WebThe instantaneous wave-free ratio ( iFR, sometimes referred to as the instant wave-free ratio or instant flow reserve) is a diagnostic tool used to assess whether a stenosis is causing a limitation of blood flow in coronary arteries with subsequent ischemia. iFR is performed during cardiac catheterisation ( angiography) using invasive coronary … WebTherefore, post-PCI iFR was available in 520 vessels from 467 patients . Median follow-up duration was 375 days (IQR: 368-389 days). An iFR of <0.95 was identified as the best cutoff value to discriminate cardiac death or spontaneous MI during 1-year follow-up (area under the curve: 0.74; 95% CI: 0.61-0.88) (Supplemental Figure 1).
