Despite successful PCI and complete revascularization, about 25% of patients will present with angina and/or positive exercise testing during follow-up. With recurring or persistent symptoms, a number of those patients will be referred for control angiography. This might create a significant burden for health systems as well as putting patients to undergo further interventions without clear demonstration of ischemia.~Assessing physiology and fractional flow reserve in particular after PCI could represent a further step to determine whether stent implantation and stenosis removal will be effective to relieve subjective and objective signs of ischemia.~Hypothesis:~Resting gradients such as whole cycle Pd/Pa and diastolic dPR and FFR will be abnormal (below ischemic threshold) in > 20% of cases despite optimal stent implantation and angiographic result.~The use of physiology assessment in previously intervened vessels in patients referred for persisting or recurring angina might help operators to decide upon further intervention.
Despite optimal angiographic result after stent implantation, a number of patients will undergo repeat angiography within 1 year of index procedure. EASY-PRIPCI is an observational study evaluating the incidence of abnormal physiology results in patients undergoing repeat angiography after uncomplicated percutaneous intervention (PCI).
