Fractional Flow Reserve–Guided Multivessel Angioplasty in Myocardial Infarction

New 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

Functional Assessment of Myocardial Bridging With Conventional and Diastolic Fractional Flow Reserve: Vasodilator Versus Inotropic Provocation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Functional assessment of myocardial bridging (MB) remains clinically challenging because of the dynamic nature of the extravascular coronary compression with a certain degree of intraluminal coronary reduction.

Effect of Plaque Burden and Morphology on Myocardial Blood Flow and Fractional Flow Reserve

Journal of the American College of Cardiology, 2018
Atherosclerotic plaque characteristics may affect downstream myocardial perfusion, as well as coronary lesion severity.This study sought to evaluate the association between quantitative plaque burden and plaque morphology obtained using coronary computed tomography angiography (CTA) and quantitative myocardial perfusion obtained using [15O]H2O positron

Fractional Flow Reserve-Negative High-Risk Plaques and Clinical Outcomes After Myocardial Infarction.

JAMA cardiology, 2023
Importance Even after fractional flow reserve (FFR)-guided complete revascularization, patients with myocardial infarction (MI) have high rates of recurrent major adverse cardiovascular events (MACE).

Machine Learning From Quantitative Coronary Computed Tomography Angiography Predicts Fractional Flow Reserve–Defined Ischemia and Impaired Myocardial Blood Flow

Circulation Cardiovascular Imaging, 2022
Background: A pathophysiological interplay exists between plaque morphology and coronary physiology. Machine learning (ML) is increasingly being applied to coronary computed tomography angiography (CCTA) for cardiovascular risk stratification.

Regional Myocardial Work Measured by Echocardiography for the Detection of Myocardial Ischemic Segments: A Comparative Study With Invasive Fractional Flow Reserve

Frontiers in Cardiovascular Medicine, 2022
Purpose This study is to assess the diagnostic value of noninvasive regional myocardial work (MW) by echocardiography for detecting the functional status of coronary stenosis using fractional flow reserve (FFR) as a standard criterion. Methods A total of

Economic evaluation of fractional flow reserve-guided versus angiography-guided multivessel revascularisation in ST-segment elevation myocardial infarction patients in the FLOWER-MI randomised trial.

EuroIntervention, 2022
BACKGROUND In patients with ST-segment elevation myocardial infarction (STEMI) who have multivessel disease, the FLOWER-MI trial found no significant clinical benefit to fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI ...

Lesion-Specific Peri-Coronary Fat Attenuation Index Is Associated With Functional Myocardial Ischemia Defined by Abnormal Fractional Flow Reserve

Frontiers in Cardiovascular Medicine, 2021
Background: The association between abnormal invasive fractional flow reserve (FFR) and the fat attenuation index (FAI) of lesion-specific peri-coronary adipose tissue (PCAT) is unclear. Method: Data of patients who underwent coronary computed tomography
