FFR changes coronary management in one-third of patients


 

REPORTING FROM SCAI 2019

“We’ve known for some time that angiography alone can lead to overtreatment,” commented Philippe Généreux, MD, an interventional cardiologist at Morristown (N.J.) Medical Center. “With FFR, physiology is the key to optimizing outcomes.”

FFR by wire may soon be obsolete

The PRESSUREwire study included 2,217 consecutive patients who underwent FFR assessment at 70 centers in 15 countries during October 2016–February 2018. The only exclusions were patients with extremely tortuous or calcified arteries or patients with a bypass graft to the target vessel. Enrolled patients averaged 65 years of age, and three-quarters were men; 63% had stable coronary disease, 31% had acute coronary syndrome, and the remainder had silent ischemia documented by noninvasive testing. A stenosis of 50%-69% occluded 54% of the tested coronaries; 24% had a 70%-90% occlusion; 20% had an occlusion of less than 50%; and the remaining patients had an occlusion of more than 90%.

While the overall percentage of patients whose treatment plan changed following FFR assessment shifted moderately, the changes within each treatment category were more striking. For example, among the 62% of all patients initially designated for medical management based on angiography, the FFR findings changed the management plan to PCI in 19% of this subgroup. Conversely, among the 33% of all patients initially designated for PCI based on angiography, 52% instead received medical management based only on their FFR results. Because shifts in treatment strategy following FFR had some patients go from medical management to PCI, and others went from PCI to medical, overall the percentage of patients who received medical management without immediate revascularization had just a modest up-tick, from 62% before FFR to 67% after, Dr. Schampaert said.

PRESSUREwire was funded by Abbott Vascular, a company that markets an FFR device. Dr. Schampaert has been a consultant to Abbott Vascular as well as AstraZeneca, Bayer, Medtronic, Volcano-Philips, Sanofi, and Servier. Dr. Alaries had no disclosures. Dr. Généreux has been a consultant to Abbott Vascular and to several other companies, and he has an equity interest in Saranas.
