Figure 1 Example of a hemodynamic recording assessing coronary vessel physiology. In the upper half of the figure, a graph illustrates aortic pressure (Pa), distal pressure (Pd), and the Pd/Pa ratio, represented in red, green, and yellow, respectively. On the right side, key indicators for assessing coronary vessel function, such as fractional flow reserve (FFR), index of microcirculatory resistance (IMR), and coronary flow reserve (CFR) are displayed. These indicators provide essential information for evaluating coronary flow. The recording was obtained using the PressureWire X Guidewire during a routine follow-up coronary angiography. The figure was created in RadiView 2.0, Radi Medical Systems AB (Uppsala, SE).
