Filter by:The IRISS study is designed to collect clinical and angiographic outcomes data when stenting intracranial atherosclerotic lesions using the Wingspan™ Stent System with Gateway™ PTA Balloon Catheter in routine clinical practice.
Early Identification of Subclinical Atherosclerosis by Noninvasive Imaging Research (EISNER) is a multi-study research program being conducted at Cedars-Sinai Medical Center. The principal objective of this randomized trial (referred to as "Study 1") is to assess whether coronary artery calcium (CAC) scanning provides clinical benefit thus improving patient outcomes in asymptomatic subjects with intermediate coronary artery disease (CAD) risk. Additionally, the study is designed to assess the value of combining the CAC scan with the Framingham risk score (FRS) and measurements of serum or plasma biomarkers to predict outcomes.
18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) is a promising tool for identifying and quantifying vascular inflammation within atherosclerotic plaques. Therefore, in this study the investigators intend to compare the effect of ezetimibe monotherapy or ezetimibe plus statin combination therapy on the atherosclerosis regression using FDG-PET.
HIV infection is associated with systemic inflammation that is involved in pathogenesis of atherosclerosis. Treatment of HIV infection may cause lipid profile disturbance and consequently, atherosclerosis progression. In general, extra virgin olive oil (EVOO) has beneficial effect on atherosclerosis markers. Our goals are to examine the effect of EVOO on atherosclerosis markers in HIV-treated patients. A controlled randomized cross-over study will be performed on 40 participants. They will consume EVOO and ROO (refined olive oil) during two 20 days intervention periods, interrupted with 14 days wash-out period. Before the trial and after both intervention periods we will analyze participants' blood for: ESR, white blood cell count, hsCRP, interleukin-6, oxidized LDL, glutathione peroxidase, superoxide dismutase, malondialdehyde, triglycerides, total cholesterol, HDL and LDL cholesterol, fibrinogen, factor VII and von Willebrand factor. We expect an improvement of these parameters after three weeks of EVOO consumption.
Coronary artery disease (CAD) is an important health concern for African Americans, who are diagnosed with CAD at high rates. Coronary artery calcification, which is characterized by calcium deposits in the coronary arteries, is a contributing factor to CAD. This study will examine the possible genetic causes of coronary artery calcification in African Americans.
The aim of this cross-sectional study is to determine the correlation of coronary artery calcification as measured by electron-beam computerized tomography and coronary flow reserve measured by trans-thoracic Doppler echocardiography in hemodialysis patients. The investigators also assessed the carotid artery parameters by measuring intima media thickness that can accurately describe the process of arterial wall changes due to atherosclerosis. Possible association of coronary flow reserve with inflammation and arterial calcification in hemodialysis patients was also evaluated.
The study hypothesis (or theory) is that monthly loss of iron before menopause may reduce women's risk of hardening of the arteries, or atherosclerosis. This study uses noninvasive, noncontrast magnetic resonance imaging (MRI) of arteries in women entering menopause. This will help to determine if there is a correlation between iron accumulation and hardening of the arteries. In addition, blood levels of hormones will be measured to help show differences due to hormone levels vs. iron accumulation.
The purpose of this study is to determine whether HMG-CoA reductase inhibitor, atorvastatin attenuates inflammation in atherosclerotic plaques detected by 18F-fluorodeoxyglucose(FDG) PET.
20 patients will be recruited. The aim of the study is to determine the natural progression of atherosclerotic disease.
The specific aim of the SOS-Xience V study is to examine the 12-month incidence of binary angiographic in-stent restenosis after implantation of the Xience V stent in aortocoronary saphenous vein bypass graft lesions.
