Fractional Flow Reserve–Guided Multivessel Angioplasty in Myocardial Infarction [PDF]

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

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

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

Association Among Noncalcified Coronary Burden, Fractional Flow Reserve, and Myocardial Injury in Psoriasis

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Myocardial infarction and premature death have been observed in patients with psoriasis. Although inflammation‐driven accelerated atherosclerosis has been proposed as a mechanism, the relationship between subclinical noncalcified coronary ...

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

Circulation, 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.

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

International 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

Validation of Collateral Fractional Flow Reserve by Myocardial Perfusion Imaging [PDF]

Circulation, 2002
Background — Collateral fractional flow reserve (FFR coll ) is an index to quantify collateral blood flow, derived from coronary pressure measurements.

Personalised fractional flow reserve: a novel concept to optimise myocardial revascularisation

EuroIntervention, 2019
Fractional flow reserve (FFR) represents the percentage reduction in coronary flow relative to a hypothetically normal artery; however, percutaneous coronary intervention (PCI) seldom achieves physiological normality (FFR 1.00), particularly in the context of diffuse disease.

Fractional flow reserve after previous myocardial infarction [PDF]

European 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 ...

Differential stress-induced ischemic electrocardiographic changes in acute versus stable coronary syndromes with severely reduced fractional flow reserve (≤0.60) [PDF]

International Journal of Cardiology: Heart & Vasculature
Background: Fractional flow reserve (FFR) is widely used to guide percutaneous coronary intervention (PCI) as a surrogate of inducible myocardial ischemia (IMI).

Fractional Flow Reserve-Based Patient Risk Classification

Diagnostics, 2023
Cardiovascular diseases (CVDs) are a leading cause of death. If not treated in a timely manner, cardiovascular diseases can cause a plethora of major life complications that can include disability and a loss of the ability to work.
