117338, 2023 Coronary Artery Disease (CAD) is one of the most common forms of heart disease, which is caused by a buildup of atherosclerotic plaque (known as stenosis) in the coronary arteries, leading to insufficient supplement of blood, oxygen, and nutrients to the heart.

Effect of Varying Hemodynamic and Vascular Conditions on Fractional Flow Reserve: An In Vitro Study
Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016 BackgroundThe aim of this study was to investigate the impact of varying hemodynamic conditions on fractional flow reserve (ratio of pressure distal [Pd] and proximal [Pa] to stenosis under hyperemia) in an in vitro setting.

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