Filter by:A prospective, randomised, open-labelled, multi-center study. The aim of the Steno 1 study is to test multifactorial intervention in individuals with type 1 diabetes at high risk of CVD with ambitious treatment targets. We will include 2000 participants. Follow-up is 5 years.
The main objectives of PPS3-2 are (i) to describe the dynamics of vascular aging and baroreflex sensitivity 12 to 16 years a part, (ii) to identify their determinants, and (iii) to quantify the subsequent risk of cardiovascular diseases.
The focus on this application is low-income, rural patients, since cardiovascular disease (CVD) prevalence is 40% higher among rural than urban residents. Health behavior counseling and follow-up care are required for patients with an elevated body mass index who have increased risk for CVD. Counseling is most effective when developed with, and tailored to, the patient and offered with resources that support healthy food intake and physical activity. Resource referral and follow-up is particularly important in rural low income residents who often have more severe social needs that impede healthy behaviors. The proposed research will leverage the candidate's digital health tool (PREVENT) for healthcare teams to use within the clinic visit. PREVENT visually displays patient-reported and electronic health record (EHR) data to facilitate counseling and deliver tailored physical activity and healthy food intake goals and resources. PREVENT may improve the quality of required care and promote cardiovascular health equity. This research will: 1) collaborate with rural and clinic partners to modify and integrate the PREVENT tool for low-income, rural patients with obesity (Aim 1); and 2) conduct a pilot pragmatic clinical trial of PREVENT to optimize feasibility, acceptability, appropriateness, and potential health equity impact.
Cardiac MRI (CMR) scanning allows doctors to create detailed images of the heart. However, the need for experienced cardiac radiographers to perform each scan can make CMR's delivery difficult, and some patients in the UK wait more than half a year for a scan. These radiographers must take pictures of different part of the heart, termed "views", each of which must be precisely positioned. The investigators believe they can revolutionise CMR, by using artificial intelligence to automatically position the views so radiographers can focus on more difficult tasks. The investigators have used a retrospective database of pseudonymised (anonymised and linked) CMR scans at our hospital to create these artificial intelligence (AI) algorithms, and they have validated them retrospectively on previous studies. The investigators now wish to test the algorithms prospectively. In this study, the investigators will recruit patients undergoing clinical CMR scans. In addition to the routine images acquired by expert radiographers, the investigators will require a duplicate set of images, positioned and planned by the AI algorithms. The investigators will then compare, within each patient, the AI-planned and expert-radiographer-planned scanning in terms of both speed and image quality.
Patients with type 2 diabetes and moderate to severe coronary artery stenosis who were treated at Zhejiang Second Hospital and cooperative hospitals were randomly divided into a patient management group based on continuous continuous glucose monitoring (CGM) or a patient management group based on HbA1c. Both groups controlled cardiovascular risk factors according to the Chinese Guidelines for the Prevention and Treatment of Type 2 Diabetes (2020) and the ADA Guidelines for the Prevention and Treatment of Diabetes (2023), and conducted HbA1c testing every 3 months. In the CGM-based glucose management group, CGM measurements will be performed at baseline and at 6, 12, 18, and 24 months. In the CGM-guided treatment group, the target TIR>70%, TBR<4%, TAR<25%, and HbA1c<7.0%; in the HbA1c-guided treatment group, the target HbA1c<7.0%. The primary endpoint was major adverse cardiovascular events (MACE: CV death, nonfatal myocardial infarction, nonfatal stroke).
Wilson disease (WD) is a rare autosomal recessive disorder caused by a genetic defect in ATP7B resulting in limited excretion of excess copper into the bile Pathological copper accumulation occurs in the entire body, with the liver and the brain being primarily affected
Coronary angiography-derived FFR assessment (AngioQFA) is a novel technique for physiological lesion assessment based on 3-dimensional (3D) quantitative coronary angiography (QCA) and virtual hyperemic flow derived from contrast frame count without drug-induced hyperemia. The goal of this prospective, multicenter trial is to compare the diagnostic performance of AngioQFA with invasive FFR as the reference standard. The secondary purpose is to compare the diagnostic accuracies of the computational fluid dynamics (CFD)-based index of microcirculatory resistance (IMR) using wire-based IMR as the reference standard.
Chronic kidney disease (CKD) is a long-term condition where the kidneys do not work as well as they should. End-stage kidney failure (ESKD) is the final, irreparable stage of chronic kidney disease (CKD), where kidney function has worsened, so the kidneys can no longer function independently. At this stage, dialysis is required to remove waste products and excess fluid from the blood. There are two types of dialysis. In haemodialysis (HD), blood is pumped out of the body to an artificial kidney machine and returned to the body by tubes that connect a person to the machine. In peritoneal dialysis (PD), the inside lining of the belly acts as a natural filter. PD has the advantage of being gentler on the heart. HD causes significant stress to the heart by reducing the blood flow to the heart muscle, resulting in heart failure, irregular rhythms, and eventually sudden heart death. A large observational study showed that HD patients had 48% worse survival in the first two years than PD patients. Several molecules ('biomarkers') can be detected in blood and inform doctors of heart damage. Studying the form and function of proteins (Proteomics), including how they work and interact with each other inside cells in patients, could help identify the onset of heart problems. HD patients are also prone to body fat changes (cholesterol/lipids). Due to high cholesterol, there is build-up on the walls of arteries, causing their hardening. In HD patients, this process is faster due to abnormalities in lipid structure. Therefore, studying the heart biomarkers, protein, and lipid makeup of HD patients may help to find people at substantial risk of heart and vascular problems and if they are likely to become unwell due to these heart problems.
The aim of this study is to determine whether and how serum concentrations of the used medicinal products, including their metabolites, correlate with selected clinical indicators of heart failure (NT-proBNP concentration, 6-minute walk test, quality of life questionnaire, echocardiographic parameters, hospitalization for HFrEF, length of survival).
The objective of this study is to evaluate the safety and effectiveness of the clinical and technical performance of the VRS100 system with disposable surgical kit in the delivery and manipulation of coronary guidewires and stent/balloon systems for use in percutaneous coronary interventions (PCI).
