Filter by:The investigators will generate pressure-flow loops and pressure-volume loops from aortic and left ventricular pressure waveforms and Doppler (desc. aorta) flow waveforms and compare left ventricular to arterial pressure-flow and pressure-volume loops as well as to cardiac power from the USCOM 1A device. The goal of this study is to test the hypothesis that non-invasive estimates of cardiac pressure-volume work (derived from ultrasound-based measurements) correlate with invasive estimates.
The purpose of this study is to assess the effect of stearidonic acid when used as a food ingredient on eicosapentaenoic enrichment of red blood cell membranes and Omega-3 Index in men and women.
The purpose of this study is to test the hypothesis that the intracoronary transplantation of autologous mononuclear and CD 133 + bone marrow cells will improve left ventricular contractile function and will reduce the combined end points after the primary STEMI (mortality, recurrent myocardial infarction, angina, heart failure, stroke).
To evaluate the efficacy of combination therapy with ranibizumab (RBZ) and panretinal photocoagulation (PRP) versus PRP alone in patients with treatment-naive bilateral proliferative diabetic retinopathy (PDR) as measured by mean change in visual acuity (VA), mean change in central retinal thickness (CRT) as measured by time-domain optic coherence tomography (TD-OCT) and incidence of vitreous hemorrhage (VH).
Patients on hemodialysis (HD) exhibit an immensely increased cardiovascular mortality associated with extensive vascular calcification (VC). In the past years the development of VC was discovered to be actively regulated and as being influenced by inhibitors of calcification (e.g. matrix-Gla-protein, fetuin-A). MGP is produced by vascular smooth muscle cells and needs post-translational modification by vitamin K dependent gamma-carboxylation to be fully active. Based on the demonstration of increased PIVKA-II levels, about 97% of all HD patients exhibit insufficient carboxylation activity. We therefore aim in this randomized, controlled study to retard the progress of coronary and aortal calcification as assessed by thoracic multislice-CT by the thrice weekly administration of 5 mg vitamin K1 (phylloquinone) to about 100 HD patients over a period of 18 months.
Early interventions to promote physical activity, dietary lifestyle changes and optimal medication for cardiovascular risk factor reduction - 3 years follow-up. A randomized Clinical Trial.
To assess the clinical value of iFR to characterize, without concomitant administration of hyperemic agents and outside a specified range of iFR values, coronary stenosis severity as determined with fractional flow reserve (FFR)
The objective of this study is to explore the relationship between the ClearView scan results and a variety of cardiovascular risk indicators such as the Coronary Calcium Score, Framingham Risk Factors, Reynolds Risk Score, and biomarkers of inflammation. The ClearView device is a bio-electrographic tool that may assist medical professionals in rapid assessment of the systemic origin of the patient's presenting symptom(s). The ClearView is a potentially valuable resource that may benefit a physician's office by offering expedited differentiation capabilities. The subsequent results have the potential to include more data that would allow rapid patient diagnosis, triage, and treatment; optimized precious resource expenditure (nursing, physician, etc.); lower costs to facility, patient and insurance company; and decreased office wait time.
The goal of this study is to examine if chronic cherry consumption will decrease lipid peroxidation and serum concentration of inflammatory markers in human subjects with elevated serum C reactive protein (CRP), and to examine the relationship between serum concentrations of CRP and polyphenols. The investigators hypothesize that cherry consumption will reduce serum concentration of inflammatory markers, including CRP, inflammatory cytokines and adhesion molecules.
Adult survivors of childhood cancer are at high risk of developing cardiovascular disease. Therapies used to treat many cancers, such as chemotherapy and radiation, likely cause damage to the surface of the artery wall called the endothelial layer, leading to the induction of atherosclerosis and eventual cardiovascular disease. HMG coenzyme A reductase inhibitors, or statins, improve endothelial function independent of cholesterol-lowering. In addition, statins have been shown to reduce arterial stiffness and slow arterial thickening. Despite strong evidence supporting the vascular benefits of statins in many different patient populations, these medications have never been studied in cancer survivors. Therefore, the overall objective of this study is to evaluate the effects of statin therapy on vascular health in young adult survivors of childhood cancer. Twenty-four young adult (age 18-39 years old) survivors of childhood acute lymphoblastic leukemia (ALL) or non-Hodgkin's lymphoma (NHL) will be enrolled in a six-month randomized, double-blind (participants and investigators), placebo-controlled pilot clinical trial comparing the effects of atorvastatin versus placebo on endothelial function and other measures of vascular health. Our primary objective is to evaluate the effects of 6-months of statin therapy on conduit artery endothelial function in young adult survivors of childhood cancer. The investigators hypothesize that, compared to placebo, atorvastatin will significantly increase brachial artery flow-mediated dilation in survivors of childhood acute lymphoblastic leukemia and non-Hodgkin's lymphoma.
