View clinical trials related to Atherosclerosis.
Filter by:Atherosclerosis and diabetes are related to coronary artery disease and peripheral artery disease. The mechanisms are related to increased reactive oxygen species (ROS) formation and inflammatory cytokine secretion. However, simply using antioxidant or anti-inflammatory therapies has no optimal outcomes. On the other hand, N-acetylcysteine (NAC) which has both antioxidant and anti-inflammatory effects could effectively attenuate ROS production and reduce vascular inflammation. Hence, we will investigate the effect of NAC treatment on the outcomes in patients with advanced atherosclerotic heart diseases and patients with diabetes combined with significant peripheral artery disease.
In this proposal, the investigators will demonstrate the feasibility and noninferiority of telerobotic ultrasonography as compared to traditional manual acquisition in performing a limited carotid Duplex examination and in carotid plaque detection.
This is a Prospective randomized controlled study to evaluate the difference of safety，effectiveness between Excimer Laser Ablation Combined Drug-coated Balloon and drug-eluting stent in treatment of femoral-popliteal artery lesions.
Our study aims to evaluate endothelial function using the non-invasive EndoPAT device, and compare this assessment to traditional cardiovascular risk calculation tools and carotid intima media thickness measurements. We look to determine whether the discovery of endothelial dysfunction provides incremental risk stratification over traditional and CIMT methods of cardiovascular risk assessment.
The purpose of this study will be to understand the underlying mechanism by which PCSK9 inhibition reduces the rate of ischemic stroke seen in the pivotal studies that led to its FDA approval for ASCVD such as ischemic stroke. Those trials (FOURIER and ODYSSEY) enrolled almost 50,000 patients and showed that PCSK9 inhibition therapy is safe and effective. The investigators hypothesize that PCSK9 inhibition lowers the rate of stroke by reducing atherosclerotic plaque, which would be particularly beneficial for patients with intracranial atherosclerosis, who have the highest rate of recurrent stroke of any stroke mechanism.
The purpose of this study is to determine whether Urinary Kallikrein has an additional effect on enhancing collateral circulation in symptomatic intracranial atherosclerotic patients under clopidogrel and aspirin dual antiplatelet therapy.
Psoriatic arthritis (PsA) is a chronic inflammatory disease associated with an increased risk of myocardial infarction (MI). Using coronary computer tomography angiogram (CCTA), it is found that a significantly higher prevalence of high-risk coronary plaque (non-calcified plaque [NCP]), supporting the notion that more aggressive cardiovascular (CV) evaluation strategy should be considered in these patients. Carotid ultrasound screening in this population may be a better alternative than traditional risk score to identify patients at high CV risk as the latter underestimated CV risk. Previous study from our group have demonstrated that achieving treatment target (minimal disease activity [MDA]) can prevent progression of carotid atherosclerosis. Nevertheless, 38% of this Treat to Target (T2T) cohort still had carotid plaque progression. Project description it is hypothesized that combination of a T2T stratgy together with high-intensity rosuvastatin treatment (Group 1: T2T-statin group) is more effective in preventing progression of coronary and carotid atherosclerosis than T2T stratgy alone (Group 2: T2T-only group) in high-risk PsA patients with carotid plaque. The primary outcome is to ascertain the effect of T2T strategy with high-intensity rosuvastain (Group 1: T2T-statin group) on the change in CIMT over a period of 12 months compared with T2T strategy alone (Group 2: T2T-only group)
The purpose of this registry study is to gather real world standard of care (SOC) data on the safety and performance on the Roxwood Medical catheter devices in the treatment of stenotic lesions and CTO.
The aim of this trial will be to test and validate the value of scintigraphy with injection of 99mTc-Annexin-V-128 for the detection of complicated carotid plaques
The CATH-VR study will investigate the effect of virtual reality (VR) on patient pain, anxiety, and radial artery vasospasm during coronary angiography. Our hypothesis is that the use of VR will decrease patient anxiety and pain via validated scoring systems, as well as show a low rate of vasospasm of the radial artery. In addition, we hypothesize that the amount of opioid and benzodiazepine medications utilized for procedural sedation will be lower in the intervention arm. VR has gained recent attraction as an alternative or adjunctive treatment option for pain, but its effect on reducing procedural sedation has not been studied. We propose a single center, randomized control pilot study to further investigate. The patient population will include adults older than 18 years who present for outpatient diagnostic coronary angiography.
