Filter by:Coronary angiogram (CA) procedures, with and without angioplasty, can be performed via vascular access in the wrist (radial artery) or leg (femoral artery). Both radial and femoral artery vascular access have their advantages and disadvantages, but neither has yet been proven to have superior health outcomes. Often patients are eligible for both access sites but are not well informed regarding the potential advantages and disadvantages of each site. Vascular access in cardiac catheterization can be considered a "grey zone", where the benefits and harms may have different levels of significance depending on the individual's preferences and values. For example, patients with significant back pain may not prefer the femoral approach as it requires the patient to lie flay for an extended period of time compared to the radial approach. For "grey zone" health care options, Patient Decision Aids (PtDA) have been demonstrated to improve the quality of decision making by significantly improving knowledge of the patient's health care options, improving the patient's accurate risk perception, and improving value congruence with the chosen options. The investigators propose a randomized controlled trial (RCT) to evaluate the decision quality impact of a vascular access PtDA compared to "usual care" in eligible patient's undergoing elective CA procedures. If the PtDA is demonstrated to positively impact the decision quality of patients prior to CA procedures, it would be an invaluable bedside tool to promote patient informed medical decision making. Hypothesis: The investigators believe that a PtDA, when compared to usual care, will positively impact the decision quality and the process of decision making, relating to vascular access options in eligible patients undergoing elective CA procedures.
Vascular inflammation is a key factor in both the pathogenesis and outcome of atherosclerosis. Various inflammatory markers such as LpPLA2,MCP-2 and hsCRP are well-known prognostic factors for the cardiovascular event. 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) is a promising tool for identifying and quantifying vascular inflammation within atherosclerotic plaques.Therefore, the purpose of the study is to demonstrate the correlation between various inflammatory markers and vascular inflammation detected by 18FDG-PET.
The present study constitutes a study examining the effect of atorvastatin on vascular function in high cardiovascular risk patients. For this purpose the investigators will record atorvastatin effects on statin-naïve patients (patients that start statins treatment for first time). More specifically the investigators will study atorvastatin effects on: 1. Endothelial function 2. Arterial elastic properties 3. Systemic Inflammatory/thrombotic mechanisms 4. Vascular and myocardial redox state
Vitamin D is a fat-soluble vitamin that is naturally present in very few foods, added to others, and available as a dietary supplement. It is also produced in the body when ultraviolet rays from sunlight strike the skin and trigger vitamin D synthesis. Vitamin D is essential for promoting calcium absorption and maintaining adequate serum calcium and phosphate concentrations to enable normal mineralization of bone and bone growth. Without sufficient vitamin D, bones can become thin, brittle, or misshapen. Vitamin D sufficiency prevents rickets in children and osteomalacia in adults. Together with calcium, vitamin D also helps protect older adults from osteoporosis. Many people have low levels of Vitamin D. Replacing Vitamin D is thought to help lower the risk of heart disease. Vitamin D may be helpful, but it could also be harmful. The investigators are studying the effect of Vitamin D on the level of a harmful kind of cholesterol. Participants will have their cholesterol levels measured and then receive either Vitamin D or a placebo. After 2 months of treatment, the investigators will measure their cholesterol levels again.
The purpose of this study is to determine plasma levels of paclitaxel and catheter tolerability subsequent to treating patients with peripheral arterial occlusive disease (PAOD) with paclitaxel-coated balloon catheters.
The present project is aimed at determining the prevalence of LDL-C <130 mg/dl with hsCRP ≥2mg/l, and of HDL-C < 40 mg/dl in Spain together with the estimation of cardiovascular risk, to analyze the contribution of measuring hsCRP for primary prevention purposes. In a subgroup of that population a number of inflammatory and oxidative status biomarkers would be also measured to better understand the meaning of elevated hsCRP.The study aim to analyze data already collected in studies (11 studies will participate) carried out in Spain, in 10 Spanish regions, after the year 2000.
This study will evaluate the effect of ACZ885 on vascular function in patients with documented atherosclerotic disease and T2DM or IGT.
The purpose of this study is to investigate the link between rheumatoid arthritis and cardiovascular disease by studying inflammation, joint disease, cholesterol abnormalities, and endothelial function.
This observational study looks at Carotid Stenosis in two groups of subjects using a non-invasive procedure, B-mode ultrasound. One group of subjects has had long-term intensive lipid altering therapy (lowering LDL-C plus raising HDL-C). The second group of patients has been on conventional "standard of care" treatment for carotid stenosis. The study will look at the Carotid Intima-media Thickness (CMIT) in both groups. Hypothesis: CIMT will differ between the two groups, such that the CIMT will be less in the subjects on intensive lipid altering therapy.
This study will evaluate the effectiveness of an individualized approach to diagnosing and/or treating atherosclerosis. This will be done by combining genetic information, lifestyle information, participant education, and imaging tests to track diagnoses, therapies, and treatment on two groups: 1) Standard Management Group (diagnosed and/or treated according to standard of care) and 2) Individualized Management Group (standard of care plus genetic testing and coronary artery calcium scans).
