Myocardial Capillaries and Coronary Flow Reserve

Journal of the American College of Cardiology, 2008
The general assumption among cardiologists is that myocardial ischemia occurs only in the presence of obstructive coronary artery disease. This is based on the misconception that abnormal coronary flow reserve (CFR) is associated only with coronary stenosis and results from the increased ...

Cost-effectiveness of percutaneous coronary intervention in patients with stable coronary artery disease and abnormal fractional flow reserve [PDF]

, 2013
BACKGROUND The Fractional Flow Reserve Versus Angiography for Multivessel Evaluation (FAME) 2 trial demonstrated a significant reduction in subsequent coronary revascularization among patients with stable angina and at least 1 coronary lesion with a ...

Myocardial Perfusion and Coronary Physiology Assessment of Microvascular Dysfunction in Patients Undergoing Transcatheter Aortic Valve Implantation—Rationale and Design

Biomimetics, 2022
The prevalence of coronary artery disease (CAD) in patients with severe aortic stenosis (AS) is 30–68%. Nevertheless, there is still not enough evidence to use invasive assessment of lesion severity, because the hemodynamic milieu of AS may impact the ...

Reduced coronary flow reserve in Anderson-Fabry disease measured by transthoracic Doppler echocardiography

Cardiovascular Ultrasound, 2005
Coronary flow reserve was assessed in a patient with Anderson-Fabry disease complicated by symmetric left ventricular hypertrophy. Coronary flow reserve was measurable in all three major coronary arteries providing an opportunity to compare regional ...

Added Value of Transluminal Attenuation Gradient to Qualitative CCTA Ischemia Detection as Determined by ¹³N-ammonia PET Quantitative Myocardial Perfusion

Diagnostics, 2020
Transluminal attenuation gradient (TAG) represents the slope of intraluminal contrast that decreases along a coronary vessel during coronary computed tomography angiography (CCTA).

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

, 2018
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.

Myocardial perfusion and flow reserve in the asynchronous heart: mechanistic insight from a computational model

, 2023
The tight coupling between myocardial oxygen demand and supply has been recognized for decades, but it remains controversial whether this coupling persists under asynchronous activation, such as during left bundle branch block (LBBB).

Native Coronary Collateral Microcirculation Reserve in Rat Hearts

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background We occasionally noticed that native collateral blood flow showed a recessive trend in the early stages of acute myocardial infarction in rats, which greatly interferes with the accurate assessment of native collateral circulation levels. Here,

Caffeine Decreases Exercise-Induced Myocardial Flow Reserve

Journal of the American College of Cardiology, 2006
We studied the acute effect of caffeine on myocardial blood flow (MBF) at rest and exercise in healthy volunteers at normoxia and during acute exposure to simulated altitude.Caffeine is a widely consumed stimulant, although its cardiovascular safety remains controversial and its effect on MBF is unknown.15O-labeled H2O and positron emission tomography (
