Objectives: The aim of this study was to investigate the impact of post–percutaneous
coronary intervention (PCI) quantitative flow ratio (QFR) on clinical outcomes in patients with …

Fractional flow reserve (FFR) and instantaneous wave-free ratio are the present standard
diagnostic methods for invasive assessment of the functional significance of epicardial …

Objectives: The authors sought to evaluate the influence of coronary microcirculatory
dysfunction (CMD) on the diagnostic performance of the quantitative flow ratio (QFR) …

Background—The nonculprit lesion (NCL) management in ST-segment–elevation
myocardial infarction patients with multivessel disease is debated. We sought to assess …

Background—Fractional flow reserve (FFR), an index of the hemodynamic severity of
coronary stenoses, is derived from invasive measurements and requires a pressure …

Background. The study of coronary microcirculation has gained increasing consideration
and importance in cath lab. Despite the increase of evidence, its use still remains very …

(1) Background: In spite of the undeniable clinical value of the index of microvascular
resistance (IMR) in assessing the status of coronary microcirculation, its use globally …

Hemodynamics interacts with the cellular components of human vessels, influencing
function and healthy status. Locally acting hemodynamic forces have been associated—by a …

Aims: Despite the prognostic value of coronary microvascular dysfunction (CMD) in patients
with ST-segment-elevation myocardial infarction (STEMI), its assessment with pressure-wire …

Fractional flow reserve (FFR)-guided percutaneous intervention is superior to standard
assessment but remains underused. The authors have developed a novel “pseudotransient” …
