Filter by:This double-blind, parallel, two-arm study will evaluate the potential to reduce cardiovascular risk, the tolerability and long-term safety profile of aleglitazar compared to placebo on top of standard care in patients with recent acute coronary syndrome (ACS) and type 2 diabetes mellitus. Patients will be randomized to receive either aleglitazar or placebo once daily as oral doses. The study will last until at least 950 events occur, but time on study treatment will be for at least 2.5 years.
Clinical decision units (CDUs) improve resource utilization and are a recommended care option by the American College of Cardiology / American Heart Association, but are underutilized in non-low risk chest pain patients due to weaknesses of traditional cardiac testing. Cardiac magnetic resonance imaging (CMR) is sensitive and specific for ischemia, can simultaneously assess cardiac function and myocardial perfusion, and could revolutionize the diagnostic process for intermediate risk patients with chest pain. The primary objective of this trial is to measure the efficiency and safety of a combined CDU-CMR care pathway compared to inpatient care among patients with non-low risk acute chest pain.
Patients will be consented and screened within 2 to 6 months of the index ACS. Patients who have elevated depression (BDI>=15 or BDI>=10 assessed twice over two week period) and who continue to meet all of the trial's eligibility criteria will be consented. Through informed consent, both arms of the trial will be described with equipoise as to these approaches to postACS depression care. Patients who consent to randomization will be enrolled in the treatment trial. The intervention phase will be 6 months, and hence the final outcome assessments will be performed approximately 9 months after the index ACS. Interim measures of depression will be obtained at 2 and 4 months post-enrollment. Major adverse cardiac events and all-cause mortality will also be ascertained at 6 months post-enrollment. Quality assurance by an independent medical event adjudication committee using prospective guidelines will be employed.
The purpose of this study is to compare women's cardiac rehabilitation program adherence across three program models.
Instead of treating in-stent restenosis, the best strategy for patients is preventing in-stent restenosis. Recent advances in the understanding of the cellular mechanism responsible for smooth muscle cell proliferation (neointimal hyperplasia), together with improvement in stent coating and eluting technology have provided the scientific background to develop drug eluting stents. Drug eluting stents (DES) are now the most promising development in interventional cardiology. Different classes of drugs mounted in a polymer layer on the surface of the stent have shown to be very effective in preventing neointimal hyperplasia. Currently there are 7 DES stents CE marked and commercially available on the market. Two stents, respectively the sirolimus eluting Cypher™ stent and the paclitaxel eluting Taxus™ stent, are in clinical use since 2002. The Cypher™ stent consists of the Bx sonic stent/balloon platform. The stent is coated with a non-degradable biocompatible PBMA/PEVA polymer which elutes sirolimius. The Taxus™ stent consists of the Express2 balloon/stent platform coated with non-degradable biocompatible Translute™ polymer which elutes paclitaxel. Recent large randomized trials like RAVEL, SIRIUS, E-SIRIUS C-SIRIUS (Cypher™ versus bare metal BX sonic™ stent), TAXUS II, IV, V, VI (Taxus versus bare metal Express™ stent) have shown that DES dramatically reduce the incidence of in-stent restenosis and subsequently the need for target lesion revascularization in patients with non complex and moderate long de-novo coronary lesions in vessels with a diameter between 2.5 -3.5 mm.1-11 Considering the very encouraging results of these early clinical trials with so far mid long term follow-up, there is the need to explore the utilization of DES in the other subsets of coronary lesions like: long lesions, chronic total occlusions, venous graft lesions, thrombotic lesions, restenosis lesions, ostial and bifurcation lesions and lesions in large vessels. As the result from the previous reported randomized trials, FDA and other regulatory institutes require that new DES are now being evaluated against one of the former DES (Cypher or Taxus). The XIENCE-V stent is a second generation DES, with thinner and more flexible Cobalt-Chromium stent struts, compared to the first generation Stainless Steel stent struts of Cypher and Taxus. This study addresses the questions whether the XIENCE-V™ stent has superior clinical results as the Taxus™ stent in the general population that is being referred for percutaneous coronary intervention (PCI). Objective of the study: The main objective of the study is a head tot head comparison of the everolimus coated XIENCE-V™ stent with the paclitaxel coated TAXUS™ stent in order to observe whether there is a difference in clinical outcome between both stents. Efficacy of both stents will be assessed by the composite end point of: all death, non fatal myocardial infarction and target vessel revascularization. Study design: Single center, randomised, open label study in all-comers referred for PCI. Study population: Approximately 1600 consecutive patients with coronary artery disease who are eligible according to the in- and exclusion criteria will be enrolled and randomized on a 1:1 basis. Primary study parameters/outcome of the study: The primary end point of the study is the composite end point of: all death, non fatal myocardial infarction, target vessel revascularization at 1 year. Secondary study parameters/outcome of the study: The secondary end points of the study are: A) The combined endpoint of cardiac death, non fatal myocardial infarction, ischemic driven target lesion revascularization (TLR) rate at 1, 6 and 12 months follow-up. B) The combined endpoint of all death, non fatal myocardial infarction, target vessel revascularization (TVR) rate at 2, 3, 4 and 5 years. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The burden for the patient consists of filling in 8 questionnaires (1 A4 per questionnaire) in 5 years time. The first 3 questionnaires in the first year are also requested for monitoring purposes by the Ministry of Health and the Dutch Cardiology Society (Nederlandse Vereniging Voor Cardiologie; NVVC). There is no risk for the patient related to participation in this study. The patient will receive a Taxus or Xience-V stent anyhow, if the indication for a DES stent exists.
The purpose of this trial is to investigate the potential benefits/risks regarding pretreatment with prasugrel in non-ST-elevation myocardial infarction (NSTEMI) participants with elevated troponin scheduled for coronary angiography/percutaneous coronary intervention (PCI).
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.
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).
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.
