abstract

endothelial dysfunction and carotid intima-media thickness are 2 indicators of subclinical cardiovascular disease. the aim of study was to analyze brachial flow mediated dilation(fmd)and carotid intima media thickness (cimt)in patients with coronary artery disease, and investigate the relationship between endothelial function, cimt and coronary artery disease risk factors.56 men and women aged between 25 to 75 years with coronary artery disease were recruited. fmd and cimt was measured by b-mode ultrasonography. data were presented  as  mean  ±  se.  pearson correlation  coefficients  were  used  to  evaluate associations   and  t-test  and  chi-square  tests  were  used  for  quantitative  and qualitative variables. p -values  <  0.05  were considered  to  indicate  statistically  significant  differences. the mean age of subjects was 59.37±1.28 years. the frequencies of one, two and three-vessel coronary artery disease were 61%, 35.1% and 3.9%, respectively. the mean of cimt in patients was 0.79±0.02 mm, and 65.5% of patients had cimt more than 0.8 mm.the mean of fmd was 4.79±0.55% and 65.4% of patients had fmd lower than 5.3%. cimt was correlated directly with number of diseased vessels, age andtotal cholesterol and was correlated inversely with hdl-c.non-invasive measurement of fmd and cimt are interrelated techniques that probably assess the same atherosclerotic process from functional and anatomic viewpoints.in these patients an increase in cimt and decrease in fmd may warrant more aggressive risk factor control through the beginning of effective medical treatment.

mean right and left carotid intima-media thickness measures in cases with/without coronary artery disease.

one of the important factors which should be considered in (coronary artery disease) cad cases is increased carotid intima-media thickness (imt) which has been considered to be associated with coronary artery disease severity and cardiovascular events. the goal of this study was to compare risk factors and carotid imt in cases with cad and healthy subjects and to determine the association betwe...

Carotid artery Intima-Media thickness and cardiovascular risk factors in chronic hemodialysis patients

Introduction: Common carotid artery intima-media thickness (CCA-IMT) correlates with cardiovascular mortality in patients under hemodialysis. In this investigation, we evaluated relationship between CCA-IMT with dependent and independent cardiovascular risk factors in chronic hemodialysis patients. Methods: In this cross-sectional study, 51 chronic hemodialysis patients, (31 males and 20 fema...

The Assosiation of Carotid Intima-Media Thickness and Ankle Brachial Index with SPECT Myocardial Perfusion Imaging in Asymptomatic Diabetic Patients

Objective: The risk of cardiac death in diabetic patients is 3 times more than non-diabetics. But it is not determined who need cardiac screening. About 41% of diabetic patients with silent ischemia are missed. the carotid intima-media thickness (CIMT) and ankel brachial index are two independent,simple and non invasive method in vascular complications diagnosis in diabetic patients.The aim of ...

Coronary artery disease and carotid artery intima-media thickness in Japanese type 2 diabetic patients.

OBJECTIVE To investigate the association between carotid atherosclerosis, measured as intima-media thickness (IMT), and cardiovascular morbidity in type 2 diabetic patients. RESEARCH DESIGN AND METHODS We investigated the relationship between IMT and coronary artery disease (CAD) in 40 type 2 diabetic patients and 40 control subjects. Diabetic patients with CAD determined by coronary angiogra...

Association between Plasma Homocysteine Concentrations and Carotid Intima-Media Thickness in Patients with Coronary Artery Disease

Introduction: Although homocysteine has atherogenic and prothrombotic properties, the conflicting results from studies made its role in coronary artery disease unclear. Objectives: The aim of this study was to evaluate the association between plasma levels of homocysteine and carotid atherosclerosis in patients with angiographically confirmed coronary artery disease. Methods: This prospective s...

BACKGROUND The aim of this study was to assess the relationship between brachial artery flow mediated dilation (FMD), carotid artery intima-media thickness (IMT) and coronary flow reserve (CFR) in patients with coronary artery disease (CAD). METHODS Fifty patients with coronary artery disease, except left anterior descending artery (LAD), who showed no cardiac symptoms and 45 control subjects...
