Active clinical trials for "Arteriosclerosis"

Concomitant AF ablation with HIFU in patients with persistent or long standing persistent AF undergoing CABG will be superior in restoring SR, compared with patients with persistent or long standing persistent AF undergoing CABG treated with best medical treatment according to ACC/AHA/ESC 2006 guidelines and no AF ablation.

The REPLICA TRIAL tries to assess the intracoronary lithotripsy safety and efficacy profiles in real-world patients with calcified coronary artery disease.

To compare in a prospective randomised way the effect of two different immunosuppressive regimens - mTOR-based regimen or CNI-based regimen - on the progression of coronary artery calcification in renal transplant patients measured at baseline, 1, 2, and 3 years after transplantation.

The aim of this trial is to evaluate the efficacy and safety of telmisartan 80 mg administered once daily in patients with documented coronary artery disease (CAD) and a probably cardiovascular risk profile concerning the amelioration of structural alterations and endothelial function. The primary objective of this trial is to evaluate the efficacy in particular with regard to the percentage change of atheroma volume in the femoral artery.The secondary objective is to evaluate the change in the plaque size- assessed by intravascular ultrasound, the increase in Flow Dependent Dilation provoked by intraarterial infusion of three increasing concentrations of Acetylcholine, and the change in seated systolic blood pressure. Endothelial dysfunction is a primary event in atherogenesis and all known cardiovascular risk factors have been associated with endothelial dysfunction before atherosclerotic vascular disease manifests itself clinically. Pivotal to endothelial dysfunction is a disturbance in the function of endothelium-derived nitric oxide (NO). Recently, it could be shown that acute and chronic angiotensin-1 receptor antagonism reversed endothelial dysfunction in atherosclerosis. In experimental atherosclerosis, AT1 receptor blockade appears to have protective effects. Respective potential mechanisms include the prevention of endothelial injury, the augmentation of NO activity, the inhibition of lipid peroxidation and an antiproliferative effect. These findings together with the most recent data that losartan improves endothelial function and NO activity suggest that AT1 receptor antagonism may also be antiatherogenic in patients with atherosclerosis. Angiotensin II influences smooth muscle cell migration, hyperplasia, and hypertrophy. Angiotensin II also enhances production of local superoxide anion, which will inactivate nitric oxide. Inhibition of these reactions by the AT1-Blocker telmisartan may therefore interfere with atherosclerotic plaque formation.

The study tests if intense light could be a potential therapy in humans after myocardial infarction by inducing Per2.

The purpose of this study is to compare standard therapy (risk factor control, life style modification) versus standard therapy plus low-dose rosuvastatin therapy (5mg/day) on progression of coronary atherosclerosis in statin naive individuals who have mild CAD (nonobstructive coronary atherosclerotic plaques) and normal LDL (low-density lipoprotein) cholesterol levels(<130mg/dl).

Objectives: Primary: To evaluate the effect of rimonabant 20-mg once daily in comparison with placebo, on the quantitative progression of atherosclerosis as assessed by carotid artery intima-media thickness (CIMT) Secondary: To evaluate the safety and tolerability of the above rimonabant regimen in the study population of atherosclerosis patients.

Cardiac surgery using heart and lung machine produces an inflammatory reaction in the body. This leads in few percent of cases to heart, lung, and kidney disturbances that potentially causes death. White blood cells in contact with the heart and lung machine and external surfaces release mediators partly responsible for this. Blood collected by the suction and the blood remaining in the heart and lung machine after its use, can be cleaned by a cell saver before reinfusion, and this might reduce the inflammatory response.

Presence of multiple traditional and nontraditional risk factors of atherosclerosis and cardiovascular disease (CVD) including inflammation in patients with chronic kidney disease (CKD) contribute to high CVD morbidity and mortality in this patient population. Additionally, the traditional approaches towards the therapy of CVD have little impact on CV mortality in these patients. Hydroxychloroquine (HCQ) used as anti-inflammatory in rheumatological disorders, has multiple beneficial properties relevant to the process of vascular disease. The effects of HCQ on atherosclerosis (AS) and vascular disease in CKD is not known yet. Thus, the study hypothesis is that HCQ treatment in individuals with CKD will provide clinically significant benefit in the management of CVD and will provide biological and functional atherosclerotic benefits.

Older patients with co-morbidity are increasingly represented in interventional cardiology practice. They have been historically excluded from studies regarding the optimal management of NSTEACS. Though there are associated risks with invasive treatment, such patients likely derive the greatest absolute benefit from PCI. Small, though highly selective, studies suggest a routine invasive strategy may reduce the risk of recurrent myocardial infarction. The study aims to include, as far as possible, an 'all-comers' population of patients aged 80 and above to define the optimum amount of revascularization required to achieve good outcomes and satisfactory symptom relief for this challenging cohort of patients.
