Filter by:The purpose of this trial is to evaluate safety and efficacy of a pericardial adipose pedicle transposition (adiFLAP) for the improvement of cardiac function in patients with a chronic myocardial infarct. Preclinical studies in the porcine model of myocardial infarction have shown that AdiFLAP reduces infarct area.
The purpose of this study is to evaluate the feasibility, efficacy, and safety of autologous transplantation of ex vivo expanded bone marrow stromal cells (BMSCs)and endothelial progenitor cells (EPCs) for treatment of patients with ischemic stroke.
The LAST study is a Norwegian multi site randomised controlled trial that intends to assess the effect of a long term follow up program after stroke. The program consists of a coordinating physiotherapist who will encourage and motivate included patients to perform at least 60 minutes of intensive motor training every week and 30 minutes of physical activity every day for 18 months after inclusion. The primary hypothesis is that patients receiving a long term follow up program after stroke will have better motor function at end of follow up than patients receiving standard care. A total of 390 home dwelling stroke patients living in the municipality of Trondheim, Asker and Bærum will be included at the out-patient clinic at St. Olavs Hospital or Bærum Hospital three months after their stroke. Included patients will be randomised to an intervention group receiving the long term follow up program or to a control group receiving standard care. Motor function, mental health and physical functioning in daily life will be assessed at inclusion and 18 months later. The LAST study is funded by the Norwegian Research Council, the Norwegian University of Science and Technology and the Central Norway Regional Health Authority and will conclude at the end of 2015.
OBJECTIVE OF THE STUDY: To test the hypothesis that 6 months DAPT (Dual anti-platelet therapy) after second generation DES (Drug Eluting Stent) implantation in STEMI (ST elevation Myocardial Infarction) is not inferior to 12 months DAPT in terms of clinical outcomes (composite endpoint of all-cause mortality, any MI, any revascularization, stroke and major bleeding at 18 months after randomization). The trial will incorporate two registers studying respectively the safety outcomes of Bivalirudin and Prasugrel combination and Bivalirudin and Ticagrelor combination at 2 and 30 days. Finally the trial design permits assessment of the clinical outcomes after primary PCI for treatment of STEMI with the new Resolute Integrity (Medtronic Santa Rosa Ca, USA) stent at 30 days and 6 months.
The main purposes of this study are: - to describe the prevalence of peripheral artery disease (including lower extremity artery disease, carotid artery disease, renal artery disease, and abdominal aortic disease) in patients with acute myocardial infarction in comparison to control subject from the general population, - to evaluate the association of peripheral artery disease with glucometabolic status in patients with acute myocardial infarction, - to assess the prevalence of type D personality in patients with acute myocardial infarction com pared to control subjects from the general population, - to examine the prognostic value of peripheral artery disease in patients with acute myocardial infartion, and - to evaluate the prognostic value of type D personality in patients with acute myocardial infarction.
This study explores the hypothesis that wearable defibrillators can impact mortality by reducing sudden death during the first three months after a heart attack in persons with high risk for life-threatening arrhythmias.
Coronary artery stents have improved the safety and efficacy of percutaneous coronary intervention for coronary artery disease. Drug-eluting stents have been shown to decrease neointimal hyperplasia and to reduce the rate of restenosis and target-lesion revascularization as compared to bare-metal stents. Drug-eluting stents consist of a metallic platform and a therapeutic substance that is usually released from a polymer matrix. A previous study utilizing a bioresorbable polymer has demonstrated a favorable safety and efficacy profile in a large-scale clinical trial as compared to a first-generation druf-eluting stent (LEADERS trial). The objective of the study is to compare the safety and efficacy of a sirolimus-eluting stent with a biodegradable polymer with an everolimus-eluting stent with a durable polymer in a prospective multicenter randomized controlled non-inferiority trial in patients undergoing percutaneous coronary intervention in routine clinical practice.
On a population of patients followed by an office-based cardiologist and treated with eplerenone, the objectives of the survey are: - To describe the characteristics of the population treated. - To describe the methods of use of eplerenone (posology, duration of treatment, medicinal combinations). - To describe the follow-up methods of the treatment. - To describe the possible interruptions of the treatment
When a patient has a heart attack, a blockage occurs in a coronary artery that delivers oxygen to the heart muscle. The heart muscle may weaken, causing heart failure. The body naturally makes a protein called insulin-like growth factor-1 (IGF-1) that may protect the heart muscle cells from dying and may prevent heart failure or lessen the damage that occurs. IGF-1 is also available as a drug called mecasermin. In this study, heart attack patients will be given either a dose of mecasermin or a placebo (inactive treatment) after their coronary artery has been opened by a stent. The purpose of the study will be to evaluate the safety of the therapy and to test if the therapy will prevent or lessen heart failure by evaluating a cardiac magnetic resonance imaging (MRI) taken one day and eight weeks after the heart attack.
This purpose of this research project is to test the diagnostic accuracy (i.e., sensitivity, specificity, positive and negative predictive value, and receiver operator curve area under the curve) of cardiac computed tomography (CT) perfusion as compared to the best non-invasive test of blood flow -- cardiac positron emission transmission (PET) perfusion imaging. The primary outcome of the study is to determine the CT perfusion technique with the highest overall diagnostic accuracy measured by the highest area under the receiver operator curve. The investigators will test 4 different CT perfusion techniques. (A) Qualitative, visual inspection of the contrast-enhanced CT images (B) Enhanced voxel distribution analysis (C) Rate of myocardial contrast enhancement analysis (D) Quantitative heart blood flow using a distributed 2-region analysis A second aim is to reduce the radiation dose needed to maintain CT perfusion diagnostic accuracy. Using the CT perfusion data, the investigators will model the minimal number of cardiac cycle radiation exposures needed to keep the diagnostic accuracy similar to the full data set. A third aim is to test the incremental diagnostic accuracy of CT angiography plus CT perfusion to identify regions of low blood flow as compared to PET perfusion alone.
