“…6 However, additional costs, need for further instrumentation of the infarct-related artery and for pharmacological induction of steady-state hyperemia have deeply restricted the widespread use of IMR in everyday clinical practice, especially in the emergent setting of pPCI. 15 NH-IMR angio has been recently proposed as a pressure-wire-free measure of myocardial reperfusion and CMI that can be easily calculated at completion of pPCI from standard angiographic views without requiring additional procedural steps, adenosine infusion, or extraprocedural time (Figure 1). This readily available tool was described for the first time in 2020 by De Maria et al 7 and it has demonstrated to be a valuable alternative to the invasively measured IMR or to microvascular obstruction at CMR for the detection of post-STEMI CMI.…”

“…In parallel, the ongoing development of angiography-based tools using 3-dimensional modeling and simplified computational flow-dynamics techniques to derive microvascular function surrogates could facilitate risk stratification as it avoids the additional costs, procedural time, and complexity associated with the use of a pressure wire. 18…”

“…This is certainly a limiting factor towards a broader implementation of IMR in pPCI as it requires additional procedural time, costs, and procedural risks. Various versions of angiography-derived IMR have been proposed in recent years, all showing good diagnostic accuracy in detecting an abnormal IMR (comparable to its invasive counterpart), and good correlations with clinical outcomes and MVO detection using cMRI in STEMI patients [134,135]. More recently, angiography-derived IMR (namely, IMR angio ) has shown a 98% negative predictive value in ruling out the occurrence of in-hospital and 30-day adverse events in STEMI patients, configuring itself as a promising tool to non-invasively risk-stratify STEMI patients [136].…”
