Active clinical trials for "Myocardial Infarction"

The aim of SOCCER is to evaluate the effects of treatment with supplemental O2 before and during acute balloon angioplasty (PCI) for patients with ST-elevation myocardial infarction (STEMI). One hundred STEMI patients are randomized in the ambulance to either standard O2 treatment (10 l/min) or no supplemental O2, to be given until the end of the acute PCI. Cardiac magnetic resonance imaging and echocardiography during the hospital stay is used to assess infarct size and myocardial performance. All patients are followed for 6 months. At 6 months, perceived health and NT-proBNP are recorded for all patients, and an additional echocardiography is performed. The primary endpoint is the fraction of myocardium saved with the acute PCI. The secondary endpoints include the pain difference between inclusion time and start of PCI and myocardial performance on echocardiography.

Acute coronary syndromes (ACS) are still associated with high morbidity and mortality, despite several improvements in their management. This may indicate that important pathogenic mechanisms contribute to both stable and unstable atherosclerotic disease mechanisms. Based upon previous research, the investigators believe that providing a block in the damaging inflammatory loop though short term inhibition of Interleukin-6 receptor signalling, could be an attractive therapeutic target in ACS; and of particular interest in patients with non-ST elevation myocardial infarction (NSTEMI), a disease often characterized by widespread coronary inflammation with multiple unstable plaques. The investigators hypothesize that a single administration of the anti-Interleukin 6 receptor antagonist Tocilizumab, in patients with NSTEMI, may interrupt the self-perpetuating inflammatory loops which could improve plaque stability, with potential secondary beneficial effects on myocardial damage. This will be investigated in a randomized, double blind, placebo-controlled study, including a total of 120 patients.

Exercise training, as part of cardiac rehabilitation, is effective in improving functional capacity and quality of life in patients with coronary artery disease. Other cardiovascular and non-cardiovascular benefits have been reported, namely in glucose metabolism, skeletal muscle function, oxidative stress, vascular function, pulmonary circulation, ischaemia-reperfusion lesion and ventricular remodelling. However, the benefit of exercise training on systolic and diastolic function is controversial especially after acute myocardial infarction where no longitudinal study has evaluated diastolic function using modern echocardiographic parameters. The hypothesis is that a structured program of exercise training can improve systolic and diastolic function in patients after myocardial infarction.

To determine whether higher as compared with lower maintenance doses of clopidogrel can adequately improve the degree of platelet inhibition in carriers of a reduced-function CYP2C19 allele.

The purpose of the study it to evaluate whether primary percutaneous coronary intervention (primary PCI) with a new thrombectomy device as compared to primary PCI without thrombectomy increases minimal flow area after stenting for treatment of patients presenting with ST-segment elevation myocardial infarction (STEMI) as assessed by OFDI.

The objective of the present study is to establish the safety and efficacy of Prochymal® following first acute myocardial infarction.

This is a double-blinded randomized placebo controlled trial investigating the role of upstream 80mg Atorvastastin-calcium in patients undergoing percutaneous intervention for acute STEMI.

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 purpose of this study is to determine whether acadesine is effective in reducing the cardiovascular and cerebrovascular adverse events in high-risk participants undergoing CABG surgery.

This study is aimed to investigate whether treatment with Telmisartan is more effective than Candesartan in reducing the ischemic cardiovascular events in high-risk patients with cardiovascular disease.
