Filter by:The study is a epidemiological, cross-sectional study in a mainly rural area of Denmark in Denmark. Life expectancy is shorter, morbidity is higher, and social problems more prevalent than in the urban areas of the country. The population study aims at examining complexities of environmental, hereditary, lifestyle, and social factors as determinants and predisposing factors for morbidity, health, and quality of life. The study will cover physical, mental, and social dimensions and examine family patterns and subgroups. The study will provide baseline information for later follow-up.
Two Intensive Life Style Intervention Programs in Related Caregivers of Preschool Children Substantial strides have been made in the treatment of acute cardiovascular conditions, such as myocardial infarction and stroke, however, the global burden of cardiovascular disease (CVD) continues to rise at an alarming rate. Furthermore, despite the abundant data demonstrating a greater burden of CVD in racial/ethnic minorities, and many specific interventions aimed at changing risk factor patterns or behaviors in racial/ethnic minorities, health disparities persist. In the present study, the investigators seek to evaluate the impact of a multifaceted and comprehensive lifestyle intervention coupled with atherosclerosis imaging on reducing cardiovascular risk among minority adults living in Harlem, New York. The investigators believe that holistic, multi-dimensional individual and peer-to-peer intensive lifestyle interventions involving parents/caregivers of preschool children will be effective in producing favorable change in their behaviors, which will be sustained over time. The primary hypothesis of the study is that aggressive lifestyle interventions will be more effective in improving healthy behaviors and biological correlates in at-risk adult parents and/or caregivers of preschool children in Harlem, NY. In aim 1, as an initial pilot study, the investigators will identify the contextual factors, facilitators and barriers that may impact the implementation of a lifestyle intervention program for adults in Harlem, using qualitative research methods. In aim 2, the investigators will determine the impact of two intensive lifestyle interventions on promoting and improving healthy behaviors and biological parameters to lower cardiovascular risk, the impact of the knowledge of presence of atherosclerosis on health behaviors and the impact of these lifestyle interventions on atherosclerosis among approximately 600 asymptomatic at-risk adults. Finally, in aim 3, the investigators will evaluate the sustainability of the impact of the two intensive lifestyle interventions on healthy behaviors and biological parameters approximately 12 months after the intervention program ends.
BACKGROUND - Vascular surgical patients often receive red blood cell (RBC) transfusions in the peri-operative period - RBC transfusion may lead to improved outcome but on the other hand the intervention may be harmful - Danish Health and Medicines Authority recommends transfusion of RBC at hemoglobin below 5 mmol/L while local clinical guidelines recommend transfusion of RBC to maintain hemoglobin levels above 6 mmol/L - A large randomized clinical trial is needed to evaluate the efficacy and safety of RBC transfusion in patients undergoing vascular surgery. - A trial examining the effect of RBC transfusion on tissue oxygenation is used to test the trial-design and feasibility for a trial evaluating post-operative mortality and morbidity.
Purpose: Intracranial atherosclerosis is a common condition in Korean population consisting over 25% of ischemic stroke etiology. American Stroke Association and Korean Stroke Society recommend antiplatelet and statin for the treatment of intracranial atherosclerosis. Besides lowering blood cholesterol levels statin also stabilize atherosclerotic plaque and eventually lower the risk of ischemic stroke. However, little evidence resides on the effect of statin treatment on intracranial atherosclerosis. Recent advance in high-tesla magnetic resonance imaging enables direct imaging of intracranial atherosclerotic plaque and further assessment of treatment efficacy of statin in stabilization of intracranial atherosclerotic plaque became possible.
Longitudinal cohort study of older-aged people living with HIV infection in southwestern Uganda and age and gender-matched HIV uninfected controls with the primary aim of measuring the epidemiology of cardiovascular and pulmonary disease in this study setting, and particularly the contribution of HIV infection to it.
In a prospective international multicenter observational study, 1080 stable chest pain patients (REALITY Advanced registry of CCTA patients) with the suspected chronic coronary syndrome will be enrolled. All of them will undergo computed tomography angiography, CMR and/ or SPECT, and Echo. One of the cohorts will be examined with multimodality invasive imaging including quantitative coronary angiography, FFR, QFR with or without further percutaneous coronary intervention, OCT, and some of them - with IVUS, VH-IVUS. The plaque size and relevant stenosis, a composition of the atherosclerotic lesion, major adverse cardiovascular events (all-cause death, death from cardiac causes, myocardial infarction, or rehospitalization due to unstable or progressive angina, ischemia-driven revascularization) will be judged to be related to either originally treated (culprit) lesions or untreated (non-culprit) lesions. Moreover, the clinical potential of both non-invasive and invasive imaging, as well as anatomical vs functional modalities in two real-world patient flows, will be estimated with the special focus on the natural progression of atherosclerosis, clinical outcomes, and safety (contrast-induced nephropathy, radiocontrast-induced thyroid dysfunction, and radiation dose). The diagnostic accuracy will be analyzed. The follow-up period will achieve 12 months prospectively with collected clinical events and imaging outcomes which will be determined at the baseline and 12-month follow-up. The independent ethics expertise will be provided by the Ural State Medical University (Yekaterinburg, Russia) and Central Clinical Hospital of the Russian Academy of Sciences (Moscow, Russia). The monitoring of the clinical data with imaging as well as further CoreLab expertise (expert-level post-processing multimodal imaging software of Medis Imaging B.V., Leiden, The Netherlands) will be provided by De Haar Research Task Force, Amsterdam-Rotterdam, the Netherlands. FFR-CT is scheduled to be assessed by the ElucidVivo Research Edition software from Elucid Bio, Boston, MA, U.S.A. The REALITY project is a part of the JHWH (Jahweh) International Advanced Cardiovascular Imaging Consortium. The main objective of the Consortium that is uniting international efforts of both Academia and Industry is a synergistic development of the advanced machine-learning imaging software in order to integrate benefits of both non-invasive and invasive imaging providing the daily clinical practice with the robust tool for the anatomical and functional examination of coronary atherosclerosis, PCI-related arterial remodeling, and relevant myocardial function.
Classification of carotid plaque vessel wall changes in carotid stenosis accordingly to AHA classification (American Heart Association)- comparison between histology and CT. The CT is performed with a fast kVp-switching dual energy technique. To compare the ability to detect iodine contrast enhancement in the carotid plaque compared with 3T MRI with gadolinium.
The investigators tested if a nutraceutical combination with red yeast rice, berberine and policosanol (NC) can significantly modify inflammation, lipid profile and markers of endothelial injury (endothelial microparticles) in subjects with elevated levels of high-sensitivity C-reactive protein (hsCRP).
The purpose of this study is to determine whether Rosuvastatin 10mg/d or 20mg/d for 36 weeks can regress critical coronary atherosclerosis as determined by IVUS imaging in Chinese Acute Coronary Syndrome (ACS) patients.
To demonstrate feasibility of imaging Cu[64]-25%-CANF-Comb uptake in the atherosclerosis of the carotid artery of patients for whom carotid artery endarterectomy surgery is planned in comparison to the carotid artery for which intervention is not planned.
