Filter by:This randomized trial will assess the efficacy of Drug Coated Balloon (DCB) compared to Bare Metal Stent (BMS) using Fractional Flow Reserve (FFR) guidance for de novo coronary artery lesions in patients unable to tolerate dual antiplatelet therapy and at high risk of bleeding. Patients will be randomized after balloon angioplasty to receive either DCB or BMS. Endpoints are late luminal loss at 9 months, and major adverse cardiac events including arterial thrombosis at 1, 9 and 12 months.
The purpose of the Patient and Provider Assessment of Lipid Management Registry (PALM) is to gain a better understanding of physicians' cholesterol medication prescribing practices, patient and physician attitudes and beliefs related to cholesterol management, and current utilization of cholesterol-lowering therapies given the new ACC/AHA guideline recommendations. The PALM Registry hopes to allow for the design of ways to improve cholesterol management and decrease the burden of cardiovascular disease (CVD) in the US.
A randomized controlled, open label, multicenter trial with 1000 patients aged 70 years and older, presenting with Non-ST-elevation acute coronary syndrome. Patients will be randomized to either clopidogrel or the novel P2Y12 inhibitor (ticagrelor or prasugrel). Patients will be followed for one year for outcomes such as bleeding episode requiring medical intervention and net clinical benefit (all cause mortality, non-fatal myocardial infarction, non-fatal stroke, PLATO major and minor bleeding).
Specific cardiovascular diseases, such as stroke and heart attack, have been shown to vary by ethnic group. However, less is known about differences between ethnic groups and a wider range of cardiovascular diseases. This study will examine differences between ethnic groups (White, Black, South Asian and Mixed/Other) and first lifetime presentation of twelve different cardiovascular diseases. This information may help to predict the onset of cardiovascular diseases and inform disease prevention strategies. The hypothesis is that different ethnic groups have differing associations with the range of cardiovascular diseases studied.
To evaluate the safety, performance and efficacy of the bioresorbable vascular scaffold (BVS) system in patients with coronary artery disease
The purpose of this study is to collect additional safety and effectiveness data for on the Biosensors BioFreedom™ BA9 Drug Coated Coronary Stent in patients with native, de novo coronary artery disease.
The objective of this study is to evaluate CMX-2043 for prevention of renal and cardiac injury associated with coronary angiography in patients with acute coronary syndrome (ACS), but excluding ST-elevation myocardial infarction (STEMI) patients. This study will specifically examine the ability of CMX-2043 to prevent acute renal injury following coronary angiography. The study will also examine the ability of CMX 2043 for prevention of periprocedural cardiac injury. Information will be obtained relating to the ability of CMX 2043 for prevention of major adverse cardiac and renal events following the procedure. Additional information will be obtained in this study to evaluate safety of the drug. Dose and regimen information will also be obtained for future clinical studies of CMX-2043.
High density lipoprotein cholesterol (HDL-C) is in the centrum of the process of reverse cholesterol transport from peripheral cells to the liver[10]. HDL-C promotes endothelial generation of nitric oxide (NO) and improves endothelial function and arterial vasoreactivity[11]. In several studies, lower HDL-C level was reported to be associated with increased coronary artery disease (CAD) risk[12-14]. HDL-C also has anti- inflammatory and anti-oxidant activities[15,16]. Concerning anti-inflammatory activity, HDL-C inhibits the activation of monocytes/macrophages and neutrophils[17,18] and inhibits the expression of endothelial adhesion molecules, such as vascular cell adhesion molecule-1 (VCAM-1) and E-selectin[15]. In this study we aimed to investigate the relation of HDL-C level with systemic inflammatory markers in patients with cardiac syndrome X (CSX).
The purpose of this study is to evaluate the effect of vitamin E on preventing from incidence of contrast induced acute kidney injury (CI-AKI) in the patients who undergone coronary angiography.
Autoimmune diseases are diseases in which inappropriate immune responses that have the capability of harming host cells play an important role. Evidence suggests that the presence of certain autoimmune diseases such as rheumatoid arthritis or systematic lupus erythematosus increase the risk of cardiovascular disease (CVD). However, this evidence is inconsistent for autoimmune disorders and no systematic approach has been previously used to study the relationship between a range of common autoimmune disorders and specific forms of cardiovascular diseases such as myocardial infarction, intracerebral and subarachnoid haemorrhage, or venous thrombosis. The investigators will use linked electronic health records to investigate whether commonly diagnosed autoimmune disorders are associated with increased risk of CVD development and whether effects differ in men and women and change with age.
