Lesion Eccentricity and Fractional Flow Reserve and Coronary Flow Reserve in Coronary Arteries

2013
Fractional flow reserve has shown to be a gold standard in assessment of functional significance of coronary artery stenosis. Lesion eccentricity is an important geometric parameter which may affect the translational hemodynamics. Three dimensional quantitative coronary angiography (3D-QCA) was used to reconstruct the proximal or mid left anterior ...

Coronary flow reserve is reduced in sarcoidosis

Atherosclerosis, 2017
Sarcoidosis is a multisystem disease with frequent cardiac involvement, albeit manifest cardiac disease is rare. Though epicardial coronary arteries are not frequently involved, microvascular disease is rather common in both symptomatic and asymptomatic patients. The mechanism of microvascular involvement has not been elaborated yet.

Coronary Blood Flow and Coronary Vascular Reserve

1989
The severity of coronary artery disease (CAD) has traditionally been evaluated by assessing coronary artery anatomy and left ventricular function during cardiac catheterization. The reduction in coronary artery blood flow caused by a particular stenosis has been inferred from its appearance on coronary arteriography.1 It is now well known that the ...

Experimental hyperhomocysteinemia impairs coronary flow velocity reserve

International Journal of Cardiology, 2005
Hyperhomocysteinemia has been identified as an independent risk factor for coronary artery disease. One mechanism is considered to be deteriorated endothelial function that is recovered by vitamin C. However, its direct action on coronary circulation has yet to be examined.

Coronary Flow Resistance and Reserve

2015
The coronary arteries are the initial vessels off of the aorta and eventually end in a rich capillary bed that provides blood to the myocytes in a one to one fashion (one capillary for each myocyte.) The myocardial oxygen concentration is at maximum such that any increase in myocardial blood flow (MBF) can only be accomplished by increase in coronary ...

Stimuli Testing Coronary Flow Reserve

2002
A wide panel of stimuli can be used to induce changes in coronary blood flow. Generally the stimuli can be divided into those decreasing (NO synthase inhibitors) or increasing coronary blood flow via EDV or EIDV. The former stimuli induce transient endothelial dysfunction in the normal coronary circulation.
