    Effects of stent postdilatation during primary PCI for STEMI: Insights from coronary physiology and optical coherence tomography

    Objectives This study aimed to assess the impact of stent optimization by NC‐balloon postdilatation (PD) during primary‐PCI for STEMI with the use of coronary physiology and intracoronary imaging. Methods This was a prospective observational study ( ClinicalTrials.gov :NCT02788396). Optical coherence tomography (OCT) and physiological measurements were performed immediately before and after PD with the operators blinded to all measurements. The index of microcirculatory resistance (IMR), coronary flow reserve (CFR) and fractional flow reserve (FFR) were measured. OCT analysis was performed for assessment of stent expansion, malapposition, in‐stent plaque‐thrombus prolapse (PTP) and stent‐edge dissections (SED). The ...
