Filter by:The aims of this study are: • To assess 14-3-3 η (eta) protein antibodies in the serum of rheumatoid arthritis patients and its relation to disease activity and severity. • To investigate the role of 14-3-3 η (eta) protein in the diagnosis or assessment of subclinical carotid artery atherosclerosis.
The purpose of this study is to assess the effectiveness of an "inclisiran first" implementation strategy (addition of inclisiran to maximally tolerated statin therapy immediately upon failure to achieve acceptable LDL-C with maximally tolerated statin therapy alone) compared to usual care in an ASCVD population.
Nucleotide-binding oligomerization domain 2 (Nod2) signaling is critical for human health.To figure out the clinical relevance of NOD2 ligands, the investigators plan to evaluate the change of NOD2 ligands in inflammatory bowel diseases (IBD), CRC, atherosclerotic cardiovascular disease (ACVD), and type 2 diabetes mellitus (DM2 ).
The association between inflammation and atherosclerosis is widely known. An increase in morbidity and mortality due to cardiovascular (CV) disease in inflammatory rheumatic diseases has been proved [1-4]. Rheumatoid arthritis (RA) has the greatest CV impact. Scientific societies and expert groups have developed recommendations for preventing cardiovascular risk in these patients [5, 6]. It has also been observed an increased CV risk and greater morbidity in other inflammatory rheumatic diseases such as Ankylosing Spondylitis (AS), psoriatic arthritis (PsA), and inflammatory bowel disease(IBD) [1, 7n, 8]. Ankylosing spondylitis (AS) is a systemic inflammatory disorder of unknown etiology that mainly involves the axial skeleton causing the spine, sacroiliac joints arthritis, and peripheral joints arthritis. Its peak age of onset is between 20-30 years affecting young males with the involvement of extra-articular structures such as eyes, kidneys, heart, lung, vessels, and nerves [9,10]. Aortitis and aortic regurgitation are cardiovascular complications associated with AS. AS is associated with up to 50% mortality rates and cardiovascular diseases are the main causes of these high mortality rates[10,11].
Rotational atherectomy is an established tool to treat blocked arteries in the heart, in which the blockage is due to significant amounts of calcified material. In rotational atherectomy, a rotating instrument is used to break up the calcification before a stent is placed and helps restore blood flow to the heart. However, severely calcified regions are difficult to treat and even after treatment arteries can re-clog and major cardiac events occur. This study will test if rotational atherectomy with the addition of a cutting balloon - a balloon with microsurgical blades on its outer surface which make longitudinal incisions in the calcified area in order to open resistant clogs - will result in increased blood vessel lumen, more optimal stent expansion and decreased cardiac problems compared to current standard treatment.
RESSURE-NIRS registry is designed to investigate clinical and pathophysiological characteristics of NIRS-derived lipid-rich plaque in patients with coronary artery disease. This is an on-going multi-center prospective registry in Japan.
Emotional stress is associated with future cardiovascular events. However, the biological interconnection between brain emotional neural activity and acute plaque instability is not fully understood. Optical coherence tomography-Fluorescence Lifetime (OCT-FLIM) dual modal intravascular imaging is a novel technique that enables comprehensive assessment of structural and biochemical characteristics of coronary atheroma and estimates the level of plaque instability. 18F-fluorodeoxyglucose-positron emission tomography/computed tomography (18F-FDG-PET/CT) enables simultaneous estimation of multi-system activities including emotional stress, arterial inflammation, and hematopoiesis. The present study aims to prospectively investigate mechanistic linkage between coronary plaque instability, stress-associated neurobiological activity, and macrophage hematopoiesis using OCT-FLIM and 18F-FDG PET/CT imaging assessment.
This is a single-center prospective cohort study of predictive factors related to prognosis of ischemic stroke due to large-artery atherosclerosis. From March 1, 2021 to December 31, 2026, 1000 patients with ischemic stroke due to large-artery atherosclerosis who are admitted to the Department of Neurology or Neurosurgery, Tongji Hospital are going to be recruited. Detailed clinical data in emergency room and in-hospital will be obtained from the medical record reviews, and the National Institutes of Health Stroke Scale (NIHSS) and Modified Rankin Scale (mRS) score will be done by certified neurologists to assess the severity of the disease in acute stage and treatment outcome during the follow-up. All cases will undergo routine blood tests, brain magnetic resonance imaging (MRI) and cerebral vascular examination, such as TCD, CTA, HRMR or DSA. The investigators will analyze the in-hospital factors that could predict the outcome to provide more evidence-based suggestions in the treatment and prognosis of atherosclerotic ischemic cerebrovascular disease.
In the entire world most people die from cardiovascular disease. Death is primarily from myocardial infarction (MI) and stroke which are most often caused by rupture of atherosclerotic plaques. Patients with high-grade, i.e. ≥ 70% carotid artery stenosis are at especially high risk. Magnetic Resonance Imaging (MRI) studies show that two features inside plaques that are associated with the risk of plaque rupture and subsequent cardiovascular events are: lipid rich necrotic core (LRNC) and intraplaque hemorrhage (IPH). MRI studies on carotid artery plaques typically relies on proton-density-weighted fast-spin echo, blood-suppressed T1- and T2-weighted gradient-echo sequences. The end-result is nonquantitative measures, where plaque features are identified due to their relative signal intensity. To address these problems of non-specificity, we developed a quantitative MRI (qMRI) technique based on Dixon sequences. The study intention is to enable in-depth analysis of plaque features and their relation to clinical data. For example there is an insufficient understanding of associations between lipid biomarkers and plaque contents. Our hypothesis is that we can identify quantitative changes in both plaque and lipid biomarkers after one year of optimized cardiovascular risk management (including treatment with lipid lowering drugs), and establish if there is any associations between these features. Because there is a well-established link between systemic inflammation and the presence of atherosclerotic plaques we will also study the relationship between LRNC and IPH as measured by qMRI versus circulating markers of inflammation. Method: Patients with known carotid stenosis are invited for a baseline visit and a 1-year follow up visit. The study visits include clinical assessment, blood tests, patient interview and magnetic resonance imaging of the carotid arteries. All participants are offered optimized cardiovascular risk management through the individual assessment by the study physicians.
Patients will undergo intracoronary imaging using combined optical coherence tomography-fluorescence lifetime imaging (OCT-FLIm) during percutaneous coronary intervention, and the obtained imaging data will be used to assess the efficacy of this dual-modal catheter imaging strategy in characterizing high-risk plaque.
