Active clinical trials for "Atherosclerosis"

Vascular inflammation, a central feature of atherosclerosis, participates in the initiation, perpetuation and instability of plaques. Multiple clinical trials of cholesterol lowering therapy with statins have demonstrated that reductions in atherosclerotic cardiovascular disease (CVD) events are associated with reductions in both LDL cholesterol (LDL-C) and the systemic inflammatory mediator C-reactive protein (CRP). The Cardiovascular Inflammation Reduction Trial (CIRT) investigates if an anti-inflammatory agent commonly used in rheumatoid arthritis (low dose methotrexate (LDM)) can reduce CV morbidity and mortality among patients with a prior myocardial infarction or angiographically demonstrated multivessel coronary artery disease (GCO#13-1467). In this ancillary CIRT imaging study, the investigators propose to use this well validated approach by non-invasive serial FDG-PET/CT imaging in a subset of patients enrolled in the main CIRT trial to directly visualize vascular inflammation. Once the subjects are enrolled in the main CIRT trial, baseline imaging will be done and follow up imaging will be done approximately 8 months after the baseline imaging. 18FDG-PET imaging data will be acquired, analyzed centrally and results incorporated into the main CIRT database. The investigators hypothesize that LDM treatment will result in a significant decrease in plaque inflammation as measured by 18-FDG-PET/CT after 8 months as compared to placebo.

A prospective, open label, controlled, randomized, double arm, multi-center study to assess the efficacy and safety of CLBS12 in patients with critical limb ischemia (CLI) due to arteriosclerosis obliterans (ASO) with a single arm sub-study to assess the safety and potential efficacy of CLBS12 in patients with CLI due to Buerger's Disease (BD).

The primary objective of this study is to evaluate the success of lesion preparation with either rotational atherectomy or cutting/scoring balloons as well as the long term effects of a hybrid sirolimus-eluting stent in an angiographically well-defined group of patients with complex calcified coronary lesions.

This will be a double-blind randomized clinical trial carried out on subjects with suboptimal control of LDL-cholesterolemia, following a Mediterranean diet, and treated with a red yeast rice extract (containing 10 mg monacolin K per daily dose) or placebo, in order to evaluate the middle-term effects on vascular health evaluated by non invasive methods (Vicorder(R) apparatus)

Peripheral artery disease (PAD) is the third most prevalent cardiovascular disease worldwide, with over 200 million people affected. Most prominent symptom is leg pain while walking known as intermittent claudication. Based on the currently existing gaps in the management of intermittent claudication, the objective of the this study is to explore the clinical effectiveness and cost advantage of TeGeCoach, a 12-month long home-based exercise program, compared to usual care. TeGeCoach consists of telephone health coaching, remote walking exercise monitoring based on wearable activity monitors and intensified primary care. It is hypothesized that TeGeCoach will improve functional outcomes and will reduce total health care costs.

The effects of a nutraceutical combination (NC) containing low-dose monacolin K and berberine on lipid profile, proprotein convertase subtilisin/kexin type 9 (PCSK9), subclinical inflammation and arterial stiffness were investigated in human immunodeficiency virus (HIV)-infected patients receiving stable antiretroviral therapy (ART).

The purpose of this trial is to evaluate the safety and efficacy of sonodynamic therapy (SDT) on reducing atherosclerotic plaques inflammation among patients with symptomatic femoropopliteal peripheral artery disease.

The purpose of this study is to look at the effects of the drug Ranolazine compared to Placebo on symptoms of chest pain or chest tightness (known as angina), exercise endurance and ability, and changes in blood flow to the very small arteries of the heart (known as coronary microvascular function) in patients who do not have significant blockages in their major heart arteries. Ranolazine is a drug that is already approved by the FDA for angina, but it may be particularly effective in people with disease in their tiny heart vessels (known as coronary microvascular disease). This trial aims to enroll 50 patients with angina who undergo baseline bicycle exercise testing with monitoring of the heart's electrical activity and oxygen consumption (known as cardiopulmonary exercise test) and coronary angiogram (taking pictures of the heart arteries through small hollow tubes placed through the wrist or groin). If severe blockages in the main arteries are not found then testing for coronary microvascular function will be performed. Subsequently, participants will then be randomized 50/50 to either Ranolazine or Placebo. After taking the study drug for 12 weeks, they will then repeat the cardiopulmonary exercise test and the coronary angiogram with testing for microvascular function.

The aim of the present study was to evaluate the effect of pre-procedural single high loading dose (40 mg) of rosuvastatin on the primary end-points of all cause mortality and composite of death or myocardial infarction from cardiovascular (CV) causes, target vessel revascularization (TVR), or stroke.

Administration of vitamin D will have a beneficial effect on postprandial leukocyte activation, oxidative stress and arterial stiffness in vitamin D deficient females. High doses of vitamin D may have a more pronounced effect than low doses.
