improving outcomes in patients undergoing elective coronary angiography, though follow-up surveys have demonstrated low usage nationwide. We sought to investigate the actual usage in elderly patients undergoing elective coronary angiography. Overall utilization of FFR for elective coronary angiography was 6.3%. Age, sex, race, prior stress testing and region of the country were all statistically significant predictors for FFR use. There still exist many barriers to widespread adoption of this modality, which require further exploration.
