The purpose of this pilot study is to evaluate an innovative 8-wk stress reduction program called Resilience, Stress and Ethnicity (RiSE) program designed to reduce chronic stress associated with perceived discrimination among African Americans. African Americans residing in the Maywood community between the ages of 25 and 75 with at least one cardiovascular disease risk factor such as being overweight, having high blood pressure, or diabetes will be enrolled. The following specific aims will be addressed: Aim 1: Determine the feasibility and acceptability of the program as a strategy to reduce chronic stress in African Americans within the Maywood and surrounding community. Aim 2: Examine the extent to which training in RiSE (1) improves psychological well being, (2) decreases inflammatory burden, and (3) reduces cardiovascular risk in African Americans Participants will be randomized to either the RiSE program or the control (no intervention group). Participants will provide blood and saliva samples as well as complete written questionnaires asking them questions about their health, well-being, and early life at the start of the study, half way through the study (at 4 weeks), at the completion of the intervention (8 weeks) and 3 months after the completion of the intervention).
EVOLVE 4.5/5.0 is a prospective, single-arm, multi-center observational (standard of care) trial intended to confirm the safety and effectiveness of the SYNERGY 4.50 mm and 5.00 mm Coronary Stent System for the treatment of patients with coronary artery disease in large vessels (≤ 28 mm in length, by visual estimate, in native coronary arteries > 4.00 mm to ≤5.00 mm in diameter, by visual estimate). This Post Approval study is a cohort associated with the SYNERGY MEGATRON Post Approval Study, which is registered under ClinicalTrials.gov ID: NCT04807439.
Sonodynamic therapy (SDT) is a new treatment for carotid atherosclerotic plaque. The purpose of this study is to evaluate the safety and initial effectiveness of this technique.
Heart disease and failure are the major causes of mortality and morbidity worldwide, despite significant advances in medical technologies in the diagnosis and treatment of the disease. Cardiovascular disease may arise for various reasons including the steadily increasing incidence of obesity, type 2 diabetes, genetic, environmental, dietary and lifestyle factors. Besides all these, there is much evidence suggetsing that inflammation is an important player in the pathogenesis of heart disease, as well as atherogenesis and atherosclerosis.
The purpose of this study is to investigate the effect of interrupting prolong sedentary behavior with interval exercise on postprandial metabolism following a high fat glucose tolerance test.
The main purpose of this single-center study is to determine the spectrum and levels of cardiospecific circulating microRNAs in patients with different stages of atherosclerosis according to 640-slice multispiral computed tomography (MSCT).
Coronary intermediate lesions generally refer to lumen narrowing with diameter stenosis% (DS%) between 50% and 70% on angiography. Prognosis varies significantly among patients with intermediate lesions, and some lesions progress rapidly leading to adverse cardiovascular events. Therefore, accurate risk stratification is important and will help clinicians identify patients at high risk of adverse events. The aim of study is to identify independent risk factors for major adverse cardiovascular events (MACE) among patients with intermediate lesions. The study is a prospective, single-center, ongoing, observational study, which aims at enrolling approximately 1389 patients with intermediate coronary lesions. After enrollment, the following data are collected for each participant: baseline characteristics including demographics, clinical presentation, traditional risk factor, diagnosis and management; lesion characteristics assessed by coronary angiography; quantitative flow reserve; lab tests including blood chemistry, blood lipid, hemoglobin A1C, cardiac biomarker, BNP, et al. Patients are followed up at 2 year for primary outcome including death, myocardial infarction and repeat unplanned revascularization. A risk prediction score will be established and validated for major adverse cardiovascular disease at two-year follow-up.
The current study will test the central hypothesis that Glycine supplementation in humans improves Lipid profile and therefore reduces the risk of Atherosclerosis. Secondary outcomes including Insulin sensitivity and parameters related to Metabolic Syndrome (MetS) will also be measured. Furthermore, a mechanistic study in an ex-vivo model will test the hypothesis that Glycine via its key biosynthetic pathway involving Serine Hydroxymethyltransferase 2 (SHMT2), is athero-protective by inhibiting Sterol regulatory element-binding protein 2 (SREBP2)-mediated cholesterol biosynthesis in murine macrophage-like cell line.
Experimental models have linked lipid lowering therapies with systemic inflammation; however, relatively little is known about this network in clinical populations and specifically how it changes with PCSK9 inhibition. The eligible subjects will have 6 visits in 13 to 16 weeks and will have Repatha/placebo 140mg subcutaneous every 4 weeks for 3 times since randomization visit, blood tests will be done in each visit to evaluate the effects of evolocumab upon biocellular markers potentially altered by PCSK9 inhibition in a population of type 2 diabetes patients with microvascular dysfunction. Primary Aims: Determine the ACUTE and SHORT-TERM effects of PCSK9 inhibition with evolocumab on biocellular markers of inflammation, immune mediated thrombosis and rheology. The data from this trial will be used to support a clinical trial to assess the role of PCSK9 inhibition in type 2 diabetes patients with cardiac microvascular dysfunction. Secondary Aims: 1. To define the association between PCSK 9 concentrations and immune-related phenotype. 2. To define the association between Lp(a) concentrations, oxidized phospholipids (OxPL), ApoB, biocellular markers of inflammation, tissue factor and immunothrombosis.
