Acute Exposure to Diesel: Prolong Effects on Inflammation and Vasculature
AtherosclerosisCross-over double-blind study. Healthy subjects will be exposed to diesel exhaust fumes and/or filtered air during a 2-hour session. Several parameters will be assesed i.e. endothelial function will be assessed with flow mediated dilation (FMD) techniques, arterial stiffness with pulse wave velocity (PWV) and reflected waves with augmentation index (AIx). C reactive protein (CRP), fibrinogen, protein C levels and protein S activity will be also measured. Heart rate variability and standard deviation of normal to normal intervals R-R intervals (SDNN) will be used to assess sympathetic activity. Measurements were assessed before, 2 and 24 hours after diesel exposure.
Study on the Mechanism of Prevotella Copri Promoting the Occurrence and Development of Atherosclerosis...
AtherosclerosisMainly studying the correlation between the abundance of Prevotella copri (P.copri) in the gut microbiome and the progression of clinical coronary atherosclerotic heart disease(CAD) patients, and confirming that an increase in P.copri abundance will accelerate the occurrence and development of CAD disease, accompanied by an increase in serum Branched chain amino acid(BCAA), lipopolysaccharide(LPS), and serotonin; For people who mainly consume a high carbon water diet, blood sugar is a stronger risk factor for AS compared to blood lipids; Explore the KAP status(Study composes of Knowledge, attitude, and practice) of coronary heart disease patients and their caregivers regarding coronary heart disease and diet, and investigate whether the popularization of science after KAP investigation can change the treatment effect of patients.
Evaluation of Impaired Mobility in Chronic Illness Constitution of a Cohort
Joint OsteoarthritisAtherosclerosis of the Distal Arteries6 moreChronic illness is a public health issue and mobility loss is frequent in this population. Among its' multiple physical and psychological consequences, increased mortality and cardiovascular morbidity seem the main concern. Therefore, the exploration of locomotor deficiencies, physical capacities and metabolism of patients with chronic illnesses constitutes a major challenge both for the treatment of causal pathologies, as well as for evaluating the impact of therapeutic interventions, the benefit of which will be an improvement in physical capacities and ultimately mobility. In view of the hypothesis of an increase in the prevalence of mobility disorders in this population, this approach is part of a logic of screening and improving the effectiveness of the care of these patients with a multidisciplinary evaluation of individual risks. The EVALMOB protocol was designed in order to try to determine a standard profile of "dysmobility" in patients with chronic illness
Text Education About Cardiovascular Health and HIV (TEACH-HIV)
HIVHuman Immunodeficiency Virus2 moreThe overall objective is to evaluate the efficacy of educational text messages to reduce cardiovascular risk among persons living with HIV (PLWH).
Effect of Evolocumab on Saphenous Vein Graft Patency Following Coronary Artery Bypass Surgery
Coronary Artery Bypass Graft SurgeryAtherosclerosis1 moreThe purpose of this study is to determine if evolocumab added to regular statin therapy improves vein graft patency after coronary artery bypass graft (CABG) surgery.
PET Imaging of Inflammation and Lipid Lowering Study
HypercholesterolemiaHypercholesterolemia3 moreWhile 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) imaging has been used as an early marker of drug efficacy in numerous clinical cardiovascular drug trials, as a glucose analog, its signal in the vasculature lacks inflammatory cell-specificity. Moreover, high background 18F-FDG signals from the myocardium often preclude coronary artery imaging, despite attempts to suppress myocardial tracer uptake by dietary manipulation. These limitations of 18F-FDG for measuring changes in vascular inflammation arising from drug intervention highlight important unmet needs, which might be overcome by using a somatostatin receptor subtype-2 (SST2) PET tracer.
microRNAs in the Diagnosis of Atherosclerotic Plaque Instability
Atherosclerosis of ArteryIt's a non-randomized, intervention, prospective, single-center study. The aim of the work is to identify of biomarkers of unstable atherosclerosis in brachiocephalic arteries Tasks: identify microRNAs, the expression of which is characteristic of unstable atherosclerotic lesions; to assess the relationship of miRNA and trimethylamine N-oxide with the progression of unstable atherosclerotic lesions; to determine the effect of the level of plasma trimethylamine N-oxide on the progression of atherosclerotic lesions.

HypercholesterolemiaCardiovascular Risk Factor3 moreThis clinical study aims to assess the efficacy of 6 weeks 2.5g dose of TOTUM-070, a mix of 5 plant extracts, on lipid metabolism and cardiovascular health in individuals at increased cardio-metabolic risk.
Vascular Inflammation ReDuction and Perivascular Fat Imaging by Computed Tomography
Coronary Artery DiseaseAtheroscleroses2 moreThe goal of this clinical trial is to compare the effect of standard of care management vs. CaRi-Heart based management on vascular inflammation in patients with increased Fat Attenuation Index-Score. The main questions it aims to answer are: Does treatment intensification reduce vascular inflammation detected by perivascular fat imaging to a greater extent than standard of care treatment? Do changes in vascular inflammation biomarkers correlate with changes in lipid metrics or inflammatory biomarkers, such as interleukin-6? Participants will be randomized either to standard of care treatment or intensified treatment with maximum dose of atorvastatin +/- low dose of colchicine. After their inclusion, study participants will be followed-up for 6 months with regular monitoring for adverse events and blood will be drawn at 3 and 6 months. After the 6-month follow-up, participants will undergo CCTA imaging for fat attenuation index measurements. Researchers will compare standard of care and vascular inflammation-based treatment to see if inflammation-based treatment is more potent against vascular inflammation.
Cluster Randomized Trial of a Digital Quality Improvement Intervention on LDLCholesterol Control...
Cardiovascular DiseasesAtherosclerosis1 moreElevation in low density lipoprotein (LDL) cholesterol (LDL-C) is a causal risk factor for atherosclerotic established cardiovascular disease (ASCVD). Reduction of LDL-C with statins has been clearly demonstrated as a robust and cost-effective way of reducing the burden of ASCVD in individuals at risk. ASCVD is the leading cause of death and disability in Brazil and therefore prevention guidelines recommend LDL-C reduction with the aim of reducing disease burden in individuals at risk. Studies have shown a clear hiatus on awareness and treatment of cholesterol in Brazil. Thus, it became imperative to develop knowledge translation projects aiming at bridging the gap between science and clinical practice and ultimately leading to better outcomes. Cluster randomized clinical trials are the highest quality type of clinical research to test educational and active interventions aimed at changing behaviors or clinical practices. Therefore, this study is a pragmatic cluster randomized trial to assess the effect of a digitally enabled quality improvement intervention on LDL-C control in atherosclerotic established cardiovascular disease (ASCVD) patients.
