understand routine use of FFR and alternate indices in clinical practice. This study will determine the use and clinical outcome of FFR-guided PCI in patients presenting with stable coronary artery disease, as well as in patients presenting with Acute Coronary Syndrome (ACS) on culprit and non-culprit lesions at index and secondary procedures. The study will also collect the routine use of coronary physiologic measurements of adenosine-induced hyperemia FFR, Pd/Pa, FFR by contrast-induced hyperemia, and other alternate indices measurements.
