Active clinical trials for "Myocardial Infarction"

The development of symptomatic heart failure is frequently preceded by a pre-clinical period of structural remodeling in the heart. The remodeling process driving this transition, however, remains poorly understood. The investigators hypothesize that imaging the diffusion of water in the heart with MRI will allow its microstructure to be resolved. The investigators further hypothesize that the characterization of microstructural changes in the heart will help elucidate the pathogenesis of heart failure and the transition from a compensated to a decompensated state. Patients with recent myocardial infarcts and left ventricular hypertrophy, who are at risk for the development of heart failure, will be enrolled. The participants will undergo serial diffusion tensor MRI (DTI) imaging of the heart to characterize changes in myocardial microstructure over time.

The aim of the study is to examine whether treatment with extracorporeal life support (ECLS) in addition to revascularization with percutaneous coronary intervention (PCI) or alternatively coronary artery bypass grafting (CABG) and optimal medical treatment is beneficial in comparison to no ECLS in patients with severe infarctrelated cardiogenic shock with respect to 30-day mortality

The purpose of the study is to see if positron emission tomography and magnetic resonance imaging (PET/MRI) with an investigational drug called [18F]DPA-714 will show inflammation in the brain after a heart attack. This study may help physicians and researchers better understand the role of brain inflammation in heart disease and develop new treatments to protect the brain.

The study aims to determine the feasibility and clinical utility of incorporating precision medicine approaches, incorporating both cytochrome P450 2C19 (CYP2C19) genotyping and platelet reactivity phenotyping, with standard of care for patients with acute coronary syndromes (ACS), post PCI.

This study is aimed to investigate if the bivaliruding with prolonged full dose infusion after PCI is superior to heparin alone in reducing 30-day mortality or major bleeding for patients with STEMI treated with emergency PCI. A total of 6000 STEMI patients will be enrolled and randomly assigned to receive bivalirudin or heparin during emergency PCI in a 1:1 ratio. This study will provide key evidence for peri-operative anticoagulant therapy decisions in STEMI patients.

Sarcoidosis is a multisystem granulomatous disease of unknown cause that can affect any organ in the body, including the heart. Granulomatous myocarditis can lead to ventricular dysfunction and ventricular arrhythmias causing significant morbidity and mortality. Immunosuppressive therapy (IST) has been shown to reverse active myocarditis and preserve left ventricular (LV) function and in some cases improve LV function. In addition, IST can suppress arrhythmias that develop due to active myocarditis and prevent the formation of scar. The potential role of cardiac biomarkers, including brain natriuretic peptide (BNP), atrial natriuretic peptide (ANP), and cardiac troponins, in detecting active myocarditis is limited and studies have been disappointing. At present, there are no biomarkers to detect active myocarditis and the use of advanced imaging modalities (FDG-PET) for assessing and monitoring active myocarditis is not feasible or practical and is associate with high radiation exposure. As such, a biomarker that is reflective of active myocarditis and that is cardiac specific will assist physicians in assessing the presence of active myocarditis to guide therapeutic decisions and to assess response to therapy which can limit further cardiac damage. Cell free DNA (cfDNA) are fragments of genomic DNA that are released into the circulation from dying or damaged cells. It is a powerful diagnostic tool in cancer, transplant rejection and fetal medicine especially when the genomic source differs from the host. A novel technique that relies on tissue unique CpG methylation patterns can identify the tissue source of cell free DNA in an individual reflecting potential tissue injury. We will be conducting a pilot study to explore the utility of this diagnostic tool to identify granulomatous myocarditis in patients with sarcoidosis.

The AMISLEEP study is nested in the "FRENCHIE" registry. The objective is to use routine clinical and polygraphic data to capture SDB/SAS (Sleep Disordered Breathing/Sleep Apnea Syndrome) physiological heterogeneity in relation to clinically relevant cardiovascular outcomes. Specifically, the investigators hypothesize that unique clusters (phenotypes) of patients could be identified by applying unsupervised learning methods to these data and that the clusters would be differentially associated with risk of adverse cardiovascular outcomes (ACS), TIA, stroke or death). The ultimate goal is to identify patients more at risk that could be included in interventional studies that would test whether SDB/SAS treatment can improve this risk.

This study aims to compare the acute thrombogenecity and frequency of neoatherosclerotic lesions and other aspects of long term arterial healing such as the frequency of malapposed and uncovered stent struts at 3 years among patients treated with either a biodegradable polymer everolimus-eluting stent (Synergy) or a durable polymer everolimus-eluting stent (Xience Alpine) for STEMI.

The aim of this study is to investigate whether near-infrared guided percutaneous coronary intervention in patients with acute myocardial infarction provides improved stent strut coverage at six months compared to conventionally angiography guided percutaneous coronary intervention.

This is a study in adults who had a heart attack (myocardial infarction). The purpose of this study is to find out whether a medicine called empagliflozin helps to lower the chances of having to go to the hospital for heart failure and whether it lowers the chances of dying from cardiovascular disease. People who are in hospital may join the study soon after being treated for their heart attack. Participants are put into 2 groups by chance. One group takes 1 empagliflozin tablet a day. The other group takes 1 placebo tablet a day. Placebo tablets look like empagliflozin tablets but do not contain any medicine. All participants continue their standard treatment. Empagliflozin belongs to a class of medicines known as SGLT-2 inhibitors. Empagliflozin is a medicine that helps people with type 2 diabetes to lower their blood sugar. Researchers think that empagliflozin might also help people after heart attack who are at risk for heart failure, whether or not they have diabetes. Participants are in the study for about 1 to 2 years. During this time, there are about 4 visits inperson, 2 visits are done either by phone or by use of an mobile application. Results between the empagliflozin and placebo groups are compared. The doctors also regularly check the general health of the participants.
