Active clinical trials for "Atherosclerosis"

To determine if there is an association between Porphyromonas gingivalis infection of dental gingiva during primary tooth eruption and thickening of the radial artery intimamedial layers. Thickening of these layers in infants could be a promoting factor for later development of atherosclerosis.

This is a multi-center, investigator initiated study that will prospectively examine treatment strategies and outcomes of patients who underwent clinically-indicated Near Infrared Spectroscopy (NIRS). The information collected will be used to determine the frequency of NIRS imaging performed at the participating sites and to examine the clinical outcomes of the NIRS-detected Lipid Core Plaques (LCPs).

It is the investigators aim to determine the feasibility of directly detecting anti-RLIP76 auto-antibodies in human serum using prepared RLIP76 antigen peptides in persons with rheumatologic disease and persons without rheumatologic diesease ("healthy subjects").

Our study aims to evaluate endothelial function using the non-invasive EndoPAT device, and compare this assessment to traditional cardiovascular risk calculation tools and carotid intima media thickness measurements. We look to determine whether the discovery of endothelial dysfunction provides incremental risk stratification over traditional and CIMT methods of cardiovascular risk assessment.

This study is a non-randomized prospective cohort study that will define the rate of index atherosclerotic plaque development in adults with a prior coronary artery calcium (CAC) score of 0 given prior CAC zero > 5 years previous. Ancillary testing of serum, whole blood, and endothelial dysfunction will be performed to investigate any detectable systemic processes that predict CAC development.

This study will use excess tissue from endoscopic or surgical procedures to examine the elements of plaque that are found in the carotid walls of patients who have a type of heart and blood vessel disease called atherosclerosis. Tissue will be collected from patients undergoing carotid procedures as well as patients undergoing liver and/or intestinal biopsies. This lab study will examine the different types of proteins that play a role in developing heart plaque.

In this proposal, the investigators will demonstrate the feasibility and noninferiority of telerobotic ultrasonography as compared to traditional manual acquisition in performing a limited carotid Duplex examination and in carotid plaque detection.

The current study is designed to test the hypothesis that compared to conventional treatment; endothelial function-guided treatment reduces adverse cardiovascular events in patients with non-obstructive coronary artery disease documented at clinically indicated coronary angiography.

The primary objective of this study is to characterize coronary artery blockages as determined by the LipiScan combined NIRS-IVUS catheter using multi-vessel imaging.

Study to assess changes in carotid and aortic atherosclerosis in patients being treated with lomitapide.
