Filter by:Thirty (30) patients with chronic ischemic left ventricular dysfunction secondary to MI scheduled to undergo cardiac catheterization will be enrolled in the study. This is a phase II study intended to gain additional safety and efficacy assessments among two dose levels previously studied in a phase I setting.
Positron emission tomography (PET) scans can be used to evaluate whether parts of the heart muscle are alive but receiving inadequate blood supply. This study involves the use of two radiotracers that will measure whether heart muscle cell are alive and quantify the blood supply to the heart muscle.
1. In chest pain patients with suspected acute coronary syndrome, a 2-hr delta Troponin-I as measured by the i-STAT immunoassay reliably identifies and excludes an acute myocardial infarction. 2. In chest pain patients with suspected acute coronary syndrome whose baseline troponin is above the 99th percentile but less than 0.2ng/ml, a 2hr delta Troponin-I as measured by the i-STAT immunoassay accurately discriminates between acute myocardial infarction and non-acute myocardial infarction troponin elevations.
Ferumoxytol is an example of a 'smart' magnetic resonance contrast agent that consists of ultrasmall superparamagnetic particles of iron oxide (USPIOs) and is avidly taken up by macrophages. Through a previous work, the investigators have established that USPIOs can identify inflammation in the wall of abdominal aortic aneurysms and that this is associated with a three-fold increase in the rate of aneurysm growth. The utility of ferumoxytol for imaging cardiovascular inflammation in other areas of the body has yet to be established but Dr Alam has established uptake of USPIOs in the penumbra and infarct zone of the myocardium in patients with a recent myocardial infarction. The investigators wish to assess USPIO uptake in patients with recent acute myocardial infarction and identify the time course and determinants of cellular tissue inflammation. This will be the first clinical study to examine the ability of USPIOs to image myocardial inflammation following acute myocardial infarction.
The purpose of the INSPIRE-ELR study is to characterize arrhythmias in post MI low EF (≤35%) patients in the acute phase (at discharge from hospital after index MI) and chronic phase (at 8-10 weeks after index MI) and to correlate with patients at high risk of all-cause mortality or sudden cardiac death (SCD) at 1 year.
To examine the efficacy and safety of dual antiplatelet therapy (DAPT) including cilostazol (Pletaal OD Tablet ®) in comparison with antiplatelet monotherapy (excluding cilostazol) for secondary prevention of ischemic stroke in high-risk patients for stroke
This is a Prospective, randomized (1:1), active control, single-blind, non-inferiority, European multicenter clinical trial. The primary objective of this study is to assess the neointimal healing score (as evaluated by intra-coronary OFDI) in patients with ST-elevation Myocardial Infarction (STEMI) and treated with Abbott Vascular ABSORB everolimus eluting bioresorbable vascular scaffold (BVS) at 6 months follow-up by comparing with a metallic drug eluting stent (XIENCE). Furthermore, the safety and feasibility of implanting ABSORB BVS in patients with STEMI is assessed. It is hypothesized that acutely and at 6 months follow-up implantation of the ABSORB fully bioresorbable everolimus-eluting scaffold is at least as safe as implantation of metallic drug-eluting stent, and that at late follow-up the ABSORB scaffold could improve the arterial healing process and potentially reduce late stent thrombosis in patients presenting with STEMI. This is a preparatory trial in anticipation of a major outcome study.
To characterize and estimate the size of different populations with a history of acute coronary syndrome in Sweden. To assess the burden of illness (co-morbidities, mortality rates healthcare resource utilization and atherothrombotic events) among patients with a history of myocardial infarction (MI) 1-3 years ago and additional risk factors for atherothrombosis.
This study explores the potential cardioprotective properties of danegaptide when administered to patients with ST-Segment elevation myocardial infarction.
In a double blinded, randomized, clinical trial of patients suffering from STEMI (ST-segment elevation myocardial infarction) or non-STEMI (non-ST-segment elevation myocardial infarction)compare the effect of 3 months of dietary supplement with bilberry extract on a range of parameters with prognostic importance in cardiovascular disease: lipids, inflammation, oxidative stress and heart function. Following inclusion of 8 individuals and as of February 12, 2014: Due to intolerance to "bilberry placebo powder" we have amended to the protocoll that the trial design is changed from blinded to open and that the bilberry arm of the trial carries on in an open design and that the control group will receive no dietary supplement.
