Active clinical trials for "Atherosclerosis"

To evaluate the relation of retinal microvascular characteristics to subclinical cardiovascular disease, clinical disease, and their risk factors in the Multi-Ethnic Study of Atherosclerosis (MESA) cohort.

The Learning Registry is a retrospective, exempt study. Researchers form the Duke Clinical Research Institute (DCRI) will utilize de-identified data managed by Cerner for population health analytics as part of a ongoing registry of patients with atherosclerotic cardiovascular disease. Cerner is an electronic health record company utilized by a large number of health systems in the United States. As part of their services to the health systems that they work with, they have created platform for population health management called HealtheIntent. HealtheIntent uses individual data from patients at a health system collected through the EMR as well as other data streams in the health system (i.e. cost data), aggregates the data, and stores it on an Amazon Web Services cloud, accessible to both Cerner and the health systems, to perform large scale population health analytics. These data may be linked as well by Cerner to the National Death Index or other data sources depending on the individual relationship with the sites. For this retrospective study, the Study Start Date is the date contracts were executed; Primary Completion Date is the date the final dataset is available for analysis and manuscript development; Study Completion Date is the date the study is completed. Enrollment is the number of patient charts reviewed.

Epistaxis is a very frequent emergency among adults and often needs specialised treatment in an ENT-department. Among others, atherosclerosis is often named as a reason for an increased risk for Epistaxis. To evaluate whether or not this is the case, the investigators examined the carotid intima media thickness via ultrasound in patients who were treated in the ENT-department of the University Hospital of Zurich.

Accelerated atherosclerosis in patients with systemic lupus erythematosus (SLE) is not fully explained by Framingham risk factors. The detection in asymptomatic patients of somatic mutations in genes involved in hematopoietic malignancy- defining clonal hematopoiesis of indeterminate potential (CHIP) - predisposes to cardiovascular events (CVE) in general population. We aimed to determine whether CHIP is associated with CVE in SLE.

Title: Combined Optical Coherence Tomography Morphologic and Fractional Flow Reserve Hemodynamic Assessment of Non-Culprit Lesions to Better Predict Adverse Event Outcomes in Diabetes Mellitus Patients COMBINE (OCT-FFR) Prospective Register To study the natural evolution of patients with at least one intermediate angiographic but non-hemodynamic significant stenotic lesion, in two subgroups of patients, with TCFA vs. no TCFA as detected by OCT imaging and to compare these two groups of patients with each other as well as to a subset of patients with FFR-positive and PCI-treated intermediate lesions on future MACE.

Arterial stiffness is an important marker of cardiovascular risk. It is measured by pulse wave velocity. The reference device to measure pulse wave velocity is the Sphygmocor which uses applanation tonometry. It is used in adults and children. An easier method called pOpmètre using saturation sensors is validated in adults but not in children. The objective of this study is to compare the pulse wave velocity values measured with the pOpmètre® with those of the SphygmoCor® to validate the pOpmètre in children between 4 and 8 years old.

The CONFIRM study was developed to examine the prognostic value of cardiac computed tomographic angiography (CCTA) findings for prediction of future adverse cardiac events related to coronary artery disease (CAD) in a large, international patient population. The purpose of this multicenter registry is to correlate coronary and non-coronary cardiac findings by CCTA with demographic and clinical data for refinement of risk stratification of individuals with suspected or known CAD.

This trial is to assess physician-determined XIENCE V® EECSS acute performance, deliverability and resource utilization in the catheterization lab during commercial use by various physicians with a range of coronary stenting experience

This is an observational study to measure the thickness of artery walls in the neck (intima media thickness IMT) by ultrasound examination in middle-aged subjects with central obesity. The purpose of this study is to obtain local data how common asymptomatic atherosclerosis is, and to investigate the association between Cardiovascular Disease risk factors and intima media thickness (IMT) in the Hong Kong population. Results from this study may enhance the public awareness of asymptomatic atherosclerosis and understand its role in the development of Cardiovascular Disease in Hong Kong.

This study is designed to evaluate the technical performance and clinical handling of a coronary catheter that includes two imaging techniques. The catheter being evaluated performs near infrared spectroscopy and ultrasound imaging of the coronary arteries. Near infrared spectroscopy is used to identify lipid or cholesterol deposits in the vessel wall and the ultrasound component provides structural information about the vessel. Combining multiple imaging techniques into a single catheter can reduce the total number of catheters required during treatment and the overall duration of cardiac catheterization. Both of these results may lead to safer procedures.
