Filter by:The International Registry of Acute Coronary Syndromes registry study in Transitional Countries (ISACS-TC) is both a retrospective and prospective study which was designed in order to obtain data of patients with acute coronary syndromes, and herewith control and optimize internationally guideline-recommended therapies in these countries Further study details as provided by the CINECA http://isacs-ct.cineca.org/
The NET-SCA Registry has been designed to document and evaluate the clinical epidemiology and current management of Acute Coronary Syndromes in the Lazio Region of Italy.
Chronic kidney disease (CKD) affects 10-18% of the adult population and is becoming recognized as one of the most serious disorders causing increased risk for cardiovascular disease and death. In patients with ischemic heart disease 26% have increased creatinine, which rises to 40% if patients also have diabetes mellitus. Risk increases as renal function diminishes, and just slowing the rate of decline in renal function would have a tremendous impact on health and morbidity. This association is commonly termed the Cardiorenal Syndrome, though it is caused by a much more complex interplay between major pathogenetic pathways such as glucose metabolism and diabetes, systemic and tissue inflammation, tissue metabolism, coagulation, mineral metabolism, sympathetic activation, renin-angiotensin-aldosterone system activation, endothelial dysfunction, lipid metabolism, fetal programming etc. Karolinska Institutet recently merged basic and clinical researchers in all these fields, creating a Karolinska Kardiorenal Theme Centre; ultimately aiming to explore the syndrome and provide improved care for the individual patient. The investigators road to success: - Creating a Biobank (blood, DNA, plasma) from the majority of all hosptalized patients with ACS in Stockholm county - Stockholmheartbank. - This Theme Center include all teaching hospitals associated with Karolinska Institutet; Danderyd University Hospital, Karolinska University Hospital and Södersjukhuset University Hospital. Together theses hospitals serve as emergency hospitals for 1.9 million people. The investigators are aiming at creating a biobank from all patients admitted for an acute coronary event (about 2.300/yr), which is a unique asset for molecular and genetic research as well as observational and intervention studies. - The investigators have access to the National registry with 100% coverage, that contains data on all patients admitted to Stockholms coronary care units since 1995. - To ensure translation in to clinical practice, most of the researchers are also MD:s, and several are clinically active. - The clinical network facilitates the development of novel therapies and translational research. - Steering groups for Education and a Clinical Practice implementation program.
Assess the role of a nicotine antagonist in helping patients presenting to hospital with acute coronary syndrome to stop smoking.
Background: Both prasugrel and clopidogrel are prescribed drugs which compete as platelet inhibitors in patients with acute coronary syndrome (ACS). Whether rates of drug resistance/hyporesponsiveness are lower with prasugrel and whether more consistent and earlier onset of platelet inhibition may reduce infarct size in patients with ACS undergoing early PCI remains, at present, unknown. Study design/study population: This trial is a prospective, open-label, single centre observational trial. Patients receive either prasugrel (60mg) or clopidogrel (600mg) at the discretion of the attending cardiologist. Patients with exclusion criteria for prasugrel will be excluded for clopidogrel as well. The study population includes 80 subjects with moderate to high-risk ACS, ie patients with unstable angina (UA) and non-ST-segment elevation MI (NSTEMI) and TIMI risk score of 3 or higher, within 72 hours after onset of symptoms. In all patients early PCI is planned. Study objective/endpoint/methods: The primary objective of this trial is to evaluate whether rates of hyporesponsiveness are lower with prasugrel and whether more consistent and earlier onset of platelet inhibition may reduce infarct size in ACS in patients undergoing early PCI. The primary endpoint is the rate of drug resistance at time of index intervention. Optical and impedance aggregometry using ADP (5 and 20 μM) and collagen (1 μg/ml) as platelet agonists is used to measure platelet aggregation. Addition of the specific antagonists aspirin and mesamp to the probe is used to discriminate between pharmacodynamic and pharmacokinetic drug resistance. Secondary endpoint is the reduction of myocardial infarct size determined by post-interventional increase of high sensitive TnT (TnT hs) during the days following the index event reflecting earlier, more effective and more consistent inhibition of platelet function. Tertiary endpoint is the composite clinical endpoint of cardiovascular death, nonfatal MI, or stroke and urgent target vessel revascularization during hospitalization and after 6 and 12 months. Safety endpoint is any TIMI major or minor bleeding during hospital stay and after 6 and 12 months including intracranial and life-threatening bleeding.
The purpose of this study is to assess the effects of Ezetimibe on coronary plaque volume in patients with acute coronary syndrome.
PCI has been one of the most common choice of treatments for patients with coronary artery disease, and studies indicated that intensive statin treatment before PCI could reduce adverse events as comparing to the placebo. In China, statin with regular dose is currently applied to the patients admitted for Non-ST-elevation acute coronary syndrome (ACS). Here we hypothesize that intensive statin treatment with arovastatin before PCI could further reduce clinical adverse events.
The investigators will make a prospective study in which they will look at the economics and security of the treatment of patients with acute coronary syndrome. The investigators want to do a randomized trial. One group will be treated as they have been treated at Ullevål University Hospital (UUS) in recent years, and the other group will be returned to their refering hospital the same day. The objective of this study will be to provide increased knowledge about whether the rapid discharge from the intervention center is associated with differences in costs or security.
Subproject 1: Optimize prevention after acute coronary syndromes (ACS) by improving caregiver and patient education (http://elips.hug-ge.ch/eng/index_eng2.htm) Subproject 2: Discover novel genomic biomarkers of ACS in leukocyte subsets by means of analyzing gene expression profiles and function Subproject 3: Evaluate novel diagnostic and prognostic biomarkers in soluble form in blood/plasma and urine Subproject 5: Visualize the vulnerable plaque using intravascular ultrasound/optical coherence tomography (IVUS/OCT) and correlate with outcome and biomarkers Subproject 7: Characterize the effects of inflammation on progenitor/stem cell-mediated repair after ACS by means of analyzing gene expression profiles and function
A pilot, prospective, comparative study. To include both male and female patients who have presented an ischaemic stroke (full stroke or TIA) or an ACS, 5 to 30 days prior to inclusion. The proposed study aims to investigate and analyse the differences in functional and structural arterial properties between the patients who presented an ischaemic stroke and those who presented ACS. The hypothesis is that the patients in both groups will present differences partly in terms of their "traditional" cardiovascular risk factors, but also in terms of their arterial properties. All of the confounding factors studied (cardiovascular risk factors, treatments) will be taken into account in order to explain the differences in the arterial properties found between the two groups. Furthermore, the prevalence of signs and symptoms in the two populations will be studied.
