Fractional flow reserve as an indicator of coronary circulation with special reference to kidney... LETTER TO THE EDITOR Fractional flow reserve as an indicator of coronary circulation with special reference to kidney function Xaplanteris et al reviewed physiological indicators via Disclosure catheterization to know the level of coronary circulation. There is no conflict of interest in this study. Among them, fractional flow reserve (FFR) value has been used for evaluating severity of coronary stenosis. As there was no information on the relationship between Tomoyuki Kawada, MD, FFR and chronic kidney disease (CKD) in the article, I Department of Hygiene and Public Health, Nippon Medical School, 1-1-5 present some references. Sendagi, Bunkyo-Ku, Tokyo 113-8602, Tebaldietal evaluated the effect of CKD on FFR Japan; value in patients with intermediate coronary stenosis. CKD was defined as creatinine clearance value B45 ml/min, and FFR positive was defined as B0.80. References Adjusted hazard ratios (HRs) (95% confidence inter- 1.
