Filter by:The present feasibility study is designed to find out whether pre-treatment with the compound mangafodipir (PP-099) provides an additional reduction in myocardial infarct size in patients treated with primary percutaneous coronary intervention (PCI) during acute myocardial infarction (AMI).
The purpose of the study is to compare home-based aerobic interval training with supervised interval training performed in groups or on a treadmill at the hospital.
Stent study: Treatment of patients with acute myocardial infarction with drug eluting stents (DES) is effective but there remain concerns regarding the long-term safety and adverse effects on the adjacent arterial wall. The biolimus-eluting Biomatrix stent addresses the issues by incorporating modifications as a biodegradable polymer and a drug application solely to the abluminal stent surface. While clinical data about the biolimus-eluting stent show a favorable safety and efficacy profile, they require confirmation in a dedicated randomised trial in the subset of patients with STEMI. Therefore, the study is designed to compare the safety and efficacy of biolimus-eluting Biomatrix stent as compared to a bare metal stent of otherwise identical design in a prospective, multicenter, randomized, controlled superiority trial in patients with acute ST-elevation myocardial infarction. Stent and Plaque Imaging Substudy: In a substudy of the above mentioned stent trial, the investigators will perform a prospective, multicenter, longitudinal cohort study of 100 consecutive STEMI patients undergoing urgent coronary angiography and will employ high-resolution Optical Coherence Tomography (OCT) imaging technology and intra-vascular ultrasound and virtual histology (IVUS-VH) of the culprit STEMI lesions pre- and postprocedural as well as at a 13 months follow up. Assessment of vascular wall responses, including volumetric measurements of vessel, stent, lumen, peri-stent plaque, and intimal hyperplasia, indices of remodeling, stent expansion, and stent-vessel wall apposition in response to biolimus-eluting and bare-metal stent implantation will be performed. Moreover, IVUS, IVUS-VH and OCT will be performed in all three epicardial vessels in order to quantify and map the number, frequency and distribution of ruptured plaques at baseline and follow-up and quantify the morphological changes of ruptured and vulnerable plaques at baseline and follow-up and quantify the morphological changes over time in response to standard medical treatment. Therefore, new insight regarding the frequency, distribution, composition and evolution of coronary artery plaques and their prognostic impact on patients clinical outcome can be expected from the present study. Since patients suffer from a recurrent ischemic event rate of 5-10% during the first year, these findings may have important therapeutic implications for the medical treatment of affected patients to further reduce the risk of recurrence and improve prognosis.
The objective of this study is to measure the effect of an innovative training programme on the help seeking behaviour and helping rates of bystanders in medical emergencies.
In acute myocardial infarction cardiovascular magnetic resonance imaging can retrospectively detect the myocardium at risk and the irreversible injury. This allows for quantifying the extent of salvaged myocardium after reperfusion as a potential strong end point for clinical trials and outcome. The aim of the present study is to determine the prognostic significance and determinants of myocardial salvage assessed by CMR in reperfused ST-elevation myocardial infarction (STEMI).
The purpose of this study is to investigate the effects of postconditioning on myocardial reperfusion in patients with ST-segment elevation myocardial infarction.
This multi-center, randomized, controlled trial conducted in Emergency Departments (ED) compares computed tomography (CT) coronary angiography with the traditional approach (usual care) for low- to intermediate-risk chest pain patients. The primary objective is to estimate the rate of major cardiac events (heart attack or cardiac death) within 30 days in trial participants in Group B who were not found to have significant coronary artery disease by CT coronary angiography. Additional evaluations will comprise health care utilization assessments, including length of hospital stay and re-admissions, cost analysis, and 1-year post-triage/presentation major cardiac event rates.
The purpose of this study is to compare the effects of the consumption of two different dietary patterns (low fat versus Mediterranean Diet) on the incidence of cardiovascular events of persons with coronary disease.
The purpose of this study is to determine whether the intravenous infusion of sodium nitrite safely prevents ischemia-reperfusion injury in subjects with acute myocardial infarction resulting in improved left ventricular function.
Study objectives: To assess the effects of postconditioning on infarct size in patients with ST-elevation infarction referred to PCI. Study design: Prospective, randomized, open-label study with blinded endpoint evaluation. Included patients will be randomly allocated to postconditioning or control. Patients with symptoms of acute myocardial infarction of less than 6 hours duration fulfilling ECG criteria for primary PCI are eligible. PCI follow established routines. In postconditioning patients, additional, short (1 min), intermittent balloon occlusions will be applied after initial opening of infarct related artery. After this intervention, PCI proceeds routinely with stent implantation. In the control group, stent implantation after initial opening proceeds as usual. Primary endpoint is final infarct size, determined by MRI after 4 months. 260 patients will be included. Follow-up is 1 year. Inclusion period: 18 - 24 months. Clinical implications: Reperfusion therapy, administered as early as possible after start of symptoms, has improved the prognosis in acute ST-elevation myocardial infarction. Still, however, many patients suffer large infarctions, subsequently with an increased risk of heart failure, arrhythmias, and death. In pilot studies, mechanical postconditioning has been shown to reduce infarct size and thus potentially improve prognosis. However, the effect of postconditioning must be confirmed in larger clinical trials before implemented in routine treatment.
