PURPOSE To evaluate the diagnostic performance of left coronary bifurcation angles and plaque characteristics for prediction of coronary stenosis by dual-source CT. METHODS 106 patients suspected of coronary artery disease undergoing both coronary computed tomography angiography (CCTA) and invasive coronary angiography (CAG) within three months were included. Left coronary bifurcation angles ...

The aim of the present study was to investigate the correlation between the degree of coronary artery stenosis determined by digital subtraction angiography (DSA) and infarcted segments detected by delayed enhancement magnetic resonance imaging (DE-MRI). DE-MRI and DSA were performed in 40 patients with coronary artery disease. The number of myocardial segments with infarction, the transmural e...

conclusions according to the results, there were no significant and meaningful differences comparing acs and csa groups of patients by ecds using three indicators of stenosis, plaque morphology and imt as indicators of atherosclerosis. results also display that patients with acs had more stenosis, more plaque and thicker intima–media, but these differences were not statistically significant (p ...

Introduction : Significant left main coronary artery stenosis jeopardizes the entire myocardium of the left ventricle and has the worst prognosis of any form of coronary artery disease. Coronary-artery bypass grafting (CABG) has been considered as the standard therapeutic approach for such patients. There are limited data on the safety and effectiveness of percutaneous coronary intervention (PC...

English Bulldogs are the most common breed to have pulmonic stenosis. Previous studies showed that this congenital heart abnormality in Bulldogs frequently is caused by a circumpulmonary left coronary artery originating from a single right coronary artery. Fetal anasarca also occurs often in Bulldogs and might represent congestive heart failure, but the cause is unknown. To determine if fetal a...

OBJECTIVE Coronary artery disease is closely linked with inflammation, and the neutrophil-to-lymphocyte ratio (NLR) has emerged as a new inflammatory marker. Fractional flow reserve (FFR) is a well-established method for determining hemodynamic significance of coronary artery stenosis. In this study, we aimed to investigate the relationship between NLR and hemodynamic significance of coronary a...

BACKGROUND Coronary artery disease (CAD) is associated with the numbers of risk factors causing coronary atherosclerosis. Coronary artery stenosis is mostly caused by coronary atherosclerosis. OBJECTIVE This study aims to analyze the association between coronary artery stenosis and cardiovascular risk factors. METHODS An observational study was conducted among CAD patients. The diagnostic c...

BACKGROUND AND PURPOSE Identifying occult coronary artery stenosis may improve secondary prevention of stroke patients. The aim of this study was to derive and validate a simple score to predict severe occult coronary artery stenosis in stroke patients. METHODS We derived a score from a French hospital-based cohort of consecutive patients (n=300) who had an ischemic stroke or a transient isch...

Background: Pulse pressure has recently been considered as a predictor of coronary heart disease. The difference between systolic and diastolic blood pressure is called pulse pressure. Various factors including increased age, vascular stiffness, stenosis, and hypertension are associated with pulse pressure. The present study, therefore, aimed to investigate the relationship between some cardiov...
