Filter by:The objective of this study was to evaluate the effectiveness of a FCEM-focused hybrid CR program for survivors of myocardial infarction (MI). The study sought to compare the long-term impact of FCEM-based intervention with a standard CR program in terms of mortality rates and different aspects of health related quality of life (HRQoL), which includes soft outcomes such as levels of stress, anxiety, psychological distress, quality of life (QoL), and hard outcomes such as the percentage of ejection fraction (EF), independent functioning, and functional exercise capacity status.
SONOBIRDIE Trial is a randomized, single-blind, sham-controlled study designed for a demonstration of the safety and effectiveness of sonolysis (continual transcranial Doppler (TCD) monitoring) in reduction of risk of stroke or transient ischemic attack (TIA), brain infarctions and cognitive decline using a 2-MHz diagnostic probe with a maximal diagnostic energy on the reduction of risk of brain infarctions by the activation of endogenous fibrinolytic system during carotid endarterectomy (CEA) in patients with ≥ 70% symptomatic or asymptomatic internal carotid artery stenosis. The sample size is based on an expected 2.5% reduction of ischemic stroke, TIA, and death during the 30-day postoperative period in the sonolysis group (estimated prevalence, 1.5 %) compared to the control group (estimated prevalence, 4 %). Pre-study calculations showed that a minimum of 746 patients in each group is needed to reach a significant difference with an alpha value of 0.05 (two-tailed) and a beta value of 0.8 assuming that 10 % would be lost to follow-up or refuse to participate in the study. Consecutive patients will be assigned to the sonolysis or control group by a computer-generated 1:1 randomization. In patients randomized into sonolysis group, middle cerebral artery segment in a depth of 55 mm will be continuously monitored during intervention using a diagnostic 2-MHz TCD probe with a maximal diagnostic energy. In patients randomized into control group, the TCD probe will be fixed in a required position using a special helmet as in sonolysis group patients, but middle cerebral artery segment in a depth of 55 mm will be only localized using a diagnostic 2-MHz TCD probe with a maximal diagnostic energy and the TCD monitoring will be stopped afterwards. Confirmation of the investigators hypothesis that sonothrombolysis is able to activate endogenous fibrinolytic system during CEA with consecutive reduction of ischemic stroke, TIA or death, and the number and volume of brain infarcts, can lead to the increase of the safety of CEA in patients with internal carotid artery stenosis. The investigators can presume that up to 50% of patients indicated for CEA can be treated using these methods in the future.
To evaluate the efficacy and safety of embolic protection devices to reduce ischemic brain injury in patients undergoing surgical aortic valve replacement (AVR).
The purpose of this registry is to evaluate long-term clinical events in patients with acute myocardial infarction who were treated with percutaneous coronary intervention. Although numerous articles have been published by using nationwide Korean myocardial infarction registries, such as the Korea Acute Myocardial Infarction Registry (KAMIR), limitation of previous registries is that these have little data beyond the first year of MI. Therefore, current registry was designed to assess long-term clinical events in patients with acute myocardial infarction. Because most of myocardial infarction patients were treated by revascularization in real world of Korea, this registry limits the inclusion criteria to patients who were treated with percutaneous coronary intervention to reduce the bias.
Proven treatments exist that improve quality of life and reduce the risk of repeat heart attacks or death amongst persons who have already had one heart attack. These treatments include medications and supervised cardiac rehabilitation programs. Unfortunately, research shows that many people who have had a heart attack do not stick with these treatments and therefore cannot benefit. This quality improvement research program seeks to understand the impact of interventions that could be readily implemented at scale by entire health systems or organizations wishing to improve adherence to proven treatments. Specifically, the trial will test whether providing Ontario-based patients (and their health professionals) with repeated educational reminders delivered via post and phone will help improve the use of medications or attendance at cardiac rehabilitation. During the project, the types of patients who are most responsive will be identified as will the most cost-effective strategy for delivering reminders. The trial team are partnering in this project with health system decision makers who have an interest in using the results to create standard operating procedures that could benefit patients across the province.
The objective of the study is to evaluate the safety and the potential therapeutic effects per dose of Cordstem-ST Intravenous Transplantation in Cerebral Infarction subjects
Cardiovascular events are the main cause of mortality in diabetic patients ,on the other hand,during an acute myocardial infarction(AMI),hyperglycemia increases mortality and is related to different pathophysiologic processes. More important evidence regarding the effect of glycemic control on AMI patients prognosis is contradictory,and the potential benefits of dipeptidyl peptidase-4 inhibitors(DPP4-i) in this setting is unknown. The aim of this study is to assess the presence of pleiotropic effects of DPP4-i(sitagliptin or saxagliptin) and their relationship with glycemic control during in-hospital phase of AMI.
The degree to which elevated mortality associated with weekend or night-time hospital admissions reflects poorer quality of care ('off-hours effect') is a contentious issue. We examined if off-hours admissions for primary percutaneous coronary intervention (PPCI) were associated with higher adjusted mortality and estimated the extent to which potential differences in door-to-balloon (DTB) times—a key indicator of care quality for ST elevation myocardial infarction (STEMI) patients—could explain this association. Nationwide registry-based prospective observational study using Myocardial Ischemia National Audit Project data in England. We examined how off-hours admissions and DTB times were associated with our primary outcome measure, 30-day mortality, using hierarchical logistic regression models that adjusted for STEMI patient risk factors. In-hospital mortality was assessed as a secondary outcome. Our study found that higher adjusted mortality associated with off-hours admissions for PPCI could be partly explained by differences in DTB times.
Detecting scarred heart muscle is important to diagnose and treat of a wide variety of heart conditions. Magnetic resonance imaging (MRI) can assess scarred heart muscle but it is time consuming, contraindicated for some patients and not tolerated by others. Computed tomography (CT) imaging has the potential to provide a rapid comprehensive assessment of the heart. This study will assess CT imaging of the heart muscle of patients who have previously undergone MRI of their heart. Using a state of the art CT scanner the investigators will develop a low radiation dose protocol to identify scarred heart muscle. The investigators will use and develop software techniques to analyse these images. This will enable us to develop a new way to identify and measure scarred heart muscle that will benefit patients with heart disease.
Background: Colchicine is an old well-known venerable drug routinely used in gout attacks for instance. More recnetly it is regularly use in the treatment of pericarditis. It couls exert antiiflammatory effects targeting the adverse inflammation occuring incase of acute myocardial infarction, which is involved in poor outcomes or longer stay at hospital. Endpoints: - Main endpoint: AUC CRP during the initial hospital stay - Secondary endpoints: - Clinical: oucomes - Imaging: ETT, MRI - Biological: various biomarkers Method Randomized, controled, open-labbelled, comparing two parallel arms: conventionnal optimal treatment versus conventionnal optimal treatment + colchicine
