Three-Dimensional Angiographic Characteristics versus Functional Stenosis Severity in Fractional and Coronary Flow Reserve Discordance: A DEFINE FLOW Sub Study

Diagnostics, 2022
Background: Coronary angiography alone is insufficient to identify lesions associated with myocardial ischemia that may benefit from revascularization.

Coronary flow reserve by CT perfusion [PDF]

Journal of Nuclear Cardiology, 2010
Cardiovascular computed tomography (CT) is one of the most impressive advances in the non-invasive diagnosis of cardiovascular disease in the last decade. Going beyond coronary calcium scoring, cardiovascular CT is capable of identifying calcified and non-calcified plaque, percent stenosis, cardiac structure and morphology, and left ventricular ...

Coronary Flow Capacity to Identify Stenosis Associated With Coronary Flow Improvement After Revascularization: A Combined Analysis From DEFINE FLOW and IDEAL

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Coronary flow capacity (CFC), which is a categorical assessment based on the combination of hyperemic coronary flow and coronary flow reserve (CFR), has been introduced as a comprehensive assessment of the coronary circulation to overcome the ...

Invasive physiological indices to determine the functional significance of coronary stenosis

International Journal of Cardiology: Heart & Vasculature, 2018
Physiological measurements are now commonly used to assess coronary lesions in the cardiac catheterisation laboratory, and this practice is evidence-based and supported by clinical guidelines. Fractional flow reserve is currently the gold standard method

Clinical significance of PET-CT coronary flow reserve in diagnosis of non-obstructive coronary artery disease

BMC Research Notes, 2018
Objective To improve current knowledge of coronary flow reserve and non-obstructive coronary artery disease in terms of definition, features and clinical implications of measurement of coronary flow reserve (CFR), is an integrated measure of focal ...

Endothelial and non-endothelial coronary blood flow reserve and left ventricular dysfunction in systemic hypertension

Clinics, 2009
OBJECTIVES: We evaluated the impairment of endothelium-dependent and endothelium-independent coronary blood flow reserve after administration of intracoronary acetylcholine and adenosine, and its association with hypertensive cardiac disease ...

Effects of Atorvastatin on Coronary Flow Reserve in Patients with Slow Coronary Flow [PDF]

Clinical Cardiology, 2007
AbstractBackgroundStatins improve endothelial functioning in patients with coronary artery disease and hypercholesterolemia, while substantially little is known about induced changes in myocardial microcirculation. However, although previous studies have suggested that microvascular abnormalities and endothelial dysfunction is responsible for slow ...

Bimodal Pattern of Coronary Microvascular Involvement in Diabetes Mellitus

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundThe contribution of functionally disturbed coronary autoregulation and structurally impaired microvascular vasodilatory function to reduced coronary flow velocity reserve, reflecting impaired coronary microcirculation in diabetes mellitus (DM),

Modern scintigraphic methods for assessing myocardial blood flow and reserve

Бюллетень сибирской медицины, 2021
Background. Today, myocardial perfusion scintigraphy is an informative and accessible method for evaluating ischemic changes in the heart. However, this method has limitations, which are more connected with a semiquantitative assessment of the study ...
