Filter by:The study is intended to estimate the proportion and clinical management of people with type 2 diabetes having atherosclerotic cardiovascular diseases or who are at high risk to develop atherosclerotic cardiovascular diseases. Participants will be asked to give information about their health. Partipants will continue normal way of life and will not get any medication other than those prescribed to them by the doctor. The study will last for about 6 months.
The purpose of this study is to evaluate the safety and effectiveness of CERENOVUS ENTERPRISE 2 intracranial stent implantation in treatment of participants with severe symptomatic intracranial atherosclerotic stenosis.
The Kitasato PCI Registry is a single-center, observational, prospective study. This study aims to investigate the impact of characteristics in clinical manifestation, patients' background, procedure of percutaneous coronary intervention (PCI), and pre/post PCI culprit/nonculprit lesion observed by intra-coronary imaging modality on clinical outcomes.
In adult patients presenting to emergency departments within 24 hours of symptom onset with suspected acute stroke, we aim: 1. to identify early brain- and pathology-specific circulating, whole blood, plasma and serum panorOmic biomarkers that enable early acute stroke detection, diagnosis, dynamics, differentiation, monitoring, prediction and prognosis. 2. to identify early brain- and pathology-specific, panorOmic biomarkers in saliva that enable early acute stroke detection, diagnosis, dynamics, differentiation, monitoring, prediction and prognosis. 3. to derive biomarker platforms of models for early acute stroke detection, diagnosis, dynamics, differentiation, monitoring, prediction and prognosis 4. to validate these models in independent and external datasets
For children and adolescents with diabetes, the pathological process of atherosclerotic cardiovascular disease(ASCVD) can exist in early childhood and progress rapidly to subclinical ASCVD. This study intends to explore the models for the prediction of ASCVD risk in childhood and teen-age onset diabetes with different types.
To evaluate and compare the change of plaque composition by VH-IVUS imaging in subjects who take NXT and placebo in post-PCI of AMI patients during 12 months follow-up.
The REDUCE-IT Canada SA Study is a cross-sectional study aiming to determine the proportion of study participants who meet the Health Canada-approved indication for icosapent ethyl (IPE;Vascepa®).
Chronic mesenteric ischemia (CMI) is often caused by narrowings in the arteries providing blood to the intestines. Endovascular stent placement is considered the preferred treatment for this condition. Guidelines increasingly support the use of so called covered stents (CS) in stead of bare stents (BMS) for this use but the level of evidence for this is limited. Using CS incur additional costs for healthcare short-term but may prevent recurrence of narrowing and symptoms postoperatively benefitting patients and healthcare. Study Objective: To evaluate the outcomes after stenting of mesenteric arteries using BMS or CS. Study Outcome: Primary stent patency 1 year after placement The trial will also evaluate complications, how often stents need to be reoperated, Quality of Life (QoL) and reasons for subjects death Method: This is a so called prospective, randomized controlled trial comparing CS vs. BMS. This means that one patients have agrred to treatment they will be randomly selected for treatment with either CS or BMS . The stent metal structure is identical in the two implants and the only difference is the graft covering, making this study unique. The study will also collect blood samples for a biobank that will be used to study markers of disease and how these effect treatment outcomes. All patients referred to the Department of Vascular Surgery due to CMI are considered for inclusion if they havechronic symptoms consistent with CMI, significant stenosis or occlusion of the superior mesenteric artery and are > 18 years Subjects not able to provide informed consent or who have non atherosclerotic cause of CMI, signs of acute loss of blood flow to the intestines cannot participate. Previous stent treatment in the superior mesenteric artery, pregnancy, allergies to contrast or stent materials are also reasons for not being included in this trial. Side effects, risks and disadvantages for participants The risk for procedure-related complications is less than 5% and similar in both study groups. Most short-term complications are related to vascular access sites and consist of local bleeding and thrombosis. Other potential complications include impaired renal function due to contrast use, contrast allergy, arterial dissection and death.
Atherosclerosis is the underlying cause of the majority of cardiovascular diseases, including myocardial infarction and strokes, and results in tremendous morbidity and mortality. A Western-type diet is a major risk factor for atherosclerosis because of the high saturated fat, cholesterol, and refined carbohydrate contents. Dietary strategies to reduce cardiovascular disease burden therefore focus on restriction of saturated fat, cholesterol, and refined carbohydrates whereas "lean" protein intake is recommended and has become popular. However, results from studies conducted in animal models suggest high dietary protein intake is also atherogenic. The investigators' extensive preliminary data in animal models show that dietary protein increases atherosclerotic plaque formation and size and promotes necrotic core formation, a characteristic of rupture-prone plaques. The goal of the current proposal is to provide deeper insights into the relationship between protein intake and the pathogenesis of atherosclerosis by studying the mechanisms involved in protein-mediated atherogenesis and formation of necrotic plaques. The overarching hypothesis is that high protein intake drives atherosclerosis via leucine-mediated mTORC1 signaling in macrophages, which inhibits macrophage mitophagy and aggrephagy and stimulates macrophage proliferation. Furthermore, the investigators hypothesize that proteins from animal sources are more atherogenic than proteins from plant sources, because animal proteins contain more leucine than plant proteins. The investigators will test these hypotheses by using a sophisticated array of experimental strategies, including assays in primary macrophages and human monocyte-derived macrophages and genetically engineered mouse models. In addition, they will begin to translate the results obtained in vitro and in animals to people, and explore approaches to pharmacologically target the pro-atherogenic pathways as novel cardiovascular therapeutics. This proposal represents a paradigm shift in how a Western-type diet affects vascular health which has important implications since many adults in Western societies consume excess protein and dietary protein is heavily marketed for its presumed beneficial health effects.
This study intends to build a model through deep learning that can automatically and accurately detect plaques, calculate the lumen stenosis rate and evaluate the stability of plaques based on the carotid transverse axis dynamic ultrasound images and contrast-enhanced ultrasound images, so as to comprehensively evaluate the possibility of carotid plaques. cardiovascular risk. The successful development of this study will automatically simulate and reproduce the whole process of carotid plaque assessment by clinical sonographers. Solve the problem of ultrasonic inspection equipment and experience dependence. It is expected to carry out large-scale population intelligent screening, providing new ideas for early prevention and treatment. Especially in medically underdeveloped remote areas and the lack of experienced sonographers, it has great practical value in clinical health care and can bring greater social and economic benefits.
