Fractional Flow Reserve in Patients With Prior Myocardial Infarction [PDF]

open access: yesCirculation, 2001
Background — Fractional flow reserve (FFR), an index of coronary stenosis severity, can be calculated from the ratio of hyperemic distal to proximal coronary pressure.

Fractional Flow Reserve–Guided Multivessel Angioplasty in Myocardial Infarction

open access: yesNew England Journal of Medicine, 2017
In patients with ST-segment elevation myocardial infarction (STEMI), the use of percutaneous coronary intervention (PCI) to restore blood flow in an infarct-related coronary artery improves outcomes. The use of PCI in non-infarct-related coronary arteries remains controversial.We randomly assigned 885 patients with STEMI and multivessel disease who had

Myocardial Contrast Stress Echo Versus Fractional Flow Reserve [PDF]

open access: yesCirculation: Cardiovascular Imaging, 2016
The ischemic potential of a coronary artery stenosis is revealed by physiological challenges, manifesting as myocardial malperfusion, and depending on the severity and duration of ischemia, mechanical and electric dysfunctions. Coronary pathophysiological changes can be measured either directly by translesional coronary pressure and flow or indirectly ...

Fractional Flow Reserve–Negative High-Risk Plaques and Clinical Outcomes After Myocardial Infarction [PDF]

open access: yesJAMA Cardiology, 2023
ImportanceEven after fractional flow reserve (FFR)–guided complete revascularization, patients with myocardial infarction (MI) have high rates of recurrent major adverse cardiovascular events (MACE). These recurrences may be caused by FFR-negative high-risk nonculprit lesions.ObjectiveTo assess the association between optical coherence tomography (OCT)-

Myocardial perfusion MRI compared to fractional flow reserve: a meta-analysis [PDF]

open access: yesJournal of Cardiovascular Magnetic Resonance, 2015
Methods This meta-analysis was performed in adherence to the PRISMA statement. Two reviewers systematically searched PubMed, EMBASE and Web of Science, using predefined inclusion and exclusion criteria. Only studies using invasive coronary angiography combined with FFR for assessment of intermediate coronary stenoses were included.

Fractional Flow Reserve or Coronary Flow Reserve for the Assessment of Myocardial Perfusion [PDF]

open access: yesCurrent Cardiology Reports, 2018
Accumulating evidence exists for the value of coronary physiology for clinical decision-making in ischemic heart disease (IHD). The most frequently used pressure-derived index to assess stenosis severity, the fractional flow reserve (FFR), has long been considered the gold standard for this purpose, despite the fact that the FFR assesses solely ...

Stress Myocardial Perfusion Imaging Interpretation From the Viewpoint of Fractional Flow Reserve

open access: yesCirculation Journal, 2021
Myocardial perfusion imaging (MPI) and fractional flow reserve (FFR) are established approaches to the assessment of myocardial ischemia. Recently, various FFR cutoff values were proposed, but the diagnostic accuracy of MPI in identifying positive FFR using various cutoff values is not well established.We retrospectively studied 273 patients who ...

Fractional flow reserve after previous myocardial infarction [PDF]

open access: yesEuropean Heart Journal, 2007
Marques and colleagues have conducted an interesting study on microvascular resistance of viable tissue within an infarcted area. 1 This study is important, not only from a conceptual point of view, but also because it has several relevant implications for the applicability of MIBI spect and fractional flow reserve (FFR) measurement in patients with ...

Comparison between Myocardial Ischemia Evaluation by Fractional Flow Reserve and Myocardial Perfusion Scintigraphy

open access: yesInternational Journal of Cardiovascular Sciences, 2018
Abstract Background: Moderate coronary artery lesions can be, or not, responsible for myocardial ischemia. The functional analysis of these lesions can be performed by invasive and noninvasive methods. Objective: To compare the functional analysis of moderate coronary lesions by fractional flow reserve and myocardial perfusion scintigraphy. Methods: 47
