Active clinical trials for "Atherosclerosis"

This study is to evaluate the effect of rosuvastatin 10-20 mg on carotid atherosclerosis progression in Chinese patients by evaluating the change in the percentage of volume of lipid rich necrotic core (LRNC) using high-resolution magnetic resonance imaging (MRI) after 24-months treatment.

Background: Type 2 Diabetes Mellitus (T2DM) is associated with an increased burden for cardiovascular disease (CVD). Multifactorial interventions are necessary to reduce the CV risk in T2DM. Bariatric surgery appears to be an alternative for the multifactorial intervention in T2DM associated with obesity. Data have shown, that clinical trial aiming at the control of CVRF in T2DM may not translate in the reduction of CV events. Hypothesis: Intensive medical treatment (IMM) including Roux-en-Y Gastric Bypass (RYGBP) could be superior in the control of the progression of subclinical atherosclerotic disease, as evaluated by carotid ultrasound, in subjects with T2DM and a BMI between 30.0 and 34.9 kg/m2.The primary aim of the study is To compare the effects of intensive medical treatment (IMM) including Roux-en-Y Gastric Bypass (RYGBP) and IMM alone on the progression of the carotid intima media thickness (CIMT) at 24 months after entry into the trial relative to baseline.Methodology: Two-year Randomized Clinical Trial, including 240 patients

The aim of this study is to explore and identify the effects of acetylcysteine, a common mucolytic with anti-oxidant property, on alleviating the damage caused by increased oxidative stress in hemodialysis patients.

This will be a randomized, placebo-controlled, clinical trial carried out on moderately hypercholesterolemic subjects who will consume 3 g per day of beta-glucans, in order to evaluate the effects on lipid profile, glycemia and intestinal function

To assess the efficacy and safety of moderate-intensity rosuvastatin/ezetimibe compared to high-intensity rosuvastatin in high atherosclerotic cardiovascular disease risk patients with type 2 diabetes

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.

Rheumatoid arthritis (RA) is a condition associated with a high incidence of cardiovascular disease (CV), primarily as a result of accelerated atherosclerosis . Patients with RA also have a high prevalence of metabolic syndrome (MS) The state of chronic inflammation in RA patients contributes to increased CV risk. Deregulation of both genetic and serological adipocines, MS biomarkers, and biomarkers of endothelial activation and inflammation also contributes to the increased CV risk in these patients. An increased incidence of abnormal carotid intima-media thickness (cIMT) values and carotid plaques, considered surrogate markers of subclinical atherosclerotic disease, has also been described in patients with RA. Positron emission tomography/computed tomography (PET/CT) is a noninvasive imaging technique useful for the evaluation of inflammation (by 18F-FDG uptake) and mineralization (by 18F-NaF uptake) in carotid atheroma plaque. Atherosclerosis and RA share many common inflammatory pathways, and the mechanisms that lead to synovial inflammation are similar to those seen in atherosclerotic plaque. Interleukin (IL)-6 is a key pro-inflammatory cytokine involved in both the pathophysiology of RA and the development of atherosclerosis. Sarilumab is a human monoclonal antibody against the IL-6 receptor that has been shown to be effective in patients with RA, improving symptoms, as well as at the functional and radiographic levels. Treatment with IL-6 receptor inhibitors has been described to result in a modulation of lipid metabolism, mediated by a reduction in lipoprotein (a) (Lp(a)) and an improvement in the anti-oxidant function of high-density lipoprotein (HDL) . In this regard, Sarilumab may have beneficial effects in RA patients on MS, which is implicated in the development of atherosclerotic disease. Information regarding the beneficial effect of IL-6 receptor blockade on atheroma plaque formation and its effect at the vascular level in RA patients is scarce.

The OPTIMAL is a single-center, randomized trial to evaluate the efficacy of CGM-based glycemic control on atheroma progression in T2DM patients with CAD by using serial intravascular ultrasound (IVUS) and near-infrared spectroscopy (NIRS) imaging. A total of 90 eligible subjects will be randomized 1:1 into 2 groups to receive either CGM-based glycemic control or HbA1c-baded glycemic management. Coronary angiography and NIRS/IVUS imaging is repeated at the end of the assigned treatment period. Results: The primary endpoint is the normalized absolute change in total atheroma volume from baseline to 12 months. The secondary endpoints include (1) the absolute change in percent atheroma volume, (2) the percent change in lipid core burden index, (3) the change in coefficient variance measured by CGM, (4) the change in atherogenic markers (high-density lipoprotein functionality, proprotein convertase subxilisin/kexin type 9 and fatty-acid binding proteins), and (5) the frequency of hypoglycemia. Safety will also be evaluated.

In addition, studies have found that indobufen can inhibit coagulation function in rats. Compared with aspirin, the duration of antiplatelet efficacy of indobufen was shorter, and the platelet function recovered completely 24 hours after drug withdrawal. However, there are few studies on the antiplatelet efficacy of indobufen. The investigators' previous study found that the inhibitory effect of indobufen 100 mg Bid on COX system in atherosclerosis or healthy volunteers was equivalent to that of aspirin 100 mg QD, but the inhibitory effect on platelet COX-1 channel was significantly weaker than that of aspirin 100 mg QD. In view of this, this study intends to investigate the antiplatelet effect of indobufen 200 mg Bid in patients with coronary atherosclerosis by comparing it with conventional-dose aspirin 100 mg QD.
