Influence of contrast media dose and osmolality on the diagnostic performance of contrast fractional flow reserve [PDF]

, 2017
Background—Contrast fractional flow reserve (cFFR) is a method for assessing functional significance of coronary stenoses, which is more accurate than resting indices and does not require adenosine.

The Relationship between Coronary Artery Movement Type and Stenosis Severity with Acute Myocardial Infarction [PDF]

Journal of Cardiovascular and Thoracic Research, 2013
Introduction: The severity of coronary artery stenosis which leads to myocardial infarction (MI) has been a matter of controversy. Historical data are in favor of mild luminal stenosis (

Inhibition of in-stent stenosis by oral administration of bindarit in porcine coronary arteries [PDF]

, 2011
<p><b>Objective:</b> We have previously demonstrated that bindarit, a selective inhibitor of monocyte chemotactic proteins (MCPs), is effective in reducing neointimal formation in rodent models of vascular injury by reducing smooth ...

CFD analysis on blood flow inside a symmetric stenosed artery: Physiology of a coronary artery disease

Science Progress, 2023
This research article interprets the computational fluid dynamics analysis on blood flow inside a symmetric stenosed artery. The current problem models the blood flow inside the left coronary artery as having a symmetric stenosis in the central region. A

Deep learning analysis of the myocardium in coronary CT angiography for identification of patients with functionally significant coronary artery stenosis

, 2017
In patients with coronary artery stenoses of intermediate severity, the functional significance needs to be determined. Fractional flow reserve (FFR) measurement, performed during invasive coronary angiography (ICA), is most often used in clinical ...

Computational fluid dynamics modeling of symptomatic intracranial atherosclerosis may predict risk of stroke recurrence. [PDF]

, 2014
BackgroundPatients with symptomatic intracranial atherosclerosis (ICAS) of ≥ 70% luminal stenosis are at high risk of stroke recurrence. We aimed to evaluate the relationships between hemodynamics of ICAS revealed by computational fluid dynamics (CFD ...

Relationship between Coronary Artery Calcium Score and Coronary Stenosis

Cardiology Research and Practice, 2023
Background. The coronary artery calcium score (CACS) is commonly employed to quantify the degree of calcification in coronary atherosclerosis. Indeed, increased coronary stenosis severity is associated with a progressive increase in CACS. Objectives.

Prevalence of carotid artery stenosis in ischaemic heart disease patients in Bangladesh

SAGE Open Medicine, 2019
Background: Concurrent carotid artery stenosis and ischaemic heart disease rates are increasing day by day in Bangladesh. Moreover, carotid artery stenosis has been identified as a high-risk factor for postoperative ischaemic cerebral inconvenience ...
