    Quantitative flow ratio is the technique to assess the degree of ischemia in a coronary vessel and derive the fractional flow reserve (FFR) without the conventional use of a pressure wire or induction of hyperemia. We believe that this technique advances the field forward by using 3D reconstruction of the entire coronary tree and using computer generated automatic lumped modeling for the calculation of QFR. Statistics reported on the comparison of invasive fractional flow reserve (FFR) and the newly introduced QFR are exceedingly high for a new diagnostic tool. However, there are still a few hurdles in the way.

    Keeping a stable blood pressure (BP) during hemodialysis is one of the important goals for End Stage Renal Disease (ESRD) patients. Maintaining a stable dry weight and controlling cardiovascular risk factors requires well controlled blood pressure with regular measurements. Accurate blood pressure measurement is a key element used during hemodialysis to identify and prevent hypotension with its possible target organ hypoperfusion. Whether there is a difference between using the central or peripheral BP measurements among End Stage Renal Disease (ESRD) patients during hemodialysis is still not clear. To identify the significant difference between the central and peripheral BP we tested the central and peripheral blood pressure in14 ESRD patients during full dialysis sessions. Over 326 peripheral BP readings were compared with 326 central BP measurements. A significant difference was noticed with a lower central systolic and pulse pressure and a higher central diastolic and Mean arterial pressure (MAP) as compared with the peripheral pressure readings. Since blood pressure measurement is the major factor to determine target organ hypoperfusion during hemodialysis, ignoring the central pressure measurements during hemodialysis could carry the risk of inducing unnoticed target organ hypoperfusion during hemodialysis.
