Active clinical trials for "Infarction"

There are two types of acute coronary syndrome (ACS): ACS with persistent ST segment elevation (ACS ST +) and ACS without ST segment elevation (non-ST + ACS). The incidence of non-ST + ACS is increasing and currently accounts for the majority of myocardial infarction (MI) hospitalizations, while that of ST + ACS is declining. Complications of MI, which include rhythm and conduction disturbances, are mainly associated with ACS ST +. It is recognized that these complications can occur during non-ST + ACS, but with less frequency. This frequency is not clearly established, and has been the subject of few studies. Recent studies in this direction suggest that the frequency of rhythmic complications is low during non-ST + ACS. However, the data collected concerns inter-hospital transport. The aim of the study is to estimate the frequency of occurrence of potentially fatal rhythmic complications in patients admitted to the emergency room and to the cardiology department for non-ST + ACS.

The aim of this study is to determine in patients with a recent lacunar strokes (<15 days), the natural history of cognitive disturbances and disability.

The primary aim of the study is to investigate new cardiac biomarkers and algorithms to diagnose acute coronary syndrome in patients with suspected acute myocardial infarction.

The purpose of this study is to determine the prevalence of plaque disruption and to assess the composition of disrupted plaques in patients with myocardial infarction (MI) and non-obstructive coronary artery disease (CAD) using optical coherence tomography (OCT). Additionally, cardiac magnetic resonance imaging (CMR) will be used to detect myocardial abnormalities, which will be correlated to OCT findings to gain insight into the mechanisms of MI in patients with non-obstructive coronary artery disease (i.e. "open arteries").

AMIPE is both a retrospective and prospective study which was designed in order to collect data of patients with acute coronary syndromes and myocardial injury and to improve the knowledge about these conditions.

The HARP study is a multi-center, diagnostic observational study employing standardized imaging protocols in patients with MINOCA (MI with Non Obstructive Coronary Arteries) to determine the underlying diagnosis in each participant. Participants will be followed for recurrent clinical events, every 6 months, for a maximum of 10 years.

Inflammation drives atherosclerotic plaque rupture triggering most acute coronary syndromes. Despite advances in diagnosis and management of atherosclerosis, patients with myocardial infarction (MI) remain at increased risk of recurrent events. The RIPPLE study aims to examine the relationship between residual coronary inflammation detected by 68Ga-DOTATATE PET in patients treated for MI to long-term plaque progression measured by CT coronary angiography (CTCA). The association between infarct-related myocardial 68Ga-DOTATATE PET and myocardial function and viability will also be assessed.

The purpose of this registry is to address optimal platelet inhibition during the early management of MI patients prior to coronary angiography or CABG.

The purpose of this observational study is to assess predictors of in-hospital mortality in patients with acute myocardial infarction admitted to Belgian hospitals.

Cardiac troponin is central to the diagnosis of myocardial infarction and high-sensitivity cardiac troponin (hs-cTn) assays are the preferred choice for the assessment of patients with suspected acute coronary syndrome. Since the introduction of hs-cTn assays in Europe in 2010, most hospitals have switched from contemporary sensitive cardiac troponin assays to a hs-cTn assay. The implementation of hs-cTn assays has led to an increase in the number of patients identified with myocardial injury. Although both hs-cTnI and hs-cTnT assays are recommended in current guidelines, the impact of switching from a hs-cTnI assay to a hs-cTnT assay on clinical practice is unknown. At this point, no studies have evaluated the impact of implementing sex-specific hs-cTnT thresholds on the diagnosis of myocardial infarction and outcome in clinical practice. The investigators propose to determine the proportion of patients with and without myocardial injury admitted to the hospital before and after implementation of a hs-cTnT assay and to evaluate the impact on investigations, care and clinical outcomes in consecutive patients with suspected acute coronary syndrome.
