Filter by:The purpose of this registry is to compare the safety and the performance of the NEVO™ Sirolimus-eluting Coronary Stent, once commercially available, to the CYPHER Select® Plus Sirolimus-eluting Coronary Stent in complex subjects presenting with acute STEMI for primary intervention, diabetes mellitus or multi vessel disease. The second purpose of this registry is to evaluate the safety and performance of the NEVO™ Sirolimus-eluting Coronary Stent, once commercially available and the CYPHER Select® Plus Sirolimus-eluting Coronary Stent in complex subjects diagnosed with acute STEMI for primary intervention, diabetes mellitus and/or multi vessel disease. The data will be collected from subjects treated with commercially available product and following routine clinical practice. Uniform, complete and accurate data will be collected on the subject's medical history, peri-procedurally, during the index hospitalization, and during follow-up.
The aim of this study is to identify patients with problem list gaps and intervene to correct these gaps by creating clinical decision support interventions that alert providers to likely problem list gaps and offer clinicians the opportunity to correct them. The investigators will randomize the clinics that will receive the intervention and formally evaluate the study after a period of 6 months for improved problem list completeness to determine the effectiveness of our intervention.
- The purpose of this study is to determine the level of inhibition of platelet activation of an approved thienopyridine(clopidogrel or prasugrel) and aspirin regimen in the setting of drug eluting coronary stent implantation. - In subjects with high residual levels of platelet reactivity after receiving either a maintenance or loading dose of either clopidogrel or prasugrel, a cross over of thienopyridine treatment to the alternate medication will occur. - The study tests the hypothesis that adequate platelet inhibition will occur in subjects who have high levels of platelet reactivity and are subsequently switched from clopidogrel to prasugrel(loading or maintenance dose) without increased episodes of bleeding or MACE events at discharge and 30 days post Percutaneous Coronary Intervention (PCI).
This study will explore the effect of different doses of aspirin on the effects of double-dose or standard dose clopidogrel.
Does tomato extract improve blood vessel function in healthy people and people with cardiovascular disease? Atherosclerosis ('furring' of the arteries) affects the functioning of blood vessels, narrowing and eventually blocking them, causing conditions like heart attack and stroke. The Mediterranean diet, which is rich in tomatoes and tomato-based products, has been shown to be associated with a reduced risk of blood vessel damage. In this double blind, placebo-controlled randomised study, the investigators will investigate whether a food supplement containing a standardised extract of tomato improves blood vessel function in both healthy people (aged 40-80), and people with a history of cardiovascular disease. The food supplement is on sale to the public, and the investigators are testing the standard dose. Approximately 72 people will take part at the Clinical Pharmacology Unit at the ACCI Building, Cambridge University Hospitals NHS Trust. After they have passed screening tests, participants will be allocated by chance to receive either the tomato extract product (Ateronon), or a matching placebo (a dummy capsule with no active ingredients), which they will take once a day for 8 weeks. At the beginning and end of the treatment period, the investigators will test blood vessel stiffness using an ECG machine and external probe. The investigators will also measure forearm blood flow, which involves infusing 3 separate agents that affect how the lining of the blood vessel wall works, and helps to assess whether this is affected by the study treatment. Blood tests will also be used to look at how the food supplement is working and its effects on cholesterol and markers of inflammation. Including the screening period, and a follow-up telephone call two weeks after the end of treatment, participants will be in the study for 14 weeks.
Numerous human cardiac stem cell studies have been published, including relatively small number of patients. Meta-analysis of randomized trials have reported safety and a 3-6% increase in global left ventricular performance after intracoronary stem cell therapy in patients with acute myocardial infarction. Since most of the studies used different type of stem cells, delivery modes, and patient population, the results are heterogenous, therefore the comparison of the results is biased regarding generalizable conclusions about the effect of treatment. The present comparative meta-analysis is based on individual patient data, and gathers and pools the raw data, and analyzes the clinical outcome, safety and efficacy of the cardiac stem cell therapy.
The objective of the study is to assess the superiority of the biodegradable polymer based limus-eluting stent (Nobori®) compared with the permanent polymer based everolimus-eluting stent (XIENCE V®) regarding absolute percentage of uncovered stent strut segments.
Clopidogrel, an inhibitor of ADP induced platelet aggregation and activation, is one of the most commonly used drugs in patients with cardiovascular disease. The specific aim of the proposed study is to determine whether the interaction between proton-pump inhibitors (PPIs) and clopidogrel is dependent on CYP2C19 haplotype.
The objective of this study is to evaluate the security issues and efficacy of coronary stenting Cobalt Chrome covered with sirolimus-eluting Cobalt Chrome platform in patients with coronary artery lesion.
Atherosclerotic coronary heart disease is a condition thought to involve low-grade inflammation. Several reports, clinical and epidemiological, have demonstrated that intake of fish oil may be beneficial in attenuating the inflammatory process. Still, however, there are lacking data in respect to whether differences in composition of various marine oils may influence the inflammatory status differently. The hypothesis of the current study is that extract from the antarctic krill (Euphausia superba) is better than traditional fish oils when compared head-to-head with balanced composition of omega 3 content on inflammatory status.
