Filter by:This is a multi-national, multi-centre, randomized study comparing the trans-radial PCI access strategy and the trans-femoral PCI access strategy in ACS patients with UA or NSTEMI or STEMI planned to be treated with an invasive strategy (PCI). The hypothesis is that radial access site PCI will be associated with significantly less major bleeding and access site complications compared with a femoral approach, without increasing the risk of ischemic events. The overall benefit-risk profile will favor a trans-radial approach.
The purpose of this randomized, multi-site, clinical trial is to determine whether intensive therapy consisting of cholesterol-lowering statin drugs plus apheresis to cleanse the blood of low-density lipoprotein (LDL) cholesterol is more effective than statin therapy alone in reducing plaque volume in heart arteries of patients who have already suffered an acute coronary syndrome (ACS). The study will also investigate whether this intensive approach can help increase the presence of endothelial progenitor cells (EPC), stem cells that have been shown to reduce cardiovascular (CV) events in ACS patients. This study has II phases and FDA approval for phase II has been received.
To investigate the biosynthesis of PGD2 during percutaneous transluminal coronary angioplasty (PTCA) procedure.
This study will test whether darapladib can safely lower the chances of having a cardiovascular event (such as a heart attack or urgent coronary revascularization (e.g. medical procedures performed to restore the normal blood flow in patients with atherosclerosis)) when treatment is started within 30 days after an acute coronary syndrome (also called ACS).
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
Emotional states of depression in association with ischemic heart diseases, such as myocardial infarction or unstable angina, are risk factors for subsequent cardiac events and mortality. However, the only psychological intervention trial attempting to reduce cardiac risk in depressed ACS patients showed that changes in depression did not translate into improved survival. Such intervention did not address issues such as lifestyle modification and improvement in psychological well-being, which were found to affect individual vulnerability to medical disease. Our research group has developed a well-being enhancing psychotherapeutic strategy, well-being therapy (WBT), which has been validated in a number of clinical trials. The aim of this project is to evaluate the efficacy of cognitive behavioral treatment (CBT) together with lifestyle modification and WBT in reducing cardiac risk in depressed and/or demoralized ACS patients compared to a standard clinical procedure of patients' management, the clinical management (CM). The same protocol will be carried out in two centres (Bologna and Torino). 100 patients after a first episode of myocardial infarction or unstable angina, meeting DSM-IV criteria for depressive disorders and DCPR criteria for demoralization will be randomized to one of two treatment groups: 1) CBT supplemented by lifestyle modification and WBT; 2) CM. In both groups, treatment will consist of twelve, 45-minute sessions once a week. A two-year follow-up will be performed. It is expected that psychological treatment may significantly decrease cardiac morbidity and mortality at follow-up compared to clinical management. The findings may entail considerable preventive implications and possible large reductions in health costs.
The purpose of this study is to determine whether nonsteroidal antiinflammatory drug lornoxicam in combination with low dose aspirin (100mg/day) is effective and safe in patients with Acute Coronary Syndrome without persistent ST-segment elevation.
The purpose of this study is to evaluate the safety and efficacy of various doses of YM150 (the experimental drug) in the prevention of ischemic vascular events in subjects with recent acute coronary syndromes.
The goal of this research is to determine noninvasively whether detection of coronary stenosis and plaque by multidetector computed tomography (MDCT) in patients with acute chest pain suspected of acute coronary syndrome (ACS) enhances triage, reduces cost and is cost effective. Among the 5.6 million patients with ACP presenting annually in emergency departments (ED) in the United States, a subgroup of two million patients is hospitalized despite normal initial cardiac biomarker tests and electrocardiogram (ECG). This subgroup is at low (20%) risk for ACS during the index hospitalization. Most (80-94%) patients with a diagnosis of ACS have a significant epicardial coronary artery stenosis ( >50% luminal narrowing). However, in -10% of patients non-stenotic coronary plaque triggers events, i.e. vasospasms, leading to myocardial ischemia. Since the absence of plaque excludes a coronary cause of chest pain, these patients could in theory be discharged earlier reducing unnecessary hospital admissions. Recent publications demonstrate high sensitivity and specificity of MDCT for the detection of significant coronary stenosis compared with coronary angiography and the detection of coronary plaque as validated with intravascular ultrasound. Using 64- slice MDCT we propose to study 400 patients with ACP, negative initial cardiac biomarkers and non-diagnostic ECG. We will analyze MDCT images for the presence of significant coronary artery stenosis and plaque and correlate the data with the clinical diagnosis of ACS (AHA guidelines) during the index hospitalization to determine the sensitivity and specificity. MDCT data, risk factors, and the results of standard diagnostic tests available at the time of MDCT will be used to generate a multivariate prediction function and derive a clinical decision rule. Based on this decision rule we will compare the diagnostic accuracies and cost effectiveness of competing strategies. We hypothesize that an MDCT- based diagnostic strategy will reduce the time to diagnosis of ACS, number of hospitalizations, and absolute cost of management of patients with acute chest pain compared to standard clinical care and is cost effective.
Continuing to smoke after having a heart attack greatly increases the risk of death and cardiac illness. The nicotine patch is a commonly used pharmacotherapy for smoking cessation and has great potential to help heart attack patients quit smoking. However, due to safety concerns, physicians are often hesitant to prescribe the nicotine patch to patients who have just suffered a heart attack. The STADIA pilot study will assess the feasibility of a large-scale clinical trial investigating safety and efficacy outcomes associated with the nicotine patch immediately following a heart attack. Eligible subjects will be randomized within 48 hours of suffering a heart attack to wear a transdermal nicotine patch on either day 1 or day 2 of the study period. The nicotine patch will deliver nicotine to the patient over the period of 24 hours. Patients will be advised to discuss smoking cessation strategies with their treating physician and subsequent care will be left to the discretion of this physician. The duration of ischemia (loss of blood flow in the heart), patient adherence, incidence of arrhythmia (disorder of the heart rate or rhythm), heart rate, and blood pressure within the two groups will be used to evaluate the safety of transdermal nicotine use immediately after a heart attack.
