Abstract Background: Recently, small dense low density lipoprotein (sdLDL) has been highlighted as a new risk factor for the coronary artery disease (CAD).Small dense LDLs are believed to be atherogenic since these particles are taken up more easily by arterial wall. They are readily oxidized and have reduced affinity for low density lipoprotein (LDL) receptor and increased affinity...
OBJECTIVE It is well known that the presence of carotid artery stenosis increases the risk of perioperative stroke in patients undergoing cardiac surgery with cardiopulmonary bypass. Although off-pump coronary artery bypass grafting (CABG) can avoid the adverse effects of cardiopulmonary bypass, the influence of carotid artery stenosis on the incidence of stroke in patients undergoing off-pump ...
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 ...
Background and Purpose—There are limited data on the prognosis of patients with angiographically proved symptomatic stenosis of the intracranial vertebral artery or basilar artery. Methods—We studied 68 patients with 50% to 99% stenosis of one of the following arteries: intracranial vertebral (n531), basilar (n528), posterior cerebral (PCA) (n56), or posterior inferior cerebellar (PICA) (n53). ...
BACKGROUND AND PURPOSE There are limited data on the prognosis of patients with angiographically proved symptomatic stenosis of the intracranial vertebral artery or basilar artery. METHODS We studied 68 patients with 50% to 99% stenosis of one of the following arteries: intracranial vertebral (n = 31), basilar (n = 28), posterior cerebral (PCA) (n = 6), or posterior inferior cerebellar (PICA)...
nary population. This is a very important subject since there are now a lot of cardiologists starting to perform renal artery procedures. There is a unique population of cardiologists that deals with the renal artery stenosis problem. This has been an interest of ours for several years. One of the first studies to examine the prevalence of renal artery stenosis in patients undergoing cardiac ca...
Doppler analysis of flow in intracranial arteries is now possible using a 2 MHz probe allowing sufficient penetration of bone to obtain signals noninvasively. Thirty-two normal subjects, and 11 patients with cerebrovascular diseases including vasospasm following subarachnoid hemorrhage, middle cerebral artery stenosis, and extracranial internal carotid artery stenosis were studied by transcrani...
In the present study, the nonlinear model of non-Newtonian blood flow in cosine-shape stenosed elastic artery is numerically examined. The model is carried out for axisymmetric, two-dimensional and fully developed blood flow. The vessel wall is assumed to be have time-dependent radius that is important factor for study of blood flow. The cosine-shape stenosis convert to rigid artery by using a ...
The aim of this study is to evaluate the changes of effective stress distribution in plaque by progressing to the stenosis throat and to assess the pulsatile pulse pressure effect on effective stress of a viscoelastic finite-element model of carotid arteries having less and more than 50% stenosis. In-vivo geometries of the arteries were reconstructed using consecutive transverse ultrasound imag...
OBJECTIVE It is important to identify patients at risk for atherosclerotic renal artery stenosis because renal artery stenosis is a progressive disease and a potentially correctable problem. This study is to evaluate the prevalence of angiographically-determined renal artery stenosis in a patient population undergoing routine coronary angiography, and to identify the risk factors for renal arte...
