Active clinical trials for "Atherosclerosis"

Double-dose statin regimen achieves merely 6% of decrease in low-density lipoprotein cholesterol (LDL-C) levels, whereas the risk of side effects increased largely. The investigators' previous pilot study (NCT01686451) has suggested that red yeast rice was of similar lipid-lowering efficacy while was associated with less fatigue than statins. The purpose of this study is to evaluate the efficacy and safety of combined therapy with red yeast rice and low-dose atorvastatin in persons with mild atherosclerotic cardiovascular disease and who qualified for statin therapy according to national guidelines.

Background: Effectiveness of Percutaneous transluminal angioplasty and stenting (PTAS) on prevention of events of stroke and death in patients with symptomatic intracranial atherosclerosis (ICAS) is controversial. Aim: to determine whether PTAS plus medical treatment (MT) are superior to MT alone in preventing events of stroke and death in patients with symptomatic ICAS. Methods: The investigators will carry out a randomized controlled trial in 3 hospitals in China. A total of 198 patients with ICAS will be randomized into 2 groups: PTAS+MT and MT group. All patients will receive aspirin (100 mg daily) and clopidogrel (75 mg daily) immediately after randomization, and patients in PTAS+MT group will receive surgery within 5 days after randomization. The patients will be followed up for 1 year after randomization and assessed for events of stroke and death at 30 days and 1 year after randomization, the incidence of recurrent ischaemic stroke in the stenting-involved vascular territory at 30 days and 1 year after randomization, incidence of in-stent restenosis at 1 year after randomization,etc.

The purpose of this study is to determine whether olmesartan medoxomil is effective in the treatment of coronary atherosclerosis progression and epicardial adipose tissue(EAT) volume reduction in patients with coronary atherosclerosis detected by coronary CT angiography(CCTA).

In this randomized double-blinded clinical trial, 400mg of hydroxychloroquine will be given daily to people over the age of 65 years with moderate-severe obstructive sleep apnea for 8 weeks. The aim of this study is to test whether hydroxychloroquine can improve endothelial function.

The Oral treatment of Colchicine in Argentina (ORCA) trial is a prospective, randomized, multicenter trial to included 450 patients with indication for myocardial revascularization with PCI between a group to be treated with BMS plus oral colchicine (OC) for three months, which should be administered at the time of PCI, these patients they would receive 0.5 mg twice a day per 3 months compared to the other group of patients who will be treated exclusively with last generation of DES.

The investigators propose a prospective, randomized, double-blind, placebo-controlled study. The purpose of the study is to evaluate the safety and efficacy of an anti-inflammatory agent methotrexate in a cholesterol-rich non-protein nanoparticle (MTX-LDE) in patients with stable coronary disease. Patients with multi-vessels stable coronary disease will be randomized to receive MTX-LDE IV or placebo-LDE IV each 7 days for 12 weeks. The primary and main secondary endpoints will be analyzed by coronary and aortic CT angiography, that will be performed before the first treatment cycle, four weeks after the last drug infusion and 12 months after randomization. Patients will undergo clinical and laboratory safety evaluations before each treatment cycle, four weeks after the last cycle and 12 months after randomization. An algorithm for drug suspension based on clinical and laboratory finding will be followed.

The purpose of the prospective, randomized and a multicenter trial is to compare clinical outcome in patients presenting with ACS, treated with PCI using Optimax-BAS versus Synergy-EES. Second objective is to explore whether the Optimax-BAS use is superior compared with Synergy-EES use with respect of hard end points (cardiac death, MI and major bleeding).

Subclinical hypothyroidism (SCH) is a common condition affecting 3-10% of the general population, especially in women older than 50 years old. It is controversial whether SCH can lead to increased risks of cardiovascular (CV) disease and whether treatment with L-thyroxine reverses these risks. The present study was designed to evaluate the effect of L-thyroxine treatment in SCH on lipid profile, atherosclerosis, endothelial function, serum inflammatory factors and adipocytokines.

The purpose of this study is to evaluate the effects of Sarpogrelate in endothelial progenitor cells of patients with atherosclerosis.

Atherosclerotic cardiovascular disease is a leading cause of mortality in our countries. Clinically, symptoms could be chest pain suggesting stable angina. Atherosclerosis is influenced by cardiovascular risk factors which obesity (Body Mass Index>30). Obesity is associated with an increase risk of cardiovascular complications. Lipoprotein(a) is regarded as an independent risk factor for premature cardiovascular disease. Lp(a) is composed of low-density lipoprotein - like particle bound to glycoprotein molecule: apolipoprotein(a). Plasma levels are determinated to more than 90% by genetic factors (no significant influence of statin, weight, lifestyle factor: diet, exercise). Two study with few patients have found that aspirin lowers serum Lp(a) levels. Elevated Lp(a) is a risk factor for recurrent coronary events in obese patient. Atherosclerosis is associated with imbalance of coagulation. TFPI (tissue factor pathway inhibitor) is the earliest inhibitor of the blood coagulation process, natural direct inhibitor of tissue factor. In-vitro, TFPI activity is inhibited by high Lp(a) . The aim of this study is to research reverse association between Lp(a) and TFPI activity in obese patient with chest pain like stable angina suggesting atherosclerotic heart disease and effect of aspirin.
