Filter by:The purpose of this study is to determine if bempedoic acid (ETC-1002) added-on to ezetimibe therapy is effective and safe versus placebo in patients with elevated LDL cholesterol.
Polyphenol supplements, including curcumin and resveratrol, are known to decrease inflammation, but previous polyphenol supplements were poorly absorbed and thus their effects were reduced. A new phytosome formulation coats the supplements and allows them to be better absorbed. The purpose of this study is to examine the acute (1-hr) and short-term (1-week) effects of two different phytosome-formulated polyphenol supplements on inflammation. The two supplements that will be used are: 1) PolyResveratrol and 2) Curcumin.
Stroke and abdominal aortic aneurysms (AAAs) are common and highly lethal vascular diseases. Angiogenesis and infiltration of inflammatory cells such as macrophages may cause stroke and AAAs. The purpose of this study is to test PET/CT and PET/MRI imaging to specifically detect those diseases using a new developed agent (18F-FPPRGD2) that can target angiogenesis and macrophages.
Aim 1: To determine whether therapy with Alirocumab, compared to pre-treatment, will effectively improve carotid atherosclerotic plaque characteristics by reducing Ktrans and LRNC size. To achieve this goal, we will (a) enroll 30 subjects who are intolerant to high intensity statin therapy and only able to tolerate low potency statin or low weekly dose of high potency statin and have LDL-C ≥70 mg/dl; (b) initiate alirocumab at 150mg subcutaneously injection every 2 weeks; (c) perform carotid DCE-MRI scans at baseline, 3, 6 and 12 months; (d) perform quantitative analysis for vascular inflammation and plaque LRNC volume and other plaque characteristics; (e) compare vascular inflammation and LRNC volume between pre- and post-alirocumab at 3, 6 and 12 months. Aim 2: To examine associations between reductions in atherogenic lipids (LDL-C, Lp(a), non-HDL-C) and changes in atherosclerotic plaque characteristics. To achieve this goal, we will (a) perform laboratory assessments of lipids, lipoproteins and apo-lipoproteins at baseline and during the study; (b) compare lipids, lipoproteins and apo-lipoproteins levels between pre- and post-alirocumab; (c) correlate reductions in atherogenic lipids with changes atherosclerotic plaque characteristics.
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 purpose of this study is to see if bemedoic acid (ETC-1002) is effective versus placebo in patients with high cardiovascular risk and elevated LDL cholesterol not adequately controlled by their current therapy.
Ultraviolet (UV) phototherapy is a standard treatment for many inflammatory dermatological diseases, including psoriasis. The systemic effects of UV phototherapy are still not well studied. There are several factors that may affect patient's cardiovascular (CV) risk during UV phototherapy. Atherosclerosis is now known to have an inflammatory origin and to be frequently associated with psoriasis. In this study the investigators aim at studying the effect of psoralen-UVA phototherapy on several biomarkers of CV risk in patients with psoriasis with or without atherosclerosis.
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.
The purpose of this study is to determine if bempedoic acid (ETC-1002) is effective and safe versus placebo in patients with elevated LDL cholesterol and who are statin-intolerant.
Determine the relationship between the systemic indications of atherosclerosis by means of the change in the ratio of periodontopathogenic microorganisms following periodontal treatment of individuals who have been diagnosed with chronic periodontitis-atherosclerosis and for individuals who have been diagnosed with systemically healthy-chronic periodontitis.
